6、ses.1A.carry BputCturn Dthink答案A解析考查動(dòng)詞。根據(jù)“multiple tasks”可知，此處用carry較為合適，語境表示那些真正同時(shí)可以把多項(xiàng)工作做好的人僅占人口的百分之二。2A.interestingly BstrangelyCactually Dnormally答案C解析考查副詞。此處用actually說明一種事實(shí)。更令人驚奇的是這些所謂的一次可以做多種工作的人的大腦和其他人的大腦構(gòu)造不同。3A.result BseparateCconclude Ddiffer答案D解析考查動(dòng)詞。由上文可知一次可以做多種工作的人的大腦和其他人的大腦構(gòu)造不同。所以用diff

7、er from.表示“不同于”。4A.humans BanimalsCplants Dmonkeys答案A解析考查名詞。由下文中的“nonhuman primates”可知此處應(yīng)用humans。5A.conscious BunsureCaware Dskeptical答案B解析考查形容詞?？茖W(xué)家們拿不準(zhǔn)為何一些大腦是不同的。根據(jù)語境可知用unsure“無把握”。conscious意識(shí)到；aware知道；skeptical懷疑的，均不符合語境。6A.single BsimpleCcomplex Dimportant答案A解析考查形容詞。從上文中的“Yet scores of studies su

8、ggest that real multitaskers.”可以看出整理主張一次只完成一項(xiàng)任務(wù)。single用于強(qiáng)調(diào)。7A.suggested BindicatedClocated Dinferred答案C解析考查動(dòng)詞。語境表示科學(xué)家們?cè)诖竽X中確定瓶頸的準(zhǔn)確位置。故只有l(wèi)ocate“確定的準(zhǔn)確位置”符合語境。8A.easy BhardChandy Dcomfortable答案B解析考查形容詞。由上文中的“bottleneck in the brain”可知一心二用是困難的。9A.reason BproblemCresult Dconclusion答案B解析考查名詞。本段意在說明瓶頸問題的起因，

9、因此用problem，這一問題似乎是由神經(jīng)信息的阻塞引起的。10A.different BinterestingCsimultaneous Dridiculous答案C解析考查形容詞。由首句信息可知文章探討的是人們能否一心二用的問題，即是否可以同時(shí)做兩件事，simultaneous同時(shí)發(fā)生的，同步的。11A.mental BneuralCproper Dpossible答案B解析考查形容詞。由上文中的“The problem appears to be caused by a logjam of nerve messages.”可知，此處涉及的是神經(jīng)系統(tǒng)的反應(yīng)。故用neural“神經(jīng)系統(tǒng)的”。

10、12A.energy BeffortCinformation Dattention答案D解析考查常識(shí)。根據(jù)常識(shí)可知“e­mails，phone calls，text messages and online social media”是會(huì)使我們分散注意力的。故應(yīng)選D項(xiàng)。13A.acquire BachieveCmake Dreach答案D解析考查動(dòng)詞。由上文中的“e­mails，phone calls，text messages.against a background of television，radio or music”可知，我們的大腦是在超負(fù)荷工作。只有reach適

11、合，此處意為“達(dá)到信息超負(fù)荷”。achieve通常指達(dá)到目標(biāo)。14A.volunteers BpatientsCstudents Dworkmen答案A解析考查名詞。由下文中的“.attempting to multitask on a computer.”可知，這些被檢測(cè)的對(duì)象不是特定的職業(yè)，應(yīng)是志愿者。15A.similar BsuperiorCdifferent Dsenior答案C解析考查形容詞。由上文中的“.multitask on a computer.”可知，需要多種感官參與，故用different。.語法填空The Stand Your Ground law is not ye
