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.

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.
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.
