Space rubbish is also thought to be a great danger to spacemen. It’s reported that there were 9,000 man-made things flying in space. About 30% of these are satellites, 10% are spaceships, and the rest are space rubbish. An explosion(爆炸)in space in 1999 made a cloud of 300,000 fragments, each at least 4mm in size. A small piece of these even knocked a spaceship window and caused some damage(损坏).
Scientists are watching and reporting any possible danger all the time. They are working to deal with space rubbish. Although space is really dangerous, it interests many people on the earth. In the near future, it may become possible 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 do something to help improve the space environment.

Close contacts between Japan and the rest of the world were created in the twentieth century. In the last forty years, business contacts between Japan and the West have become very important. Many foreign companies now have offices in Japan and Japanese businessmen do business around the world. Differences between Japanese and Western ways of doing business, however, often bewilder foreign businessmen and make doing business in Japan difficult for foreigners.
The American businessman, for example, wants to start talking business immediately. He does not want to wait. The Japanese businessman, on the other hand, likes to arrive at decisions after giving them serious thought. Another thing foreign businessmen have difficulty in understanding is when a Japanese means “Yes” or “No”. This is because of cultural differences between Japanese and Western society(社会), Which make it difficult for a Japanese to say “No” directly.
In the USA, it is easy to say “No” to something one does not want to do. But in Japan, it is very difficult to say “No”. To refuse an invitation or a request(请求) with “No” is felt to be impolite. It is thought to be selfish and unfriendly. So instead of saying “No” directly, the Japanese have developed many ways to avoid(避免) saying “No”. These can help them avoid hurting other people’s feelings. However, this often makes their ways of doing business rather difficult for foreigners to understand and follow.What often makes foreigners feel difficult to do business in Japan?
A.Their different ways of doing business. |
B.Their different lifestyles. |
C.The fact that the Japanese never say “No”. |
D.The fact that the Japanese are slow to take action. |

A.American businessmen do things more slowly than Japanese ones. |
B.American businessmen like to say “Yes” and “No”. |
C.Americans usually say what they are thinking. |
D.Americans do not say what they think or feel clearly. |

A.Japanese businessmen are good at business |
B.foreign businessmen should try to know Japanese ways of doing business |
C.foreign businessmen must be more polite |
D.you must learn from Japanese businessmen if you want to succeed |
America is a mobile society. Friendships between Americans can be close and real, yet disappear soon. They don’t feel hurt.
