1、完形填空模擬檢測(七)　說明文 (共2篇，限時35分鐘) A New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study, __1__ in the latest edition of Ecol

The authors write that, having survived warm periods in the

9、明文。主要講述了一項最新的研究，研究表明氣候變暖不會使亞馬孫古代樹種滅絕。 1．A.advertised　　　　　　 B．described C．published D．presented 解析：選C　此處表示《生物與進化》的最新版發(fā)表的一項研究。故選C。 2．A.frightening B．surprising C．exciting D．interesting 解析：選B　根據(jù)下文“more than 8 million years”可知，亞馬孫一些樹種的年齡是令人吃驚的(surprising)。 3．A.still B．nevertheless C．however

10、 D．therefore 解析：選D　這些古代樹種有著超過800萬年的樹齡，因此(therefore)表明了它們可以幸存于和先前所有時期一樣溫暖的全球氣候變暖的時期，預測為2100年。前后意義上為因果關系。 4．A.assess B．confirm C．forecast D．promise 解析：選C　根據(jù)下文“the year 2100”可知，將來時間只能是預測(forecast)。 5．A.particularly B．probably C．merely D．possibly 解析：選B　既然亞馬孫的樹種曾在高溫氣候中生存下來，所以將來也有可能(probably)在氣

11、溫升高的氣候中存活。 6．A.Since B．Although C．When D．If 解析：選B　雖然隨著溫度的升高，嚴重的干旱及森林火災將會影響亞馬孫流域，但這些樹木將會忍受更高溫度的直接影響。故選B。 7．A.rise B．change C．drop D．end 解析：選A　由本句末的“higher temperatures”可知此處應是溫度升高。故選A。 8．A.consider B．decide C．guarantee D．recommend 解析：選D　空后面是作者的建議，故選D。 9．A.based B．built C．focused D．m

12、ade 解析：選C　此處表示保護措施應當仍然集中于防止為了農(nóng)業(yè)和礦業(yè)的發(fā)展而采伐森林。故選C。 10．A.in relation to B．in response to C．in reply to D．in reference to 解析：選B　這項研究與最近其他研究不同的是他們預測樹種的滅絕是對相對小幅度的全球平均氣溫升高的反應。in response to“響應，回答，對……做出反應”，故選B。in relation to“關于，涉及”；in reply to“答復……”；in reference to“關于”。 11．A.findings B．thoughts C．

13、inventions D．writings 解析：選A　根據(jù)上一段中的“The study”，再結(jié)合第一段第一句中的“previous findings”可知答案選A。 12．A.threats B．disadvantages C．embarrassments D．instructions 解析：選A　此處是指干旱和過度采伐森林對于亞馬孫的未來來說仍然是主要的威脅(threats)。故選A。 13．A.accept B．tolerate C．permit D．require 解析：選B　雖然樹種好像能忍耐比現(xiàn)在更高的溫度，但亞馬孫森林正在向農(nóng)業(yè)和礦業(yè)轉(zhuǎn)變。根據(jù)上文第7空

14、后的“stand the direct impact of higher temperatures”也可知，此處應用stand的同義詞tolerate。故選B。 14．A.farming B．planting C．catering D．mining 解析：選D　由第二段最后一句中的“deforestation(采伐森林) for agriculture and mining”可知選D。 15．A.power B．influence C．desire D．violence 解析：選B　此處指當這里沒有人類影響的時候。故選B。 16．A.difficult B．clear

15、 C．easy D．important 解析：選A　現(xiàn)在氣候變化極快，使之與過去緩慢地變化比較起來很難。故選A。 17．A.belief B．direction C．understanding D．suggestion 解析：選C　更清楚地理解了亞馬孫森林所面對的危險，我們推斷出(conclude)人類直接的影響，比如為了農(nóng)、礦業(yè)而采伐森林，仍是保護政策的重點。 18．A.doubt B．conclude C．calculate D．prefer 解析：選B　參見上題解析。conclude“推斷，做結(jié)論”。 19．A.thought B．guidance C．pr

16、otection D．a(chǎn)ction 解析：選D　為了把干旱和火災的風險降到最低并保護(secure)亞馬孫樹種的未來，我們也需要更多積極的行動來減少溫室氣體的排放。action“行動”。 20．A.secure B．a(chǎn)dvance C．sacrifice D．evaluate 解析：選A　參見上題解析。secure“保護，使安全”。 B For many people today, reading is no longer relaxation.To keep up their work they must read letters, reports, trade publi

23、material in a short period of time. 語篇解讀：本文是一篇說明文。閱讀本來是一項愉悅身心的活動，但是忙碌的工作使人們閱讀時帶有很強的目的性。本文就如何開展有效的快速閱讀進行了簡單的說明。 1．A.applying　　　　　　　 B．doing C．offering D．getting 解析：選D　此處說的是“謀得一份差事”。apply需加for，意思是“申請”；do“做”； offer“提供”。此三項均不符合題意，只有get(獲得)適合。 2．A.quickly B．easily C．roughly D．decidedly 解析：選A　

24、句意為“快速閱讀與理解的能力，是決定成敗的關鍵所在”。只有quickly與原意吻合。easily“容易地”；roughly“粗略地”； decidedly“果斷地”。 3．A.good B．curious C．poor D．urgent 解析：選C　英語中，閱讀速度快的人稱為good reader，反之，就是poor reader。根據(jù)上下文的內(nèi)容，多數(shù)人都屬于poor reader，因此選poor。 4．A.training B．habits C．situations D．custom 解析：選B　此處的意思是“大多數(shù)人在早期養(yǎng)成看書慢的習慣”。habit“習慣”；tra

25、ining“訓練，培訓”；situation“形勢”；custom“風俗習慣”。 5．A.lies B．combines C．touches D．involves 解析：選A　此處說的是“主要的困難在于語言的自身要素，即單詞”。lie與in構(gòu)成搭配，意為“在于”。combine“聯(lián)合”；touch“接觸”；involve“包括”。 6．A.some B．a(chǎn) lot C．little D．dull 解析：選C　這里的意思是“如果單個地看這些詞，它們并沒有什么意義”。little“很少”是否定詞，合乎邏輯。some“一些，若干”；a lot“許多”；dull“單調(diào)的”。

26、7．A.Fortunately B．In fact C．Logically D．Unfortunately 解析：選D　此句語境為“作者對未受過閱讀訓練的人的不良閱讀習慣感到遺憾”。unfortunately“不幸地”，合乎語境。fortunately“幸運地”；in fact“事實上”；logically“合乎邏輯地”。 8．A.reuse B．reread C．rewrite D．recite 解析：選B　此處語境為“未受過閱讀訓練的讀者在閱讀時經(jīng)常重讀(反復讀)”。故選reread“重讀”。reuse“再使用”；rewrite“改寫”；recite“背誦”。 9．

27、A.what B．which C．that D．if 解析：選A　此處所填的詞既是look back over的賓語，又是you have just read的賓語，只有what能充當這種雙重成分。 10．A.scales B．cuts C．slows D．measures 解析：選C　scale down“按比例減少”；cut down“削減”；這兩項不符合題意。 measure不能與down搭配。slow down“放慢”，符合語境。 11．A.some one B．one C．he D．reader 解析：選B　此處用one，表泛指。 12．A.accel

28、erator B．a(chǎn)ctor C．a(chǎn)mplifier D．observer 解析：選A　語境為“訓練快速閱讀所使用的工具必然與提高閱讀速度有關”，因此選accelerator“快讀器”。第14空前“The accelerator”亦是提示。actor“演員”；amplifier“放大器”；observer“觀察者”。 13．A.then B．a(chǎn)s C．beyond D．than 解析：選D　前面的faster決定了選than，構(gòu)成比較級。 14．A.enabling B．leading C．making D．indicating 解析：選C　此句意為“快速閱讀器迫使

29、你加快閱讀速度，使你再也不能逐字閱讀，回顧前文內(nèi)容或者默讀”。make“使，使得”，符合語境。enable相當于make possible；lead“引導”；indicate“指出，表明”。 15．A.meaning B．comprehension C．gist D．regression 解析：選B　這里的意思是“速讀最初會影響理解”，所以選comprehension“理解”。第16空后“your comprehension”亦是提示。meaning“意義，意思”，指詞匯或短語表示的意義；gist“大意，要旨”；regression“回歸”。 16．A.but B．nor C．

30、or D．for 解析：選A　與前半句中的not only相呼應，構(gòu)成句式not only ... but (also)．..“不僅……而且……”，故選but。 17．A.our B．your C．their D．such 解析：選C　本句中的主語是第三人稱復數(shù)Many people，故此處應用物主代詞their。 18．A.Look at B．Take C．Make D．Consider 解析：選B　take與后面的for instance構(gòu)成短語，意為“以……為例”，其他三項不能構(gòu)成搭配。 19．A.for B．in C．a(chǎn)fter D．before 解析：選D　這里指受訓練之前與受訓練之后的比較，因此選before。 20．A.refer to B．go over C．set about D．get through 解析：選D　此處語境為“在短時間內(nèi)，讀完更多的材料”。refer to“參考”；go over“復習”；set about“著手做”。只有get through“讀完”最恰當。 8
