16、 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 severe, said scott ashford, a professor of geotechnical engineering4 at oregon state university5

17、. 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 need to function. we saw some places that sank as much as four feet.some degree of soil liquefactio

18、n7 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. this can allow structures to shift or sink or collapse. but most earthquakes are much shorter than the

19、 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 situations such as this8.with such a long-lasting earthquake, we saw how structures that might have been o

40、3. a overcame b promoted c improved d postponed14. a transformer b adaptor c transmitter d collector15. 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 才符合上下文的意思?！皍ntil now they ( 太陽能光伏熱能系統(tǒng)）havent been very g

41、ood at the heat-generating part compared to a stand-alone solar thermal collector.該句意為：與太陽熱能單機集熱器相比直到現(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。electricity 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)(dynamic

42、s）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 pearce 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 ) ，

43、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?！癮morphous silicon，commonly known 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

44、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 physics 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

45、) 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/si

46、ze/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) 。其他選項area，place 和extent 均不切題.13. 從上下文判斷，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，因為solar thermal e

47、nergy 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 a service for earths watersit is hard to get people to think of sharks as anything but a deadly enemy1. they
