Section BDirections: There are 2 passages in this ction. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
The news about the world’s oceans in 2003 wasn’t that they’re in trouble — that much was already clear — but that the scale of devastation is far greater than anyone had realized. A shocking study revealed that a full 90 percent of the species most desirable to fishmongers(鱼商)—tuna, halibut, sharks, swordfish, grouper — has been wiped out in the past half century. But there was hopeful news as well. An alternative to conventional fishing practices, while not a cure-all(万灵药), could significantly restore ravaged fish populations. The chilling centerpiece of last year’s marine rearch: just 50 years of indus
tube stationtrial fishing has decimated(大批杀害)the world’s large predator(食肉动物)fish species, according to a report published in Nature in May. Irresponsible fishing practices have resulted vere casualties: Shrimp trawling(拖网捕捞)in the Gulf of Mexico, for example, a reckless process in which, for every ton of shrimp obtained, three tons of fin-fish(长须鲸)are destroyed and discarded — has shrunk large fish stocks a thousandfold. “Across the board we’ve removed everything bigger than a bicycle from the o-cean,” says Steve Palumbi, a Stanford University biologist, “and that has almost certainly changed the ocean in fundamental ways. “ But the urgent need for large-scale conrvation efforts is on a collision cour with economic pressures to expand fishing even further, according to a 2003 report by the Pew Oceans Commission, an independent expert panel, as well as preliminary reports from members of the Bush-appointed U. S. commission on Ocean Policy. Americans are eating more afood than ever: Consumption was up 7 percent in 2002, to 4. 5 billion pounds. Worldwide, more than 130 billion pounds of marine species are caught annually, and that doesn’t include the huge amount of a life destroyed as by-catch. More than a billion people rely on fish for protein. “ We need to change the whol
e ethic of how we are viewing the oceans,” says Andrew Ronberg, a member of the Commission on Ocean Policy, “ from a place that we u to a place we care for. “ In September marine biologists Fiona Gell and Callum Roberts of the University of York in England offered a solution, boldly asrting that at least 30 percent of the world’s ocean habitat had to become safe zones for marine life. It’s a practical, not a ntimental matter, they contend. After studying 60 no-fishing zones around the world, Gell and Roberts discovered that the fish there live longer, grow larger, and produce more young than tho in unprotected areas. Significantly, as populations growing, many fish head into less crowded areas outside the rerve, where fishermen reap the benefits indefinitely. “It’s a no-brainer(无需用脑的事), really, isn’t it?” Roberts obrves. “Like money in the bank producing interest. “
1． Whatbutt苍耳的拼音’s the news about the oceans in 2003?
A．People ignore what the oceans are suffering.
B．The scale of the ocean devastation is out of our expectation.
shortcutC．The fishmongers are making effort to improve their fishing practices.
D．The oceans are losing many rare species.
厉害英语正确答案：B
解析：事实细节题。第一段首句用了一个not…but句型，重点在but后面，指出2003年有关海洋的消息，不是海洋处于危险的境地，而是其破坏程度远比任何人已经意识到的还要严重。由此看出海洋受到破坏的程度超过了人们的预料，[B]项正确。人们不是忽视了而是低估了海洋的受破坏的程度，[A]项错误。[C]项文中未提及，[D]项是程度严重的一个方面，不能概括2003年一年的内容，故也排除。 知识模块：篇章阅读
2． What is the alternative to conventional fishing practices according to the passage?
A．Setting up an ocean rerve which bans heavy fishing.
B．Banning and opening fishing by turning around the world.
C．Limiting the total amount of fishing of all the countries.
D．Setting up more no-fishing zones around the world.
正确答案：D
解析：推理判断题。第一段末句提到有一种替代传统捕捞的方式让人们看到了希望。最后一段中提到了这种方式，即罗伯茨他们提到的把至少30％的海洋划为海洋生物安全区(safe zones for marine life)。下文中又提到了安全区的另一种说法：no-fishing zones。显然目前的禁渔区是不够的，罗伯茨的方法就是[D]“在世界上建立更多的禁渔区”。故[D]项为答案。禁渔区本来就有，所以[A]不对。其他两项文中没有提及。 知识模块：篇章阅读
3． The author mentions America’s increasing afood consumption to show______.
A．the different life styles the Americans haveblock什么意思
B．U. S. should be blamed for the devastation of oceans
C．how high the economic pressures on ocean rerves are
D．the great influence of human life on natural surroundings
线上线下作文正确答案：C
解析：推理判断题。第三段中举出美国人消耗海产品的巨大数量，是为了说明前文中的“大规模保护工作的迫切需要与进一步扩大捕鱼业的经济压力是互相冲突的”这一观点的，正确的是[C]“彰显经济对海洋保护的巨大压力”。 知识模块：篇章阅读
4． Why are finfish destroyed in the process of shrimp trawling in the Gulf of Mexico?
A．They are by-catch.
B．They are dangerous.
C．They grow too big.
D．They have no economic value.
正确答案：A
解析：事实细节题。第二段中说墨西哥的拖网捕虾中会把捕到的长须鲸杀死并扔掉。显然长须鲸不是渔民们的捕捞目标，才会被毁掉。第三段第三句中用一个名词来表示这种不是捕捞目标而被捕捞到的渔获，就是by—catch。所以[A]项为答案。 知识模块：篇章阅读
5． What does Roberts mean by “ Like money in the bank producing interest”(Line 9, Para. 4)?
A．Fish of outside the rerve don’t meet the need.
B．The rerve will surely benefit fishermen.
C．Marine life is of great worth, as money in bank.
D．We should love marine species as money.
正确答案：B
解析：语义理解题。罗伯茨说“就象钱存入银行产生利息一样”，显然是为了说明建立保护区的好处。正确的是[B]。 知识模块：篇章阅读
Would some degree of warming be bad for most societies and natural environments? “During the 20th century, province“外交部翻译美女 writes Dr. Patrick Michaels, “we have already proceeded more than half way to doubling the natural carbon dioxide greenhou effect. Here is what resulted: Life expectancy doubled in the free and developed world. The developing world is catching up as their emissions ri. Corn production peracre incread fivefold. The growing ason in the coldest latitudes incread slightly, but enough to increa greenness by 10 percent. “ The small amount of warming that occurred during the past century consisted primarily of incread minimum temperatures at night and during winters. This means higher average temperatures, should they occur, would not result in more daytime evaporation, which some claim would lead to droughts and dertification. Warmer winters would mean longer growing asons and less stress on most plants and wildlife, producing a substantial benefit for the global ecosystem. Finally, past warming has been accompanied by incread cloudiness, a phenomenon also predicted by most global climate models. This means a warmer world would probably be a wetter world, which once again would be beneficial to most plant and animal life. Ex-Vice President A
l Gore claimed that “ hundreds of millions of people may well become even more susceptible to the spread of dias when populations of pests, germs, and virus migrate with the changing climate patterns”. Gore has also claimed that global warming will cau floods, droughts, heavy rainfall, forest fires, retreating glaciers, and heavier snowfall. In addition to often being at odds with each other, Gore’s claims are at odds with most scientific rearch. The two historical epidemics described by Gore to validate his prediction were unrelated to climate change. The Black Death, for example, was transmitted by rats, which flourish in cool as well as warm climates. Cholera has been a threat in warm as well as cold climates, and is readily brought under control by treating water supplies with chlorine(氯). The latest rearch suggests that a levels would decline, not ri, if temperatures ri, due to incread evaporation from the oceans and subquent precipitation over land. Increasing polar temperatures by a few degrees would not cau ice or snow to melt becau the original temperatures are so low that an increa of a few degrees would leave them well below freezing. The IPCC itlf found “ inadequate data to determine whether consistent global changes in climate variability or
weather extremes have occurred over the 20th century,” with some regions exhibiting greater variability and others less. In short, a slightly warmer world would probably be greener and a little cloudier than our world today, but otherwi not much different.
6． What’s Dr. Patrick Michaels’ opinion towards global warming?
A．It can prolong the grow ason in the low latitudes.机械管理
B．It will shorten people’s life span.
C．Some degree of it can benefit human.
D．Some degree of it can cau a reduction in grain yield.
正确答案：C
解析：观点态度题。第一段Here is what result后全部是Patrick Michaels对一定程度的全球
变暖造成的影响的观点：人们的平均寿命延长，作物增产，最冷的纬度地区的种植季节有所延长。故可以看出他认为一定程度的全球变暖是会有益于人类的，[C]项是对文意的正确理解，故为答案。文中说最冷纬度地区的种植季节可以增加，根据常识判断最冷纬度区应该在高纬度区，而非低纬度区，故[A]项错误。[B]、[D]正好与文意相反，故也都排除。 知识模块：篇章阅读
7． The author may didn’t agree that the temperature ri can result in______.
A．a-level change
B．droughts and decertification
C．the promotion of food production
D．longer growing asons
正确答案：B
解析：推理判断题。文章第二段第二句提到平均气温的升高不会产生像有些人声称的将会
导致白天水分更多的蒸发，继而导致干旱和沙漠化，所以可判断选项[B]为本题答案。选项[A]、[C]、[D]都是作者的观点。 知识模块：篇章阅读
