I also saw a robot with sensors (感应器) in all parts of its body. With the help of 5G technology, the robot can do the same things as people do.I hope I can create something like 5G. Liu Yu,13 Chenguang High School, Beijing People love to travel. In the 1970s, anyone who was lucky enough to have a bicycle would be the envy (羡慕的对象) of others. Then, green trains came out. But they ran at a speed of 30 km per hour. In the 2010s, the speed of China's fastest trains had risen to 350 km per hour. For my mom, she had her first train trip when she was 17.

As I didn't need to pay anything for it, I ordered one. When I received the watch, I couldn't believe how nice it looked. It looked better than any other thing I owned. Suddenly I wanted to buy some clothes to match my watch. Before buying clothes I did a little reading to find out how to dress better. Over the next few weeks, I began to pay attention to my appearance. When I began to dress a little nicer, I felt better than before. I liked that feeling and began taking better care of myself. These little changes began to make big differences. Two months ago, I began to exercise. And I started with some simple sit-ups and jumping jacks (开合跳) at home. One month ago I bought my first gym membership(会员). I was a little hesitant(迟疑的) at first, but then I began to enjoy it more and more.I visit the gym three times a week now! I've changed my health habits, my appearance and my life style. I'm not a slob anymore. Even the smallest thing can serve as a good beginning.

B Over the last few centuries, there have been many changes in our lives. To start with, people were not able to travel such a long distance in such a short time in the past. Planes were not very popular at that time because they used to be a very expensive way to travel. Nowadays, more and more people can travel by plane and we can take many other fast and comfortable vehicles, such as cars and high-speed trains. Secondly, in the past, people had to work much harder because they did not have the tools we have today. Today, most of the difficult and dangerous work is done by computers and machines. Thirdly, in the past, the living conditions were not as good as they are now. There were no bathrooms or running water in many houses, and many people could not buy things like refrigerators, TV sets or washing machines. Now, most families have several of these things. Lastly, communication has become much easier than before. In the past, we kept in touch with others by writing letters or sending faxes, but now we have many other ways to choose from, such as making a phone call, sending emails or messages and chatting online.Moreover, we can even see the people whom we are making a phone call with through mobile phones, and we can see each other while chatting online. The most surprising thing is that we can make a phone call with the astronauts and see them when they are in space.What a magical thing! Thanks to the technology, especially the Internet, our lives have become much easier and happier than before. I'm sure they will become more wonderful in the future. Don't you think so? 根据材料内容选择最佳答案。 ( )51. Why were planes not so popular many years ago? A.Because they were not big enough. B. Because they were not able to fly long. C. Because they were very expensive. D. Because they were not fast enough. ( )52. In the past, people worked A.for fewer hours B. much harder C. more easily D. more quickly ( )53. What does the fourth paragraph mainly tell us? A. Many families have TV sets and washing machines nowadays. B. There were no bathrooms or running water before. C.

There are many tall buildings and you can see wide roads everywhere.There are many buses past our community every day. And many people have bought their own cars, so it's easy to travel around.
