As space science develops, man has learned more and more about space. Space is not only amazing but also dangerous. While working in space, spacemen are facing danger as well as success.
Scientists have found out that radiation(辐射) is the greatest danger to spacemen in space. When spacemen are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage(危害) done by radiation won't be discovered until their children or even grandchildren are born. Some special medicine may work a little, but no really helpful medicine has been.
Space junk is also thought a great danger to spacemen. It's reported that there are 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space junk. An explosion(爆炸) in 1996 made a cloud of 300,000.fragments, each at least 4mm in size, and even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and reporting any possible danger all the time. They are working on helpful ways to do with space junk.
Although space is really dangerous, it interests everyone on the earth. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space in a few years. So we should care for space and do something to help improve the space environment.__________ shows the man-made things in space in the correct way.

It is a very common thing for a person to have a good friend. My good friend is Diana. She is a rich and proud girl. She often thinks that she is too good for anyone, so nobody wants to be her friend.

Why do we need to throw less away? There are two reasons. One is that some resources (资源) are nonrenewable (不可再生的) That means there is only a certain amount of that resource in the world . One example of this is oil. When we use up all the oil in the world, there will be no more.
There is another reason for throwing less away. All of our trash has to be put somewhere. Often , it is put into garbage dumps (垃圾场). Much of that trash will be there for hundreds of years. The dumps will be filled up with all this trash.
