I worked as an intern in xx New Campus Project Department of xx Construction Co., Ltd. for XX months, mainly undertaking construction work. This is the first time that I officially stepped into the society, set foot on my job and started a completely different life from the past. Go to and from work at the specified time every day, and finish the work tasks seriously and on time during work, and never be hasty and perfunctory. Be responsible for yourself, your work and the reputation of the school.
The so-called practice is the criterion for testing truth. Through practice, I have closely observed the whole building construction process and learned a lot of applicable and specific construction knowledge, which I seldom contact and pay attention to at school, but it is also very important and basic knowledge. Let me further understand the difference between theory and practice.
Through this internship, I have a perceptual knowledge of the major I am about to engage in from practice, which has laid a solid foundation for future professional study. Not only let us learn a lot of knowledge that we can't learn in class, but also broaden our horizons and increase our knowledge, laying a solid foundation for us to better apply what we have learned to practical work in the future. Through production practice, I can get more in-depth contact with professional knowledge, further understand the importance of reasonably controlling the cost of construction projects, understand the problems existing in the process of project construction management and the difficult problems that conflict between theory and practice, and write an internship report, so that I can learn to comprehensively use what I have learned and improve my ability to analyze and solve professional problems. Through this internship, I learned a lot:
A, steel structure engineering
(a), foundation slab and foundation beam steel binding
1. According to the pop-up reinforcement position line, the lower reinforcement shall be laid first. Model essay on graduation practice report of civil engineering. According to the stress of the bottom plate, decide which direction the lower reinforcement is below. Generally, short tendons are laid first, and then long tendons are laid.
2. Put the mortar pad of the concrete protective layer of the bottom plate, the thickness of the pad is equal to the thickness of the protective layer, which can be reduced by the distance of 1m or so, and even the mortar pad can be replaced by iron.
3. If there is a foundation beam on the bottom plate, it can be bound and shaped in sections and then installed in place, or it can be bound and shaped on the spot according to the beam position line.
4. When there are binding joints for floor reinforcement, the lap length and lap position of reinforcement shall meet the requirements of construction specifications, and the lap joints of reinforcement shall be fastened with iron wires at the middle and both ends. If welded joints are used, in addition to sampling according to the welding regulations, the joint position should also comply with the construction specifications.
5. According to the played position line of the wall column, the steel dowel inserted into the foundation of the wall column should be firmly bound, the depth of the inserted foundation should meet the design requirements, and the length of the sling should not be too long. Measures should be taken to ensure that the sling is vertical and will not be skewed, dumped or displaced.
(2) Binding of beam reinforcement
1. Draw the stirrup spacing on the beam side formwork and place the stirrups.
2. First, pass through the longitudinal stress reinforcement and bending reinforcement at the lower part of the main girder, and separate the stirrups one by one according to the drawn spacing; Wear the longitudinal stressed steel bars and bent steel bars at the lower part of the secondary beam, and set stirrups; Put the scissors of primary and secondary beams; Tie up the installation stud and stirrup at regular intervals; Adjust the stirrup spacing, make the spacing meet the design requirements, tie the stud, then tie the main reinforcement, and coordinate the primary and secondary beams at the same time.
3. The upper longitudinal reinforcement of the frame beam should run through the middle node, and the anchorage length of the lower longitudinal reinforcement of the beam should meet the design requirements.
4. The stirrup hooks at the lap joint are staggered and bound in the beam. The stirrup hooks are 135, and the length of the straight part is 10d. If the closed hoop is made, the length of one-sided weld is 5d.
5. The first stirrup at the beam end should be set 50㎜ away from the edge of column node. The stirrup at the joint of beam end and column should be encrypted to meet the design requirements.
6. Lapping of beam reinforcement: When the diameter of the stressed reinforcement of the beam is equal to or greater than 22㎜, welded joints shall be adopted; When it is less than 22㎜, binding joints can be used, and the lap length should comply with the regulations. The distance between the end of the lap length and the bend of the steel bar should not be less than 10 times the diameter of the steel bar. The joint should not be located at the bending moment of the member. In the tension zone, the ends of the binding joints of Grade I steel bars should be hooked (Grade II steel bars are not hooked), and the lap joints should be fastened at the center and both ends.
(3), plate steel binding
1. Clean up the sundries on the template, draw the main reinforcement on the template with chalk, and allocate the spacing between the reinforcement.
2. According to the planned spacing, put the main reinforcement first, and then put the distribution reinforcement. Embedded parts, electrical conduits and reserved holes shall be installed in time. Two-way stress plate, short-term reinforcement below, long-term reinforcement above.
3. When the cast-in-place slab has a slab beam, the slab beam reinforcement shall be bound first, and then the slab reinforcement shall be placed.
4. Mortar pad is placed under the reinforcement, and the spacing is 1. 5 million. The pad thickness is equal to the protective layer thickness, which should meet the design requirements. When there is no requirement in the design, the thickness of the protective layer of the slab should be 15㎜, and the requirements for the lap length and lap position of reinforcement are the same as those of the beam mentioned above.
Second, the template project
(a), template preparation before installation and installation considerations
1. After the plates enter the site, count the quantity and check the model according to the design requirements of the switchboard;
2. The template should be lifted smoothly. It is forbidden for the operator to ascend with the template.
3. Before clamping, the sundries in the template must be cleaned up;
4. The contact surface between formwork and concrete should be cleaned and coated with isolation agent. After the template coated with isolation agent fails due to rain or other factors, the isolation agent must be brushed;
5. When installing the formwork, follow the principle of first inside and then outside, install the transverse wall first, and then install the longitudinal wall in place;
6. After the formwork is installed in place, measures can be taken to seal the gaps and connection parts (the beam steel formwork is bonded with adhesive tape and the column formwork is bonded with double-sided tape) to prevent slurry leakage and dislocation.
(2) Installation of formwork
1. Wall and column formwork installation:
Pop up the edges and control lines of wall and column templates on the base, and then put the templates in place. Temporarily fix the template first, adjust the template mouth according to the template control line, and do temporary fixing. After the formwork is reinforced, adjust the verticality of the formwork by supporting the messenger wire, and finally reinforce the formwork. After reinforcement, check its position and verticality for the second time to ensure the accurate size.
2. Beam and plate template installation:
(1) Pop up the elevation control line (line 50) on the wall and column, and according to the elevation control line, pop up the lower elevation control line of beam slab template on the wall and column.
(2) Placement of beam-slab formwork columns: The columns of beam-slab formwork are installed in strict accordance with the designed spacing and position, and are in the same position as the lower columns, with 50 planks under the columns.
(3) Beam slab arching: firstly, adjust the supporting height at both ends of the beam and around the slab according to the design elevation, and then draw a horizontal line; According to the bulging height (1‰-3‰ beam-slab span) and the position of each intermediate support, the bulging height of each support is calculated. Finally, after adjusting the height of each support, lay the beam bottom formwork or the main keel of the floor.
3. Embedded parts and reserved holes:
On the completed beam-slab formwork, the exact positions of embedded parts and reserved holes are determined according to the requirements of drawings, and the lines are clearly marked, and then the templates of embedded parts and reserved holes are fixed on the beam-slab formwork with nails.
4. Template processing of beam-slab post-cast strip:
When supporting the formwork at the post-cast strip of the roof, it will be disconnected from the whole beam slab formwork. When dismantling the formwork, the formwork at the post-cast strip shall not be dismantled. After the concrete pouring is completed, the steel bars are protected with bamboo woven boards from above.
5. The template installation of roof post-cast strip should be coated with isolation agent;
(1) isolators are all water quality isolators, mainly including seaweed steel and cauliflower.
(2) Side formwork of wall, column and beam: After processing or dismantling, a layer of isolating agent shall be painted for later use. Top plate: After the formwork is installed, brush one layer with roller brush. In case it rains, brush it again. Template inspection during concrete pouring:
During concrete pouring construction, the formwork shall be monitored and inspected by designated personnel, and the problems found shall be handled in time; After the concrete pouring of walls and columns is completed, the verticality of walls and columns should be checked again. The quality of concrete has a great influence on the safety and cost of the structure, so we must pay enough attention to the construction quality of concrete in the construction.
(3) Pay attention to when the template is removed.
Non-load-bearing side formwork can only be removed when the strength of concrete can ensure that its surface and edges and corners are not damaged by formwork removal; The bearing formwork can only be removed after the concrete reaches the formwork removal strength; Before concrete form removal, you must fill in the form removal application form and agree to form removal.
Demolition of side formwork of walls, columns and beams: the strength of concrete shall ensure that its surface and edges and corners are not damaged by formwork removal, and the general strength reaches 1. About 0mpa can be removed. The formwork removal time should be controlled according to the concrete strength grade, ambient temperature or curing test blocks under the same conditions.
Dismantling the bottom formwork of beam and slab: when the span of beam and slab is less than 2m, the concrete strength reaches 50% of the design strength; In the range of 2-8 meters, its strength reaches 75% of the design strength; Concrete larger than 8m can only be removed when it reaches 100% of the design strength.
Dismantling of cantilever members: No matter the span length, concrete can only be dismantled after it reaches 100% of the design strength.
Before the beam bottom formwork and plate formwork are dismantled, the carpentry foreman shall fill in the form removal application form, and the operator shall provide the strength report of the concrete block with the same conditions, which can only be dismantled after being approved by the project chief engineer.
When dismantling the formwork at the angle of Yin and Yang, it is forbidden to pry it hard with a crowbar to avoid damaging the formwork and concrete surface and affecting the visual quality of concrete.
The beam-slab formwork of post-cast strip is disconnected from other beam-slab formwork during installation, and the formwork here can only be removed after secondary concrete pouring.
Dismantle the high steel pipe during formwork removal, and two people cooperate to prevent the steel pipe from forming impact load on the floor; Dismantled templates and supports shall be packed and transported away in time.
After the formwork of wall and column is dismantled, wooden boards should be used to protect the stair tread and the external angle of the passage in time.
Third, the concrete engineering
The quality of concrete has a great influence on the safety and cost of the structure, so we must pay enough attention to the construction quality of concrete in the construction.
(a) homework preparation:
Before pouring, the garbage, dirt and other sundries in the template and the oil stain on the steel bar should be removed, and check whether the cement pad of the steel bar is properly padded. If wooden formwork is used, it should be watered to make the formwork moist, and the column formwork should be closed to clean the mouth at a high level after removing sundries.
(2) concrete mixing:
Self-mixed concrete is used to prevent the temporary shortage of commercial concrete and mix sporadic concrete on site. Raw materials and mixture ratio should be consistent with commercial concrete.
1 The weighing standards of cement, sand and stone are fixed respectively according to the amount of various materials and the weight of vehicles determined by the mixture ratio. The water content of aggregate should be determined frequently, and the water consumption of mixture ratio should be adjusted in time to ensure the accuracy of adding water. Weigh it.
2 Loading sequence: generally, stone is loaded first, then cement is loaded, and finally sand is loaded. If admixture is needed, it should be added together with cement. Such as additives (water reducing agent, early strength agent, etc. ) When necessary, the powder should be pretreated, packed into small packaging bags (plastic bags are appropriate) according to the dosage of each plate, and added at the same time with the coarse and fine aggregates; The liquid form should be added to the mixer at the same time with water according to the dosage of each plate.
3. Mixing time: The shortest concrete mixing time shall be determined according to the requirements of construction specifications, and the mixing time shall be appropriately extended.
4 When the concrete begins to be mixed, the technical department in charge of the construction unit and the foreman shall organize relevant personnel to identify the slump and workability of the concrete, check whether it meets the requirements of the notice of mixture ratio, and then stir after adjustment.
(3) Early curing of concrete
Practice has proved that the common cracks in concrete are mostly surface cracks with different depths, mainly due to the sudden drop of temperature in cold areas caused by temperature gradient, which is easy to form cracks. Therefore, the thermal insulation of concrete is particularly important to prevent early cracks on the surface. From the point of view of temperature stress, thermal insulation shall meet the following requirements:
1. Prevent the temperature difference between the inside and outside of concrete and the slope of concrete surface, and prevent surface cracks.
2. In order to prevent concrete from freezing, the lowest temperature of concrete during construction should be not lower than the stable temperature of concrete during use.
3. Prevent the old concrete from supercooling, so as to reduce the constraint between the new and old concrete.
The main purpose of early curing of concrete is to maintain suitable temperature and humidity conditions, so as to achieve two effects. On the one hand, it can protect concrete from adverse temperature and humidity deformation and prevent harmful cold shrinkage and dry shrinkage. On the one hand, the hydration of cement goes smoothly to achieve the designed strength and crack resistance. Suitable temperature and humidity bars are interrelated. Thermal insulation measures often have a moisturizing effect on blood coagulation. Theoretically, the water content of fresh concrete can completely meet the requirements of cement hydration. However, due to evaporation and other reasons, it often causes water loss, thus delaying or preventing the hydration of cement, and the surface concrete is most easily and directly affected by this adverse effect. Therefore, the first few days after concrete pouring is the key period of maintenance, and more attention should be paid in construction.
Four, engineering construction technology experience
By attending the joint review of drawings, I learned the main contents of the joint review of drawings. Before the general project starts, the owner, design unit, contractor and quality supervision unit should all participate in the blue prints.the design, so as to find and solve the problems such as mistakes and contradictions in design, vague concepts in construction and possible difficulties in future construction, and avoid unnecessary losses in construction. The joint hearing should pay attention to the following points:
First, find out the defects and mistakes of the drawing itself. Review whether the drawing design conforms to the relevant national policies and regulations (architectural design, structural design, construction specifications, etc.). ); Whether the drawings and descriptions are clear and the reference standards are accurate; Whether there is any mistake or omission in the construction drawing standard; Whether the size, plane position and elevation of the general plan and the construction drawing are consistent, and whether the relationship between the plan, elevation and section is consistent; Whether the design of each professional post is coordinated.
Secondly, the feasibility of construction is combined with the characteristics of drawings to study whether the drawings can meet the requirements of drawings in terms of quality, safety, construction period, technology, material supply and even economic benefits, and suggest the design unit to make appropriate modifications when necessary.
Finally, whether the geological data are complete and can meet the requirements of the drawings; Whether the surrounding buildings or environment affect the construction of this building, etc. Whether the functional design of the construction drawing meets the requirements of the construction unit is the main content of the blue prints.the design.
Summarize drawings and other issues to prepare for joint examination, and the technical director of the project will convene relevant personnel to conduct internal preliminary examination. In order to better understand the designer's design principle, I consulted the relevant atlas, made an in-depth study of the drawings, raised many insightful questions, and had a heated discussion with the construction technicians, trying to figure out what I didn't understand. I found that the most important thing is that it doesn't conform to the atlas except the size and reinforcement of the structure, and I found that the doorway on the shear wall is also prone to mistakes.
The intense month of internship is over, and I still have a lot of gains this month. It is necessary to sum up after the internship. This internship made me deeply realize that reading is a way to increase my knowledge and broaden my horizons, but it is also an excellent choice to improve my comprehensive quality through more practice, being in the middle of practical things, touching the pulse of society and setting a position for myself.
This internship is to learn practical knowledge in this big school of society. This is also my first real contact and feeling with society. I firmly believe that through this period of internship, the practical experience gained will benefit me for life, and will be constantly verified in the actual work after graduation. I will continue to understand and appreciate what I have learned in my internship, and apply my theoretical knowledge and practical experience to my future practical work to fully demonstrate my personal value and life value. Strive to realize my ideal and bright future.

Production practice is an essential practical teaching link in the teaching plan of civil engineering specialty, and it is the unity of theoretical knowledge and engineering practice. During the internship, I went deep into the construction unit as a technician, took a high-rise residential area as an internship place, participated in the engineering construction work under the guidance of the director of the technical office of the project department, and successfully completed the six-week internship task. At the same time, it also lays a good foundation for the engineering time after graduation.
First, the internship content
(a) familiar with engineering construction management, technical management due to the short practice time, only participated in the specific operation of the construction process, now briefly summarized as follows:
1. The technical director of the project is responsible for implementing the technical post responsibility system and technical disclosure system. Technical disclosure must be made before each working procedure, and the "Technical Disclosure Record" should be filled in.
2. The project manager instructs all professional engineers to fill in the "Construction Log". The Engineering Manager shall record and keep a detailed "Construction Log". The contents of the "Construction Log" include the following aspects: the construction site of the day, the number of construction personnel at the site, the specific construction team, the specific person in charge at the site, the materials and equipment used in the construction, the operation method or technical disclosure, the climate of the day, the inspection and test of the construction site of the day, and the problems existing in the construction.
3, in the process of engineering construction, the technical office is responsible for the field labor deployment, schedule management, machinery use and construction safety, and keep relevant records. The project manager is responsible for presiding over the project meeting once a week, summarizing the progress of the project last week, finding out the gap between the actual progress of the project and the plan, and arranging the work this week. The chief engineer of the project summarized the construction quality last week and put forward suggestions and requirements for the next quality management.
4. In the process of construction, the system of self-inspection, mutual inspection, handover inspection and special inspection shall be implemented. The quality inspector of the construction team shall fill in the self-inspection form after passing the self-inspection of each working procedure, and the next working procedure can be started only after it is signed and approved by the relevant team leader. Unqualified processes must be reworked, and the next process can only be carried out after passing the acceptance again. By establishing the joint inspection system and filling in the quality joint inspection form, the quality of each sub-project will be strengthened. Concrete pouring application must be filled in before concrete construction.
5. Professional engineers are responsible for the design changes in the construction process, and timely communicate them to all business outlets and related construction teams according to the provisions of the "Contract Change Management" part of this quality plan.
6, concrete, mortar, waterproof materials by the operator is responsible for sampling, sent to the company's laboratory for testing, after passing the corresponding test report. Products can only be distributed after passing the test.
7. After the concealed works are inspected by the project quality inspector, the professional engineer shall fill in the concealed works acceptance record and report it to the owner or supervision engineer for acceptance. After the owner or supervision engineer signs the acceptance record, the construction can continue.
8. The monthly progress plan is compiled by the technical office, and the engineering manager is responsible for decomposing the monthly progress plan into every day of the week, and implementing dynamic monitoring and quantitative management to ensure the construction progress.
(B) the specific operation of construction technology
1. Compiling the construction technical disclosure and attending the technical disclosure meeting is the premise of the commencement of each sub-project/division project, and it is also a consistent technical guidance, which directly affects the quality of the project, and its reliability is very important. Therefore, as a technician, I must submit the disclosure to the director of the technical office for examination and approval before I can make disclosure to the captain of the construction team. During the internship, I specially wrote the technical disclosure of floor pipe hole plugging, underground garage foundation pit backfilling, air conditioning hole punching, fertilizer tank backfilling and so on. In this process, I searched a lot of information and benefited a lot.
2. When writing the technical disclosure of "floor pipe hole plugging", it mainly deals with engineering quality problems, which is rarely involved in class. Pipeline hole is a hole reserved for hydropower pipeline in the process of floor construction, and its aperture is larger than the radius of pipeline. If it is not sealed or not tightly sealed, it is very suitable for water leakage, so it needs technical treatment. Generally speaking, the pipe shaft is mainly chiseled into a figure of eight, as shown in the figure:-Then the formwork is installed (with wooden skin), sponge strips are attached to the joints between the formwork and the main structure and the pipe, and the formwork is required to be firmly installed and closely attached to the floor and pipe body, then the fine stone concrete is poured by stirring, inserted and tamped with steel bars, and finally the formwork is removed for maintenance.
3. For special circumstances, such as the reinforcement of the floor blocking the passage of the pipeline, it is necessary to fuse the reinforcement. During the technical treatment, the structural floor is chiseled or connected with the main body with expansion bolts (the hole is chiseled into a figure of eight), and the steel bar is welded by lap welding, with a welding length of 5d. The subsequent operation procedure is the same as the general situation. The preparation of the technical disclosure of Backfill of Foundation Pit in Underground Garage mainly uses the knowledge of "soil mechanics", such as checking the quality of backfill, sampling with circular knife method, measuring the organic content, dry density and moisture content of soil, and controlling the quality of soil by using the volume ratio of backfill to lime powder. When tamping, water can be properly sprayed to wet dry soil, but the phenomenon of "rubber soil" is strictly prohibited to ensure the bearing capacity and settlement of foundation.
Through the preparation of technical disclosure, I have a certain understanding of the construction technology of sub-projects/sub-projects, which not only consolidates the professional knowledge learned in class, but also familiarizes myself with relevant specifications, and also learns a lot of knowledge outside books.
Participate in the inspection and acceptance of engineering quality. During the construction process, the self-inspection, mutual inspection and handover inspection of the construction team shall be reported to the project department for review by the project quality inspector. Only after passing the inspection can the next working procedure be carried out. At the same time, I participated in the inspection and acceptance of engineering quality as a quality inspector. Be familiar with the construction drawings before going to the site, such as the reinforcement diagram of the wall, the reinforcement diagram of the floor beam and the template construction drawing. Template acceptance, mainly check whether the joint is tightly sealed, verticality is qualified, template installation is in line with the requirements of the room, etc. After the acceptance of reinforcement, check whether the protective layer thickness, stirrup spacing, stepped reinforcement, concealed column and concealed beam reinforcement meet the requirements; Plastering decoration is to check whether the napping strength and surface smoothness are qualified; Whether the waterproof layer is laid in accordance with the specifications, etc.
At the beginning, all I did was count the types, exact locations and quantities of engineering quality problems, such as honeycomb holes, slurry leakage, exposed tendons, expanded formwork, rotten roots and so on. By studying the technical disclosure of the repair scheme and actively consulting relevant technicians, I gradually mastered the methods to deal with these problems.
Repair scheme: Clean a small amount of small honeycomb, pits, leaking tendons and stones on the concrete surface with a wire brush, then clean them with water, then plaster them with 1: 2.5 cement mortar (mixed with building glue), and strengthen the maintenance work after the initial setting of plastering; When the honeycomb is serious or the reinforcement leakage is deep, remove the unconsolidated concrete and outstanding aggregate particles nearby, rinse them with clear water and fully wet them, then fill them with fine stone concrete with higher strength grade than the original concrete and carefully tamp them; For concrete structures with expansion, deformation and dislocation, drawing and cutting should be carried out according to the drawing size, and then roughening should be carried out according to the lines. Chiseling should be carried out with a sharp chisel first, and then carefully chisel with a flat chisel after chiseling is basically in place. Chiseled steel bars shall not be exposed or leveled.
Sorting out engineering data I sorted out a lot of engineering data during my internship, such as concrete pouring application, concealed engineering inspection records, engineering materials entry inspection sheet, materials and components entry inspection records, etc. Such as "concrete pouring application", the construction team passes the acceptance of the project department and the supervisor after the steel bars are bound, and the technical office of the project department specially sends personnel to declare the quantity and location of the required concrete to the concrete mixing station. Then, when the concrete transport vehicle comes into the site, it is required to submit the vehicle receipt. For example, if the concrete is self-inspected, the project department will fill in the pouring application and submit it to the supervisor for the record. Through the collation of these materials, I learned about the relevant procedures and norms of engineering construction.
Second, thinking and innovation.
There is no end to learning. Seeing the results, we should actively think about the causes of the problems and the ways to deal with them. Only in this way can we learn more knowledge in our work, truly achieve a good internship effect of integrating theory with practice, and enhance our ability to analyze and solve problems in the process of dealing with engineering and technical problems.
Many new technologies and materials have been adopted in the construction of this project. The main structure is full cast-in-place shear wall structure, and there are hidden columns and beams in the wall, which increases the room area and headroom. In decoration, such as kitchen and bathroom, lightweight ceramsite concrete partition board is used. Compared with the previous brick wall, this partition wall has the advantages of light weight, simple installation and reliable strength, which not only greatly reduces the load borne by the cast-in-place floor, but also speeds up the construction progress, shortens the construction period and saves the cost.
In the process of acceptance of constructional column reinforcement, the design unit chose smooth round reinforcement in the adoption of vertical reinforcement, but the friction between the stirrup bound by the construction team and the smooth round reinforcement was too small in the construction process, which led to the stirrup slipping and brought inconvenience to the construction. So the construction team changed the smooth round steel bar into threaded steel bar to increase friction and facilitate the binding construction of stirrups, but this change greatly increased the cost. Through positive thinking, I put forward the following rectification plan to the director of the technical office: the four vertical bars of the concealed column are made of two smooth round steel bars and two threaded steel bars, which are placed diagonally during construction, which not only increases the stability of stirrups, facilitates construction, but also reduces costs. The plan was affirmed by the director.
Third, summary.
After six weeks of production practice, I was deeply impressed. In terms of construction technology, the actual operation is based on theoretical knowledge, but it is more flexible and operable than theoretical knowledge. This requires learning professional knowledge, thinking actively and using it flexibly at work, so as to cultivate one's own thinking innovation and independent problem-solving ability. At the same time, I used this internship opportunity to get in touch with the society, got a good exercise, and made clear the direction I should develop in the remaining year of college life, especially the need to exercise my language communication and communication skills, study hard, work hard, and actively face every challenge.
