I write material for an essay about Expo , and some enter!

Mascot of the 2010 Shanghai World Expo.

Welcome to the Expo. The World Expo is the focus of the world's attention. At the Expo, you'll find a lot of things about technology, such as robots, cars, and more. Around us, you will also find that many people have a series of troubles because they do not understand technology.

What would our lives be like if we didn't have the technology involved? People will not dress as well as they do now; People don't build tall buildings ......On the other hand, if there is no technology to participate in our lives, then our lives will be as boring as in ancient times!

In the past, I always thought that scientific creation was just the business of those old experts, and it had nothing to do with us elementary school students. Ever since the school started the "Science and Technology Festival", I don't think so. It turns out that some people who have made great inventions have loved science since they were children and have made arduous efforts for the development of science and human civilization.

When Newton was in elementary school, he often made small machines and inventions, Gauss discovered the binomial theorem at the age of 11, and invented the method of making 17 sides with a compass and a ruler at the age of 18. Since ancient times, young people have produced talents. Science is not mysterious, science is all around us middle school students, and it depends on us thinking at every turn.

Now that the World Expo has opened, the focus of the country and even the world can be regarded as the World Expo, and the World Expo has opened at our doorstep, how can we not go to see it? The World Expo advocates a low-carbon life. You may say, how can low-carbon living be related to technology?

In fact, low-carbon living means that the energy consumed in daily life and rest should be reduced as much as possible, so as to reduce carbon dioxide emissions. In our lives, one of the objects that emit carbon dioxide from time to time is the vehicle that is often used - the car, why don't you say that low-carbon life is related to life?

Therefore, we must love science from an early age, pay attention to civilization, study hard, strive to improve our ideological and moral quality and scientific and cultural quality, constantly improve our ability to practice science and innovate ability, and be a person with scientific creativity to serve the motherland.

In my eyes, the Expo is huge and the ceremony is grand. I can imagine that in Shanghai, people who have no borders and are far from all over the world are discussing the changes here, not only the environment has become more hygienic, but the construction has also become better and better. After the Olympic Games, it is the second event that the people of the motherland are excited about.

In terms of construction, the construction of the Shanghai World Expo Park is still under careful planning, and it is estimated that it will be a permanent exhibition hall. My favorite is the expo's mascot, Hypertherm. It's an aqua blue and energetic little elf.

The image of Hypertherm welcomes friends from all over the world with warm arms and a confident smile. Hypertherm is based on the Chinese character for "human" as the core idea, because only people from all over the world support each other, people and nature. People and society.

When people live in harmony with each other, such a city will be better.

I am looking forward to the World Expo to be held in Shanghai, Shanghai has been making continuous progress, and the people of the motherland are also very involved in the World Expo. Olympic. I believe that the World Expo will be a complete success like the Olympic Games, becoming a realm that is difficult for other countries to replace, and winning glory for the whole of China!

I hope I can also do my part for the Expo and cheer for the coming of the Expo!
