第三部分：閱讀理解（共兩節(jié)，滿分40分）
第一節(jié)：選擇題（共17小題；每小題2分，滿分34分）
閱讀下列短文，從每題所給的四個(gè)選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)。
A
Children have their own rules in playing games. They seldom need a judge and rarely trouble to keep scores. They don’t care much about who wins or loses, and it doesn’t seem to worry them if the game is not finished. Yet, they like games that depend a lot on luck, so that their personal abilities cannot be directly compared. They also enjoy games that move in stages, in which each stage, the choosing of leaders, the picking-up of sides, or the determining of which side shall start, is almost a game in itself.
Grown-ups can hardly find children’s games exciting, and they often feel puzzled at why their kids play such simple games again and again. However, it is found that a child plays games for very important reasons. He can be a good player without having to think whether he is a popular person, and he can find himself being a useful partner to someone of whom he is ordinarily afraid. He becomes a leader when it comes to his turn. He can be confident, too, in particular games, that it is his place to give orders, to pretend to be dead, to throw a ball actually at someone, or to kiss someone he caught.
It appears to us that when children play a game they imagine a situation under their control. Everyone knows the rules, and more important, everyone plays according to the rules. Those rules may be childish, but they make sure that every child has a chance to win.
56. What is true about children when they play games?
A. They can stop playing any time they like.
B. They can test their personal abilities.
C. They want to pick a better team. D. They don’t need rules.
57. To become a leader in a game the child has to ______.
A. play well B. wait for his turn
C. be confident in himself D. be popular among his playmates
58. What do we know about grown-ups?
A. They are not interested in games.
B. They find children’s games too easy.
C. They don’t need a reason to play games.
D. They don’t understand children’s games.
59. The writer believes that _______.
A. children should make better rules for their games
B. children should invite grow-ups to play with them
C. children’s games can do them a lot of good
D. children play games without reasons
B
Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judge are softer on attractive defendants（被告）.But in the executive (主管的)circle, beauty can become a liability.
While attractiveness is a positive factor for a man on his way up the executive leader, it is harmful to a woman. Handsome male executives were considered as having more honesty than plainer men: effort and ability were thought to lead to their success.
Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck. All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was connected more to personal relationships and less to ability than that of the attractive overnight successes.
Why are attractive women not thought to be able? An attractive woman is considered to be more feminine and an attractive man more manly than the less attractive ones. Thus, an attractive woman has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the “manly” qualities required.
This is true even in politics. “When the only clue is how he or she looks, people treat men and women differently,” says Anne Brown, who recently published a study on the effects of attractiveness on political candidates. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.
The results showed that attractive males completely defeated unattractive men, but women who had ranked most attractive unchangeably received the fewest votes.
60. The underlined word “l(fā)iability” (Para1) most probable means _______.
A. disadvantage B. advantage C. misfortune D. trouble
61. In traditionally female jobs, attractiveness_______.
A. makes women look more honest and capable
B. strengthens the feminine qualities required
C. is of great importance to women
D. often enables women to succeed quickly
62. Bowman’s experiment shows that when it comes to politics, attractiveness
________.
A. turns out to be a disadvantage to men
B. is more of a disadvantage than an advantage to woman
C. affects men and women alike
D. has as little effect on men as on women
63. It can be inferred from the passage that people’s views on beauty are often__.
A. practical B. supportive C. old-fashioned D. one-sided
64. The author writes this passage to ______.
A. give advice to job-seekers who are attractive
B. discuss the disadvantages of being attractive
C. demand equal rights for women D. state the importance of appearance
C
Congratulations, Mr. Jones, it’s a girl.
Fatherhood is going to have a different meaning and bring forth a different answer from every man who bears these words. Some feel proud when they receive the news, while others worry, wondering whether they will be good fathers. Although there are some men who like children and may have had considerable experience with them, others do not particularly care for children and spend little time with them. Many fathers and mothers have been planning and looking forward to children for some time. For other couples, pregnancy（懷孕）was an accident that both husband and wife have accepted willingly or unwillingly.
Whatever the reaction to the birth of a child, it is obvious that the change from the role of husband to that of father is a difficult task. Yet, unfortunately, few attempts have been made to educate fathers in this re-socialization process. Although many good books have been written about American mothers, only recently have some books discussed the role of a father.
It is argued by some writers that the transition to the father’s role, although difficult, is not nearly as great as the transition the wife must make to the mother’s role. The mother’s role seems to require a complete transformation of daily routine and adaptation to a new life, on the other hand, the father’s role is less demanding and immediate. However, even though we have mentioned the fact that growing numbers of women are working out of home, the father is still thought by many as the breadwinner in the household.
65. According to the author, being a father ________.
A. brings a feeling of excitement to some men
B. has a different meaning for those who have daughters
C. makes some men feel proud and others easy
D. means nothing but more responsibilities
66. It is stated in the passage that ________.
A. some parents are not prepared to have a child
B. young couples do not like children at all
C. working couples do not have much time to take care of their children
D. many parents look forward to having a boy as their first child
67. The transition to the mother’s role requires that the wife ______.
A. changes her life style in a quite different way
B. makes a complete change in her everyday life to deal with the new situation
C. stays at home to take care of the baby
D. helps her husband in his re-socialization process
68. Some writers argue that with respect to the change of roles, fathers, compared
with mothers, _________.
A. have to do more in the household
B. have to make more difficult adaptations
C. have an easier job to do
D. can usually do a better job
D
Dr. Wiseman started the “l(fā)augh lab” project in September 2001. It is the largest study of humour. Participants are invited to log（登錄）on to the laugh lab website, give a few personal details, tell their favourite jokes and judge the jokes told by other people.
The project will last for a year, and the organizers hope to finally discover the world’s funniest joke. But there is also a serious purpose. The researchers want to know what make people from different nations and cultures find funny. And they want to find out the differences between the male’s and female’s sense of humour. The idea is that we want to understand each other, we have to find out what makes us laugh.
This is a subject that has long interested psychologists and philosophers. Most of the time, people are not completely honest. We do things that society expects us to and say things that help us get what we want. But laughing cannot be controlled. When we laugh, we tell the truth about ourselves. By December 2001 over 10,000 jokes had been submitted. This gave the scientists enough evidence to make early conclusions. It seems that men and women do have different senses of humour, for instance.
“Our findings show the major differences in the ways in which males and females use humour,” said Dr. Wiseman. “Males use humour to appear superior to others, while women are more skilled in languages and prefer word play.”
Researchers also found that there really is such a thing as a national sense of humour. The British enjoy what is usually called “toilet humour”. But the French like their jokes short and sharp: “You’re a high priced lawyer. Will you answer two questions for 500?” “Yes. What’s the second question?” The Germans are famous for not having a sense of humour. But the survey found that German participants were more likely to find submitted jokes funny than any other nationality. Perhaps that proves the point. Is this joke funny? I don’t know, but let’s say yes, just to be safe.
Dr. Wiseman and his workmates also submitted jokes created by computer. But none of those who took part in the survey found any of them amusing. Perhaps this is relief. Computers already seem like they can do everything. At least they should leave the funny stuff to us.
69. We can infer from the passage that ________.
A. most of the people all over the world are completely honest
B. psychologists and philosophers take interest in the “l(fā)augh lab” project
C. ordinary people are not interested in the “l(fā)augh lab” project at all
D. people tell the truth about themselves only when they laugh
70. What is the main idea of the 4th and 5th paragraph?
A. Man and woman have different senses of humour.
B. Male and female have similar senses of humour.
C. About 10,000 jokes have been submitted from September 2001 to December 2001.
D. Scientists have collected enough evidence to make conclusions.
71. The writer gave the examples of the British, the French and the Germans _________.
A. to show that people from different nations have different senses of humour
B. to prove the British people have a sense of “toilet humour”
C. to show French people have a better sense of humour
D. to prove that the Germans have no sense of humour
72. Which statements is TURE according to the passage?
A. The jokes created by computer are less funny than those by humans.
B. The Germans cannot find the submitted jokes amusing.
C. Males are better at word play compared with women.
D. Female like to use humour to show that they are superior.
第二節(jié)：簡(jiǎn)答題（共3小題；每小題2分，滿分6分）
閱讀下面短文，根據(jù)第73至第75小題的具體要求，簡(jiǎn)要回答問(wèn)題。
So long as teachers fail to
distinguish between teaching and learning, they will continue to undertake to
do for children that which only children can do for themselves. Teaching
children to read is not passing reading on to them. It is certainly not endless
hours spent in activities about reading.
Teaching and learning are two different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in exploring knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teachers fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of learning to read by reading.
73. Find in the passage a word closest in meaning and use its other form to explain the underlined word “occupation”.
74. What does it mean according to the author if teachers can enable students to develop their own way of reading?（回答詞數(shù)不超過(guò)8個(gè)）
75. What is the main idea of the passage?（回答詞數(shù)不超過(guò)8個(gè)）

Do you think that daydreaming is a waste of time? Probably so.
“On the contrary,” says L.Giambra, an expert in psychology, “Daydreaming is quite necessary. Without it, the mind couldn’t get done all the thinking it has to do during a normal day…You can’t possibly do all your thinking with a consciousness. Instead, your unconscious mind is working out problems all the time. Daydreaming then may be one way that the unconscious and conscious states of mind have silent dialogues.”
Early psychology experts paid no
attention to the importance of daydreams or even considered them harmful. At
one time daydreaming was thought to be a cause of some mental illnesses. They
did not have a better understanding of daydreams until the late
Daydreams are usually
very simple and direct, quite unlike sleep dreams, which may be hard to
understand. It’s easier to gain a deep understanding of your life by paying
close attention to your daydreams than by trying to examine your sleep dreams
carefully. Daydreams help you recognize the difficult situations in our life
and find out a possible way of dealing with them.
Daydreams cannot by predicted. They move off in unexpected directions which may be creative and full of ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy.

Generation Gap
Nowadays there is often a lack of understanding between parents and children. This is called generation gap. Many parents say that their children are behaving unreasonably. Many a child complains that they can’t communicate with their parents. Their parents are unwilling to accept anything new.
I think the lack of communication between parents and children is the most obvious reason. As they grew up at different times, they have many different likes and dislikes. Besides, both of them are so busy with their work or study that they don’t spare enough time to exchange ideas. Therefore, misunderstanding arises between them.
To understand each other better, both parents and children need to make efforts. They should often communicate with each other and spend more time talking with each other. Only in this way will they bridge the generation gap.
