| 第1、2、3、4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7、8、9、10、11题：A Stage plays, at first, seem a lot like films. Both use actors and dialogue and scenery. But if you try to make a film by setting up a camera in front of the stage, you will find it won’t work. A film made in this way will leave the audience cold. And even worse you’ll b3e wasting a powerful tool --- the camera. A stage is actually a box. One side of the box has been removed so the audience can see what’s going on inside. The actors remain at a fixed audience. In the film, however, the camera can bring the audience up close and fix their attention on small but important things: a frightened look, a whisper, a trembling of hands. The camera offers the film maker freedom allowing him to move easily across barriers(界限) of time and space. He can show his action in real cities and on real farms. He can also use the camera to change the scene dozens of times in one film. No expert of the stage can do this. 36. The main idea of the text is that ________ . A. stage plays and films are two different kinds of art B. it is always disappointing to turn play into films C. films have certain advantages(长处) over stage plays D. the camera has made film making easy and possible 37. What is wrong with making a film by setting up a camera before the stage ? A. Fewer and fewer people will go to the theatre. B. The audience cannot see what is going on on the stage. C. The scene cannot be changed from time to time. D. The powerful camera cannot be made good use of. 38. Which of the following can show that the camera is a powerful tool ? A. It can move easily. B. It can make small things look larger. C. It can show things in the future. D. It can give us a scene of realism. 39. In what way are plays different from film ? A. Films often use real scenery while plays don’t. B. Films can show the past while plays can’t. C. Films change scenes while plays don’t. D. Film audience can move while play audience can’t. 40. A suitable title for this text is _______. A. Stage Plays and Film B. The Powerful Camera C. Fewer Plays, More Films D. Less Waste, More Freedom |

| 第12、13题：In hopes of becoming millionaires, many Filipinos (菲律宾人) began drinking more Pepsi. They hoped to get a bottle cap with the winning number on it. In May 1992, the number was announced: 349. Thousands rushed to get their reward with their bottle caps worth a million pesos (about US $ 40,000) each. But Pepsi wouldn't pay. The company said there was a mistake. The numbers on the caps did not include a security code (保险号), so the caps were not really winners. Up to 800,000 bottle caps had the number 349. Pepsi has spent millions of dollars on the problem. The company has paid 54 million pesos to real winners. It also paid 500 pesos for each No.349 cap without the security code. 44. Which of the following is not true? A.
