| 第2、3、4、5题：Because we can feel that things are heavy, we think of weight as being a fixed quality in an object, but it is not really fixed at all. If you could take a onepound packet of butter 4, 000 miles out from the earth, it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4 000 miles out into space? The reson is this: All objects have a natural attraction for all other objects; this is called gravitational attraction, but this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4 000 miles from the centre (in other words the radius(半径)of the earth is 4 000 miles). When we took the butter 4 000 miles out, it was 8 000 miles from the centre, which is twice the distance. If you double the distance between two objects, their gravitational attraction decreases(减少)two times two. If you treble(翻三倍)the distance, it gets nine times weaker(three times three). If you take it four times as far away, it gets sixteen times weaker(four times four)and so on. 69. The best title for this passage is. A、The Earth Weight B、Weight in Space C、Changing Weight on the Earth D、Weight on and off the Earth 70. We can feel things are heavy because. A、weight is a fixed quality in an object B、they are far away from the centre of the earth C、of the earth's strong attraction for them D、they are not taken away from the surface of the earth 71. If the distance between two objects is shortened by half, their gravitational attraction will. A、double B、become four times stronger C、be the same D、get four times weaker 72. If an object weighed one pound 8 000 miles above the earth, it would weighon the surface of the earth. A、6 pounds B、4 pounds C、9 pounds D、1/9 pound |

| 第6、7、8、9题：Hotlines have become common in China. Some radio broadcasting stations use hotlines to encourage the listeners to take part in the talk shows. That's a good idea. Yet, the fact is, some people do nothing but break the whole programme. Some people know little about the topic under discussion. Sometimes they do not even know what the host(主持人)is talking about. So the host has to tell the caller what the show is about .Usually the caller will ask a few questions which express his hope and show his ignorance(无知).Then the host has to answer and explain-how silly this is !It wastes a lot of time . It seems that some people phone the hotlines in fun. They just want to let the listeners hear them. They don't care what the topic is , whether they themselves are interested in or how silly they appear to be. I'm totally bored(厌烦)by those people . It's necessary for radio stations to improve the hotline programmes. In my opinion, if a caller doesn't know what is going on, the operator should not let the caller take part in it. 52. The sentence, "Some people do nothing but break the whole programme." may tell us that ______. A. radio stations use hotlines in a wrong way B. it is a fact C. it is a good idea D. some people have unclear thoughts 53. The host has to answer and explain, ____ . A. for the host works hard B. because of the caller's ignorance C. for the host likes talking to the caller D. because of a lot of questions raised by the caller 54. The passage doesn't tell us the idea ________ . A. that some listeners phone the hotlines in fun B. that some people just want to be heard by others C. that some people who don't care what the topic is must have realized that they appear to be silly D. what the hotline programmes are 55. Which of the following is not true? A. Some people know little about the topic under discussion. B. Some people do not know what the host is talking about C. Some people do not know what the show is about D. The writer tells us that the host is silly. |
