　　Television Is Doing Irrearable Harm

　　“Yes, but what did we use to do before there was television?” How often we hear statements like this! Television hasn't been with us all that long, but we are already beginning to forget what the world was like without it, Before we admitted the one-eyed monster into our homes we never found it difficult to occupy our spare time. We used to enjoy civilized pleasures. For instance, we used to have hobbies, we used to entertain our friends and be entertained by them, we used to go outside for our amusements to theatres, cinemas, restaurants and sporting events, We even used to read books and listen to music and broadcast talks occasionally. All that belongs to the past. Now all our free time is regulated by the “goggle box”. We rush home or gulp down our meals to be in time for this or that programme. We have even given up sitting at table and having a leisurely evening meal, exchanging the news of the day. A sandwich and a glass of beer will do anything, providing it doesn't interfere with the programme. The monster demands absolute silence and attention. If any member of the family dares to open his mouth during a programme, he is quickly silenced.

　　Whole generation are growing up addicted to the telly. Food is left uneaten, homework undone and sleep is lost, The telly is a universal pacifier. It is now standard practice for mother to keep the children quiet by putting them in the living room and turning on the set. It doesn't mater that the children will watch rubbishy commercials or spectacles of sadism(性虐狂)and violence—so long as they are quiet.

　　There is a limit to the amount of creative talent available in the world, Every day, television consumes vast quantities of creative work, That is why most of the programmes are so bad：it is impossible to keep pace with the demand maintain high standards as well. When millions watch the same programme, the whole world becomes a village, and society is reduced to the conditions which obtain in pre-literate communities (有文字之前的時期 ). We become utterly dependent on the two most primitive media of communication: pictures and the spoken work.

　　Television encourages passive enjoyment. We become content with second-hand experiences. It is so easy to sit in our armchair watching others working. Little by little “television” cuts us off from the real world. We get so lazy, we choose to spend a fine day in semi-darkness, glued to our sets, rather than go out into the world itself, Television may be a splendid medium of communication, but it prevents us from communicating with each other. We only become aware how totally irrelevant television is to real living when we spend a holiday by the sea or in the mountains, far away from civilization, In quiet natural surroundings we quickly discover how little we miss the hypnotic (催眠)tyranny of King Telly.

　　Screen Test

　　1　Every year millions of women are screened with X-rays to pick up signs of breast cancer. If this happens early enough, the disease can often be treated successfully. According to a survey Australia, Canada, the US and Spain, screen women under 50.

　　2　But the medical benefits of screening these younger women are controversial, partly because the radiation brings a small risk of inducing cancer. Also, younger women must be given higher doses of X-rays because their breast tissue is denser.

　　3　Researchers at the Polytechnic University of Valencia analysed the effect of screening more than 160,000 women at 11 local clinics. After estimating the women's cumulative dose of radiation, they used two models to calculate the number of extra cancers this would cause.

　　4　The mathematical model recommended by Britain's National Radiological Protection Board (NRPB) predicted that the screening programme would cause 36 cancers per 100,000 women, 18 of them fatal. The model preferred by the UN Scientific Committee on the Effects of Atomic Radiation led to a lower figure of 20 cancers.

　　5　The researchers argue that the level of radiation-induced cancers is “not very significant” compared to the far larger number of cancers that are discovered and treated. The Valencia programme, they say, detects between 300 and 450 cases of breast cancer in every 100,000 women screened.

　　6　But they point out that the risk of women contracting cancer from radiation could be reduced by between 40 and 80 percent if screening began at 50 instead of 45, because they would be exposed to less radiation. The results of their study, they suggest, could help “optimize the technique” for breast cancer screening.

　　7 　“There is a trade-off between the diagnostic benefits of breast screening and its risks,” admits Michael Clark of the NRPB. But he warns that the study should be interpreted with caution. “On the basis of the current data, for every 10 cancers successfully detected and prevented there is a risk of causing one later in life. That's why radiation exposure should be minimized in any screening programme.”

　　23　Paragraph 2 ___________

　　24　Paragraph 3 ___________

　　25　Paragraph 4 ___________

　　26　Paragraph 5 ___________ A　Harm Screening May Do to a Younger Woman

　　B　Investing the Effect of Screening

　　C　Effects Predicted by Two Different Models

　　D　Small Risk of Inducing Cancers from Radiation

　　E　Treatment of Cancers

　　F　Factors That Trigger Cancers

　　27　Early discovery of breast cancer may ___________.

　　28　Advantages of screening women under 50 are ___________.

　　29　Delaying the age at which screening starts may ___________.

　　30　Radiation exposure should be ___________.

　　A　be costly

　　B　harmful

　　C　save a life

　　D　still open to debate

　　E　reduce the risk of radiation triggering a cancer

　　F　reduced to the minimum

　　第4部分：閱讀理解(第31——45題，每題3分，共45分)

　　下面有3篇短文，每篇短文后有5道題，每題后面有4個選項。請仔細閱讀短文并根據(jù)短文回答其后面的問題，從4個選項中選擇1個最佳答案涂在答題卡相應的位置上。

　　第一篇

　　Putting Plants to Work

　　Using the power of the sun is nothing new. People have had solar-powered calculators and buildings with solar panels for decades. But plants are the real experts: They've been using sunlight as an energy source for billions of years.

　　Cells in the green leaves of plants work like tiny factories to convert sunlight, carbon dioxide, and water into sugars and starches, stored energy that the plants can use. This conversion process is called photosynthesis. Unfortunately, unless you're a plant, it's difficult and expensive to convert sunlight into storable energy. That's why scientists are taking a closer look at exactly how plants do it.

　　Some scientists are trying to get plants, or biological cells that act like plants, to work as miniature photosynthetic power stations. For example, Maria Ghirardi of the National Renewable Energy Laboratory in Golden, Colo., is working with green algae. She's trying to trick them into producing hydrogen instead of sugars when they perform photosynthesis. Once the researchers can get the algae working efficiently, the hydrogen that they produce could be used to power fuel cells in cars or to generate electricity.

　　The algae are grown in narrow-necked glass bottles to produce hydrogen in the lab. During photosynthesis, plants normally make sugars or starches. “But under certain conditions, a lot of algae are able to use the sunlight energy not to store starch, but to make hydrogen.” Ghirardi says. For example, algae will produce hydrogen in an airfree environment. It's the oxygen in the air that prevents algae from making hydrogen most of the time. Working in an airfree environment, however, is difficult. It's not a practical way to produce cheap energy. But Ghirardi and her colleagues have discovered that by removing a chemical called sulfate from the environment that the algae grow in, they will make hydrogen instead of sugars, even when air is present.

　　Unfortunately, removing the sulfate also makes the algae's cells work very slowly, and not much hydrogen is produced. Still, the researchers see this as a first step in their goal to produce hydrogen efficiently from algae. With more work, they may be able to speed the cells' activity and produce larger quantities of hydrogen.

　　The researchers hope that algae will one day be an easy-to-use fuel source. The organisms are cheap to get and to feed, Ghirardi says, and they can grow almost anywhere: “You can grow them in a reactor, in a pond. You can grow them in the ocean. There's a lot of flexibility in how you can use these organisms. ”

　　31　What does the writer Say about plants concerning solar energy?_______

　　A　Plants are the real experts in producing solar energy.

　　B　Plants have been used to produce solar energy.

　　C　Plants have been using solar energy for billions of years.

　　D　Plants have been a source of solar energy.

　　32Why do some scientists study how plants convert sunlight carbon dioxide, and water into sugars and starches? _______

　　A　Because they want algae to produce sugars and starches.

　　B　Because they want green plants to become a new source of energy.

　　C　Because they want to turn plant sugars to a new form of energy.

　　D　Because they want to make photosynthesis more efficient.

　　33　According to the fifth paragraph, under what conditions are algae able to use solar energy to make hydrogen? _______

　　A　When there is a lot of oxygen in the air.

　　B　When there is no oxygen in the air.

　　C　When photosynthesis is taking place.

　　D　When enough starch is stored.

　　34　Researchers have met with difficulties when trying to make algae produce hydrogen efficiently. Which one of the following is one such difficulty? _______

　　A　It is not possible to remove sulfate from the environment.

　　B　It is not possible to work in an airfree environment to produce hydrogen.

　　C　It is not easy to make sugars instead of hydrogen.

　　D　It is too slow for algae to produce hydrogen when the sulfate is removed.

　　35　What is NOT true of algae _______

　　A　They are easy to grow.

　　B　They can be a very good fuel source.

　　C　They are cheap to eat.

　　D　They can be used in many ways.

　　第二篇

　　Human Ingenuity

　　Since the dawn of human ingenuity, people have devised ever more cunning tools to cope with work that is dangerous, boring, burdensome, or just plain nasty. That compulsion has resulted in robotics—the science of conferring various human capabilities on machines. And if scientists have yet to create the mechanical version of science fiction, they have begun to come close.

　　As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms. Our banking is done at automated teller terminals that thank us with mechanical politeness for the transaction. Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracy—far greater precision that highly skilled physicians can achieve with their hands alone.

　　But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselves—goals that pose a real challenge. “While we know how to tell a robot to handle a specific error,” says Dave Lavery, manager of a robotics program at NASA, “we can't yet give a robot enough ' common sense' to reliably interact with a dynamic world. ”

　　Indeed the quest for true artificial intelligence has produced very mixed results. Despite a spell of initial optimism in the 1960s and 1970s when it appeared that transistor circuits and microprocessors might be able to copy the action of the human brain by the year 2010, researchers lately have begun to extend that forecast by decades if not centuries.

　　What they found, in attempting to model thought, is that the human brain's roughly one hundred billion nerve cells are much more talented—and human perception far more complicated—than previously imagined. They have built robots that can recognize the error of a machine panel by a fraction of a millimeter in a controlled factory environment. But the human mind can glimpse a rapidly changing scene and immediately disregard the 98 percent that is irrelevant, instantaneously focusing on the monkey at the side of winding forest road or the single suspicious face in a big crowd. The most advanced computer systems on Earth can't approach that kind of ability, and neuroscientists still don't know quite how we do it.

　　36　Human ingenuity was initially demonstrated in _______.

　　A　the use of machines to produce science fiction

　　B　the wide use of machines in manufacturing industry

　　C　the invention of tools for difficult and dangerous work

　　D　the elite's cunning tackling of dangerous and boring work

　　37　The word “gizmos” (line 1, paragraph 2) most probably means _______.

　　A　programs

　　B　experts

　　C　devices

　　D　creatures

　　38 　According to the text, what is beyond man's ability now is to design a robot that can _______.

　　A　fulfill delicate tasks like performing brain surgery

　　B　interact with human beings verbally

　　C　have a little common sense

　　D　respond independently to a changing world

　　39　Besides reducing human labor, robots can also _________.

　　A　make a few decisions for themselves

　　B　deal with some errors with human intervention

　　C　improve factory environments

　　D　cultivate human creativity

　　40　The author uses the example of a monkey to argue that robots are _________.

　　A　expected to copy human brain in internal structure

　　B　able to perceive abnormalities immediately

　　C　far less able than human brain in focusing on relevant information

　　D　best used in a controlled environment

　　第三篇

　　The Rising Oil Price

　　Could the bad old days of economic decline be about to return? Since OPEC agreed to supply-cuts in March, the price of crude oil has jumped to almost $ 26 a barrel, up from less than $10 last December. This near-tripling of oil prices calls up scary memories of the 1973 oil shocks resulted in double-digit inflation and global economic decline. So where are the headlines warning of gloom and doom this time?

　　The oil price was given another push up this week when Iraq suspended oil exports. Strengthening economic growth, at the dame time as winter grips the northern hemisphere, could push the price higher still in the short term.

　　Yet there are good reasons to expect the economic consequences now to be less severe than in the 1970s. In most countries the cost of crude oil now accounts for a smaller share of the price of petrol than it did in the 1970s. In Europe, taxes account for up to four-fifths of the retail price, so even quite big changes in the price of crude have a more muted effect on pump prices than in the past.

　　Rich economics are also less dependent on oil than they were, and so less sensitive to swings in the oil price. Energy conservation, a shift to other fuels and a decline in the importance of heavy, energy-intensive industries have reduced oil consumption. Software, consultancy and mobile telephones use far less oil than steel or car production.For each dollar of GDP(in constant prices)rich economics now use nearly 50%less oil than in 1973.The OECD estimates in its latest Economic Outlook that。if oil prices averaged$2 2 a barrel for a full year，compared with$13 in l998。this would increase the oil import bill in rich economies by only 0.25%——0.5%of GDP.That is less than one-quarter of the income loss in l974 0r 1980.On the other hand，oilimporting emerging economies--to which heavy industry has shifted--have become more energy-intensive，and SO could be more seriously squeezed.

　　One more reason not to lose sleep over the rise in oil prices is that，unlike the rises in the 1970s，it has not occurred against the background of general commodity-price inflation and global excess demand.A sizable portion of the world is only just emerging from economic decline.The Economist’s commodity price index is broadly unchanging from a year a90.In 1973 commodity prices jumped by 70%，and in l979 by almost 30%.

　　41 The main reason for the latest rise of oil price is _________.

　　A　global inflation

　　B　reduction in supply

　　C　fast growth in economy

　　D　Iraq’s suspension of exports

　　42　It can be inferred from the text that the retail price of petrol will go up dramatically if _______.

　　A　price of crude rises

　　B　commodity prices rise

　　C　consumption rises

　　D　oil taxes rise

　　43　The estimates in Economic Outlook show that in rich countries _______.

　　A　heavy industry becomes more energy-intensive

　　B　income loss mainly results from fluctuating crude oil prices

　　C　manufacturing industry has been seriously squeezed

　　D　oil price changes have no significant impact on GDP

　　44　We can draw a conclusion from the text that _______.

　　A　oil—price shocks are less shocking now

　　B　inflation seems irrelevant to oil-price shocks

　　C　energy conservation can keep down the oil prices

　　D　the price rise of crude leads to the shrinking of heavy industry

　　45　From the text we can see that the writer seems _______.

　　A　optimistic

　　B　sensitive

　　C　gloomy

　　D　scared

　　Looking to the Future

　　When a magazine for high-school students asked its readers what life would be like in twenty years, they said: Machines would be run by solar power. Buildings would rotate so they could follow the sun to take maximum advantage of its light and heat. Walls would “radiate light” and “change color with the push of a button.” Food would be replaced by pills. School would be taught “by electrical impulse while we sleep.” Cars would have radar. Does this sound like the year 2000? Actually, 46 and the question was, “what will life be like in 1978?”

　　The future is much too important to simply guess about, the way the high school students did, so experts are regularly asked to predict accurately. By carefully studying the present skilled businessmen, scientists, and politicians are supposedly able to figure out in advance what will happen. But can they? One expert on cities wrote: 47, but would have space for farms and fields. People would travel to work in “airbuses”, large all-weather helicopters carrying up to 200 passengers. When a person left the airbus station he could drive a coin-operated car equipped with radar. The radar equipment of cars would make traffic accidents “almost unheard of”. Does that sound familiar? If the expert had been accurate it would, because he was writing in 1957. His subject was “The city of 1982.”

　　If the professionals sometimes sound like high-school students, it's probably because 48 But economic forecasting, or predicting what the economy will do, has been around for a long time. It should be accurate, and generally it is. But there have been some big mistakes in this field, too. In early 1929, most forecasters saw an excellent future for the stock market. In October of that year, 49, ruining thousands of investors who had put their faith in financial foreseers.

　　One forecaster knew that predictions about the future would always be subject to significant errors. In 1957, H. J. Rand of the Rand Corporation was asked about the year 2000, “Only one thing is certain,” he answered. “Children born today 50.”

　　A　the stock market had its worst losses ever

　　B　will have reached the age of 43

　　C　the article was written in 1958

　　D　Cities of the future would not be crowded

　　E　the prediction of the future is generally accurate

　　F　future study is still a new field

　　Wonder Webs

　　Spider webs are more than homes, and they are ingenious traps. And the world's best webspinner may be the Goldern Orb Weaver spider. The female Orb Weaver spins a web of fibers thin enough to be invisible to insect prey, yet 51 enough to snare a flying bird without breaking.

　　The secret of the web's strength? A type of super-resilient 52 called dragline. When the female spider is ready to 53 the web's spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly. Dragline is not sticky, so the spider can race back and forth along 54 to spin the web's trademark spiral.

　　Unlike some spiders that weave a new web every day, a Golden Orb Weaver 55 her handiwork until it falls apart, sometimes not for two yearsl. The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than Kevlar, a high-strength human-made 56 used in bullet-proof vests. And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original 57 and snap back as well as well as new. No human-made fiber even comes 58

　　It is no 59 manufacturers are clamoring for spider silk. In the consumer pipeline: high-performance fabrics for athletes and stockings that never run. Think parachute cords and suspension bridge cables. A steady 60 of spider silk would be worth billions of dollars-but how to produce it? Harvesting silk on spider farms does not 61 because the territorial arthropods have a tendency to devour their neighbors.

　　Now, scientists at the biotechnology Nexia are apinning artificial silk modeled after Goldern orb dragline. The 62 step: extract silk-making genes from the spiders. Next, implant the genes into goat egg cells. The nanny goats that grown from the eggs secrete dragline silk proteins in their 63 "The young goats pass on the silk-making gene without 64 help from us," says Nexia president Jeffrey Turner. Nexia is still perfecting the spinning process, but they hope artificial spider silk will soon be snagging customers 65 the real thing snags bugs.

　　22　A文章最后一段提到：we get so lazy…;it prevents US from communicating with each other說明人們因為電視變得懶惰和低能。

　　第三部分：

　　23　A A說的是：用X射線檢查可能對年輕女人不好。下面是第二段講的意思：但是，用x射線檢查年輕女人，就醫(yī)學上的好處而論，是有爭議的，部分原因是輻射有誘發(fā)癌癥的小小的危險。另外，年輕女人****組織緊密，給予的X射線的劑量要多一些。

　　24　B B說的是：調(diào)查用X射線檢查的結(jié)果。第三段的第一句話是這么說的：Valencia理工大學的研究人員分析了11個社區(qū)診所用X射線檢查16萬以上女人的結(jié)果。可以看出，這句話為真，B必須為真。

　　33　B文章第四段告訴我們：…algae will produce hydrogen in an airfree environment.沒有空氣的情況肯定就沒有氧氣了。該段最后一句又說，是氧阻止綠藻制造氫。

　　34　D選項A、B都不是正確答案，因為短文的第六段告訴我們，remove sulfate和work in an airfree environment都是可能的，但問題是兩者都有弊端，使氫的制造不那么容易。D所述內(nèi)容就是困難之一：綠藻細胞因為沒有了sulfate而減緩工作速度，因此產(chǎn)生了多少氫。

　　35　C根據(jù)短文最后一段的描述，綠藻可以在任何地方生長，它們是很容易使用的燃料能源，而且用途廣泛，所以，A、B、C都是正確的描述，不是答案。C是答案，因為“The organisms are cheap to get and to feed”中的feed是“養(yǎng)殖”的意思，不能解釋為“吃”。

　　36　C細節(jié)題。答案在第一段第一句：自從開始發(fā)明創(chuàng)造以來，人們一直在設計越來越多的工具來應付危險的、枯燥乏味的、繁重的或是令人討厭的工作。由此可知，C為正確答案。

　　37　C語意題。文章第一段說：人類發(fā)明了各種工具，利用各種機器為人類服務;第二段第一句說，“結(jié)果，當今世界出現(xiàn)了越來越多的智能化gizmos”。由此可以推斷，gizmos最有可能是機械工具一類的東西，因此，選項C應為正確答案。

　　38　D細節(jié)題。答案在第三段最后一句：Dave Lavery說，我們現(xiàn)在還沒法設計出能有足夠的常識去應付一個動態(tài)世界的機器人。D項：獨立地應付一個不斷變化的世界，符合此意。

　　39　B細節(jié)題。還是引用第三段第二句Dave Lavery的話：我們知道怎樣讓機器人去應付一個具體的錯誤。接下來第五段第二句說：科學家已制造出的機器人能以不到一毫米的精確度識別機器面板上的誤差?？梢夿為正確答案。

　　40　C作者觀點態(tài)度題。作者在最后一段第二句開始向我們傳達了這樣一個信息：機器人、人工智能，雖然能為人類做很多工作，但與人的大腦智能、感知能力相比，還相差甚遠。人類能在瞬間識別出猴子或可疑的面孔。所以，C：機器人就識別相關(guān)信息而言，比人腦差得多。

　　41　B細節(jié)題。由一段第二句可知：世界原油價格的上漲是因為OPEC決定減少供應。

　　42　D推斷題。第三段第三句說：在歐洲，油稅占了汽油零售價的五分之四。因此可推知，如果油稅上漲，汽油的零售價也會隨之上漲。

　　43　D細節(jié)題。第四段第一句說：經(jīng)濟發(fā)達國家對石油的依賴性比過去低，對油價的浮動也不怎么敏感。接著說：最近一期的經(jīng)濟瞭望雜志估計：和l998年的每桶13美元相比，如果油價持續(xù)一年在22美元左右的話，石油進口支出也只占了發(fā)達國家國內(nèi)生產(chǎn)總值(GDP)的0.25%——0.5%。由此可知，油價的上漲對發(fā)達國家的GDP影響甚微。D項正確。

　　44　A推斷題。第三段至第五段的內(nèi)容表明，這次油價的上漲對全球經(jīng)濟影響不大，不會像1973年、l979年、l980年那樣，引起全球恐慌。所以，A為正確答案。

　　45　A作者觀點態(tài)度題。綜觀全文，結(jié)合上兩題的分析，可以看出作者對這次油價上漲的影響力抱樂觀的態(tài)度。

　　第五部分：

　　46　C第一段主要介紹對未來的預測。作者問讀者，所列的各種高科技的發(fā)展的預測是不是會在2000年發(fā)生?“空白1”所在的句子說，實際上有人預測在1978年會發(fā)生。根據(jù)這個上下文，選項C所說的the article was written in l958，填入此處意思是連貫的。1958年寫的文章預測20年之后的高科技的發(fā)展。

　　47　D“空白2”后面以but引導的句子說的是would have space for farms and fields，此處所示的內(nèi)容應該是與space有關(guān)。選項D的內(nèi)容是Cities of the future would not be crowded，是與space有關(guān)的，應該是答案。

　　48　F第三段第一句的前半句說專業(yè)人士預測不準，because之后的“空白”應該是說明預測不準的原因。選項F的future study is still a new field是合情合理的原因。所以，選F是必然的。

　　49　A“空白”后面的分詞短語ruining thousands of investors，從上下文判斷，應該是結(jié)果狀語，“空白4”與之存在著因果關(guān)系。此外，investors提示，此處填入的內(nèi)容應該與經(jīng)濟有關(guān)。選項A的內(nèi)容是the stock market had its worst losses ever，完全符合上述的判斷。

　　50　B最后一段是總結(jié)段，指出預測的不準確性。結(jié)束前用調(diào)侃的語氣寫道，要預測2000年將發(fā)生的事情，有一件事是不會預測錯的：今年出生的嬰兒到 2000年會如何如何。選項B是will have reached the age of 43，應該是本題的答案。

　　文章大意：蜘蛛網(wǎng)對蜘蛛來說不僅僅是家，它們還是奇妙的引蟲入網(wǎng)的陷阱。有一種網(wǎng)絲有超強的彈力，叫做蜘蛛的避敵絲。當雌性的準備紡織蛛網(wǎng)的幅條和框架時，它就用腿從它腹部一個中空的噴嘴里勾出累飄飄的絲線。避敵絲不粘，因此蜘蛛可以沿著它來回活動紡織，從而來紡織網(wǎng)的標志性螺旋。

　　51　A flying bird飛入蜘蛛網(wǎng)時有股沖力，網(wǎng)線堅韌才能捕捉到它，所以選tough。本句中的without breaking 也指示選tough。

　　52　B英語中蜘蛛網(wǎng)絲是spider silk。見第三、第四段分別出現(xiàn)的silky thread和spider silk。

　　53　D本句說蜘蛛織網(wǎng)的機制和過程，所以選weave。而且，這種蜘蛛就叫Golden Orb Weaver。

　　54　C從上下文判斷，alon9之后接的是the dragline，其代詞應為it。

　　55　D本句說Golden Orb Weaver與某些種類的蜘蛛不同，它不用每天織新網(wǎng)，只要網(wǎng)不破，就能一直使用下去，有時一用2年，所以選reuses。

　　56　C本句將Golden Orb Weaver蜘蛛網(wǎng)的牢度和張度與防彈衣Kevlar材料對比，說明該蜘蛛網(wǎng)堅韌的程度。填入的詞應該是Kevlar的同位語，Kevlar是一種材料，所以選material。

　　57　B除了上下文的意思要求填length之外，本句中的用詞stretch和longer都指示要用 length。

　　58　A come后面可接形容詞。come close意為“接近”。come well，come open，come awake都能搭配，但意思與上下文不符。

　　59　C It is no wonder(that)是“不足為奇，十分自然”的意思。只有選wonder意思才連貫。

　　60　B從意義上判斷，a steady supply是正確的選擇。shipment(運送)、run(運轉(zhuǎn))或exchange(交換)的意思與上下文配不上。

　　61　D上下文的意思要求用“起作用”這個詞，work在本句的詞義是“起作用”。

　　62　C下一句是以next開始的。有next，前面很可能有first之類表次序的詞。

　　63　A常識告訴我們，把dragline silk proteins分泌在milk里，才容易分離出來，所以選meat、lungs或muscle都是不合常理的。

　　64　B在without之后要用any，一般不用some。英語不說without no…，而many不能修飾help。

　　65　A本題只能選as fast as。若選B、C或D，意思與上下文不符。
