评【语篇导读】本文是一篇应用文。文章主要介绍了无人机XPro是无人机市场上的一颗闪亮之星以及它如此受欢迎的原因。1.A细节理解题。根据第四段第三句“Youcaneasilycontrolandflythisdrone,evenifyou’ven

everflownadroneinyourlife.”可知,你可以很容易地控制和驾驶这架无人机,即使你从未驾驶过无人机。由此可知,不难控制是无人机XPro不同于其他无人机的地方。故选A项。B项“质量很好”在文中没有被提到;根据第二段第一句和第三句

首先把无人机应用程序安装到你的智能手机,之后再把电池放在无人机里并启动应用程序可知,C项、D项不正确。2.A推理判断题。根据第四段第五句“Ourfriend’ssoncameovertotheoffice,andhefiguredouthowtoflyt

hedroneinjustminutes.”可知,我们朋友的儿子来到办公室,他在几分钟内就弄明白如何驾驶无人机。由此可推断,该广告通过例子证明驾驶无人机容易操作。故选A项。3.C细节理解题。根据第六段第一句“Now,DroneXProsellsfor$150eachonlineandtw

oatadiscountof80%.”可知,现在DroneXPro在线售价是一架150美元,两架的折扣为80%。因此两架无人机是240美元。故选C项。【语篇导读】本文是一篇记叙文。SrikanthBolla出生在印度一个村庄,他生下来就是盲人,虽然那里的

人都认为残疾人没用,但是他的父母没有放弃他,反而努力培养他,最终他于2012年成立了以残疾人为主的BollantIndustries。4.B推理判断题。由第三段的最后两句“Unfortunately,thestu

dents...theentiredayalone.”和第四段第一句“Concernedthiswouldholdback...inHyderabad.”可知,在普通学校,老师和学生不喜欢Srikanth,父母担心这会影响Srikanth的成长,决定把他送到特殊学校。由

此可推知,在特殊学校,SrikanthBolla可以得到公平的对待。A、C、D三个选项相关信息文中并未提及。故选B项。5.B推理判断题。由第五段第二句“Forjustfouryears,itbecameapowe

rhousewithover450employees,70%ofwhomarephysicallychallenged.”可推知,SrikanthBolla是关心残疾人的。根据第一段中的“whowasborninasmal

lvillage”可知他出生在一个小村庄,但文中并未提到那个村庄是否贫穷,故排除A项;文中未提他父母对他是否严厉,故排除C项;文中未提及他年轻时受村民喜爱,因此D项可排除。故选B项。6.A推理判断题。根据第四段第二句“Sureenough,theyoungboysoo

nrosetothetopofhisclass,winningawardsinspeechanddebatecompetitions.”可知,SrikanthBolla是很聪明的(intelligent)。根据第四段最后一句“Notw

antingtogiveup,Srikanthtooklegalactionandbecamethefirstblindstudentinthecountryallowedtostudysciences.”可知,Srikanth

Bolla不被允许上科学课。他不想放弃,于是运用法律手段成了他们国家第一个上科学课的盲人学生,所以SrikanthBolla是意志坚定的(determined)。B项“积极和正直的”、C项“耐心和谨慎的”和D项“和善但顽

固的”都不符合文章对SrikanthBolla的描述。故选A项。7.D标题归纳题。文章一开始讲述SrikanthBolla出生地的人认为残疾就是无用的,文章中间段落讲述他父母对他的培养以及他自己的努力,最终没有让父母失望,还成立了自己的公司。所以本文主要讲“残疾并不意味着无能”,而不是A项的“机会

到处都有”和B项的“没有挑战就没有成功”,C项“大梦想起作用”脱离了SrikanthBolla的特殊性。故选D项。【语篇导读】本文是一篇说明文。文章讲述的是如何保护我们设备上的隐私。为防止恶意软件进入你的设备,请不要点击可疑的链接和电子邮件附件。在电子邮件、社交媒体和网上银行账户上使

用强密码。8.D词义猜测题。由第二段首句“Therearemanytypesofspywarethatcandiveintoourdevicesandsecretlyspyonthem,recordingeverythingtheydo.”可知

,有许多类型的间谍软件可以潜入我们的设备并秘密监视他们,记录他们所做的一切。由此可知,画线词them指代的是前面提到的devices,因此D项正确。9.B推理判断题。由第二段中的“bycompanieslikeNSOGroupwhocreate

dthePegasusspywareto‘provideauthorizedgovernmentswithtechnologythathelpsstruggleagainstterrorandcrime’”可知,这些公司“提供有助于打击恐怖主义和非法的科技给所授权的政

府”,由此推断,NSOGroup是研发间谍软件的公司,故选B项。10.C推理判断题。由第三段中的“Iftheyneedtogetanyinformation,theygetitbysendingatargetedmalwareto

yourdevice...topasswordsfromsocialnetworks,browserhistory,bankaccountsandmuchmore.”可推断,这种保护技术很难阻止恶意软件获取隐私,故选C项。11.

A主旨大意题。第一段提出人们如何保护个人信息,第二段讲述盗取个人信息的间谍软件;第三段作者认为我们高估了这种保护科技;第四段提到一根胶带显然不是保护你隐私的最有效工具;最后一段就保护隐私给出了建议。因此

可推断,本文讲述的是保护设备上的隐私,故选A项。【语篇导读】本文是一篇议论文。文章主要讨论了电动汽车和燃油汽车哪个更环保。12.B细节理解题。由第二段中的“TheteamfoundthatwhenEVsarechargedw

ithcoal-poweredelectricity,they’reactuallyworsefortheenvironmentthangas-poweredcars.”可知,当电动汽车消耗的是以煤为燃料的电能时,对环境造成的污染比燃油汽车更严重。13.A细节理解题。由第三段

中的“InChina,thenationalgridisimprovingwithmoreinvestmentsinrenewableenergy.”可知,中国电网正在加大对可再生能源的投资。14.C推理判断题。由第四段中的“Sheppardmodelledafutu

reinwhichallcarswereelectric...Forexample,SheppardcalculatedthatifallvehiclesintheU.S.wereelectric”可知,Sheppa

rd建立了一种推测电动汽车未来的模型:如果所有人都用电动汽车,将会产生什么样的结果。15.C推理判断题。由第五段中的“Aren’telectricvehiclestooexpensiveformostpeople?”可知,最后提出的问题是“电动汽车对大多数人来说是不是太贵了?”所以

接下来作者应是继续谈论“如何让电动汽车更实惠”。【语篇导读】本文是一篇说明文。文章主要介绍了如何在科学上取得成功。16.E根据空后的内容可知,作者认为只有和比自己聪明的人在一起才能学到东西,所以本段建议避免和愚蠢的人在一起。故选E项。17.C根据设空处前一句话可知,作者认为在科学或

生活的游戏中,最高的目标不仅仅是获胜,而是做成一些非常困难的事情。换句话说,最高目标是去超出自己能力范围的领域并名列前茅。C选项是对前一句话的进一步解释。18.G根据设空处前文可知,作者认为如果想取得巨大成功,科学家必须准备好陷入很深的困境中。

如果你要在科学上有一个巨大的飞跃,你很可能没有资格获得成功。此外,甚至也要准备好怀疑你心中的科学英雄,也就是要勇于质疑权威。故G选项符合语境。19.F根据设空处前一句话中的“dowellinsomethingIdislike”可知,在科学研究中,对于自己不喜欢的事情作者做不

好,但对于自己喜欢的事情作者也不一定能做好。故选F项。20.B根据前一段的内容可知,作者建议要和其他科学家交流,从而发现自己忽略的关键事实。甚至要和你的竞争对手交流,即使你觉得他们令人反感。因此本段建议如果你无法忍

受与你真正相匹敌的人一起工作,你就不要进行科学研究了。故选B项。【语篇导读】本文是一篇记叙文。RomayDavis在102岁时依然能自己开车去工作,她的一生一直在奋斗中。本文详细叙述了RomayDavis的个人经历及其所取得的成就。她毕生的奉献精神和强烈的职业道德激励着人们前行

。21.B根据上文“butshehasn’tletthatstopherfromworking”可知,102岁的RomayDavis仍然每天自己开车去杂货店工作,因此选B项,意为“仍然”。skillfully“熟练地”;yet“但是”。22.A根据上文

“butshehasn’tletthatstopherfromworking”以及下文“gobacktoworkandwasbythegrocerystoreinWinn-Dixiein2001atthea

geof82”可知,102岁的RomayDavis仍然每天自己开车去杂货店工作。故选A项。shopping“购物”;pleasure“快乐”;fun“乐趣”。均不符合题意。23.D根据“Davisisbeinghonoredforher...”以及“sheisapioneerherself

”可知,Davis因她的贡献而受到表彰。故选D项。contribution“贡献”。这句话的意思是:现在,在黑人历史月,Davis因她的贡献而受到表彰,一项拨款以她的名字命名。24.B这里的意思是,通过RomayDavis赠款计划,慈善机构将在争取种族平等和社会正义的斗争中获得支持。critici

sm“批评”;support“支持”;benefit“益处”;information“信息”,故选B项。25.A根据racialequality可知,慈善机构将在争取种族平等和社会正义的斗争中获得支持。justice“公平

”;skill“技能”;development“发展”,故选A项。26.C根据“assheisapioneerherself”可知,Davis名副其实。fond“喜欢的”;aware“有意识的”;worthy“值得的”;sure

“确定的”,故选C项。27.D根据“overseasduringWorldWarⅡ”可知,她在第一支驻扎于海外的全黑人女兵部队服役。require“要求”;root“植根于”;organize“组织”;s

tation“使驻扎”,故选D项。28.B根据“asadesignerinmodelinNewYorkfor30years”可知,她开始了自己的时尚生涯。style“风格”;career“职业”;study“学习”;adventure“冒险”。句意:战后,她开始了自己的时尚生涯,在纽约当了30年

的模特设计师。故选B项。29.D根据“includingamaster’sdegree,BlackBeltinTaekwondo(跆拳道)andmore”可知,在她的一生中,她还取得了其他里程碑式的成就。miss“错过”;achieve“完成,获得

”。句意:在她的一生中,她还取得了其他里程碑式的成就,包括硕士学位、跆拳道黑带等。故选D项。30.C根据下文“gobacktowork”可知,她在1982年第一次退休。fight“打仗”;pursue“追求”;ret

ire“退休”;fail“失败”。故选C项。31.D根据上文“Afterherhusbanddiedin2001”可知,2001年丈夫去世后,她决定重返工作岗位。refuse“拒绝”;fear“害怕”;mention“提及”;decide“决定”。故选D项。32.A根据上文“

gobacktowork”可知,她于2001年在82岁时受雇于Winn-Dixiein的一家杂货店。hire“雇佣”;pay“支付”;offer“提供”。故选A项。33.A根据下文celebrate可知,RomayDavis庆祝了她的100岁生日。ce

lebrate“庆祝”;pass“通过”;interview“面试”;employ“雇用”。故选A项。34.C根据下文strongworkethic(职业道德)以及上文contributions可知,我们都被她毕生的奉献精神和强烈的职业道德所感动。sympathy
