8、在人们没有预料的地方冒出来。BDue to climate changes, Arctic ice is breaking up earlier in the spring, and its area is decreasing.This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.Polar bears off Alaska normally hunt and raise their young on ice sheets that float
9、 on the ocean.But as the ice has melted, the polar bears have been forced to spend more time on land.There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters.For polar bears, this food is less nutritious than seals that they normally catch on ice sheets.T
10、he shrinking (减少) ice has also forced more polar bears into the ocean.In the past, they only had to swim short distances between ice sheets.But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean.This poses a severe danger during rough weather, a
11、nd an increasing number of drowned polar bears have been observed.In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago.Polar bears on Hudson Bay fast (绝食) during the summer, waiting for ice to form in the fall to hunt.Every year, the summer gets longer, and
12、 the bears get skinnier.Over the past 25 years, the average weight of the female bears has dropped 68 kg.This loss affects their ability to reproduce, and already the number of births has dropped by 15 percent.Unless the bears can learn to survive these climate changes, these giants of the ice may o

15、life Journal. DDesign Magazine.【答案】本文讲述了气候变化对于北极熊的生存及繁殖带来的不利影响。4C细节理解题。根据第一段第一句话中的“Arctic ice is breaking up earlier in the spring ”可知，北极冰川每年春天较早时候就在融化。5B细节理解题。根据第二段可以看出北极熊正常情况下吃在冰面上可以捕捉到的海豹，但现在由于冰的减少，它们只能以当地猎人捕捉的鲸的残余物为食了。6A细节理解题。从最后一段第四和第五两句可知，北极熊的出生率已经下降了15%。7C文章出处题。通读全篇，可以发现文章叙述的是全球气候的变化给北极熊带来的负面
16、影响，而北极熊属于野生动物，所以推断这篇文章最有可能摘自野生动物杂志。CIn the atmosphere, carbon dioxide allows the suns rays to enter but prevents the heat from escaping.According to a weather experts prediction, the atmosphere will be warmer in the year 2050 than it is today, if man continues to burn fuel at the present rate.If thi
17、s warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities.Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere.In the past, concern about a manmade
18、warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that wi
19、ll possibly take place in the next fifty years from the burning of fuels.Satellite pictures show that large areas of Antarctic ice are already disappearing.The evidence suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.However, most of the fuel is burnt
20、 in the northern part of the earth, where temperatures seem to be falling.Scientists conclude, therefore, that up to now natural influences on the weather have exceeded those caused by man.The question is: Which natural cause has the most effect on the weather?One possibility is the behavior of the
21、sun.Astronomers at one research station have studied the hot spots and “cold” spots, that is, the relatively less hot spots, on the sun.This seems to have a greater effect on the distribution of the earths atmospheric pressure, and consequently on wind circulation.The sun is also variable over a lon
22、g term.Its heat output goes up and down in cycles.The latest trend being downward is on the way.But that is only an imagination.8The carbon dioxide in the atmosphere would _.Aprevent the suns rays from reaching the earths surfaceBmean a warming up in the ArcticCaccount for great changes in the clima
23、teDraise the temperature of the earths surface9The article was written to explain _.Athe greenhouse effectsBthe solar effects on the earthCthe solar weatherDthe causes affecting weather10Although the fuel is greater in the northern part, temperatures there seem to be falling. This is _.Amainly becau
24、se the carbon dioxide is risingBpossibly because the ice caps in the poles are meltingCdue to the effect of the earths climateDpossibly due to the activity of the sun11What does the underlined word “exceeded” mean?ATo be the same as.BTo be slower than.CTo be better than. DTo be bigger than.【答案】本文讲述的
25、是影响天气变化的诸多原因，包括人类活动和太阳运动。8D细节理解题。文章第一段讲到二氧化碳在大气中吸收太阳的光线并阻挡光热的流失，文章第二段最后一句话又再次提到二氧化碳能使地球变热的理论。因此，答案为D项。9D目的意图题。全文讲述的是影响天气的诸多原因。选项A、B、C在文中均被提及但不足以概括全文的主旨，只有D项是比较全面的。10D细节理解题。文章第三段提及这一现象时讲到，科学家们认为：这一现象的产生是因为到目前为止自然界对天气的影响要大于人类对天气的影响。而究竟是哪种自然力量对天气的影响最大呢？文章第四段第一句话给出了答案：其中一个可能就是太阳的活动。D项与此意相符。11D词义猜测题。由倒数第
26、一段的“This seems to have a greater effect on the distribution of the earths atmospheric pressure, and consequently on wind circulation (循环)”可看出，自然界对天气的影响要大于人类对天气的影响。DAs you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and
27、 a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.Now, perhaps,
28、more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the_long_hours_work_culture_to_make_more_money_is_eating_up_their_lives,_leaving them very little time or
29、energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them. Six percent of workers in Britain took the decision to downshift last year.One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she u
30、sed to work for an international bank. They would go to work by train every day from their large house in the suburbs, leaving their two children with a nanny. Most evenings Daniel wouldnt get home until eight or nine oclock and nearly twice a month he would have to fly to New York for meetings. The
31、y both earned a large amount of money but began to feel that life was passing them by.Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm then，” says Daniel, “and we took almost a year to make the decision to downshift. Its taken some getting used to, but its been wo
32、rth it. We have to think twice now about spending money on car repairs and we no longer have any holidays.However, I think its made us stronger as a family, and the children are a lot happier.”Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. Im n
33、ot really a country girl, but I suppose Im gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much or you might not do it at all.”12The passage tell
34、s us that_.Apeople seldom work long hours to make moneyBpeople hardly buy more things than necessaryCpeople are sure everything they own is in the right placeDpeople realize there is more to life than just making money13When Daniel was a reporter he _.Alived in central LondonBdisliked his jobCmissed
35、 his childrenDwas well paid14Daniel and Liz both agree that the move to the farm _.Awas easy to organizeBhas improved family lifeCwas extremely expensiveDhas been a total success15What does the author mean by saying “the long hours work culture to make more money is eating up their lives” in the sec
36、ond paragraph?APeople work long hours to earn their living.BTo make more money through hard work is the aim of peoples life.CLong hours of hard work occupy too much of peoples life.DPeople spent too much time and money eating meals.【答案】12D主旨大意题。第一段描述了一番景象，家里很富裕，几乎什么都不缺；第二段却话题一转，说“people are wonderin
37、g what life is all about”，说明物质的追求让人们感到生活的乏味，再有“leaving them very little time or energy for family or pastimes”，从而说明了生活中除了挣钱，还有很多东西值得去追求。故选D。13D细节理解题。第三段最后一句话说明当Daniel 是一名记者时，他的工资很高。答案为D。14B细节理解题。从第四段和第五段可知，Daniel和Liz搬到农场后家庭生活发生了可喜的变化。15C句义猜测题。结合文意可知，划线的部分是指“长时间工作赚钱的文化荒废了他们的家庭生活”与C项意义接近，故选C项。第二节(共5小题
