Ⅲ. Reading Comprehension (45 points)
Section A (30 points, 2 for each)
Directions: There are three passages in this part. Each of the three passages 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 and mark the corresponding letter on the ANSWER SHEET with a single line through the center.
Questions 46 to 50 are based on the following passage:
To be a good teacher, you need some of the gifts of a good actor：you must be able to hold the attention and interest of your audience；you must be a clear speaker, with a good，strong, pleasing voice which is fully under your control；and you must be able to act what you are teaching，in order to make its meaning clear.
Watch a good teacher，and you will see that he does not sit motionless before his class：he stands the whole time he is teaching；he walks about，using his arms，hands and fingers to help him in his explanations，and his face to express feelings. (1)Listen to him, and you will hear the loudness, the quality and the musical note of his voice always changing according to what he is
talking about.
The fact that a good teacher has some of the gifts of a good actor doesn't mean that he will indeed be able to act well on the stage，for there are very important differences between the teacher's work and the actor's. The actor has to speak words which he has learnt by heart；he has to repeat exactly the same words each time he plays a certain part，even his move-menu and the ways in which he uses his voice are usually fixed beforehand. What he has to do is to make all these carefully learnt words and actions seem natural on the stage.
A good teacher works in quite a different way. His audience takes an active part in his play: they ask and answer questions，they obey orders, and if they don't understand something, they say so. (2)The teacher therefore has to suit his act to the needs of his audience，which is his class. He cannot learn his part by heart，but must invent ii as he goes along. I have known many teachers who were fine actors in class but were unable to take part in a stage-play because their brains wouldn't keep discipline：they could not keep strictly to what another had written.
46. A good teacher________,
A. knows how to hold the interest of his students
B. must have a good voice
C. knows how to act on the stage
D. stands or sits motionless while teaching
47. In what way is a teacher's work different from an actor's?
A. The teacher must learn everything by heart.
B. He knows how to control his voice better than an actor.
C. He has to deal with unexpected situations.
D. He has to use more facial expressions.
48. The main difference between students in class and a theater audience is that________.
A. students can move around in the classroom
B. students must keep silent while theater audience needn't
C. no memory work is needed for the students
D. the students must take part in their teachers' plays
49. A good teacher's voice________.
A. should be clear and fully under his control
B. should not be too loud or too low
C. should be fixed before he goes to class
D. all of the above
50. Why is it that some good teachers are unable to play well on the stage?
A. Nobody has taught them how to act on the stage.
B. Their audience are different.
C. It is impossible for them to do so much memory work.
D. They are not used to repeating exactly the same words.
Questions 51 to 55 are based on the following passage:
Bees do two kinds of dances to tell other bees of their discovery of food. First, there is a round dance. In this dance，the bee moves in a circle inside the hive. The round dance is used when food is close by. The food must not be more than ten meters away. (3) If a bee comes back and does a round dance, other bees know they must go out and look nearby for food. The bees also smell the bee that has found the food. The smell tells them what kind of flower to look for. After watching the round dance and smelling the bee that has found the food, the other bees can find the food source.
A second kind of dance done by the bees is a tail-wagging dance. In this dance, the bee wiggles the end of its body as it moves in a straight line. The tail-wagging dance is used when the food is more than ten meters away. The bees know from the speed of the tail-wagging dance just how far away the food source is. In the tail-wagging dance, the bees also smell the bee that has found the food. The smell tells them what kind of flower to look for. (4) After watching the tail-wagging dance and smelling the bee that has found the food, the other bees know how far to fly and what kinds of flowers to look for.
Each bee can tell all the other bees where to look for food. The bees can also tell one another if the food is especially good and how much of it there is. Karl von Frisch did an experiment with bees. He put food source very high above the bee hive，and put a bee into the food. The bee returned to the hive and did the round dance, but none of the other bees could find the food. This suggests that bees do not really have a language. One bee could not tell the
other bees the height of the food. One bee could not communicate this new information to the others.
51. Bees tell other bees that they have found food by________.
A. tail-wagging first and smelling other bees later
B. round dancing first and tail-wagging later
C. round dancing first and smelling other bees later
D. either round dancing or tail-wagging
52. What will a bee do to tell other bees about food source that is eight meters away?
A. Tail-wagging.
B. Round dancing.
C. Smelling the other bees.
D. Flying in a circle over the hive.
53. If a bee wags its tail at a very fast speed，it tries to tell other bees that________.
A. it has found a big amount of food
B. the food it has found is especially good
C. the food source is far away
D. they have to fly to the food source very quickly
54. Which of the following is NOT true according to the passage?
A. The bees that have found food carry the smell of the flowers they have found.
B. Bees can tell other bees about the quality of the food.
C. Bees can tell other bees how high the food is.
D. Bees can tell other bees about the amount of the food.
55. We can infer from the passage that________.
A. flowers are the food source of bees
B. bees cannot find food that is far away
C. Karl von Frisch's experiment shows that bees cannot really com-municate with one anther
D. bees will do round dancing if the food is twenty meters away
Questions 56 to 60 are based on the following passage:
Have you heard of the women's liberation movements? It began in the 1960s. It was started by women who were concerned about their identity，their role in society, and their work，and about the view of women that many people held. Now many American women are deeply concerned about these things. These women would like better and more interesting lives for all women around the globe.
Many people agree with the ideas and goals of women's liberation. They feel that women ought to be considered equal to men in every way. They feel that a woman should have a job outside the home and family as well. (5) They feel that a woman should be able to do anything that she wants to do and can do. Other people are opposed to women's liberation. They do not think that women should have the same jobs and the same pay as men. "they believe that men should do all of the important work. "they feel that women belong to home,
taking care of men and children. Many husbands do not want their wives to work outside the home. Some women agree with these men. People who believe in women's liberation do not feel that it is bad for a woman to remain at home if she wants to. They believe that work in the home is important and should be respected. But they want to make sure that a woman works at home because she wants to，not because she can't get a job outside the home，or because she does not believe that she can do anything useful in her community.
The women's liberation movement is trying to give women a chance to show what they can do. Perhaps a woman will find the cure for our most serious disease. Perhaps a woman will solve the energy crisis. Perhaps women and men, working together, will be able to accomplish important things better and sooner than liberation movement men would if men were working alone. If the women's is successful，we will have a chance to find out.
56.The women's liberation movement________.
A. was started by women from all over the world
B. was a major concern of all American women
C. aimed at where better and more interesting lives for all women every-
D. encouraged women to go outside to work
57. Those people who are in favor of the movement think that________.
A. men and women should be equal in every way
B. women should stay at home instead of working outside their home men should stay at home and women can do everything just raise a family as well as
men can
C. men should stay at home and raise a family
D. women can do everything just as well as men can
58. The people who are opposed to women's liberation________.
A. are strongly criticized by all women
B. think that men should do all of the important work
C. are all husbands who do not want their wives to work outside the home
D. never go outside to work
59. The attitude of the writer towards the women's liberation movement is________.
A. enthusiastic
B. cold

D. objective
60. The author seems to be in favor of the view that________.
A. women should be given a chance to show what they can do
B. work in the home is important and should be respected
C. women should have the same jobs and the same pay as men
D. all women should take part in the women's liberation movement
Section B Short Answer Questions (15 points, 3 for each)
Directions: Answer each of the questions in about 10 words.
Questions 61 to 65 are based on the following passage:
The first organized American sports cheer was created at Princeton
University in the 1860s. But organized cheerleading did not begin until 1898. That was when a student stood in front of a crowd at a game and led them in cheering for their team. That first cheerleader was Johnny Campbell at the University of Minnesota.
The University of Minnesota also led the movement to make cheerleading a sport. In the 1920s, its cheerleaders began including gymnastic movements in their cheers. This helped cheerleaders become known for their athletic ability. And cheerleading became more interesting to watch.
Most cheerleaders in the early years were men. That changed during World War Two，when large numbers of young men left the country to fight. From that time on，more than ninety percent of cheerleaders have been female.
Cheerleading quickly spread from colleges to high schools. Today most American high schools include cheerleading among their student athletic activities. Thirty percent of the high school teams enter cheerleading competitions. These cheerleaders must be in good physical condition. They must be able to jump high, turn circles in the air and lift each other. Some teams train all year long. As many as twenty-thousand girls attend cheerleading camps in the summer to improve their skills and learn new moves.
Some people say cheerleading is not a sport because it does not have unified rules. Rules for competitions among cheerleading teams are different depending on the group organizing the contest. Experts do agree, however，the cheerleading is an athletic activity requiring physical skills. They also agree that
cheerleaders add to the excitement.
1.When did organized cheerleading begin?
_____________________________________________________________.

Living off the Campus
Recently, many students choose to live off campus and rent apartments outside of the school, which raises a lot of concern.
Some people think this is all right if the students can afford the rent off the campus. They argue that with 4 to 8 students sharing a dormitory, there are often many problems arising. But some people believe it is not good for the students. In their opinion, those moving out of the school dormitories cannot focus on their study since there are many distractions outside.
As for me, I think living off campus is not a good idea for college students. Students cannot make good use of the resources in the school if they live off the campus.
