What’s a big problem in Shenzhen today, do you think? Besides pollution, traffic is, of course.

There are too many people, too many cars but too little space so the roads are always busy. You can almost see traffic jams everywhere. It is even worse when everyone is going to school or to work. What’s more, cars need fuel(燃料) to move, so they let out a lot of dirty smoke and pollute the air.

However, the government is trying many ways to solve the problem. We can see more roads and footbridges over the main streets. And the workers are making some roads wider. It is said every car will have a computer. The computer can study the latest traffic news. Then it will look over its own map for the best way to drive and they won’t get into traffic jams.

Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（國際太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.
In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(陰暗處)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.
Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !
Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.
