第二部分：阅读理解（共两节，满分40分）
第一节（共15小题，每小题2分，满分30分）
阅读下列四篇短文，从每小题后所给的A.B.C.D四个选项中，选出最佳选项，并在答题卡上将该选项涂黑。
A
Shay asked, “Do you think they’ll let me play？” Shay’s father knew that most of the boys would not want someone like Shay on their team, but the father also understood that if his son, mentally and physically disabled, were allowed to play, it would give him a much-needed sense of belonging and some confidence.
Shay’s father approached one of the boys on the field and asked if Shay could play, not expecting much. The boy looked around and said, “We’re losing by six runs （分） and the game is in the eighth inning （局）.I guess he can be on our team and we’ll try to put him in to bat in the final inning.
Shay struggled over to the team’s bench and put on a team shirt with a broad smile and his father had a small tear in his eye and warmth in heart. The boys saw the father’s joy at his son being accepted.
In the bottom of the eighth inning, Shay’s team scored a few runs but was still behind by three. In the top of the final inning, Shay put on a glove and played in the field. Even though no hits came his way, he was obviously joyful just to be in the game and on the field. In the bottom of the final inn ing, Shay’s team scored again. Now, Shay was scheduled to be next at bat. Would they let Shay bat and give away their chance to win the game？
Surprisingly, Shay was given the bat. Everyone knew that a hit was almost impossible. The first pitch （投） came and Shay missed. The pitcher again took a few steps forward to throw the ball softly towards Shay. As the pitch came in, Shay swung at the ball and hit a slow ground ball right back to the pitcher.
The pitcher could have easily thrown the ball to the first baseman and Shay would have been out and that would have been the end of the game .Instead, the pitcher threw the ball right over the head of the first baseman, beyond the reach of all teammates. The audience and the players from both teams started screa ming,“Shay, run to first! ”Never in his life had Shay ever run that far but made it to first base, wide-eyed and shocked..
Everyone should, “Run to second!” Catching his breath, Shay awkwardly ran towards second. By the time Shay rounded towards second base, the smallest guy on their team, who had a chance to be the hero for his team fir the first time, could have thrown the ball to the second baseman, but he understood the pitcher’s intentions and he too intentionally threw the ball high and far over the third baseman’s head.
All were screaming，“Shay，Shay，Shay，all the way Shay.” Shay reached third base when one opposing player ran to help him and shouted, “Shay, run to third.” As Shay
rounded third, all were on their feet, crying,“Shay, run home!”Shay r an to home, stepped on the home base and was cheered as the hero who won the game for his team.
That day, the boys from both teams helped bring a piece of true love and humanity into this world. Shay didn’t make it to another summer and died that winter, having never forgotten being the hero and making his father so happy and coming home and seeing his mother tearfully hug her little hero of the day!
46.Not expecting much, Shay’s father still asked the boy if Shay could play, mainly because the father _________.
A. noticed some of the boys on the field were heisting
B. guessed his presence would affect the boy’s decision
C. learned some of the boys on the field knew Shay well
D. understood Shay did need a feeling of being accepted
47. In the bottom of the final inning Shay was given the bat because the boys _________.
A. believed they were sure to win the game
B. would like to help Shay enjoy the game
C. found Shay was so eager to be a winner
D. fell forced to give Shay another chance
48. The smallest boy threw the ball high and far over the third baseman’s head, probably because that boy ________.
A. was obviously aware of the pitcher’s purpose
B. looked forward to winning the game for his team
C. failed to throw the ball to the second baseman
D. saw that Shay already reached second base
49. What to you think is the theme of the story？
A. True human nature could be realized in the way we treat each other.
B. Everyone has his own strength even if mentally or physically disabled.
C. Everyone can develop his team spirit in sports and please his parents.
D. The results of the game should not be the only concern of the players.
B．
Millions of women use cosmetics, often called “make-up”. The cosmetics industry is one of the biggest in the world. Most large stores sell cosmetics, and there are always shops at airports selling them cheaply. The word “cosmetics” refers to anything that people put on their faces to make them look better. Lipstick, face powder and cream, and eye make-up are the most popular. Although more women than men use cosmetics, there are cosmetics for men as well as women.
Some people even have cosmetic surgery to make their faces look different. They have the shape of their noses and eyes changed.
The most widely used cosmetic is probably lipstick, as many women who do not wear any other make-up will often put on a little lipstick.
Lipstick is made by mixing together different oils and colors. This mixture is then allowed to get hard and is cut into the shape of a small pencil. When a woman presses the lipstick to her lips, the end of it becomes soft, and some of it sticks to her lips, giving them extra color.
Cosmetics were probably first used in India, but it was the Egyptians, six thousand years ago, who made the most use of them. Rich Egyptian women painted their eyes green and black.
They used a red color to paint pretty designs on their fingernails, the palms of their hands and the soles of their feet. Pictures of Cleopatra always show her wearing a lot of make-up.
The Romans also used cosmetics. They liked to make their skin very white and to paint their eyes. They also used a kind of lipstick.
In England at one time, very rich women had baths in milk to make their skin beautiful. They also used a lot of sweet-smelling powder to stop people smelling their bodies, which were often very dirty because they did not wash very often or change their clothes. At one time, some cosmetics were not safe. They were bad for the skin and some of the lipsticks and powders that people used were even poisonous. Nowadays, people in the cosmetics industry take great care to make sure that everything they use is completely safe.
50. What does the word “Cosmetics” refer t o ________.
A. lipstick
B. make-up
C. creams
D. surgery
51. According to the passage people use cosmetics ________.
A. only at airports
B. only to color their feet
C. to make themselves look better
D. instead of surgery
52. From the passage we know that in earlier times ________.
A. cosmetics were never used in milk baths
B. cosmetics were never used on the eyes
C. cosmetics were never used on the skin
D. sometimes cosmetics were harmful to the skin
53. Which of the following statements is true？
A. In order to make their faces look different some people even have cosmetic surgery.
B. In England, women have baths in milk to make their skin beautiful.
C. Cosmetics were probably first used by the Egyptians six thousand years ago.
D. Not all cosmetics are safe so we should be careful to use them.
C．
I take the firm position that parents do not owe their children a college education. If they can afford it, they can certainly send them to the best universities. But they must not feel guilty if they can't. If the children really want to go, they'll find a way. There are plenty of loans （货款）and scholarships for the bright and eager ones who can't afford to pay.
When children grow up and want to get married, their parents do not owe them a down payment on a house. They do not have the duty to baby-sit their grandchildren. If they want to do it, it must be considered a favor not an obligation.
Do parents owe their children anything？Yes, they owe them a great deal.
One of their obligations is to give their children a personal worth. A child, who is constantly made to feel stupid and unworthy, constantly compared with brighter brothers, sisters, or cousins will become so unsure, so afraid of failing that he （or she） won't try at all. Of course they should be properly corrected when they do wrong, but it's often better to let children learn their mistake by themselves in time. All our parents should do is to trust them, respect them, tolerate（宽容） them and give them chances to try and fail. They must learn to stand failure. When criticisms（批评） are really needed, they should be balanced with a smile and a kiss. That is the way children learn.
Parents owe their children a set of solid values around which to build their lives. This means teaching them to respect the rights and opinions of others; it means being respectful to elders, to teachers, and to the law. The best way to teach such values is by deed. A child who is lied to will lie. A child who sees no laughter and no love in the home will have difficulty laughing and loving.
No child asks to be born, If you bring a life into the world, you owe the child something.
54. According to the author, ________.
A. parents must support their children even after they married as a duty.
B. if they don't afford, parents should take loans to send their children to go to college.
C. parents needn't feel guilty if they are unable to send them to university.
D. parents should give their children a down payment on a house.
55. The author mainly talks about in this passage________.
A. the duties of the parents
B. the best way to teach their children.
C. the reason why children feel stupid and unworthy.
D. why parents owe their children something.
56. What does the underlined word “obligation” mean in the second paragraph？
A. duty
B. debt
C. right
D. blame
57. According to the author what should parents do when children make mistakes？
A. criticize and correct them immediately.
B. let children learn their mistake by themselves in time.
C. tolerate them and tell them not to do that again.
D. compare them with brighter brothers, sisters.
D.
When talking about French literature, Guy de Maupassant （1850-1893） is often the first name that comes to mind for Chinese readers.
The master of short story-telling was brought in Normandy（诺曼底） in northwest France. In 1869, he went to study law in Pairs but one year later, aged 20, he volunteered to serve in the army during the Franco-Prussian War（普法战争）.
Returning to Pairs in 1871，Maupassant worked as a civil servant for eight years. His rich experience offered good subject matter for his writing. And he learned a lot through spending time with other French literary masters such as Gustavo Flaubert. By 1880, Maupassant had established himself in the literary world with his first short story, “Ball of Fat”.
Over the course of his life, he wrote 300 short stories and six novels, using sad tales of Norman peasant life, the Franco-Prussian War and the fashionable life of Pairs as his subject matter. He presents his characters in a simple and objective way, describing them as unhappy victims（牺牲品）of their greed（贪婪）, desire or vanity（虚荣）.
During his final years of life, Maupassant suffered from mental illness. He died in 1893 at the age of 43.
58. Which of the following works made Maupassant establish himself in the literary world_______？
A. Pierre and Jean
B. Ball of Pat
C. The heritage
D. The Necklace
59. which of the following did Maupassant use as his subject matter？
A. sad tales of Norman peasant life
B. the Franco-Prussian War
C. the fashionable life of Pairs
61. ________
There are many occasions （场合）for giving gifts in modern industrialized societies; birthdays, naming ceremonies, weddings, anniversaries, New Year, It is common to give gifts on
many of these celebrations in western cultures. In addition, special events, such as one’ s first day of school or graduation from university, often require gift giving.
62. ________
What is happening when we give gifts？Most important, we are exchanging gifts. If someone gives me a gift for my birthday, I know that I am usually expected to give one on his or her next birthday. A gift builds up or confirms a social obligation （义务）.
63. ________
Gifts tighten personal relationships and provide a means of communication between loved ones. People say that a gift lets the recipient （接受者） know we are thinking of them, and that we want to make the person “feel special.”We want people to feel wanted, to feel part of our social or family group. We give presents to say “I’m sorry. ”Sometimes it is difficult for us to find a present that someone will like. Sometimes we give things that we like or would feel comfortable with. In all these cases, the gifts are sending out messages—often very expressive ones.
64. ________
People tend to talk about presents in a fairly loving way. A woman whose mother had died years ago described the many gifts around her house. These were gifts that her mother had given her over the years：“I appreciate these, and they me an something to me, ” the woman said, “because I remember the occasions they were given on, and that they were from my mother, and the relationship we’ve had. ” The gifts remain and keep the relationship alive in mind. This woman felt the same way about the gifts she gave to others. She hoped that the recipients would look at her gifts in years to come and remember her.
65. ________
Emotions （情感） like these suggest that a positive spirit still lies behind gift giving. They prove that the anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful. Studies in Canada and elsewhere have also shown that this is not the case. Each gift is unique even if so many are given. The emotional benefit for those who exchange gifts is the very reason for the tradition to continue.
