19、 in almost any major earthquake. it's 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 recent

44、tor15. 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(yáng)能光伏熱能系統(tǒng),現(xiàn)在新型的太陽(yáng)能系統(tǒng)能將太陽(yáng)能轉(zhuǎn)換為更多的電能和熱能。第一段說(shuō)明以往晶體硅太陽(yáng)能電池在收集熱能方面效率很低。四個(gè)選項(xiàng)中，只有選用until 才符合上下文的意思。“until now they ( 太陽(yáng)能光伏熱能系統(tǒng)）haven't been very good at the heat-generating part compared to a stand-alon

45、e solar thermal collector.該句意為：與太陽(yáng)熱能單機(jī)集熱器相比直到現(xiàn)在，傳統(tǒng)太陽(yáng)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(shuō)明了以往的太陽(yáng)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(yáng)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(huì)是一個(gè)動(dòng)力學(xué)(dynamics）問(wèn)題，地質(zhì)( geology) 問(wèn)題或生物學(xué)( biology ) 問(wèn)題。它是一個(gè)經(jīng)

46、濟(jì)上的問(wèn)題。答案是economics.4. b 本句說(shuō)，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(duì)的。其他選項(xiàng)reward ，bill和pay均不符合句意. 5. b 上一段說(shuō)光伏電池系統(tǒng)有兩個(gè)問(wèn)題. 即經(jīng)濟(jì)問(wèn)題和空間問(wèn)題。joshua pearce 采用另外一種硅制造pvt來(lái)解決上述問(wèn)題。通過(guò)上述分析可以看出，他尋求的是一種解決問(wèn)題的辦法( solution ) ，而不是一個(gè)決定( decision) 、一個(gè)建議( suggestion )

47、 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(yáng)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(yáng)能池，但薄膜硅太陽(yáng)能電池用硅量小，比較

48、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(gè)選項(xiàng)中只有vulnerable ( 易受攻擊的) 符合這個(gè)條件， 所以是答案。

49、0;9.d 本段第一句說(shuō)明vulnerable 的具體情況。既然是vulnerable ，efficiency 一定是drops，不會(huì)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(yáng)能電池效能低下，這是因。導(dǎo)致該產(chǎn)品市場(chǎng)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(duì)悉心改進(jìn)光伏太陽(yáng)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(huì)是a new shape/size

50、/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(xiàng)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(gè)選項(xiàng)中只有overcame 表達(dá)了這層意思。 14.d 答案是collector，因

51、為solar thermal energy collector( 太陽(yáng)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(yáng)能集熱器時(shí)” 其他選項(xiàng)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(yáng)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 earth's watersit is hard to get people to think of sharks as anythin
