Technology is everywhere, and technology makes human beings extremely proud!
How important technology is to us, if one day, without electricity, people will continue to live in darkness; Without gas and oil, wouldn't people want to eat raw things or drill wood to make a fire and continue to pull carts with raw animals? Without mobile phones and computers, do people still use flying pigeons to pass books?
From this perspective, we can't live without the contribution of science and technology all the time. I believe that everyone around us is constantly exploring in their own way and making contributions to the development of science and technology. Although I was naughty, I really experienced the taste of technology: I put some baking soda in the quilt and then added white vinegar, and then the volcano erupted! Suddenly, white vinegar emerged.
With the rapid development of science and technology, science not only serves the cutting-edge technology, but also penetrates into our daily life more and more, which requires us to love and learn science in our youth. I participated in the provincial science and technology innovation and invention competition and won the second prize. He also participated in the municipal science and technology innovation and invention competition and won the third prize. These achievements are inseparable from the hard work of teachers. Participating in science and technology competitions and reading science and technology books have made me understand a lot. Precise robots, cars without fuel, virtual football matches, high-tech information transmission, and so on, vivid and interesting phenomena have aroused my desire to explore science more and more.
Each of us should study science, spread civilization and create a new life while enjoying life. Nowadays, the technology products are updated faster and faster, and video TV, computer surfing and pacemakers are not new. From the vacuum cleaner invented by 190 1 to artificial earth satellites and manned spacecraft, science and technology have shown great power in different fields. With the popularization of electronic industry and communication technology, and the wide application of nanotechnology and superconducting materials, bioengineered foods such as space green peppers and artificial steaks will appear on your table in the near future. Studying science and technology is not only to become a scientist and adapt to life, but more importantly, to become the master of the new century, to undertake the new century and to make contributions to national construction and human civilization.

2 1 century, people can see the development and innovation of science and technology everywhere. In the near future, people can travel in space by spaceship, make video calls or chat directly with their mobile phones or computers without writing letters. You don't have to cook, just use an electric rice cooker. After half an hour, delicious white rice can be presented on our dining table. Following China's "Shenzhou-9" expedition to space and successfully docked with Tiangong-1, Shenzhou-10 was successfully launched at 5: 38 pm on June 1 1 2065438, and docked with Tiangong-1 again. Success again and again marks a country's technological development in the space field, adding a brilliant stroke to China's past space career.
Just yesterday, it was an exciting day. At 5: 38, with the countdown of scientific and technological personnel, the fire was ignited. A few seconds later, Shenzhou-10 rose to the sky with cheers from all corners of the country. I believe that at this moment, all people in China are happy and proud of China's space career.
Moreover, more than a month ago, our school also organized a model airplane production competition for young people's scientific and technological works. I also signed up for the competition. I think this is to show my scientific and technological ability and operate it by myself, so that we can have a strong interest in science and technology and study it.
So I signed up with my classmates, and my aerial photos began to be assembled. I'll assemble the hull first, tear off those signs and stick them on the model airplane, one by one, then cover the flags and assemble the parts. I tied three wires to the motor according to the instructions, red wire, yellow wire and black wire, and then tied the red wire and yellow wire to the switch. After tightening the motor and screws, put them on the seat, and then fix the motor with screws. Finally, I installed the battery, turned on the switch, and the motor began to turn. Finally, I put the upper and lower covers together.
Finally, on Tuesday, we have a model plane competition. Look at those people's model planes swimming in the water, they all deviated from the direction and got a few points. I thought to myself, "There are only two people out of ten, and my strength is not strong. It is not easy for me to get high marks. "
Finally, it was my turn. I squatted down and felt very nervous. My palms are sweating. Under the teacher's rhythmic "preparation", I turned on the switch of the model airplane and put it in the water. When the teacher said to start, I released my hand and let the model airplane go forward by itself. At first, the model plane was in the middle, but when it reached two thirds, it suddenly deviated from the channel and finally got 40 points.
This competition made me learn a lot of scientific knowledge, deepened my love for science and technology, and made me understand that only hands-on operation is practical.
Our country is gradually moving towards prosperity, and our science and technology are also gradually developing. Although our country can't compare with western developed countries. But I believe that as long as each of us realizes his dream, our country will become stronger.
