解析：1.D〔提示:細節(jié)理解題。根據(jù)第一段最后一句和第二段最后一句可知塑料袋生產(chǎn)商雇用StevenStein是為了證明他們的產(chǎn)品片不像大多數(shù)人想象的那樣對地球有害.是對塑料袋被禁用的解釋和爭論,故選D?！?/p>

2.A〔提示:詞義猜測題。上文介紹在許多美國大城市塑料袋被禁用.看到這種現(xiàn)狀,塑料袋生產(chǎn)商雇用StevenStein等科學家是為了證明他們的產(chǎn)品并不像大多數(shù)人想象的那樣對地球有害。headwinds"逆風",此處指塑料袋被禁用的現(xiàn)狀,即Bansonplasticbags,故選A?！?/p>

3.D〔提示:細節(jié)理解題。根據(jù)第四段However,longerlastingreusablebagsoftenrequiremoreenergytomake.可知塑料袋生產(chǎn)商認為生產(chǎn)耐用且能重復使用的袋子需要更多的能源,故選D?！?/p>

4.A〔提示:主旨大意題。文草講述了使用塑料袋造成的環(huán)境問題。紙袋容易回收,但生產(chǎn)和運輸需要更多的能源,希望消費者使用耐用可重復使用的袋子,Plastic,PaperorNeither既能概括全文,又能吸引讀者.最適合作為標題.故選A?！矯答案：DCDA解析：1.D〔提示:細節(jié)理解題u根據(jù)文章的整體理解可知，在科學家霍金的MyBriefHistory而不是ABriefHistoryofTime這本書里介紹了霍金是如何鍛煉成天才的，故答案為D項.,〕

2.C〔提示:推理判斷題。根據(jù)文章最后段標題“Alwayslookforasilverlining(evenifyouareseriouslyill)”，并結(jié)合最后一段的整體理解可推知.在困境中看到陽光的一面有利于人們發(fā)展成為天才，故答案為C項?！?/p>

3.D〔提不:推理判斷題。根據(jù)第二段“InhisrecentlypublishedautobiographyMyBriefHistory,Hawkingoffersfourlifelessonsonhowtobeeagenius.”可推知，霍金的這本介紹如何成為天才的書是一本自傳體書，因此他卞要是通過自己的經(jīng)歷來闡述自己的觀點的，故答案為D項?！?/p>

4.A〔提示：推理判斷題。根據(jù)最后一段第一句“Hawking’sdiseasehasslowlyrobbedhimoftheabilitytowalk…”可知選A?！矰答案：1.C;2.B;3.D;4.C

解析：1.考查細節(jié)理解。根據(jù)第二段中的"Outsideanytraditionalpubworthyofitstitle,you'llfindahangingsignboardwithauniqueillustration(插圖)thatrepresentsthenameofthebusiness"可知,英國酒吧標牌的獨特之處在于上面都有代表店名的獨一無二的插圖。故選C.

2.考查細節(jié)理解。根據(jù)第三段中的"Sincemostofthepopulationwereunabletoread,pubsignswereusedtoinformwouldbecustomersthattheycouldfindadrinkinside"可知,最初英國酒吧的標牌主要是用來通知潛在的顧客進店喝一杯的。故選B。

3.考查推理判斷。根據(jù)文章最后一段中的"Todaythetraditionremainsunchangedlargelyoutofrespectforthepast,butmanypubsignsdohavesomefunctionality"可知,現(xiàn)代英國酒吧的標牌實用性更強。所以現(xiàn)代酒吧標牌的使用目的與以前不同。故選D。

4.考查主旨大意。通讀全文可知,本文主要講述了英國酒吧標牌的發(fā)展,故選C。答案：B;F;C;G;D解析：本文是一篇說明文,主要介紹了為了取得成功,應(yīng)該停止做的四件事1.B此處是本段小標題。根據(jù)其他小標題的句式及該段落中的首句和最后一句可以推知B項符合語境。2.F根據(jù)上文中的"Differentpeoplemayexplain‘success,indifferentways"和下文中的"Don’tworryaboutwhatotherpeoplethinkbutgoafterwhatmakesyouhappy”可知應(yīng)選F項。3.

C根據(jù)小標題"Donotbelieveanythingwithoutquestioningit"和C項中的"notjustacceptanynewinformationto

betrue”與該段中的"questionnewinform?ation"相呼應(yīng)可知,此處應(yīng)選C項。4.G本段主要講的是要擔心可能會發(fā)生在你身上的預見的事情",根據(jù)空前講的"如果你想要成功,就不要去想任何或許會發(fā)生在你身上的事情”可知,這里應(yīng)進一步說明,故選G項。5.

D根據(jù)小標題"Donotcareaboutwhatotherpeoplethinkofyou"及D項中的"pleaseallthepeople"與該段中的"thequantityofpeopletoplease"相呼應(yīng)可知,應(yīng)選D項。答案：1.A;2.B;3.A;4.B;5.D;6.A;7.B;8.C;9.B;10.D;11.B;12.A;13.B;14.A;15.B;16.B;17.C;18.D;19.A;20.B

解析：1.A〔提示:makefulluseof充分利用。句意為“他允分利用他所巧察到的事實?！??！?/p>

2.B〔提示:bebasedon/upon以....為基礎(chǔ):基于....。句意為“他從不接受沒杏依據(jù)于觀察事實基礎(chǔ)上的理論?！??！?/p>

3.A〔提示:根據(jù)句子意思.此處是指“不能接受某種權(quán)威來說真理的合法性”,應(yīng)用reason?！?/p>

4.B〔提示:checkv.證明無誤,核對無誤。句意為“他總是認真核實想法并通過做實驗來證明它們?！??！?/p>

5.D〔提示:根據(jù)下文的內(nèi)容可以判斷出,在此處是要表達modernscience(現(xiàn)代科學)的意思?！?/p>

6.A〔提示:dateback是間定同組,意為“回溯至”?！?/p>

7.B〔提示:根據(jù)文意判斷,此處用time(時代,年代)?！?/p>

8.C〔提示:根據(jù)文意判斷,此處用between與and連用,表示“在...和...之間”〕

9.B〔提示:theMiddleAges意為“中世紀,中古時代”?！?/p>

10.D〔提示:表示通過某種方式用by。根據(jù)文意判斷我們必須通過觀察和實驗來研究在我們周圍的事物進而得知科學?！?/p>

11.B〔提示:makeadiscovery為固定搭配?！?/p>

12.A〔提示:who在此引導一個非限制性定語從句,修飾先行詞greatmen,且在從句中充當主語成分,指人?！?/p>

13.B〔提示:bydegrees為固定詞組,意為“逐漸地”,相當于gradually?！?/p>

14.A〔提示:truth意為“事實,真理,原理
