　　In my opinion，time is much valuable than money.The reason is why when money is spent，we can earn them back.But when time is gone，it will never come back.Otherwise we must value our time.

　　But lots of students don't know the valuable of time.They spend time doing so meaningless things as playing computer games，playing cards and watching TV.We don't realize that wasting time is equal to waste a part of their valuable life.

　　When she looked ahead, Florence Chadwick saw nothing but a solid wall of fog.Her body was numb (麻木的)．She had been swimming for nearly sixteen hours.

　　Already she was the first woman to swim the English Channel in both directions.Now, at age 34, her goal was to become the first woman to swim from Catalina Island to the California coast.

　　On the morning of July 4th, 1952, the sea was like an ice bath and the fog was so thick that she could hardly see her support boats.The wind was strong and it was raining heavily.Against the cold water of the sea, she struggled on—hour after hour.Millions of people at home were watching her in front of the television.

　　In one of the boats, her mother and her trainer tried their best to encourage her.They told her it wasn't much farther.But all she could see was fog.They urged her not to give up.She never had...until then.With only a half mile to go, she asked to be pulled out.

　　After thawing her cold body several hours later, she told a reporter, “Look, I'm not excusing myself, but if I could have seen land I might have made it.” It was not tiredness or even the cold water that defeated her.It was the fog.She was unable to see her goal.

　　Two months later, she tried again.This time, despite the same thick fog, she swam with all her strength and her goal clearly pictured in her mind.She knew that somewhere behind that fog was land and this time she made it! Florence Chadwick became the first woman to swim the Catalina Channel!

　　【语篇解读】　Florence Chadwick是第一个从卡特琳娜岛游到加州海岸的人。第一次，她失败了。为什么呢？因为大雾，她看不到自己的目标！

　　21．The reason why Florence Chadwick gave up for the first time was that ________．

　　A．the sea water was very coldB．she was too tired to swim

　　C．she couldn't see her goalD．she was lost in the sea

　　答案　C　[细节判断题。根据文章第四段中的It was not tiredness or even the cold water that defeated her.It was the fog.She was unable to see her goal.可知，造成Florence Chadwick放弃的原因是因为她看不到自己的目标。]

　　22．What do you know about Florence Chadwick?

　　A．She was 34 years old when she was swimming the Catalina Channel.

　　B．She was a woman who never gave up when facing difficulties.

　　C．She had few supporters except her mother and her trainer.

　　D．She was the first person to swim the Catalina Channel.

　　答案　A　[细节理解题。根据第二段及第三段第一句可知答案。]

　　23．The underlined word “thawing” in Paragraph 4 has the same meaning as ________．

　　A．tidying

　　B．warming

　　C．washing

　　D．shaking

　　答案　B　[词义猜测题。根据课文意思可知，当时的海水非常寒冷，Florence Chadwick被拉出海水后，当然是要取暖，故B为正确选项。]

　　24．The writer of the passage wants to tell us a truth that ________．

　　A．a clear goal is necessary for success

　　B．one should never mind other people's words

　　C．success can't be achieved for the first try

　　D．one should not risk doing what seems impossible

　　答案　A　[推理判断题。本文说明了Florence Chadwick第一次横渡Catalina Channel没有成功的原因是因为没有明确的目标，第二次有了明确的目标后，成功渡过Catalina Channel，因此可以推测，清晰的目标对获得成功来说是必须的。]

　　B

　　体裁：说明文　话题：医学　词数：271　时间：6′

　　As cold season approaches, many Americans will buy a lot of vitamin C and echinacea(紫锥菊)in order to avoid catching a cold.But paying attention to an old piece of advice about having enough sleep every day might be more important.

　　Research suggests that poor sleep can increase the chance to colds.Studies have shown that poor sleep and a chance to catch a cold go hand in hand, and scientists think sleep plays an important role in the body's defenses.

　　In a recent study for The Archives of Internal Medicine, scientists followed 153 men and women for two weeks, keeping an eye on their quality and duration(持续性)of sleep.Then, during a five－day period, they exposed them to cold viruses.Those who slept an average of fewer than seven hours a night, it turned out, were three times as likely to get sick as those who averaged at least eight hours a night.

　　Sleep and immunity(免疫), it seems, are tightly linked.Studies have found that mammals that require the most sleep also produce greater levels of disease-fighting white blood cells—but not red blood cells, even though both are produced in bone marrow(骨髓) and stem from the same precursor.And researchers at the Max Planck Institute for Evolutionary Anthropology have shown that species that sleep more have greater resistance against pathogens(病原体)．

　　“People who have longer sleep every night，” the Planck scientists wrote, “appear to be able to strengthen their immune systems and be better protected.”

　　【语篇解读】　随着天气变冷，越来越多的人将会感冒。如何才能在寒冷的季节避免感冒的侵袭？研究表明，充足的睡眠将会保护你不受感冒的威胁。

　　25．Which of the following can be the best title of the passage?

　　A．The Best Way to Avoid Catching a Cold in Winter.

　　B．The Relationship between Sleep and Immunity.

　　C．Lack of Sleep Increases the Risk of Catching a Cold.

　　D．How to Strengthen Your Immune Systems?

　　答案　C　[主旨大意题。通读全文可知本文主要讲述的是充足的睡眠可以减少得感冒的机会，也就是说缺乏睡眠会增加得感冒的风险。故C可作文章的标题。]

　　26．From the passage we can infer that ________．

　　A．vitamin C and echinacea can help resist colds

　　B．the longer you sleep, the healthier you will be

　　C．people didn't know the relationship between sleep and colds before

　　D．people's immunity can be gained mostly from sleep

　　答案　A　[推理判断题。根据短文第一句可知答案。B项没有依据；C项根据But paying attention to an old piece of advice about having enough sleep every day might be more important可排除；D项没有依据。]

　　27．We can draw a conclusion from the third paragraph that ________．

　　A．most people sleep less than seven hours a day

　　B．sleep less may easily lead to some illnesses

　　C．one should sleep at least seven hours a day

　　D．sleep is the best way to treat illnesses

　　答案　B　[细节理解题。根据第三段内容可知，从这项研究中可以得出结论：睡眠少很容易导致疾病。]

　　28．How does the author express his idea?

　　A．By using the results of studies.B．By comparing some numbers.

　　C．By telling some interesting stories.D．By referring to some theories.

　　答案　A　[细节理解题。作者为了说明睡眠不足可导致感冒的风险，多次提到了研究的结果。故答案为A。]

　　.阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。
