The moon is the earth"s largest and only natural satellite. A satellite is a small body that goes around a planet. The first man-made satellite went into the orbit in 1957. By 1968 there were over three hundred satellites in the orbit. Some satellites send back weather pictures. Others send out radio waves. Some satellites are what we call "junk". In 1963, the United States put millions of small pieces of wire into orbit. They were used to carry radio waves. Many of these wires may still be there. Some space junk was not put in the orbit. For example, one piece of space junk is a glove lost by an astronaut! Space is very big. Does it matter if there is junk in the orbit? Many scientists think so. They say we must pay much attention to how we use this new resource. They think anything man puts into space should be made to come back to earth when its work is done. They say it"s dangerous to have space junk, because it"s possible for spacecraft to collide with the junk. |

Have you ever noticed an advertisement which says "Learn a foreign language in six weeks, or your money back! From the first day your pronunciation will be excellent. Just send…" and so on? Of course, it never happens quite like that. The only language that is easy to learn is the mother tongue. And think how much practice that gets! Before the Second World War people usually learned a foreign language in order to read the literature (文学) of the country. Now speaking the foreign language is what most people want. Every year many millions of people start learning one. How do they do it? Some people try at home, with books and tapes; some use radio or television programmes; others go to evening classes. If they use the language only two or three times a week, learning it will take a long time, like language learning at school. A few people try to learn a language fast by studying for six or more hours a day. It is clearly easier to learn the language in the country where it is spoken. However, most people cannot afford this, and for many it is not necessary. They need the language in order to do their work better. For example, scientists and doctors mainly need to be able to read books and reports in the foreign language. Whether the language is learned quickly or slowly, it is hard work. Machines and good books will help, but they cannot do the students work for him. |

A. more than two month B. half a year C. six months D. less than two month |
2. Before the Second World War people learned a foreign language in order to ______. |

Different weather makes people feel different. It influences health, intelligence (智力) and feelings. In August, it is very hot and wet in the southern part of the United States. People there have heart trouble and other kinds of health problems during this month. In the northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March. The weather can also influence intelligence. For example, in a 1983 report by scientists that IQ of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year (July and August). Weather also has a strong influence on people"s feelings. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel unhappy during cold weather. But fat people may have a hard time in hot summer. At about 18℃, people become stronger. Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops on low pressure days. There is "good weather" for work and health. People feel best at a temperature of about 18℃. Are you feeling sad, tired, forgetful, or unhappy today? It may be the weather"s problem. |
1. ______ can have a bad influence on health. |
[ ] |
A. Hot weather B. Good weather C. Warm weather D. High intelligence |
2. People may have more intelligence when ______ comes. |
