2.When you say that someone has a good memory,what exactly do you mean?Are you saying that the person has fast recall or that he or she(51)D information quickly?Or maybe you just mean that the person remembers a lot about her or his childhood.The truth is that it is (52)C to say exactly what memory is.Even scientists who have been studying memory for decades say they are still trying to(53)A exactly what it is.We do know that a particular memory is not just one thing stored somewhere in the brain.(54)B,a memory is made up of bits and pieces of information stored all over the brain.Perhapsthe best way to(55)C memory is to say that it is a process-a process of recording,storing,and getting back information.Practice and repetition can help to(56)D the pieces that make up our memory of that information.
Memory can be (57)B affected by a number of things.(58)A nutrition can affect a person's ability to store information.Excessive alcohol use can also weaken memory and cause permanent (59)Dto the brain over the long term.A vision or hearing problem may affect a person's ability to notice certain things,thus making it(60)Cto register information in the brain.
When people talk about memory,they often(61)A short-term memory and long-term memory.If you want to call a store or an office that you don't call often,you look in the telephone book for the number.You dial the number,and then you forget it!You use your short-term memory to remember the number.Your short-term memory lasts about 30seconds,or half a minute(62)B,you don't need to look in the telephone book for your best friend's number,because you already know it.This number is in your long-term memory,which(63)D information about things you have learned and experienced through the years.
Why do you forget things sometimes?The major reason for forgetting something is that you did not learn it well enough(64)C.For example,if you meet some new people and right away forget their names,it is because you did not(65)B the names at the first few seconds when you heard them.

61.A  62.B  63.D  64.C  65.B51.D 考查動詞詞義辨析collect收集;process處理,加工;publish出版;absorb吸收,理解.當(dāng)說一個人有很好的記憶力時,到底是什么意思?是說這個人可以很快地回憶起某件事情還是能很快的理解信息?
52.C 考查形容詞詞義辨析necessary必要的;important重要的;difficult困難的;convenient方便的.事實是很難說清楚到底記憶力是什么.
53.A 考查固定用法figure out解決,算出;take out拿出來;put out撲滅;give out分發(fā),用完,筋疲力盡.甚至連研究了幾十年記憶力的科學(xué)家們也說他們還在努力去解決記憶力到底是什么.
54.B  考查副詞詞義辨析after all畢竟;instead代替,而是;by contrast相比之下;besides而且.我們知道的是特定的記憶不僅僅是儲存在大腦的某個地方,而是由存在整個大腦中的信息碎片組成的.
55.C 考查動詞詞義辨析 recall召回,回憶起;refresh恢復(fù)精神;describe描述;decrease減少.或許描述記憶力最好的方式是說它是一個過程,一個記錄,儲存和找回信息的過程.
56.D 考查動詞詞義辨析 lose失去;organize組織;identify確定,鑒定;strengthen加強.練習(xí)和重復(fù)可以幫助加強組成記憶的信息碎片.
57.B  考查副詞詞義辨析positively肯定地;negatively消極地;actively積極地;directly直接地.記憶力可能會受很多事情的消極影響.
58.A 考查形容詞詞義辨析 poor貧窮的,貧乏的;adequate充足的;special特殊的;various各種各樣的.缺乏營養(yǎng)會影響一個人儲存信息的能力.
59.D 考查名詞詞義benefit利益;offence犯罪,過錯,攻擊;effect效果;damage損害,損壞.過度飲酒也會弱化記憶力,長期下來回造成永久性的大腦損傷.
60.C  考查形容詞詞義辨析視覺或聽力問題會影響注意某些特定事情的能力,這樣也使信息在大腦中的儲存更加困難.
61.A考查固定用法 refer to指的是;apply for申請;come across偶然遇到;break down發(fā)生故障.當(dāng)人們提到記憶時,往往指的是短期記憶和長期記憶.
62.B  考查副詞詞義辨析furthermore此外,而且;however然而;consequently因此,結(jié)果;otherwise否則.下文與上文之間表示轉(zhuǎn)折,對比,所以用however.
63.D 考查動詞詞義辨析leak泄露;transmit傳輸,傳播;check檢查;store儲存.電話號碼是你的長期記憶,長期記憶就是多年來你已經(jīng)了解的事情.
64.C 考查固定用法為什么有時會遺忘呢?遺忘主要是因為一開始就沒有學(xué)好.
65.B  考查動詞詞義辨析restore恢復(fù),修復(fù);record記錄;replace代替;respond反應(yīng).如果你遇到一些人,馬上就忘記了他們的名字,那是因為你在聽到他們名字的前幾秒鐘根本就沒有記下來.

點評 完型填空,解題時要抓住文章的脈絡(luò),一定要讀懂全文,弄清文章要表達的思想,注意前后段落之間的關(guān)系.答題中,一定要認真分析,注意選項與上下文的關(guān)系,與前后單詞的關(guān)系.對于一時沒有太大的把握的題可以放到最后再來完成,因為有時答案可以從下文內(nèi)容體現(xiàn)出來.答完后再通讀一篇文章,看看所選選項能不能是語句通順,語意連貫.

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(裝置).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(chǎn) kind of disabling devices
B.a(chǎn) kind of hands-free devices
C.a(chǎn) 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(裝飾品) 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.
68.When looking round his apartment,the wrierA.
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
69.The‘small sacrifice'in Paragraph 2 refers toA.
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.
