阅读下面短文, 掌握其大意, 然后从 21-40 各题所给的四个选项 (A、B、C和D) 中, 选出最佳选项。
It has been difficult to sit on the bench the majority of my high school basketball career. To watch my team from the sideline and 21 why I am not good enough to be on the floor. 22
endless hours of work and devotion, pushing myself through drill after drill, the 23 thing I want is to be a cheerleader. The feeling of being 24 is sometimes too much and drives me to
25 on the spot. I often feel as though my efforts are wasted and my time is eaten away, devoted to 26 .
It is heartbreaking to be a spectator(旁观者) for the game I love, knowing that no one has enough 27 to give me the chance to 28 on the floor. Tears well up, but I hold them back. I shouldn’t be so 29 over something so silly.
Away from the game, it’s easier to put my thoughts together, 30 letting my emotions drive my reasoning. I consider 31 I am where I am. I have played basketball my whole life. I have a passion for the 32 and always have. There is nothing like the excitement of 33 : the swish of the net, the sweat rolling off my cheeks, even the bruises(青肿) are battle wounds worn 34 after every game.
Even if I don’t play much, I participate in every 35 . I am part of a team of girls who
36 together like a family. I am there for them, 37 they are for me.
Should I move on? Or should I stay with my team and pursue my passion just a little longer?
The decision isn’t difficult when I consider the 38 that being a part of a team brings me— and not just any team, 39 my team. I love basketball and my teammates. When I think about that, my view from the bench really isn’t so bad 40 .

举一反三
Scientists, for several years, have been studying how noise affects people and animals and are alarmed by what they have learned.
Peace and quiet are becoming harder to find. Noise pollution is no joke. It is a threat that should be looked at carefully.
Sound is measured in units called decibels （分贝）. At a level of 140 decibels people feel pain in their ears.
Trucks, buses, motorcycles, airplanes, boats, and factories all make noise. This noise bothers not only our ears, but our minds and bodies as well.
There is a saying about "it is so noisy that you can"t hear yourself think". Doctors who study noise believe that we must be able to hear ourselves think most of the time. If we don"t, we may have headaches, other aches and pains, or even mental problems. Noise adds even more tension to a society which already faces too much stress.
49．The sense of hearing _______.
A．makes people feel angry
B．makes people want to dance
C．helps people to know what is happening around them
D．is something harmful to people
50．When sound is turned into noise, _______.
A．people become ill B．it makes people forget the past
C．people don"t know how to deal with it D．it becomes a kind of pollution
51．Why does the passage say " Peace and quiet are becoming harder to find " ?
A．Sounds of over 140 decibels are common these days.
B．There are always wars going on in the world.
C．The world is making more and more noise.
D．All kinds of machines make noises.
52．Which of the following statements is TRUE?

More than 87 million tickets were bought for the Pennsylvania lottery drawing. Those who bought tickets had to choose seven numbers from 1 to 80. The chance of winning was one in 9．6 million. But that little chance certainly didn’t affect ticket sales. In the last few days before the drawing , tickets were selling at the unbelievable rate of 500 per second.
Experts say many people buy lottery tickets because they just want to have a piece of the action. Others say the lottery is a stock market for poor people. It allows them to dream about wealth they’ll probably never have.
But many people believe lotteries are no better than legalized gambling. Some critics note that most people who play are poor and may not be able to afford the tickets. There are also many addicts who take the game seriously. They may pour their life savings into lottery tickets. Some clubs have been formed to help them kick the habit.
Politicians like lotteries because they provide money that would otherwise have to some from new taxes. The profits from lotteries are usually used to pay for education or programs for senior citizens. But critics say this arrangement just allows states to legalize vice（恶习）, under the name of social progress. No matter whether you regard state lotteries right or not , you cannot refuse to accept their extreme popularity with many Americans.
57. The main idea of the passage is that ．
A．lotteries are of great benefit to everyone who buys them
B．playing a lottery is just like investing in the stock market
C．a lot of people buy lottery tickets , but lotteries cause disagreement

D．People love the lottery because it is a stock market ．
59. In just one hour in the last few days , the Pennsylvania lottery sold tickets totaling ．
A．$1．62 million B．$90million C．$9．6million D．$87million
60. People who are addicted to playing lotteries should ．
A．join a club B．save every cent
C．win the Pennsylvania D．kick the habit
“Cool”can be used to express feelings of interest in almost anything.When you see a famous car in the street，maybe you will say，“It"s cool．”You may think，“He"s so cool，”when you see your favourite footballer．
We all maximize（扩大） the meaning of“cool”．You can use it instead of many words such as “new” or “surprising”．Here"s an interesting story we can use to show the way the word is used．A teacher asked her students to write about the waterfall（瀑布）they had visited．On one student"s paper was Just the one sentence，“It"s so cool．”Maybe he thought it was the best way to show what he saw and felt．
But the story also shows a scarcity（缺乏）of words．Without “cool”，some people have no words to show the same meaning．So it is quite important to keep some credibility（可信性）．Can you think of many other words that make your life as colourful as the word “cool”？ I can．And I think they are also very cool．

One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead—take me away.”
But there’s a twist to Choe’s discovery. Choe says that the living ants—not just the dead ones —have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it’s telling other ants that it’s dead.
What keeps ants from dragging away the living ants? Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait—I’m not dead yet.” So Choe’s research turned up two sets of chemical signals in ants: one says, “I’m dead,” and the other set says, “I’m not dead yet.”
Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive.
Choe suspects that when an Argentine ant dies, the chemical that says “Wait- I’m not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I’m dead” is left. “It’s because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases new unique chemicals after death,” said Choe. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body.
Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests.The ants’ removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe. “Think about all the effort and money that we invest daily in waste management.”
51. The underlined word “twist” in Paragraph 3 means _____.
A. an unexpected change B. a clear mistake
C. an important key D. a shocking conclusion
52. Ants judge whether another one is dead or not depending on ______.
A. the sense of taste B. the sense of smell
C. the sense of touch D. the sense of sight
53. The result of the research can be used to ______.
A. kill troublesome pests
B. solve the problem of endangered species
C. prevent further expansion of the ants’ territory
D. keep the balance of nature
54. Why is it important to remove dead individuals?
A. Because it is easier to manage the living.
B. Because it can save money to deal with the waste.
C. Because it can provide more space for the living.
D. Because it can keep the living from suffering disease.
55. What might be the best title of the text?
A. Dead or living? It is easy to judge
B. Pulling away the dead ants is a difficult task
C. Ant nests have great undertaking capacity
D. Leaving it alone or taking it away? Ants feel puzzled
Al Herpin was 90 years old when the doctors came to his home in New Jersey. They thought for sure that he got some sleep of some kind. So they stayed with him and watched every movement he made. But they were surprised. Though they watched him hour after hour and day after day, they never saw Herpin sleeping. In fact, he did not even own a bed. He never needed one.
The only rest that Herpin sometimes got was sitting in a comfortable chair and reading newspapers. The doctors were puzzled by this strange continuous sleeplessness. They asked him many questions, hoping to find an answer. They found only one answer that might explain his condition.
