There is no doubt that Tsinghua's water conservancy ranks first in the country. There are many academicians in the Department of Water Conservancy, and there have also been national leaders and leaders from all walks of life. Therefore, choosing Tsinghua University Water Conservancy Postgraduate Entrance Examination is undoubtedly a way to prove yourself, break through yourself and realize the value of life. However, this road is also risky. In recent years, the Water Conservancy Department of Tsinghua has kept the habit of recruiting four people. According to1/21,the four places are divided into three directions: civil engineering direction, water conservancy direction and project management direction. Among them, the direction of hydraulic engineering is divided into hydrology, hydraulics and hydraulic structure. In the past 20 years, the specialized courses of water conservancy engineering in Tsinghua University have experienced a wave of reform. Combining watershed hydrology, engineering fluid mechanics and structural mechanics in previous years into the unified foundation of hydraulic engineering greatly improves the review task of professional courses. The following will introduce specific review suggestions. However, it is not impossible to get into Tsinghua. As long as the goal is determined, a reasonable review plan is made, and the review is carried out in a down-to-earth manner, there is no problem in the normal play in the examination room.
Two? Review planning of public courses.
1, mathematics
Mathematics review is generally the earliest, and many people often start reviewing in their junior year. If you use books, the lecture given by Zhang Yu 18 or Li Yongle Review Book, I first gave a lecture on 18, but later I bought and wrote a review book (in fact, this is the case. If you see a classmate writing both books, you will naturally panic and finally have to buy and write). Of course, the review of junior year will often be interrupted by final exams and class settings. Then when the summer vacation starts again, it will start all over again. But this is definitely not to say that your previous review was in vain. After studying it again, it must feel different. If you study, you usually watch videos of Zhang Yu or Tang Jiafeng, and also watch videos of Li Yongle or other teachers. I have seen many Tang Jiafeng, and Ms. Zhang has also seen some. It's my choice. So for me, the bottom line of the summer vacation goal is to watch the basic course video, watch 18 lessons, and then try to write 1000 questions, 660. After all, math problems are never limited to doing more. There is nothing to say after school starts, but all kinds of brush questions. It can be said that if you open a treasure and enter the postgraduate entrance examination for mathematics, you will know what you want to do. When 1 1 or so, all kinds of simulation questions come out, then brush the paper and brush the real questions.
2. English
From the examination point of view, English for postgraduate entrance examination, like politics, is a subject that can't spend too much time trying to get high marks. Because the time allocation of review should be arranged in strict accordance with the subject scores. Therefore, the advice to English is the same as the advice to politics, provided that the subjects with a score of 150 are well reviewed, and then the high score of English is considered. On the contrary, English should aim at crossing the line.
Question types and scores: cloze 10, reading 40, new question type 10, translation 10, short composition 10, large composition 20. Target scores can be set according to major topics, such as: target 60: full score 4, reading 28, new topic 6, translation 4, composition 18. (Take English One as an example) Take this as the goal of usual training.
Words: Words must be mastered. After reading this article, if there is still about 6 months before the initial test, I strongly recommend watching Zhu Wei's video "Practicing Love with Words". Combine the word book and firmly grasp the words!
If the time is short, such as within 5 months, then focus on the real words. Be sure to know 95% of the words you read, and it is best to be familiar with memory.
You can also remember the scene, look directly at the unknown words in the article, what does this word mean in this article, take an expensive notebook (so you will feel distressed and have to go back to find it if you lose it), and slowly overcome these words.
Reading: Do the real questions at least twice, and the translation can recite the real questions around 10. Do the real questions repeatedly, compare the different options, and cultivate your own ideas.
Inspection section:
The first step is to answer the questions immediately and learn to grade yourself. The second step is to write down the reasons for all the wrong options in each topic after the options, or mark them in the corresponding position in the text. And if you do something wrong, you should also analyze why you did it wrong and write it down in a separate notebook. The third step is to copy all the words you don't know in the article into a single word book and take them out every day.
New questions: The new English questions are relatively simple and can be read according to conventional thinking. Focus on speaking English. First, don't read the full text. First, there is not enough time. Second, personal experience shows that you really can't read. The reading difficulty and length of the new questions are higher than that of ordinary reading. The core of its investigation lies in the coherence of paragraphs.
Therefore, learning a few skills, such as "agreeing to reproduce", "referring to pronouns" and "conjunction cohesion", is enough to infer the answer from the last sentence of the first sentence and the sentences before and after the space.
Gestalt and translation: each 10, chicken ribs. Gestalt depends on foundation and luck. If you invest for five months, it may not be able to increase by three points steadily, and the cost performance is relatively low. Translation in the usual reading process, we should constantly translate articles without separate training. Therefore, this part of time can be appropriately compressed, saving time to study mathematics and specialized courses.
Composition: Combining with He's composition book, classify the composition types of real questions. Roughly 4-6 categories, change the sentence and form your own template. Then the real questions are put into training, and the subject words can be written in the examination room. Practice two short compositions and one big composition every week according to the real questions, and pay attention to learning to classify topics, such as education, network, environmental protection and old-age care. These are indeed repetitive. Write two articles under each topic. At this stage, you should still practice at least one set of real questions every week, and try to practice those questions that you didn't do very well last month.
It is important to note here that writing does not mean that the higher the vocabulary, the higher the score. Many English words are contextualized, which means the same thing when translated into Chinese, but in authentic English expressions, they are really not used in this way, and the marking teachers are also very skilled. If you want to get high marks, you should write as many specific contents as possible, and don't blindly use cliches to make up the number of words. When you write a composition, you need to remember it. Then write it silently on the answer sheet, and pay attention to controlling the time. The big composition 15 minutes, and the small composition will be finished in 5 minutes. Pay attention to practicing calligraphy!
3. Politics
Most people didn't formally start reviewing until the third year of high school started. Holding Xiao Xiurong's book, watching Xu Tao's video. After 1 1 month, especially in1February, political status surged and short answers were needed. This will take up a lot of time and energy. I can only give you one opinion: trust Xiao Xiurong unconditionally, and uncle will always be your uncle.
Three? Review plan and preliminary examination content of specialized courses
Because it was during the summer vacation that I was informed of the reform of specialized courses in Tsinghua, the task was tripled at once, so most of the subsequent time was assigned to specialized courses, and time became tense, which led to the original plan of restoring other disciplines being disrupted. The books on hydraulics and hydrology in specialized courses should be read three times as much as possible, while structural mechanics pays more attention to calculation, so reading once is enough. I suggest that the earlier the review of specialized courses, the better. You can start reading this book for the first time next semester. The earlier you review, the more fully you use your time, the better your results will be. The following specific topics were introduced:
Structural mechanics:
The reference materials are Long Yuqiu, Bao Shihua and Yuan Yi (20 12), Basic Course of Structural Mechanics (3rd edition), Higher Education Press. The inspection contents are as follows
1, geometric composition analysis of plane system; Basic concepts of geometric structure analysis and calculation of degrees of freedom of plane system
2. Calculation and analysis of internal force and displacement of statically indeterminate structure: calculation of internal force and displacement of statically determinate beam, statically determinate rigid frame, statically determinate arch, statically determinate truss and statically determinate composite structure; Force analysis and displacement calculation of statically indeterminate structure are carried out by using virtual work principle; Calculation of structural displacement caused by load, temperature and bearing movement.
3. Calculation and analysis of internal force and displacement of statically indeterminate structure: basic principles of force method and displacement method; Force method and displacement method for statically indeterminate structures: the basic principles and calculation methods of asymptotic method and matrix displacement method; Comparison and reasonable application of various solutions for statically indeterminate structures:
4. Basic principles and methods of structural dynamic calculation: free vibration with single degree of freedom and undamped forced vibration; Free vibration and forced vibration of two-degree-of-freedom system under harmonic load.
After reading the book before review, you can buy a set of problem sets of structural mechanics in Yu Lingling and do the test center part more than twice from beginning to end. It is relatively easy for the Department of Water Conservancy to take the postgraduate entrance examination for structural mechanics, so it should be no problem to make this problem set thorough.
Hydrology:
Reference materials are Yang Dawen, Yang Hanbo and Lei Huimin (20 14), Watershed Hydrology, Tsinghua University Publishing House. The inspection contents are as follows
1, distribution and circulation of water on the earth; Distribution and circulation of water on the earth, global energy balance, basin water cycle and water balance
2. Basic characteristics of precipitation atmosphere, formation and classification of precipitation, weather system affecting precipitation, precipitation observation and analysis of precipitation characteristics in river basins.
3. Physical process, evaporation capacity and actual evaporation capacity of evaporation in the basin.
4. Rainfall infiltration and soil moisture movement, rainfall infiltration, soil moisture movement process, adjustment and storage of soil vadose zone, recharge and discharge of groundwater.
5. River Runoff Formation of River Runoff, Measurement of River Runoff, Geomorphology and River Network Structure of River Basin, Measurement of River Runoff
6. Analysis of watershed runoff yield, mechanism of watershed runoff yield, calculation of watershed runoff yield and calculation of watershed runoff yield
7, watershed hydrological model and hydrological forecast hydrological forecast classification, short-term flood forecast, long-term runoff forecast.
8. Hydrological statistical analysis methods Hydrological time series and its statistical characteristics, probability distribution commonly used in hydrology, statistical parameter estimation of time series, and hydrological correlation analysis.
9. Design annual runoff; Calculate the designed annual runoff according to the long-term measured data, and calculate the designed annual runoff according to the short-term measured data.
10, design flood; Three elements of design flood: design flood deduced from discharge data, design flood deduced from rainstorm data, possible maximum rainstorm and possible maximum flood.
Hydrology requires skilled memory except the calculation in the later chapters, so it is not an exaggeration to read the whole book three times. Many detailed knowledge points in the book have to be memorized. You can't say that you can't think of or be sure of the answer when you see the familiar questions in the exam. When I review, I will pick out the key notes, which is of great benefit to memory and subsequent review and consolidation.
Engineering fluid mechanics;
The reference materials are Li Yuzhu and He Wuzhou (2006), the first volume of Engineering Fluid Mechanics published by Tsinghua University Press. The inspection contents are as follows
1, physical and mechanical properties of fluid, compressibility, viscosity and surface tension characteristics of fluid.
2. Hydrostatics: hydrostatic pressure, the equilibrium differential equation of static fluid, the distribution of hydrostatic pressure in gravity field, the principle of pressure measurement, the relative balance between action and total liquid pressure and the upper surface of an object.
3. Description method of fluid motion, follow-up derivative, motion analysis of fluid micelle and velocity decomposition theorem.
4. Continuity equation, Euler equation and NS equation of basic fluid motion in fluid dynamics.
5. Characteristics, continuity equation, Bernoulli equation and momentum equation of one-dimensional steady flow and gradual flow.
6. Flow resistance and energy loss, flow pattern, head loss along the way, local head loss, hydraulic calculation of simple pipelines and complex pipelines.
7. Similarity theory, dimensional coordination principle, dimensional analysis, dimensionless number and similarity principle are relatively easy to learn. Just master the after-school exercises in each chapter. In addition, we should focus on the application conditions and derivation of the formula. Tsinghua is interested in the theoretical part of specialized courses.
Four? Second interview situation
This is not urgent. It is king to do well in the initial exam first. Generally, the supplementary record of water conservancy in Tsinghua is 1.5: 1. The content of the survey is very extensive and random. The average teacher takes your report card and resume and asks wherever he wants. The emphasis is also very casual, some will focus on internship experience, undergraduate projects, some will focus on professional courses in this science and so on. In short, students' personal qualities and abilities will be comprehensively examined. In previous years, the written test will examine English-Chinese translation, focusing on some professional basic vocabulary. This year, due to the epidemic situation, this part will be cancelled and graded according to personal self-report.
Five? chicken soup; inspirational nonsense
The basic preparation plan has been written. Here are some strategic suggestions. I hope everyone who takes the postgraduate entrance examination can regard it as a springboard rather than an end, and think clearly about the real purpose of his postgraduate entrance examination, so that you can face the postgraduate entrance examination and life after it with a more peaceful attitude. In addition, it is always the most difficult to take the first step of preparing for the exam. Don't doubt your true ability. Every effort you make is to increase your chances of getting into the exam. Then, some people say that they may have some shortcomings, so please be sure to make it clear whether it will hinder your postgraduate entrance examination or just give you an excuse to avoid your efforts. If your college life is mediocre, the postgraduate entrance examination will formally give you an excellent opportunity to break through yourself. Mediocre college life is just a thing of the past, and the inertia formed by this life is your stumbling block. Besides, don't let your classmates play with you. As an adult, please learn to have basic self-control and be responsible for your actions. Please get into the habit. Seeing everyone playing will make you more motivated to learn this valuable skill. Finally, I hope everyone's dream will come true, Tsinghua campus.
