(21) that logic, 2006 should have been a breakthrough year for rational behavior. With the memory of 9/11 still

    14、 (22) in their minds, Americans watched hurricane Katrina, the most expensive disaster in U.S. history, on (23) TV. Anyone who didnt know it before should have learned that bad things can happen. And they are made (24) worse by our willful blindness to risk as much as our (25) to work together befor

    16、ut a (28) of the past year in disaster history suggests that modern Americans are particularly bad at (29) themselves from guaranteed threats. We know more than we (30) did about the dangers we face. But it turns (31) that in times of crisis, our greatest enemy is (32) the storm, the quake or the (3

    24、 US is how friendly, courteous and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers ar

    25、e hardly unknown in the US. Yet it is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence.Dullness and loneliness were common problems of the families who generally lived

    26、 distant from one another. Strangers and travelers were welcome sources of diversion, and brought news of the outside world. The harsh realities of the frontier also shaped this tradition of hospitality.Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the near

    27、est cabin or settlement. It was not a matter of choice for the traveler or merely a charitable impulse on the part of the settlers. It reflected the harshness of daily life: if you didnt take in the stranger or take care of him, there was no one else who would. And someday, remember, you might be in

    28、 the same situation. Today there are many charitable organizations which specialize in helping the weary traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist trails. “I was just traveling th

    29、rough, got talking with this American, and pretty soon he invited me home for dinner-amazing. “ Such observations reported by visitors to the US are not uncommon, but are not always understood properly.The casual friendliness of many Americans should be interpreted neither as superficial nor as arti

    30、ficial, but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals, assumptions, and conventions underlies all social interrelationships. And, of course, speaking a language does not necessarily mean that someon

    31、e understands social and cultural patterns. Visitors who fail to “translate“ cultural meanings properly often draw wrong conclusions. For example, when an American uses the word “friend“, the cultural implications of the word may be quite different from those it has in the visitors language and cult

    32、ure. It takes more than a brief encounter on a bus to distinguish between courteous convention and individual interest. Yet, being friendly is a virtue that many Americans value highly and expect from both neighbors and strangers.(分数:5.00)(1).In the eyes of visitors from the outside world, _.A. rude

    33、 taxi drivers are rarely seen in the USB. small-minded officials deserve a serious commentC. Canadians are not so friendly as their neighboursD. most Americans are ready to offer help(分数:1.00)A.B.C.D.(2).It could be inferred from the last paragraph that _.A. culture exercises an influence over socia

    34、l interrelationshipB. courteous convention and individual interest are interrelatedC. various virtues manifest themselves exclusively among friendsD. social interrelationships equal the complex set of cultural conventions(分数:1.00)A.B.C.D.(3).Families in frontier settlements used to entertain strange

    35、rs _.A. to improve their hard lifeB. in view of their long-distance travelC. to add some flavor to their own daily lifeD. out of a charitable impulse(分数:1.00)A.B.C.D.(4).The tradition of hospitality to strangers _.A. tends to be superficial and artificialB. is generally well kept up in the united St

    36、atesC. is always understood properlyD. has something to do with the busy tourist trails(分数:1.00)A.B.C.D.(5).Whats the authors attitude toward Americans friendliness?A. Favorable.B. Unfavorable.C. Indifferent.D. Neutral.(分数:1.00)A.B.C.D.九、Text 2(总题数:1,分数:5.00)When prehistoric man arrived in new parts

    37、 of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.That the seas are being over fished ha

    38、s been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matte

    39、r) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start

    40、of exploitation. In some long-fished areas, it has halved again since then.Dr. Worm acknowledges that these figures are conservative. One reason for this is that fishing technology has improved. Todays vessels can find their prey using satellites and sonar, which were not available 50 years ago. Tha

    41、t means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not h

    42、ave been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewe

    43、r sharks around now.Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline. “ The notion is that people have failed to detect

    44、the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of i

    45、ts original levels. Most fisheries are well below that, which is a bad way to do business.(分数:5.00)(1).The extinction of large prehistoric animals is noted to suggest that _.A. large animals were vulnerable to the changing environmentB. small species survived as large animals disappearedC. large sea

    46、 animals may face the same threat todayD. slow-growing fishes outlive fast-growing ones(分数:1.00)A.B.C.D.(2).We can infer from Dr. Myers and Dr. Worms paper that _.A. the stock of large predators in some old fisheries has reduced by 90%B. there are only half as many fisheries as there were 15 years a

    47、goC. the catch sizes in new fisheries are only 20% of the original amountD. the number of larger predators dropped faster in new fisheries than in the old(分数:1.00)A.B.C.D.(3).By saying “these figures are conservative“ (Line 1, paragraph 3), Dr. Worm means that _.A. fishing technology has improved ra

    48、pidlyB. the catch sizes are actually smaller than recordedC. the marine biomass has suffered a greater lossD. the data collected so far are out of date(分数:1.00)A.B.C.D.(4).Dr. Myers and other researchers hold that _.A. people should look for a baseline that can work for a longer timeB. fisheries sho

    49、uld keep their yields below 50% of the biomassC. the ocean biomass should be restored to its original levelD. people should adjust the fishing baseline to the changing situation(分数:1.00)A.B.C.D.(5).The author seems to be mainly concerned with most fisheries _.A. management efficiencyB. biomass levelC. catch-size limitsD. technological appli
