It is 40 meters long and 6 meters wide. This must be the biggest bus you have ever seen. It can carry 1,200 to 1,400 people.

It is China's new Super Bus. It is going for a test run in Beijing at the end of this year. Some other cities are also interested in running the Super Bus. They hope it can solve traffic problems.

    The Super Bus runs along fixed tracks (固定轨道). The bus sits on top of two 2.2-meter-tall legs. The legs have wheels at one end. Small cars can drive under the bus, so the Super Bus does not take up road space.

The bus runs on electricity and solar power. It can travel up to 60 km every hour. Its creator, Song Youzhou, says it can reduce a lot of traffic jams (堵塞).

    The Super Bus can do the work of 40 buses. In that way, it can save 860 tons of fuel (燃料) every year, according to Song.

    "To build a Super Bus and its track costs less than building subways. Subways are nearly ten times more expensive to build." Song said.

    Some people worry that the Super Bus may not be safe. However, Song says there's no need for concern. The Super Bus has laser scanners (激光扫描仪) between its legs. The scanners make sure the cars keep a safe distance.

    In most parts of the world, many students help their schools make less pollution．They join environment clubs．In an environment club, people work together to make our environment clean．

    Here are some things students often do．

    No-garbage lunches．How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again．Every week they will choose the classes that make the least garbage and report them to the whole school．

    No-car day．On a no-car day, nobody comes to school in a car including the students and the teachers．Cars give pollution to us, so remember:

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic meters of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend those broken toilets．

    We love our environment．Let's work together to make it better．

    On April 2, we said goodbye to Tiangong I, China's first space lab. According to the China Manned Space Agency (中国载人航天), Tiangong I re-entered the Earth's atmosphere (大气层) and some of its debris (碎片) fell into the South Pacific Ocean.

    There are many spacecraft (宇宙飞船) that are still in orbit(轨道) above the Earth. After finishing their trips, they will all re-enter the Earth's atmosphere like Tiangong I.

    There are two types of re-entries: controlled re-entry and uncontrolled re-entry.

    Some satellites and manned spacecraft come back to the Earth in a controlled re-entry. Experts calculate (计算) the path of the falling spacecraft and its speed. Thy can guide the spacecraft to fall in a chosen area.

    Some spacecraft may have problems while in space after a certain amount of time. These spacecraft come back in an uncontrolled re-entry. It is hard to tell when and where these spacecraft will fall until the last few hours. The US space station Skylab came back partially uncontrolled in 1979. Parts of the station fell in western Australia, but no one was hurt.

    During re-entry, most of the spacecraft will burn up while passing through the Earth's atmosphere. Only a small amount of the debris will reach the ground. The debris typically ends up falling into the ocean, China Daily reported.

    I am a Chinese middle school student. I am 1 . I am in Class Three Grade Seven. I go to school by 2 every day.

    I live in Beijing. There are four people in my 3 . They are my father, my mother, my 4 and I. My father is a manager and my mother is a secretary in 5 office. My sister and I are 6 school.

    There are some 7 in my city. And there are many trees in front of 8 buildings. There is a garden 9 my house. There are many flowers in it. I like them very much. There is a playground near my home. I often 10 football in it.

    Not many years ago, a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was 75, he gave ￡12,000 to the village school to buy land and equipment for a children's playground.

As a result of his kindness, many people came to visit him. Among them was a newspaperman. During their talk, Johnson remarked that he was 75 and expected to live to be 100, and the newspaperman asked him how he managed to be healthy at 75. Johnson had a sense of humor. He liked whisky and drank some each day. "I have an injection (注射) in my neck each evening", he told the newspaperman, thinking of his evening glass of whisky.

The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was 75 and had a daily injection in his neck. Within a week, Johnson received thousands of letters from all over Britain, asking him for the secret of his daily injection.

I was walking along a busy road when I noticed a young man standing near the crossing selling toys.1I would hurry past such sellers. But I found this young man was 2, so I stood for some time without crossing the street. I wanted to see how he sold his things.

Soon, a young mother with a little girl came by and the child set 3 eyes on one of the teddy bears. The mother asked the 4 and it was only one dollar. She 5 out a 10­dollar note from her handbag and told the young man that she was giving him 10 dollars and wanted the 6 back. I was wondering how he was going to do it. He told the young mother to put the money in the bag 7 around his neck and take out her change.

I realized that this young man depended on believing people would not cheat him. There was no way for him to know 8 someone took out more than they should have done. I was so 9. I bought a car model from him that I did not need. As I walked down the street, I gave the car model to a kid walking with his father.

I kept thinking that the world would be a better place if we could all learn to 10others more, like the young blind street seller.
