Unfortunately, thin-film silicon solar cells are vulnerable as some bad-newsphysics in the form of the Staebler-Wronski effect.

10、ice for Earth’s Waters（A級）鯊魚有益于地球水系 It is hard to get people to think of sharks as anything but a deadly enemy. They are thought toattack people frequently. But these fishperform avaluable service for earths waters and for human beings. Yet business and sport fishing3are threatening theirexistence.

11、 Some sharks are at risk of disappearing fromEarth Warm weather may influence both fish and shark activity. Many fish swim near coastal areasbecause of their warm waters. Experts say sharks may follow the fish into the same areas,where people also swim. In fact, most sharks do not purposely charge

12、at or bite humans. They are thought to mistake a personfor a sea animal, such as a seal or sea lion. That is why people should not swim in the ocean when the sun goes down or comes up. Those are thetimes when sharks are looking for food. Experts also say that bright colors and shiny jewelry may caus

13、e sharks to attack. A shark has an extremely good sense of smell4. It can find small amounts of substances in water, such as blood, body liquids and chemicalsproduced by animals. These powerfulsenses help sharks find their food. Sharks eat fish, anyother sharks, and plants that live in the ocean.

14、Medical researchers want to learn more about the shark’s body defense, and immunesystems against disease. Researchers know that sharks13recoverquickly from injuries. They study the shark in hopes of finding a way to fight human disease. Sharks are important for the world’soceans. They eat injured a

15、nd diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become toogreat. This protects the plants and other forms of life that exist in the oceans. +第十五篇 “Liquefaction” Key to Much of Japanese Earthquake Damage（A級） The massive subduction zon

16、e1 earthquake in Japan caused a significant level of soil "liquefaction"2 that has surprised researchers with its widespread severity, a new analysis shows. "Weve seen localized3 examples of soil liquefaction as extreme as this before, but the distance and extent of damage in Japan were unusually s

17、evere," said Scott Ashford, a professor of geotechnical engineering4 at Oregon State University5. "Entire structures were tilted and sinking into the sediments," Ashford said. "The shifts in soil destroyed water, drain and gas pipelines6, crippling the utilities and infrastructure these communities

18、need to function. We saw some places that sank as much as four feet." Some degree of soil liquefaction7 is common in almost any major earthquake. Its a phenomenon in which soils soaked with water, particularly recent sediments or sand, can lose much of their strength and flow during an earthquake.

19、This can allow structures to shift or sink or collapse. But most earthquakes are much shorter than the recent event in Japan, Ashford said. The length of the Japanese earthquake, as much as five minutes, may force researchers to reconsider the extent of liquefaction damage possibly occurring in

20、 situations such as this8. "With such a long-lasting earthquake, we saw how structures that might have been okay after 30 seconds just continued to sink and tilt as the shaking continued for several more minutes," he said. "And it was clear that younger sediments, and especially areas built on rece

21、ntly filled ground, are much more vulnerable." The data provided by analyzing the Japanese earthquake, researchers said, should make it possible to improve the understanding of this soil phenomenon and better prepare for it in the future. Ashford said it was critical for the team to collect the inf

22、ormation quickly, before damage was removed in the recovery efforts9. "Theres no doubt that well learn things from what happened in Japan10 that11 will help us to reduce risks in other similar events," Ashford said. "Future construction in some places may make more use of techniques known to reduce

23、 liquefaction, such as better compaction to make soils dense, or use of reinforcing stone columns." Ashford pointed out that northern California have younger soils vulnerable to liquefaction ---on the coast, near river deposits or in areas with filled ground. The "young" sediments, in geologic term

24、s, may be those deposited within the past 10,000 years or more. In Oregon, for instance, that describes much of downtown Portland, the Portland International Airport and other cities. Anything near a river and old flood plains is a suspect12, and the Oregon Department of Transportation has already

25、concluded that 1,100 bridges in the state are at risk from an earthquake. Fewer than 15 percent of them have been reinforced to prevent collapse. Japan has suffered tremendous losses in the March 11 earthquake, but Japanese construction standards helped prevent many buildings from collapse ---even a

43、romoted C improved D postponed 14. A transformer B adaptor C transmitter D collector 15. A boosted B defined C wasted D lower 答案與題解： 1.D 文章介紹最近科學(xué)家已經(jīng)完善了太陽能光伏熱能系統(tǒng),現(xiàn)在新型的太陽能系統(tǒng)能將太陽能轉(zhuǎn)換為更多的電能和熱能。第一段說明以往晶體硅太陽能電池在收集熱能方面效率很低。四個選項中，只有選用until 才符合上下文的意

44、思?！啊璾ntil now they ( 太陽能光伏熱能系統(tǒng)）havent been very good at the heat-generating part compared to a stand-alone solar thermal collector.該句意為：與太陽熱能單機(jī)集熱器相比直到現(xiàn)在，傳統(tǒng)太陽能光伏熱能系統(tǒng)在轉(zhuǎn)換熱能方面效率一直不是很高。 2. A 本句說明了以往的太陽能光伏熱能系統(tǒng)在轉(zhuǎn)換熱能方面效率低的原因, “to cool crystalline silicon solar cells( 冷卻晶體硅太陽能電池) ” 能產(chǎn)生更多的電能，但不利于收集熱能。elect

45、ricity 是答案。 3. C 從上一段和本段的意思判斷，收集熱能效率低下不會是一個動力學(xué)(dynamics）問題，地質(zhì)( geology) 問題或生物學(xué)( biology ) 問題。它是一個經(jīng)濟(jì)上的問題。答案是economics. 4. B 本句說，good solar hot-water systems 在收獲能量方面比solar-electric system 要好得多。從經(jīng)濟(jì)學(xué)的角度上分析，成本就降低了。所以，選cost 是對的。其他選項reward ，bill和pay均不符合句意. 5. B 上一段說光伏電池系統(tǒng)有兩個問題. 即經(jīng)濟(jì)問題和空間問題。Joshua P

46、earce 采用另外一種硅制造PVT來解決上述問題。通過上述分析可以看出，他尋求的是一種解決問題的辦法( solution ) ，而不是一個決定( decision) 、一個建議( suggestion ) 或一種資格( qualification）。 6.C amorphous silicon ( 非晶硅) 即為thin-fi1m silicon ( 薄膜硅) 。選擇roughly/probably/wrongly ( known as thin-film silicon ) 表達(dá)的意思都不合邏輯。選commonly才合理。“amorphous silicon，commonly kno

47、wn as thin-film silicon”意為“非晶硅，通常被稱為薄膜硅。 7. D 新型的太陽能電池采用薄膜硅制造，電能的轉(zhuǎn)換量雖然不如晶體硅太陽能池，但薄膜硅太陽能電池用硅量小，比較環(huán)保。本題應(yīng)選用require ，理由是：require much less silicon 與上下文的意思很連貫，而retrieve much less silicon ( 提取少得多的硅) merge much less silicon ( 混合少得多的硅) 或exchange much less silicon ( 交換少得多的硅) 都講不通，意思離題太遠(yuǎn)。 8.A bad-news p

48、hysics 是解題的關(guān)鍵詞。既然是bad-news physics，所連用的形容詞應(yīng)該是負(fù)面意義的詞。四個選項中只有vulnerable ( 易受攻擊的) 符合這個條件， 所以是答案。 9.D 本段第一句說明vulnerable 的具體情況。既然是vulnerable ，efficiency 一定是drops，不會是rises。efficiency works(效率起作用)或efficiency counts（效率有重要意義)都離題太遠(yuǎn)。 10. C 薄膜硅太陽能電池效能低下，這是因。導(dǎo)致該產(chǎn)品市場占有份額很小，這是果。 選reasons 為答案很合理。 11.C 為了克服

49、SWE. 效應(yīng)Pearce 和他的團(tuán)隊悉心改進(jìn)光伏太陽熱能系統(tǒng)的結(jié)構(gòu)。作者要寫的應(yīng)該是a new type of PVT( 一種新型PVT) ，不會是a new shape/size/brand PVT( 一種新形狀的/新尺寸的/新品牌的PVT)。 12.B 從上下文判斷，答案應(yīng)該是point。將thin-film silicon 加熱到solar-thermal operating temperatures 就是加熱到near the boiling point of water ( 臨近水的沸點(diǎn)) 。其他選項area，place 和extent 均不切題. 13. 從上下文判斷

50、，采用加熱t(yī)hin-film silicon 的方法，就能消除SWE 效應(yīng)。四個選項中只有overcame 表達(dá)了這層意思。 14.D 答案是collector，因?yàn)閟olar thermal energy collector( 太陽能集熱器) 與上下文的意思接得上，意為“當(dāng)把薄膜硅直接應(yīng)用于太陽能集熱器時” 其他選項均與上下文不符。 15. A 文章最后一段介紹研究人員克服SWE 效應(yīng)，提高了將太陽能轉(zhuǎn)換為電能的效率。 所以，將最后一句的“by 10 percent”理解為“提高”而不是“降低”10%才合乎邏輯。答案是boosted。 +第十四篇Sharks Perform

63、D mountains 15. A weak B little C few D great 答案與題解： 　　1．A本題應(yīng)選擇attack，因?yàn)榈谝痪湔f到：人們認(rèn)為鯊魚是a deadly enemy，也就是說鯊魚會對人類造成傷害。第二句是對deadly enemy的具體說明。其他的三個選項meet，love，visit都不合適，love與上下文意思相反，meet和visit與上下文意思不符。 　　2．C空格2所在的句子由but連接，所以該句子表達(dá)的意思一定與第二句相反。第二句對 　　鯊魚的評價是負(fù)面的，填入空格2的詞應(yīng)該是正面的。四個選項中只有va

64、luable符合這一條件，所以是答案。 　　3．B第三句說到鯊魚有益于“waters and human beings”，第五句又說到鯊魚瀕臨滅絕的危險。根據(jù)上下文的意思，threatening(威脅)到它們的應(yīng)該是existence(生存)。其他的三個選項source，friends，fish都不合適，與上下文意思沒有聯(lián)系。 　　4．D如果鯊魚消失，從什么地方消失呢?當(dāng)然從earth(地球)上消失。從space(宇宙空間)、sky(天空)中消失，或從land(陸地)上消失，都有悖常理。 　　5．C四個選項的意思都是“因?yàn)椤?，但是從用法上分析，because、since和by reaso

65、n that之后要接句子，because of之后接名詞或名詞短語。their warm waters是名詞短語，所以要選用because of。 　　6．D“…people also swim”明顯是定語從句，其先行詞是表示地點(diǎn)的名詞area，所以要選關(guān)系副詞where．。 　　7．B從上下文判斷，本句的意思是：鯊魚將人錯認(rèn)為是海洋動物。而“將……錯認(rèn)為是”的英語表達(dá)是mistake…for，所以本題的答案是選項B。 　　8．A本段的意思是：鯊魚并非故意襲擊人類。人們認(rèn)為，由于鯊魚將人錯認(rèn)為是海獅等海洋動物，在饑餓時才襲擊人類。日出和日落時，正是鯊魚饑腸轆轆的時候，人們不應(yīng)該出海游泳?？崭?填入的詞應(yīng)該與時間有關(guān)，所以times是答案，而與地點(diǎn)有關(guān)的選項(places seas和oceans)與上下文意思脫節(jié)。 　　9．C本段第一、二句是說，鯊魚的嗅覺特別靈敏，能嗅到海水中存在的極為微量的氣味。作者舉了三個物質(zhì)：血、體液和化學(xué)品?？崭?要填入表示物質(zhì)的名詞。四個選項中惟一表達(dá)物質(zhì)的詞是chemicals(化學(xué)品)。所以chemicals是答案，而其它三個選項與學(xué)科有關(guān)，脫離了上下文的意思，不是本題的答案。 　　10．B在第一、二句意思的基礎(chǔ)上，作者進(jìn)一步說明，靈敏的嗅覺有助于鯊魚找到食物。所以本題的答案是選項D的senses，因?yàn)閒eelings
