参考答案:

16A本题的意思是:Genera技术公司研制出一种方法,这种方法可以确定

水是否是清洁的。题句的意思与原文第二句相符,故选A。

17C本题的意思是:在成立Genera公司之前,Parton曾在一家英国水厂工

作。原文中并没有提到公司成立前Parton是否在一家英国水厂工作,故选C。

18B本题可译为:这种新产品在美国获得了商业上的巨大成功。原文的意

思是预计该产品在美国会卖得很好,还没在美国上市呢。本题句的意思与原文不

19A本题可译为:这种测试产品每件售价42500美元。同原文意思相符,

故选Ao

20B本题可译为:年底前,Genera公司又订购了25件这种测试产品。Genera

公司本身是卖这种测试产品的,不是它又订购了25件这种产品。与原文意思相

反,故选Bo

21C本题的意思是:英国政府正帮助Parton销售这种产品。原文根本没有

提到这一信息,故选C。

22A本题可译为:最近,Genera的雇员增加了。见原文最后一段,原来公

7.Morethan10chipplantsbeingbuiltinthatcountryareanexampleof

A.RightB.WrongC.Notmentioned

参考答案:

IB分析:利用题干中的特征词US$14million作为答案线索,这样发现答案

相关句:Thecenter,whichwillstartoutwithaboutUS$14million„willhelpthe

countrydevelopitschipindustrywithoutalwaysdependingonimported

technology.(该句句意不足以说明问题句是否正确)

Morethan10chipplantsarebeingbuilt,eachcostingmillionsofU.S.dollars.

Themajorityofthatmoneygoestooverseasequipmentvendors(卖主)and

technologyowners-mainlyfromJapanandSingapore.

Shouldthenewcenterplayamajorroleinimprovingthesituationinthe

industry,thecountryadmitstheUS$14millioninvestmentisstillrathersmall,(the

situationintheindustry的指代内容是解题关键,而前句中提到的是chipindustry

的发展,因此判断"thesituationintheindustry"就是指"芯片工业的发展情况",

所以根据该句的句意(1400万美圆的投资仍然是很小数目的投资)判断问题句的

说法不正确。)

2.C.分析:以题干中的核心结构militarypurposes和toppriorities作为答案线

索(同时注意文章中出现的这些线索结构的近义/反义结构),于是发现相关句:

Currently,chipplantsinthiscountryareinapassivesituationbecausemanyforeign

governmentsdon/tallowthemtoimportthemostadvancedtechnologies,fearing

theywillbeusedformilitarypurposes.

发现答案相关句中没有谈到"优先发展用于军事目的的芯片",因此判断问题

句的说法为"没提到"。

3.C.分析:利用题干中的核心结构licensingfees(执照费)作为答案线索(因为

该词是特定的表达,所以可以在文章中只查找该词),查找答案相关句:Moreover,

thehighlicensingfees(与“arenotveryhigh"不矛盾)theyhavetopaytotechnology

providerarealsoanimportantreasonfortheirdecisionofself-reliance.发现相关句

的内容中只涉及到了问题句中的部分内容(有关执照费用的高低问题),而问题句

中提到的"cannotaffordtopay(没能力支付)”在文章中没有对应的内容,因此判断

问题句的说法为“没提到〃。

4.A.分析:该题所涉及到的相关句在第2题中已经出现了:Currently,chip

plantsinthiscountryareinapassivesituationbecausemanyforeigngovernments

don'tallowthemtoimportthemostadvancedtechnologies,fearingtheywillbe

usedformilitarypurposes.(许多国外政府不允许他们进口最先进的技术,因为担

心这些技术将被用于军事目的)根据该句句意判断问题句的说法正确。

5.C.分析:利用题干中的核心词flagshipchipmakers作为答案线索,这样在

文章中找到答案相关句:Theadvent(出现,到来)ofthecenterwillpossiblyfreethe

countryfromthesituationthatitisalwaysbuyingalmost-outdatedtechnologies

fromothercountries,saidthecountry'sflagshipchipmaker.文章中涉及至Uflagship

chipmaker的句子并没有说flagshipchipmaker是由美国投资者所拥有,可见文章

中的答案相关句中根本没有反映出问题句中的信息,因此判断该问题句的为没提

到。

6.A.分析:利用题干中的核心词Mainstreamchip作为答案线索,这样在文

章中找至I」相关句:Asmainstreamchipproductiontechnologyshiftsfromone

generationtothenexteverythreetofiveyears,该句含义是“主流芯片生产技术每

3年到5年就会进行更新换代”,根据该句句意判断问题句的说法“正确〃。

7.B.分析:利用题干中的特殊结构-数量词(10chipplants)作为答案线索,这

样发现答案相关句:Morethan10chipplantsarebeingbuilt,eachcostingmillionsof

U.S.dollars.Themajorityofthatmoneygoestooverseasequipmentvendorsand

technologyowners-mainlyfromJapanandSingapore.从相关句中得出的结论恰恰

是“依靠他人",而不是"依靠自己〃,因此判断问题句的说法错误。

A.Right
