Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.Passage 1Hotlines （热线）have become common in China. Some radio 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 program.Some people know little about the topic（话题）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 by those people. It's necessary for radio stations to improve the hotline programs. In my opinion,if a caller doesn't know what is going on, the operator should not let the caller take part in it.41.We know from the sentence “Some people do nothing but break the wholeprogram" that____.( B )A. radio stations use hotlines in a wrong wayB. it is a factC. it is a good ideaD. some people have unclear thoughts42. The host has to answer and explain, ____ . ( B )A. for the host works hardB. because of the caller's ignoranceC. for the host likes talking to the callerD. because of a lot of questions raised by the caller43. The passage doesn't tell us the idea ________ . ( C )A. that some listeners phone the hotlines in funB. that some people just want to be heard by othersC. that some people who don't care what the topic is must have realized that they appear to be sillyD. what the hotline programs are44. Which of the following is not true? ( D )A. Some people know little about the topic under discussion.B. Some people do not know what the host is talking aboutC. Some people do not know what the show is aboutD. The writer tells us that the host is silly.45. What should the operator do if a caller doesn't know what is going on in the writer’s opinion?( B )A. not to let the caller call the programB. not let the caller take part in the programC. let the caller express his ideaD. feel bored by the caller Passage 2Stage plays（舞台剧）, 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（观众）cold. And even worse you’ll be wasting a powerful tool --- the camera.A stage is actually a box. One side of the box has been removed(挪开) 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.46. The main idea of the text is that ____ . ( C )A. stage plays and films are two different kinds of artB. it is always disappointing to turn play into filmsC. films have certain advantages(长处) over stage playsD. the camera has made film making easy and possible47. What is wrong with making a film by setting up a camera before the stage ? ____( D )A. Fewer and fewer people will go to the theatre.B. The audience cannot see what is going on the stage.C. The scene cannot be changed from time to time.D. The powerful camera cannot be made good use of.48. Which of the following can show that the camera is a powerful tool ? ____( B )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 （真实）.49. In what way are plays different from films? ( B )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.50. A suitable title for this text is ____.( A )A. Stage Plays and FilmB. The Powerful CameraC. Fewer Plays, More FilmsD. Less Waste, More Freedom Passage 3The human nose has given to the language of the world many interesting expressions. Of course, this is not surprising. Without the nose, we could not breathe or smell. It is the part of the face that gives a person special character. Cyrano de Bergerac said that a large nose showed a great man courageous, manly and wise.A famous woman poet wished that she had two noses to smell a rose! Blaise Pascal made an interesting remark about Cleopatra’s（古埃及王后）nose. If it had been shorter, he said, it would have changed the whole face of the world!Man’s nose has had an important role in his imagination. Man has referred to the nose in many ways to express his emotions. Expressions dealing with the nose refer to human weakness: anger, pride, jealousy（嫉妒）and revenge（报复）.In English there are a number of phrases about the nose. For example, to hold up one’s nose expressed a basic human feeling ---pride. People can hold up their hoses at people, things and places. The phrase, to be led around by the nose, shows man’s weakness. A person who is led around by the nose lets other people control him.On the other hand, a person who follows his nose lets his instinct（本能）guide him. There are a number of others. However, it should be as plain as the nose on your face that the nose in more than an organ for breathing and smelling.51. The passage is about ______. ( B )A. an organ, with which people can breathe and smellB. the nose, which gives different and useful expressionsC. the nose giving a person special characterD. interesting remarks about the nose made by some people52. From the passage we know ______. ( C )A. “Cleopatra’s nose” changed the whole face of the world indeed.B. Cleopatra had a strong will to change the whole look of the worldC. Cleopatra’s nose was not shortD. Cleopatra hoped that people would change the whole face of the world53. The nose expressed ______. ( C )A. some human weakness or otherB. people’s shortcomingsC. people’s different emotionsD. human feeling in bad sense54. A person who follows his nose ______. ( D )A. won’t take others’ adviceB. is easily controlled by othersC. is weak-mindedD. has will of his own55. How many expressions about the nose are mentioned in the passage? ( C )A. TwoB. ThreeC. FourD. FiveⅣCloze (1 20=20 POINTS)Directions: There are 10 blanks in the following passage. For each blank there are four choices marked A, B, C, and D.
