第十篇Chicken Soup for the Soul: Comfort Food Fights Loneline Mashed potatoes, macaroni and cheese, may be bad for your arteries, ____1____ according to a study inPsychological Science, they’re good for your heart and____2____.“comfort food1 ” and how it makes people feel.“For me____3____, food has always played a big role in my family”, says Jordan Troisi, a graduate student2 at the University of Buffalo3,and lead author4 on the study.The study came out of the research program of his co-author Shira Gabriel.It has____4____ non-human things that may affect human emotions.Some people reduce loneline by bonding with their____5____ TV show, building virtual relationships with a pop song singer or looking at pictures of loved ones.Troisi and Gabriel wondered if comfort food could have the same effect____6____ making people think of their nearest and dearest5.In one experiment, in order to make____7____ feel lonely, the researchers had them write for six minutes about a fight with someone close to them.Others were given an emotionally neutral writing aignment.Then, some people in each____8____ wrote about the experience of eating a comfort food and others wrote about eating a new food.____9____ the researchers had participants____10____ questions about their levels of loneline6.Writing about a fight with a close person made people feel lonely.But people who were generally____11____ in their relationships would feel le lonely by writing about a comfort food.“We have found that comfort foods are consistently aociated with those close to us,” says Troisi.u Thinking about or consuming these foods later then serves as a reminder of those close others.” In ____12____ eays on comfort food, many people wrote about the____13____ of eating food with family and friends.In another experiment,____14____ chicken soup in the lab made people think more about relationships, but only if7 they considered chicken soup to be a comfort food.This was a question they had been asked long before the experiment, along with many other questions, so they wouldn’t remember it.Throughout everyone’s daily lives8 they experience stre, often aociated with our ____15____ with others, “Troisi says.‘‘Comfort food can be an easy remedy for loneline.词汇:
mashed / mæʃt / adj.被捣成糊浆的 macaroni / ,mækə'rəʊnɪ / n.通心粉 cheese / tʃiːz / n.奶酪 artery / 'ɑːtərɪ / n.动脉
aignment / ə'saɪnmənt / n.指定作业
reminder / rɪmaɪndə / n.起提醒作用的东西 remedy / remɪdɪ / n.治疗方法,药物 virtual / vɜːtjʊəl / adj.虚拟的
注释:
1.comfort food:爽心食品 2.graduate student:研究生
3.The University of Buffalo:布法罗大学,建校于1846年,位于水牛城(Buffalo City),属于纽约州立大学,因此称为纽约州立大学水牛城分校。4.lead author:首席作者
5.their nearest and dearest:他们最接近和最亲爱的人 6.levels of loneline:孤独程度 7.only if:只有(在……情况下)
8.Throughout everyone’s daily lives:在每一个人的日常生活中。through有“贯穿”的意思。练习:
1.A but B if C though D while 2.A personality B movement C emotions D will 3.A privately B usefully C awfully D personally 4.A looked for B looked at C looked after D looked up 5.A favorite B trustful C boring D annoying 6.A with B on C by D at 7.A profeors B participants C aistants D scientists 8.A group B cla C section D part 9.A Previously B Formally C Initially D Finally 10.A remember B explain C rewrite D complete 11.A sad B secure C shy D angry 12.A your B our C his D their 13.A accident B harm C experience D model 14.A eating B exchanging C buying D keeping 15.A expreions B estimation C cooperation D connections 答案与题解:
1.A 本句前半句说土豆泥、通心粉等对血管有害(bad),后半句说这些食物对心脏有利(good)。很明显,前半句与后半句意思相反,所以要选转折连接词but加以连接。
2.C 根据常识判断,吃土豆泥不会对personality(性格)movement(移动)或will(意志力)产生有利影响。随后的文章,多处提到吃爽心食品(comfort food)有助于排解孤独感。所以,选emotions是正确的。
3.D 本题的答案是personally。For me personally(就我个人而言)与下文的意思很连贯。privately(私下地)、usefully(有用地)或awftilly(可怕地)与下文的意思搭不上,所以不会是答案。
4.B 本题的答案是looked at。“looked at non-human things”相当于“studied(研究)non-human things”,与上下文的意思很匹配。looked for(寻找)、looked after(照顾)和looked up(查找)与下文的意思搭配不上。
5.A 本句的意思是:人们为了排解孤独感,常常把自己和电视剧、流行歌曲歌手等等联系起来。选项中有四个形容词,应该选哪一个形容词去修饰TV shows呢?应该选褒义的形容词:favorite(喜爱的)或trustful(可信任的)。但对电视剧来说谈不上信任的问题。favorite最合理,是本题答案。
6.C 上一句说到,人们为了排解孤独感,常常把自己和喜爱的电视剧、流行歌曲歌手等联系起来。于是Troisi和Gabriel想,通过吃爽心食品让他们想起亲近的人,是不是也能产生同样的排解孤独感的效果呢?四个介词中只有by的词义是“通过”。其余三个介词在词义上都不合适。
7.B 选profeors(教授)、aistants(助手)或scientists(科学家)不合常理,科学家选实验对象时不会选他们。participants(参与者)是本题的答案。
8.A 本题应该选group,备每一组的参与者。用cla(班级)、section(部门)或part(部分)在意义上显然都不合适。
9.D 本段叙述试验的几个步骤。第一步要一部分受试者描写与亲人的争斗,其他受试者写情感上中性的话题。第二步(文中用then加以连接)将上述两组受试者中的每一组再一分为二,一些人描写吃爽心食品的经历,另一些人描写吃新食品的经历。接下来应该是第三步了。从四个选项中寻找,只有Finally最合适,原来第三步就是最后一步了。
10.D 实验的最后一步是受试者被要求书面回答10个问题。complete是答案。要求他们remember(记住)、delete(删除)或rewrite(重写)questions都不合乎逻辑。
11.B 与亲近的人争吵会引发孤独感,但是,一般来说,人们的关系若是通常处于什么状态,通过写出他们吃爽心食品的经历会降低他们的孤独感呢?一定不会是sad,shy或angry,答案应该是secure(稳定的)。
12.D 修饰eays的所有格代词在人称与数上要与they一致,所以their是答案。
13.C “eating food with family and friends”是一种experience(经历),不会是一个accident(事故)、harm(危害)或model(样式)。很明显,experience是本题的答案。
14.A 文章中几次提到吃爽心食品有助于缓解孤独感,所以本题选eating是很自然的。其他三个选项,exchanging(交换)、buying(买)或keeping(保留)若填入句子中,与后面的宾语chicken soup in the lab连用,意思上说不通。
15.D 本题的答案是connections。其他三个选项在意思上都不合适。
第九篇Wonder Webs
Spider webs are more than homes, and they are ingenious traps.And the world’s best web spinner may be the Golden Orb Weaver spider.The female Orb Weaver spins a web of fibers thin enough to be invisible to insect prey, yet____1____ enough to snare a flying bird without breaking.The secret of the web’s strength? A type of super-resilient____2____ called dragline.When the female spider is ready to____3____ the web’s spokes and frame, she uses her legs to draw the airy thread out through a hollow nozzle in her belly.Dragline is not sticky, so the spider can race back and forth along____4____ to spin the web’s trademark spiral.Unlike some spiders that weave a new web every day, a Golden Orb Weaver____5____ her handiwork until it falls apart, sometimes not for two years1.The silky thread is five times stronger than steel by weight and absorbs the force of an impact three times better than Kevlar, a high-strength human-made____6____used in bullet-proof vests.And thanks to its high tensile strength, or the ability to resist breaking under the pulling force called tension, a single strand can stretch up to 40 percent longer than its original____7____and snap back as well as new.No human-made fiber even comes____8____.It is no____9____ manufacturers are clamoring for spider silk.In the consumer pipeline: high-performance fabrics for athletes and stockings that never run2.Think parachute cords and suspension bridge cables.A steady____10____ of spider silk would be worth billions of dollars — but how to produce it? Harvesting silk on spider farms does not____11____ because the territorial arthropods have a tendency to devour their neighbors.Now, scientists at the biotechnology company Nexia are spinning artificial silk modeled after Golden Orb dragline.The____12____ step: extract silk-making genes from the spiders.Next, implant trie genes into goat egg cells.The nanny goats that grow from the eggs secrete dragline silk proteins in their____13____.“The young goats pa on the silk-making gene without____14____ help from us,” says Nexia president Jeffrey Turner.Nexia is still perfecting the spinning proce,but they hope artificial spider silk will soon be snagging customers____15____ the real thing snags bugs.词汇:

1.sometimes not for two years:相当于sometimes it does not fall apart for two years。2.run:(编织物)抽丝 练习:
1.A tough B soft C large D smooth 2.A cloth B silk C nylon D wool 3.A repair B pull C move D weave 4.A him B her C it D those 5.A refixes B reproduces C remakes D reuses 6.A metal B ma C material D model 7.A bredth B length C height D strength 8.A close B well C open D awake 9.A hurry B worry C wonder D use 10.A shipment B supply C run D exchange 11.A run B go C deal D work 12.A previous B foremost C first D front 13.A milk B meat C lungs D muscle 14.A no B any C some D many 15.A as fast as B as long as C as fully as D as little as 答案与题解:
1.A flying bird飞入蜘蛛网时有股冲力,网线坚韧才能捕捉到它,所以选tough。本句中的without breaking也指示选tough。
2.B 英语中蜘蛛网丝是spider silk。见第三段、第四段分别出现的silky thread和spider silk。
3.D 本句说蜘蛛织网的机制和过程,所以选weave。而且,这种蜘蛛就叫Golden Orb Weaver。
4.C 从上下文判断,along之后接的是the dragline,其代词应为it。
5.D 本句说Golden Orb Weaver与某些种类的蜘蛛不同,它不用每天织新网,只要网不破,就能一直使用下去,有时一用两年,所以选reuses。
6.C 本句将Golden Orb Weaver蜘蛛网的牢度和张度与防弹衣材料Kevlar对比,说明该蜘蛛网坚韧的程度。填入的词应该是Kevlar的同位语,Kevlar是一种材料,所以选material。
7.B 除了上下文的意思要求填length之外,本句中的用词stretch和longer都指示要用length。
8.A come后面可接形容词。come close意为“接近”。come well,come open,come awake都能搭配,但意思与上下文不符。
9.C It is no wonder(that)是“不足为奇,十分自然”的意思。只有选wonder意思才连贯。
10.B 从意义上判断,a steady supply是正确的选择。shipment(运送)、run(运转)或exchange(交换)的意思与上下文配不上。
11.D 上下文的意思要求用“起作用”这个词,英语work在本句的词义是“起作用”。
12.C 下一句是以next开始的。有next,前面很可能有first之类表次序的词。
13.A 常识告诉我们,把dragline silk proteins分泌在milk里,才容易分离出来,所以选meat,lungs或muscle都是不合常理的。
14.B 在without之后要用any,—般不用some。英语不说without no...,many不能修饰help。
15.A 本题只能选as fast as。若选B、C或D,意思与上下文不符。
第六篇Car Thieves Could Be Stopped Remotely
Speeding off1 in a stolen car, the thief thinks he has got a great catch2.But he is in a nasty3 surprise.The car is fitted with a remote immobilizer, and a radio signal from a control center miles away will ensure that once the thief switches the engine____1____ , he will not be able to start it again.For now, such devices____2____ only available for fleets of trucks4 and specialist vehicles used on construction sites.But remote immobilization technology could soon start to trickle down to ordinary cars5,and____3____ be available to ordinary cars in the UK____4____ two months.The idea goes like this.A control box fitted to the car incorporates6____5____ miniature cellphone, a microproceor and memory, and a GPS7 satellite positioning receiver.____6____ the car is stolen, a coded cellphone signal will tell the unit to block the vehicle’s engine management system and prevent the engine____7____ restarted.There are even plans for immobilizers____8____ shut down vehicles on the move8, though there are fears over the safety implications of such a system.In the UK, an array of9 technical fixes10 is already making____9____ harder for car thieves.“The pattern of vehicles crime has changed,” says Martyn Randall of Thatcham, a security research organization based in Berkshire11 that is funded in part____10____ the motor insurance industry.He says it would only take him a few minutes to____11____ a novice how to steal a car, using a bare minimum of tools12.But only if the car is more than 10 years old.Modern cars are a far tougher proposition13, as their engine management computer will not____12____ them to start unle they receive a unique ID code beamed out14 by the iginition key.In the UK, technologies like this____13____ achieve a 31 per cent drop in vehicle-related crime15 since 1997.But determined criminals are still managing to find other ways to steal cars.Often by getting hold of the owner’s keys in a burglary.In 2000, 12 per cent of vehicles stolen in the UK were
taken by using the owner’s keys, which doubles the previous year’s figure.Remote-controlled immobilization system would____14____ a major new obstacle in the criminal’s way by making such thefts pointle.A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the____15____ expects.词汇:
immobilizer n.使车辆不能调动的装置 cellphone n.移动电话,手机 ignition n.点火 trickle v.慢慢移动
immobilization n.使车辆不能调动 burglary n.夜窃行为;盗窃 注释:
1.speed off:超速驾驶 2.catch:捕获物,猎获物

D specialist 答案与题解:
1.A 该段主要是说,如果车被盗,只要发出无线电信号,remote immobilizer就能使被盗车一旦停下就无法再启动。因此,应选择A。如选择B,switches the engine on(发动引擎)句子意思便不符合文章内容。C和D与switch不搭配。
2.D devices是复数形式,描述的也是目前的事情,所以应使用be的现在时复数形式are。
3.D 该句说,这种遥控技术很快就会开始一点一点地用于普通汽车。然后作者推断,在两个月后这种技术就能用于英国的汽车。A是错误选项,因为该句前面用了could表示委婉的推断,在此不会用can;B和C与意思不符,should也是表示推断。
4.C 从搭配上来看,可以选择B和C,但是从意思上来看,必须选择C。for two months:已经有两个月了;in two months:两个月后。不能选择A,因为不符合英语表达习惯。又如:They will graduate in one year.他们一年后毕业。
5.C 这里应该使用不定冠词,而且miniature cellphone后面的并列定语都使用不定冠词。不能选择an,因它后面的名词由辅音开头。
6.B 从语法结构来看,这里应选择引导状语从句的连词,其他选项都会造成结构错误。而且,If正符合句子的意思。
7.B prevent sth.(from)doing是固定用法,restart这里要用被动语态being restarted,所以应选择B。
8.C 从句子的结构来看,这里需要一个关系代词引导定语从句。关系代词的先行词immobilizers是物不是人,所以只能用that,不能用who。
9.A 在四个选项中,B、C和D显然不符合文章的意思。这里作者要表达的意思是:使……日子难过,所以应选择A。
10.C be funded是被动语态,空格后面是名词短语,从句子的意思来判断,这个名词短语是动作fund的执行者,是谓语动词动作逻辑上的主语,所以必须使用by来引导这个名词短语。
11.D 这个句子结构是:to take sb.time to do sth.。从意思上判断,句子的意思应该是:他说只要花几分钟就能教会一个新手如何偷盗汽车。所以,D是答案。use,inform和ask都不能与how to结构搭配。
12.B them后跟着to,所以首先排除A和C(let sb.do sth.)。句子的意思不允许选D。...will not allow them to start...:……不允许它们启动。
13.A 句子后面的时间状语由since引导,所以句子应该使用现在完成时。
14.D 从obstacle in the criminal’s way这个名词短语看出,应选择D,构成put obstacle in sb.’s way(给某人设置障碍)这种固定用法。
15.C 前面有go on the market,预期的人应该是customer。当然,specialist,doctor或lawyer也可以预期,但总不及customer那么自然。
译文:远程制止偷车贼
超速驾驶在偷来的汽车里,偷车贼以为自己大获全胜。但是他马上就会又惊又恼。车上已经被装了远程制动装置,一个几英里以外的控制中心发来的无线信号将确保盗贼一旦启动引擎,他就不能再次发动汽车了。目前,这种装置只用于卡车队或者用于建筑工地的特殊车辆上。但是远程制动技术很快就会逐步应用到普通汽车上。并且应该在两个月之内用在英国的普通汽车上。
计划是这样的。把一个集合有微型无绳电话,微量处理器,存储器以及全球定位系统的卫星接收器的控制盒子安装在汽车上。如果汽车被盗,一个被编码的无绳电话信号就会告诉这个装置停止车辆引擎控制系统来阻止弓I擎再次被启动。
甚至还有一些人主张计划将制动装置装在运行着的车辆上,可是这样一来人们就会担心这个系统的安全性。在英国,二系列的技术装置已经让盗车贼步履维艰了。玛丁兰多来自位于贝克郡的一个由汽车保险工业投资成立的名为撒策姆的安全研究机构,他说,“车辆盗窃的手法已经有所改变。”他还声称只要是10年以上的汽车,他就能用几样简单的工具在几分钟之内教会一个新手怎样偷车。
现代车却远没有这么简单,因为它们的引擎管理计算机装置只有接收到一个独一无二的由点火钥匙发送过来的身份密码才可以启动汽车。自1997年以来,在英国,技术人员已经利用此项技术帮助减少了31%的涉及车辆犯罪案。但是不死心的盗贼们却还在一直想方设法偷车。例如很多时候,他们在夜里盗走主人的汽车钥匙进而偷车。在2000年,英国12%的车辆被盗案是由于主人的钥匙被盗,这个数字比前一年增长了1倍。
远程控制的制动系统给盗贼设置了一个全新的障碍。包括撒策姆、公安部门、保险公司以及安全技术公司在内的一个群体已经为体系开发出了一些标准,它们将比顾客所预期的更早地被推广到市场上。
第七篇An Intelligent Car
Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain.Many human drivers have all ____1____ and can control a fast-moving car.But how does an intelligent car control itself?
There is a virtual driver1 in the smart car.This virtual driver1 has “eyes”, “brains”, “hands” and “feet”, too.The minicameras ____2____ each side of the car are his “eyes”, which observe the road conditions ahead of it.They watch the ____3____ to the car’s left and right.There is also a highly ____4____ driving system in the car.It is the built-in computer, which is the virtual driver’s “brain”.His “brain” calculates the speeds of ____5____ moving cars near it and analyzes
their positions.Basing on this information2, it chooses the right ____6____ for the intelligent car, and gives ____7____ to the “hands” and “feet” to act accordingly.In this way, the virtual driver controls his car.What is the virsual driver’s best advantage3? He reacts ____8____.The minicameras are ____9____ images continuously to the “brain.” It ____10____ the proceing of the images within 100 milliseconds.However.the world’s best driver ____11____ needs one second to react.____12____, when he takes action, he needs one more second.The virtual driver is really wonderful.He can reduce the accident ____13____ considerably on expreways.In this case, can we let him have the wheel4 at any time and in any place? Experts ____14____ that we cannot do that5 just yet6.His ability to recognize things is still ____15____.He can now only drive an intelligent car on expreways.词汇:
coordination n.协调,协同 virtual adj.虚拟的 minicamera n.微型相机 accordingly adv.相应地 millisecond n.毫秒 expreway n.高速公路 注释:
1.virtual driver:虚拟驾驶员
2.Basing on this information:基于这些信息。Basing on this information是现在分词短语,用作状语。
3.best advantage:最大的优点
4.have the wheel:掌握方向盘,也就是“驾驶汽车”的意思。
5.that:that替代上一句的“let him have the wheel at any time and in any place”。
6.just yet:迄今还。yet意为“迄今还”,常用于否定句中。just修饰yet,起强调的作用。练习:

D Therefore 13.A count
B amount
C digit
D rate 14.A warn
B suggest
C invite
D check 15.A unknown
B few
C untested
D limited 答案与题解:
1.A 第一句提到的是eyes,ears,brain等,指示代词应该用复数形式的these,不能选this
或that。选them也不对,因为all them不符合习惯用法,正确的说法是all of them。
2.D side前面要求用介词on。
3.B 选项B中traffic的意思是“流动的车辆”,是本题的答案。police(警察)、trucks(重型卡车)和buses(公共汽车)表达的意思都是路况的一部分,显然与现实不符。
4.C 从上下文判断,本句的意思应该是高度自动化的驾驶系统,所以答案是automatic。其余三个选项(mechanical机械的、movable可移动的、electronic电子的)表达的意思与上下文配不上。
5.B 从下文判断,本句说的是“其他流动的车辆”,所以要选用other。another意为“另一个”,each other和one another都是“互相”的意思,与上下文表达的意思相去甚远。
6.D 上下文的意思要求选path(路径)。line(线路)、lane(车道)和track(车辙),意思虽与path接近,但是讲不通。
7.C 本句前半句说的是电脑选定了路径,接下来自然是“……给‘手’发出指令(instructions),‘手’就做出相应的动作”。所以,C是答案。space,locations,time的词义与上下文的意思衔接不上。
8.A 通段讲的是虚拟驾驶员的反应速度,所以只能选quickly。
9.C bring是“带来”,take是“带走,接受(命令)”,send是“发送(命令)”,carry是“携带”。从上下文判断,应该是“...sending images continuously to the ‘brain’”。
10.B 前一句说的是微型摄像机将图像送入电脑,接下来的意思应该是电脑处理图像,完成处理图像所需的时间为100毫秒。根据上下文表达的意思,应该选B。
11.A 本句的起始词是However,表示本句的意思与上一句的意思形成对比。上一句说电脑完成图像处理只需100毫秒,第二句说,最好的驾驶员处理的时间要长得多,应该是at least rieeds one second。所以,A是答案。
12.C 上一句说,最好的驾驶员至少需要1秒钟的时间才能完成图像处理。本句进一步说,他做出动作还需1秒钟的时间,这两句的意思是层层深入,所以要选C。
13.D 根据上下文判断,此处要表达的应该是“事故率”。rate是“比率”,所以答案是D。count(计数)、amount(数量)、digit(0~9中任何一个阿拉伯数字)都不对。
14.A can we let him have the wheel at any time and in any place?”涉及交通安全、人命关天的问题,都谈不上什么“邀请(invite)”、“建议(suggest)”、“检查(check)”。所以,答案只能是warn(警告)。
15.D 本句是给出目前不能let smart car have the wheel at any time and in any place的原因。原因是它的能力limited(有限)。对smart car的能力一无所知(unknown)或是没有测试过 11
(untested),显然与前文的意思不符。few只能与可数名词搭配,ability在本句中是不可数名词,所以few也不是答案。
译文:智能汽车
开车需要目光锐利,耳朵灵敏,反应敏捷和手脑间的协作。许多人类司机这些条件都具备,并可控制一辆急速行驶的汽车。但一辆智能车如何进行自控? 智能车中有一位虚拟驾驶员。这位司机同样有“眼”有“脑”有“手”有“脚”。车两侧的微型摄像头就是他的眼,负责观察车前方的路况。他们注意着车两侧的交通情况。车中也有高度自动化的驾驶系统。这就是内置的电脑,也就是虚拟司机的大脑。这个大脑计算出车近旁正在运动车辆的速度,并分析它们的位置。基于这些信息,它为智能车选择最佳路径,并给出指示以让手脚做出相应运动。通过这样的方式,虚拟司机就对车辆实行了控制。
虚拟司机的最大优点是什么?他的反应速度很快。微型摄像头不断向大脑发送图像数据。他完成图像处理的时间为100毫秒。然而,世界上最优秀的人类司机也至少需要1 秒钟的反应时间。当他作出行动时,又多需一秒。
虚拟司机的确很棒。在高速公路上,他可大大减少事故发生率。鉴于此,我们是否可以让他在任何时间任何地点都驾驶汽车呢?专家们警告说我们现在还不能这样做。智能 车辨别事物的能力还很有限。目前,这种车只能在高速公路上行驶。
