1、Britain\'s Solo SailorEllen MacArthur started sailing when she was eight, going out on sailing trips with her aunt. She loved it so much that she saved her money for three years to buy her first small sailing boat. When she was 18, she sailed alone around Britain and won the "Young Sailor of the Year" award.Ellen became famous in 2001. Aged only 24, she was one of the only two women who entered the Vendee Globe round the world solo race, which lasts 100 days. Despite of many problems, she came the second in the race out of 24 competitors and she was given a very warm welcome when she returned.Ambition and determination have always been a big part of Ellen\'s personality. When she was younger, she lived in a kind of hut (棚屋) for three years while she was trying to get sponsorship to compete in a transatlantic race. Then she took a one - way ticket to France, bought a tiny seven meter Class Mini yacht (游艇), slept under it while she was repairing it, and then she raced it 4,000 kilometres across the Atlantic in 1997, alone for 33 days.Ellen has to learn many things, because sailing single - handed means that she has to be her own captain, electrician, sailmaker, engineer, doctor, journalist, cameraman and cooker, She also has to be very fit, and because of the dangers of sleeping for long periods of time she\'s in the middle of the ocean, she has trained herself to sleep for about 20 minutes at a time.And she needs courage. Once, in the middle of the ocean, she had to climb the mast (桅杆) of a boat to repair the sails at four o\'clock in the morning, with 100 kph winds blowing around her. It took her many hours to make the repairs, Ellen says: "I was exhausted when came down. It\'s hard to describe how it feels to be up there. It\'s like trying to hold onto a big pole, which for me is just too big to get my arms around, with someone kicking you all the time and trying to shake you off".But in her diary, Ellen also describes moments which is worthwhile (值得的) :"A beautiful sunrise started the day, with black clouds slowly lit by the bright yellow sun. I have a very strong feeling of pleasure, being out here on the ocean and having the chance to live this. I just feel lucky to be here."According to paragraph 4, which of the following statements is NOT true? ____ 【单选题】

A.She has to learn to repair sails.

B.She has to be her own teacher.

C.She has to be very fit.

D.She has trained herself to sleep for about 20 minutes at a time.

正确答案:B

答案解析:本题是判断题，有一定难度，选项的干扰较大，需要确定好文章里sailmaker的意思，需要紧扣文章原意。选项里A，B干扰较大，因为，C，D很明显是文章里明确提到的，可以排除。第四段谈到，“Ellen必须学会许多事情，因为单独航行意味着她必须是自己的船长、电工、修帆工……”Sailmaker是指“修船工”，所以A的意思和原文是一致的，可以排除。Captain，船长，不是教师，所以B是错误的，答案是B。

2、Woman workThough some people have suggested that women should return to housework in order to leave more jobs for men, the idea has been rejected by both women and men in public opinion polls.Lately some union officials have suggested that too many women are employed in types of work more suitable for men and that women should step aside to make way for unemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development and result in productivity, poor quality and inefficiency.To solve the problem, they suggested that working women stay at home while their husbands or brothers were given double wages. They argue that under these circumstances, families would remain their same level of income, and women could run the house and raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people polled .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant and stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their ____ salary and be allowed to return to work after the three-year period. This will benefit children, women, their families and the society and it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

A.common

B.ordinary

C.normal

D.real

正确答案:C

答案解析:该句的意思是“休假期间可以得到正常工资的75%，三年后回来继续上班”。common、 ordinary是“普通的、一般的”要排除。real是真正的，不符合作者的意思。

3、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight or shade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science for well-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun and colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell and Wieman, have successfully cooled down a gas temperature barely above absolute zero. They won a Nobel Prize in Physics in 2001 for their work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize _____ behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.will

B.would

C.must

D.can

正确答案:B

答案解析:本句的主句中的谓语动词用的是过去时helped，根据“主句为过去时态，宾语从句一般也要用过去时态”这一时态一致原则，本题要选would。

4、Ceasing to Wear TiesIt\'s useless. It\'s dirty. It spreads disease. That\'s why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.That leads to another question. Why does anyone wear a tie? Ties serve no purpose. They do not cover any part of your body and keep you warm. They always seem to get covered in food stains. Perhaps that is the purpose of the tie. It lets everyone know what you just ate.Ties have an odd history. Soldiers from Croatia, in Eastern Europe, served as mercenaries (雇佣军) in various conflicts in the 17th century. They were identified by brightly colored pieces of silk worn around the neck. Known as cravats(围巾), these became a popular fashion item in France and eventually evolved into the tie.It\'s an interesting story, but it doesn\'t tell us why men want to put useless pieces of cloth or silk around their necks. The answer seems to be about identification(身份证明 ). In the 19th-century Britain, ties were used by universities, military regiments (团), sports clubs, schools and gentleman\'s clubs. Each tie was in a particular set of colors which identified the wearer as a member of that organization. Wearing ties was also the mark of Britain\'s most powerful classes. That made the tie itself a symbol of power and respect. And that led it to be adopted by a much larger class-the business class.You cannot wear a tie if you work with machinery, so wearing a tie became a sign that you were a man who used his brain to make a living, rather than his hands. It showed you were serious. It showed you were a professional. It meant that everyone who wanted a job in business had to wear one. It was just impossible to take seriously a man who did not wear a piece of colored silk around his neck. This is how millions of people came to wear ties across the world.Is there a future for ties? The signs are not promising. Many political leaders, including British Prime Minister Tony Blair, now go without ties.The British Medical Association suggested that________.【单选题】

A.they were workmen

B.they were members of different organizations

C.hospital doctors stop wearing ties

D.who does not always wear a tie

E.who served as mercenaries in many conflicts in the 17th century

F.who does not want to live like a king

正确答案:C

答案解析:根据题干中的线索词British Medical Association可定位到第一段最后一句：That\'s why the British Medical Association in the UK recently called for hospital doctors to stop wearing ties.选项C与其表达吻合，是原文的原意复现，故C为正确答案。

5、Geology and Heap(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.Paragraph 3 ______【单选题】

A.No Evidence to Indicate Bad of Naturally Contaminated Soil

B.Potential Hazards of Human Contaminated Soils

C.Research an Channels of Heavy Metals Getting into Human Food Chain

D.Geology and Health Problems

E.Rocks----the Ultimate Source of Soil Pollution

F.Long-term Health Effects on Children

正确答案:A

答案解析:第3段谈及的是自然污染的土壤一般情况下对人体不会造成危害。此段首句就提示了这一点： So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard.
