1.Molly Wilson had been a dancer and a mother for many years when she decided to sail round the world to raise money for charity. As a child she had trained as a ballet dancer, but at 15 she had grown too tall for classical ballet, so she became a member of a pop dance team. She got married, and after she had children she retired from show business to bring them up. They grew up, and when they were 18 they left home. She says, "When I decided to do the round-the-world race, my husband thought I was bored because the children had left home. He was also worried because I had never sailed before. I was not bored, but I had met some people who told me about the race. They had taken part in it, but they had only done one section, say, from New Zealand to Australia. I wanted to do the whole ten-month journey." Before Molly left she did a lot of training, but it hadn't prepared her for the worst weather which they experienced. She tells one story. 'One night the sea was very rough and it was very cold. I had gone downstairs when a huge wave smashed into the boat and injured two men on the deck. One of the men couldn't move because he had broken his leg. They were taken to hospital by helicopter. That was the worst time.' By the end of October last year, she had raised more than ?50,000 for charity. She says, 'Sometimes I ask myself, what did I do? How did I do it? But then I think, it's the same as being a dancer. Before I left on the trip, I had trained hard. I had got very fit and had prepared myself completely. Then on the trip I was simply a good team member.'1.What does the word 'extraordinary' mean in the title?2. The sentence "?my husband thought I was bored ?" in Para. 4 meant that my husband thought I felt().3. The word 'section' in Para. 4 most probably means here ().4. Which of the following is nearest (closest) in meaning to 'rough' in the sentence 'One night the sea was very rough ?' in Para. 5?5. The last paragraph suggests that ().(1).A、very ordinaryB、very unusual and surprisingC、not special(2).A、dissatisfied because I had nothing better to do at homeB、annoyed because I had to wait long for my children to come back homeC、sad because all the children left me when they grew up(3).A、group of the jobB、part of the trainingC、part of the route of sail(4).A、not exactB、difficultC、not smooth because of huge waves(5).A、the qualities she needed for the trip were the same as those for a dancerB、many years of dancing had already prepared her for the sail completely, so she needn't do anything before the journeyC、she should not forget dancing during the trip

4.The journey two divers(潜水员)made some time ago to the very deepest point on the earth make us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small ball to find out if there are any ocean currents(水流)or signs of life.It was necessary to set out early, so that the ball would come to the surface in daylight, and so be easily found by the mother ship which would be waiting for it. The divers began preparations(准备)early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.The divers felt as if they were going down steps as they passed through warm and cold layers(层)of water. In time, the temperature dropped to freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth(深度)of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking(爆裂)noise: even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer(外部的)windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea-creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure(压力). But they did not dare to leave the lights on for long , as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint(微弱的)but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none the worse for their experience.1. The purpose of the diver's journey to the deepest point on the earth was to find _____.A. if there are water currents and life in the great depthsB. if people can stand the severe cold in the great depthsC. if there are steps in the great depthsD. if the telephone works well in the great depths2. The divers set out early in the morning so that _____.A. they could return to the surface during the dayB. they could see at the bottom of the oceanC. they could avoid the cold at nightD. they could stay long at the bottom3. Which of the following statements is true?A. The ocean water temperature decreases steadily with the depthB. There are steps on the way to the bottom of the Pacific OceanC. There are steps between the water layers of different temperatureD. The water layers of different temperatures made the divers feel as if they were going down steps4. As the divers went down to the ocean floor, the telephone _____.A. kept working all the timeB. stopped working at a depth of 3,000 feet and began working again after they reached the bottomC. stopped working at a depth of 3,000 feet and began working at 30,000 feetD. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth5. On the ocean floor, the divers found that _____.A. there was no life but some small dead sea-creaturesB. fish were swimming as freely as they do near the surfaceC. fish were not swimming freely in the dark waterD. fish were not swimming freely under the high water pressure

    Common-cold Sense
    You can't beat it,but you don't have to join it.Maybe it got the name"common cold"because it's more common in winter.The fact is,though,being cold doesn't have anything to do with getting one.Colds are caused by the spread of rhinoviruses,and,at least so far,medical science is better at telling you how to avoid getting one than how to get rid of one.
    Children are the most common way cold viruses are spread to adults,because they have more colds than adults-an average of about eight per year.Why do kids seem so much more easily to get colds than their parents?Simple.They haven't had the opportunity to become immune to many cold viruses.
    There are more than 150 different cold viruses,and you never have the same one twice.being infected by one makes you immune to it-but only it.
    Colds are usually spread by direct contact,not sneezing or coughing.From another person's hand to your hand and then to your nose or eyes is the most common route.The highest concentration of cold viruses anywhere is found under the thumbnails of a boy,although the viruses can survive for hours on skin or other smooth surfaces.
    Hygiene is your best defense.Wash your hands frequently,preferably with a disinfectant soap,especially when children in your household have colds.
    But even careful hygiene won't ward off every cold.So,what works when a coughing,sneezing, runny nose strikes?
    The old prescription of two aspirins,lots of water,and bed rest is a good place to start.But you'll also find some of the folk remedies worth trying.Hot mixtures of sugar(or honey),lemon,and water have real benefits.

    When you are having a cold,______.
    A:it is always the same kind of cold that you had last time
    B:it may be the same kind of cold that you had last time
    C:it is certainly not the same kind of cold that you had last time
    D:it is probably not the same kind of cold that you had last time

    答案:C
    解析:
    由文章第一段最后一句可知,感冒是由于一种鼻病毒的传播而引起的,故选B。
    由文章第五段第一句可知,保持卫生是应对感冒的最好防御,故选A。
    由文章第二段最后一句可知,儿童对很多病毒还不具有免疫性,因此他们更易患感冒。故选B。
    由文章第三段内容可知,一个人绝不会被同一种感冒病毒感染两次,和C项的表述内容相符,故选C。
    由文章倒数第二段第二句的内容可知, 当一个人患感冒时,会出现咳嗽.打喷嚏以及流鼻涕的症状,而未提及有胃疼症状,故选D。

    D.to show that the water in the Weddell Sea varies in salinity from place to place

    When did you last see a polar bear?On a trip to a zoo,perhaps?If you had attended a winter activity in New York a few years ago,you would have seen a whole polar bear club.These"Polar Bears"are people who-meet frequently in winter to swim in freezing cold water.That day,the air temperature was 3oC,and the water temperature was a bit higher.The members of the Polar Bear Club at Coney Island,New York are usually about the age of 60.Members must satisfy two requirements.First,they must get along well with everyone else in the group.This is very important because there are so many different kinds of people in the club.Polar Bears must also agree to swim outdoors at least twice a month from November through February.
    Doctors do not agree about the medical effects of cold-water swimming.Some are worried about the dangers of a condition in which the body′s temperature drops so low that finally the heart stops.Other doctors,however,point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.
    The Polar Bears themselves are satisfied with the benefits(or advantages)of cold-water swimming.They say that their favorite form of exercise is very good for the circulatory system(循环系统)because it forces the blood to move fast to keep the body warm.Cold-water swimmers usually turn bright red after a few minutes in the water.A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.
    The main benefits(or advantages)of cold-water swimming are probably mental.The Polar Bears love to swim year-round;they find it fun and relaxing.As one 70-year-old woman says,"When I go into the water,I pour my troubles into the ocean and let them float away."

    D:it is probably not the same kind of cold that you had last time

    答案:C
    解析:
    第一段虽然提到了感冒常发生子冬天,但紧接着提到,受凉并不会导致感冒,所以A项 不是正确答案。由文章第四段第一句可知,感冒通常是由于与感冒的人身体直接接触而导致 的,而不是由于打喷嚏或咳嗽传染的,所以C项也不是正确答案。D项歪曲文章意思,选项B 与第一段第四句的意义相吻合,因此是正确答案。
    文章第五段第一句话“Hygiene is your best defense.”的意思是“卫生是你的最佳防御。” 因此A项是正确答案。在本段第二句提到的用消毒肥皂洗手,是保持卫生的手段之一。
    第二段中提到儿童平均一年得8次感冒,这是一个统计数据而不是儿童得感冒的原因; 文中并没有说“儿童从不洗手”;文中也没有说“儿童不喜欢吃柠檬”;所以A、C、D三项都不 对。B项与第二段最后一句意思一样,是正确答案。
    第三段提到有150多种感冒病毒,而人们绝不会被同一种病毒侵害两次,因为人得了一 次感冒后对相应的病毒就获得了免疫力,所以只有C项才符合第三段的内容。
    文中并没有提到得了感冒就胃疼,实际上文中根本就没有“stomachache”这个词或相关 的字眼,所以D项是正确答案。第二篇 本篇文章主要讲述了睡眠不足是现代美国社会的通病。分析了造成睡眠不足的一些原因, 以及睡眠不足产生的后果,建议人们增加睡眠以保持精力旺盛。
