19.Parents who smoke often open a window or turn on a fan to clear the air for their children,but experts now have identified a related threat to children's health that isn't as easy to get rid of:third-hand smoke.

"Everyone knows that second-hand smoke is bad,(43)A they don't know about this,"said Dr.Jonathan P.Winickoff,the lead author of the study and an assistant professor of Pediatrics at Harvard Medical School.

The study reported on (48)B towards smoking in 1,500households across the United States.It found that the vast majority of both smokers and nonsmokers were (49)D that second-hand smoke is harmful to children.Some 95percent of nonsmokers and 84percent of smokers (50)B with the statement that"inhaling smoke from a parent's cigarette can(51)A he health of infants and children".
But(52)C fewer of those surveyed were conscious of the(53)B of third-hand smoke.Since the term is so new,the researchers asked people if they (54)A the statement that"breathing air in a room(55)B  where people smoked yesterday can harm the health of infants and children".

分析 本文通过一项研究说明了人们陌生而又熟悉的三手烟对儿童的影响.解此完形填空的时候要注意把作者的思路逻辑和生活常识紧密结合,并注重联系上下文的语境逻辑.

解答 36---45  CBAAD    ABABD      46---55  CABDB    ACBAB
36.C 考查动词过去分词的含义辨析及在语言逻辑方面的准确应用.联系上下文的语境及日常生活中的常识,我们容易推理出这一句的语境是:所谓"三手烟"是用来指房间内的"二手烟"清除许久之后,仍残留在坐垫、地毯甚或吸烟者头发和衣物上看不见的气体和颗粒的有毒混合物.我们不难看出此处应该填上表示被用来之意的动词过去分词,也即是C项,而其余ABD项依次分别所表达的意思是:讲述,讨论,提及,这些词语所表示的意思都和这儿的语言逻辑不相吻合,故我们选择C项为最佳答案.
37.B考查名词.由上一题的分析和日常生活常识:香烟的残留往往存在于人的头发、衣服等等上面,我们不难看出此处应该填上表示衣服之意的名词,而ACD项依次分别所表达的意思是:鞋子,身体,嘴,只有B项有这样的意思,故B项为准确答案.
38.A 考查动词.由上一题的分析,联系上下文的语境,我们容易推理出这一句的语意是:残留物包含重金属、致癌物,甚至辐射物质,它们很容易沾在婴幼儿的手上并被吃到嘴里,尤其是当小孩子在地板上爬或玩耍时.不难看出此处应该填上表示包含包括之意的动词,而BCD项依次分别所表达的意思是:覆盖,发现,改进,这些意思在这儿都不符合此处的上下文之间语言逻辑,只有A项(includes:包括)有这样的意思,故A项为准确答案.
39.A 考查副词.由上一题的分析我们不难看出此处应该填上表示尤其之意的副词BCD项依次分别所表达的意思是:专门地,立即,规律地,这些意思在这儿都不符合此处的上下文之间语言逻辑,只有A项有这样的意思,并且用在这儿语句通顺合理,故A项为准确答案.
40.D考查动词.经过分析,语意是:在一项针对这些化学物质对婴幼儿危害的新的研究中,波士顿大众婴幼儿专科医院的医生们创造了"三手烟"这个词来形容它们.不难看出此处应该填上表示形容之意的动词,这四个词中只有D项有这样的意思.而其余ABD项依次分别所表达的意思是:命名,称作,解释,其中,AB两项容易让人上当,但是根据意思和语言逻辑,这是对这种化学物质类进行描述,如果命名的话,其后还得有个名称的词来补充说明,故D项为准确答案.
41.A 考查动词.由上一题的分析我们很容易看出此处应该填上表示针对(也就是以….为中心)之意的动词,A项就是这样的意思.BCD三项依次分别所表达的意思是:倾向于(和动词不定式搭配),尽力(也和动词不定式搭配),工作,这些词语所表示的意思都和这儿的语言逻辑不相契合,语意也通顺,故我们选择A项为最佳答案.
42.B联系上下文的语境,经过分析,语意是:研究结果发表于最近一期的《小儿科》医学期刊上.这四个词中只有B项有最近之意.其余ACD项依次分别所表达的意思是:迟到的,最后的,以前的,很明显放在这儿都不能使句意通顺,故B项为准确答案.
43.A 考查连词.联系上下文的语境,及日常生活中的常识,经过分析,语意是:每个人都知道二手烟有害,但他们却不知道三手烟的存在,不难看出此处应该填上表示但是之意的连词,这四个词中只有A项(but:但是)有这样的意思,而BD量项依次分别所表达的意思是:和,或者,放在这儿都不能使句意通顺.C项的具有很大的迷惑性,但是它作然而之意讲的时候是个副词,故我们选择A项为最佳答案.
44.B 考查介词的含义的准确记忆与理解.由日常生活中的常识,再联系上下文的语境,经过分析,语意是:只要孩子们在屋外,他们就可以吸烟.由语境我们不难看出此处应该填上表示在…的外面之意的介词,也即是B项,而其余ACD项依次分别所表达的意思是:和…一起,在…的里面,在….的旁边,这些意思在这儿都不符合此处的上下文之间语言逻辑,故B项为准确答案.
45.D 考查动词.由语境:或者在车上时,把孩子放在后座上,打开车窗,也可以吸烟.联系全文的语境,我们知道此处应该填上表示吸烟之意的动词,ABC项依次分别所表达的意思是:咳嗽,谈话,饮料,这些词语所表示的意思都和这儿的语言逻辑不相契合,故我们选择D项为最佳答案.
46.C 考查名词.联系上下文的语境,经过分析这一句的语意:他们认为这样就没有问题了,因为毕竟小孩子没吸到二手烟,我们不难看出此处应该填上表示孩子之意的名词,而ABD项依次分别所表达的意思是:轿车,座位,窗户,很明显放在这儿都不能使句意通顺流畅,这四个词中只有C项(kids:小孩子)有这样的意思,故我们选择C项为最佳答案
47.A 考查形容词.由上一题的分析,联系上下文的语境,我们不难看出此处语意是:而我们需要一个术语来描述这些看不见的香烟毒素.经过分析,此句是个否定句,应该填上表示看得见的之意的形容词,这四个词中只有A项(visible)有这样的意思,而其余BCD三项依次分别所表达的意思是:看不见,有毒的,具体的,这些意思在这儿都不符合此处的上下文之间语言逻辑,故A项为准确答案.
48.B 考查名词,由语境:该研究报告了全美1500个家庭对待吸烟的态度,我们不难看出此处应该填上表示态度之意的名词,也即是B项,其余ACD项依次分别所表达的意思是:策略,禁止,习惯,很明显放在这儿都不能使句意通顺,故B项为准确答案.
49.D 考查形容词.联系上下文的语境,由上一题的分析,我们容易推理出这一句的语境是:发现绝大多数受访者(烟民与非烟民)都明白二手烟损害儿童健康.很清楚,此处应该填上表示明白清楚之意的形容词,而其余ABC项依次分别所表达的意思是:被告诉,满意的,自信的,这些词语所表示的意思都和这儿的语言逻辑不相契合,而D项的意思是:清楚,明了,有着清醒认识的,故我们选择D项为最佳答案.
50.B 考查动词.联系上下文的语境,经过分析,语意是:大约95%的不吸烟者和84%的吸烟者都同意"婴幼儿吸入父母的二手烟可能致病"的论断.因此,此处应该填上表示同意之意的动词,而ACD项依次分别所表达的意思是:反对,斗争,连接,这些词语所表示的意思都和这儿的语言逻辑不相适合,故我们选择B项(agreed:同意)为最佳答案.
51.A 考查动词.由上一题的分析我们不难看出此处应该填上表示致病之意的动词,致病就是对健康有害,也就是A项和health搭配之后的意思,而其余BCD项依次分别所表达的意思是:毁坏,改进,使…混乱,B项具有很大的迷惑性,但吸三手烟不至于把身体的健康给毁了,CD两项所表示的意思很明显放在这儿都不能使句意通顺,故我们选择A项为最佳答案.
52.C 考查副词.联系全文的语境,及日常生活中的常识,我们容易推理出这一句的语境是:但受访者中却很少有人知道三手烟的危害.经过分析,我们不难看出此处应该填上表示很相、当之意的副词来修饰形容词的比较级fewer,这四个词中只有C项有这样的意思,并且用来修饰形容词的比较级,然后用来代指人,而其余ABD项依次分别所表达的意思是:相当,很,太,并且不用来修饰形容词的比较级,故C项为准确答案.
53.B 考查名词.由上一题的分析我们不难看出此处应该填上表示危害之意的名词,这四个词中只B项(risks:冒险,危害)有这样的意思,而其余ABD项依次分别所表达的意思是:几率,能力,条件,这些意思在这儿都不符合此处的上下文之间语言逻辑,故B项为准确答案.
55.A 考查动词短语.结合上文,只有65%的非烟民和43%的烟民认同该说法.研究者以此作为公众承认三手烟危害的证据.我们容易推理出此处应该填上表示说法、论述之意的名词,这四个词中只有A项有这样的意思,subscribe to赞同,同意
55.B 考查名词.联系上下文的语境,经过分析,语意是:因为这个名称过于新颖,所以调查者换了种说法,提问人们是否同意"昨天有人抽过烟的屋子里的空气今天或现在会对婴幼儿产生危害"的论断.我们不难看出此处应该表示今天和昨天相比,所以填上B项(today:今天),其余ACD项依次分别所表达的意思是:明天,昨天,周末,很明显放在这儿都不能使句意通顺,故B项为准确答案.

点评 完型填空,解题时要抓住文章的脉络,一定要读懂全文,弄清文章要表达的思想,注意前后段落之间的关系.答题中,一定要认真分析,注意选项与上下文的关系,与前后单词的关系.对于一时没有太大的把握的题可以放到最后再来完成,因为有时答案可以从下文内容体现出来.答完后再通读一篇文章,看看所选选项能不能是语句通顺,语意连贯.

14.Although new laws have been passed in some American states to cut down on Distracted(分心的) driving,many accidents and deaths were still related with it,especially using cell phones while driving.Recently the Obama administration is considering disabling cell phones in cars aiming to cut down cell-phone-related road deaths.
Transportation Secretary Ray LaHood,the nation's anti-distracted-driving supporter,said in an interview on November 18that federal officials are looking at technology to disable cell phones inside cars.
"I think it will be done,"LaHood said."I think the technology is there and I think you're going to see the technology become adaptable in automobiles to disable these cell phones-We need to do a lot more if we were going to save lives."
Also on Thursday,the transportation government started a new"Faces of Distracted Driving"video campaign that features people who have been killed or lost their loved ones because of inattentive drivers.The video features heartbreaking stories of children killed,in crashes because of phoning or text messaging,and new videos are expected to be added every few weeks.
A driver is four times more likely to crash while using a mobile phone.More than 5,500people were killed last year by distracted drivers,and another 500,000were injured.LaHood has said it is never safe to talk on a cell phone while driving,hands-free or not,because it can really cause distraction.
Incidentally,a lot of people seem to agree with this viewpoint-a new research shows nearly two-thirds of Americans support a national ban on the use of cell phones while driving,even if the driver is using a hands-free device(装置).But the research didn't ask how people feel about government-issued  mobile phone scramblers or other disabling devices.

63.We can learn from the text that Ray LaHoodB.
A.is in charge of the invention of the technology
B.is strongly for the use of the technology in cars
C.thinks it's easy and practical to invent the technology
D.thinks it's unnecessary to use cell phone while driving
64.The"Faces of Distracted Driving"video campaign aims toC.
A.find out the real drivers who caused the accidents
B.show that most of the victims in car crashes are children
C.make the public aware of the terrible results of distracted driving
D.call on drivers to buy the new device which disables cell phones in cars
65.In the last paragraph,the"mobile phone scramblers"are probablyA.
A.a kind of disabling devices
B.a kind of hands-free devices
C.a new kind of cell phones
D.new devices to help text messaging
66.We can infer from me text thatD.
A.most people realize the harmfulness of distracted driving
B.the disabling devices in cars will be widely used if it is free
C.most people would like to choose hands-free devices while driving
D.the writer is not sure whether disabling devices will be accepted by the drivers.

11.There are still many things that Peter Cooke would like to try his hand at-paper-making and feather-work are on his list.For the moment though,he will stick to the skill he has been delighted to perfect over the past ten years;making delicate and unusual objects out of shells.
   As he leads me round his apartment showing me his work,he points to a pair of shell-covered ornaments(装饰品) above a fireplace.‘I shan't be at all bothered if people don't buy them because I have got so used to them,and to me they're adorable.I never meant to sell my work commercially.Some friends came to see me about five years ago and said,"You must have an exhibition-people ought to see these.We'll talk to a man who owns an art gallery".'The result was an exhibition in London,at which 70 percent of the objects were sold.His second exhibition opened at the gallery yesterday.Considering the enormous prices the pieces command-around£2,000 for the ornaments-an empty space above the fireplace would seem a small sacrifice for Cooke to make.
"I do wish,though,"says Cooke,‘that I'd taken this up a lot earlier,because then I would have been able to produce really wonderful things-at least the potential would have been there.Although the ideas are still there and I'm doing the best I can now,I'm more limited physically than I was when I started.Still,the work that he has managed to produce is a long way from the common shell constructions that can be found in seaside shops.‘I have a miniature(微型的)mind'he says,and this has resulted in boxes covered in thousands of tiny shells,little shaded pictures made from shells and baskets of astonishingly realistic flowers.
Cooke's quest for beautiful,and especially tiny,shells has taken him further than his Norfolk shore:to France,Thailand,Mexico,South Africa and the Philippines,to name but a few of the beaches where he has lain on his stomach and looked for beauties to bring home.
67.What does the reader learn about Peter Cooke in the first paragraph?B
A.He has produced hand-made objects in different materials.
B.He hopes to work with other materials in the future.
C.He has written about his love of making shell objects.
D.He was praised for his shell objects many years ago.

A.is attracted by Cooke's personality
B.realizes he doesn't like Cooke's work at all
C.feels uncertain about giving Cooke his opinion
D.senses that Cooke wants his products to be admired

A.the loss of Cooke's ornaments
B.the display of Cooke's ornaments
C.the cost of keeping Cooke's ornaments
D.the space required to store Cooke's ornaments
70.What does Cooke regret about his work?D
A.He is not as famous as he should have been.
B.He makes less money than he should make.
C.He is less imaginative than he used to be.
D.He is not as skillful as he used to be.
