17.When your child is supposed to doing homework,they chatting,their friends on Facebook or playing games'!If you want your child to do a good job with their homework and get good grades then you may want to start teaching them that this isn't the best idea.Many studies have shown that multitasking(多任務(wù)化)doesn't work,even though your child is probably proudly claiming they can do ten things at once!Many people believe that they can perform two or more tasks meanwhile,but Dr Edward Hallowell says this is a myth.The reality is that shifting tasks results in poor job performance.
New devices such as smartphone,iPads,games and social networking sites make it very easy to multitask and"attention share"resulting in difficulty focusing on the task at hand such as listening in the classroom or doing homework."Unfortunately.the brain actually rewards kids for multitasking even though performance on every task gets worse and worse.Kids don't know that they are doing worse because they feel better when they multitask,"says Dr Edward Hallowell.
Since the appearance of hand-held devices and social networking sites like Facebook,teachers have noticed a difference in academic performance,critical thinking skills and how information is processed."Multitasking prevents people from gaining a deep understanding of the information they are trying to learn,"says Dr Edward Hallowell.Kids have a difficult time sticking with a"difficult to understand"topic and are more likely to allow themselves to be distracted(分散精力),to tune out and switch over to Facebook or using their cell phones rather than working harder at understanding a difficult subject or problem.In the long run,the shifting of attention by multitasking affects grades.One study showed that kids that use the Internet while in class did poorly on tests resulting in lower grades.
33.What does the passage mainly talk about?C
A.Multitasking is not truth but myth.
B.The multitasking generation.
C.Multitasking results in poor grades.
D.Children are proud of multitasking.
34.What view does the author hold according to the last paragraph?D
A.Multitasking doesn't affect kids'grades in the long run.
B.Kids multitasking are better at shifting attention.
C.Kids should avoid a most difficult problem.
D.The Internet doesn't help kids learn in class.'
35.What is probably discussed in the paragraph following the.passage?C
A.Different attitudes towards multitasking.
B.Why children like multitasking.
C.What to do with children multitasking.
D.The disadvantages of multitasking.

5.It's 10p.m.You may not know where your child is,but the chip does.
The chip will also know if your child has fallen and needs immediate help.Once doctors arrive,the chip will also be able to tell them which drugs are not suitable for little Jonny or Janie.At the hospital,the chip will tell doctors his or her complete medical history.And of course,when you arrive to pick up your child,setting the hospital bill with your health insurance policy will be a simple matter of waving your own chip  the one embedded(植入) in your hand.
To some,this may sound unbelievable.But the technology for such chips is no longer the stuff of science fiction.And it may soon offer many other benefits besides locating lost children or elderly patients.It could be used as credit cards and people won't have to carry wallets anymore.
On the other hand,some are already wondering what this sort of technology may do to the sense of personal privacy and liberty.
"Any technology of this kind could result in abuse of personal privacy,"says Lee Tien,senior staff lawyer for the Electronic Frontier Foundation."If a kid can be tracked,do you want other people to be able to track your kid?It's a double-edged sword."
Applied Digital Solutions,Inc.in Palm Beach,F(xiàn)lorida,says it has recently applied to the Food and Drug Admission for permission to begin testing its device in humans.About the size of a grain of rice,the microchip can be coded with bits of information and embedded in humans under a layer of skin.When scanned by a nearby reader,the embedded chip gives the data.
Most embedded chip designs are so-called passive chips,which give information only when scanned by a nearby reader.But active chips such as the proposed Digital Angel of the future  will give out information all the time.And that means designers will have to develop some sort of power source that can provide a continuous source of energy,yet be small enough to be embedded with the chips.
In addition to technical problems,many suspect that all sorts of legal and privacy issues would have to be cleared as well.

68.By using the example in the first two paragraphs,the author wants to tell us thatC.
A.chips are usually used to locate lost children
B.chips are more convenient than credit cards
C.chips will soon be useful in many aspects of daily lives
D.chips will bring out the issue of abuse of personal privacy
69.What is the attitude of Lee Tien towards the chips?D
A.Negative      B.Positive      C.Indifferent  D.Concerned
70.Which of the following statements about Digital Angel is NOT true?B
A.It will include a chip and a power source.
B.It will be produced and replace passive chips.
C.It will be embedded in humans under a layer of skin.
D.It will give information without being scanned by a reader.
71.It is indicated in the passage that chip producers have to consider the following issues EXCEPTA.
A.financial problems             B.technical problems
C.legal problems                 D.privacy problem.

12.You,re in a department store and you see a couple of attractive young women looking at a sweater.You listen to their conversation:
"I can't believe it-a Lorenzo Betrolla!They are almost impossible to find.Isn't it beautiful?And it's a lot cheaper than the one Sara bought in Rome".
They leave and you go over to see this incredible sweater.It's nice and the price is right. You've never heard of Lorenzo Bertolla,but those girls looked really stylish.They must know.So,you buy it.You never realize that those young women are employees of an advertising agency.They are actually paid to go from store to store,talking loudly about Lorenzo Bertolla clothes.
Every day we notice what people are wearing,driving and eating.If the person looks cool,the product seems cool,too.This is the secret of undercover(暗中進(jìn)行的)marketing.Companies from Ford to Nike are starting to use it.
Undercover marketing is important because it reaches people that don't pay attention to traditional advertising.This is particularly true of the MTV generation-consumers between the age of 18 and 34.It is a golden group.They have a lot of money to spend,but they don't trust ads.
So advertising agencies hire young actors to"perform"in bars and other places where young adults go.Some people might call this practice misleading,but marketing executive Jonathan Ressler calls it creative."Look at traditional advertising.Its effectiveness is decreasing".
However,one might ask what exactly is"real"about of young women pretending to be enthusiastic about a sweater.Advertising executives would say it's no less real than flu ad.The difference is that you know an ad is trying to persuade you to buy something.You don't know a conversation you overhear is just a performance.

64.The two attractive young women were talking loudly so that they could.B
A.get the sweater at a lower price
B.be heard by people around
C.be admired by other shoppers
D.decide on buying the sweater
65.Lorenzo Bertolla isD.
A.a(chǎn) very popular male singer   B.a(chǎn)n advertising agency
C.a(chǎn) clothing company in Rome   D.the brand name of a sweater
66.Which of the following can be inferred from the passage?C
A.The two girls are in fact employed by the Lorenzo Bertolla Company.
B.The MTV generation tends to be more easily influenced by ads.
C.Traditional advertising is becoming less effective because it's too direct.
D.Undercover marketing will surely be banned soon by the government.
67.Which of the following would be the best title for the text?D
A.Two Attractive Shopperb  B.Lorenzo Bertolla Sweaters
C.Ways of Advertising      D.Undercover Marketing.

2.Two new electronic book products (the SoftBook and the PocketBook) have gathered extensive press coverage,including articles in ABC News,the New York Times,San Jose Mercury News,and WIRED.
An electronic book (e-book) is a book-length publication in digital form,consisting of text,images,or both,and produced on,published through,and readable on computers or other electronic devices.Different from a traditional printed book,e-books are born digital.
Being a firm believer in tablet computers for many tasks not involving heavy data entry,I applaud these new designs of the products.In particular,the SoftBook has nice leather binding (封皮),going far beyond the traditional (and boring) industrial design used for other portable computers.The PocketBook has a more traditional industrial design,typical of leading electronic gadgets (小配件).
Unfortunately,neither company mentions their product's screen resolution (分辨率).Low-resolution monitors (including all computer screens until now) have poor readability:people read about 25% slower from computer screens than from printed paper.Scientists believe that only the screen with 300dpi displays has the same reading speed as print.So unless they have much better screens,electronic books will have a problem.
A project called"the last book"is getting much attention,which aims at producing a computer in the form of a folio (對(duì)開本):a set of pages using"digital ink".Users would move forward in the information by turning pages just as they do in a printed book.Hopefully,the scientists will eventually invent a way to make the"digital ink"display characters at a high enough resolution to gain the same reading speed as print.
Even when e-books gain the same reading speed as print,they will still be a bad idea.Page turning remains a bad interface (界面),even when it can be done more conveniently than by clicking the mouse on a"next page"button.
Another problem is that most e-book publishers do not warn their customers about the real meaning of the digital rights management (DRM) tied to their products.Generally they claim that it is meant to prevent copying of the e-book.However,in many cases it is also possible that it will result in the complete denial of access by the purchaser to the e-book.The e-book is tied to a specific computer or device.In these cases,the DRM will usually let the purchaser move the book a limited number of times after which they cannot use it on any additional devices.If the purchaser upgrades or replaces their devices,they may lose access to their purchase.Some forms of the DRM depend on the existence of online services to authenticate (認(rèn)證) the purchasers.When the company that provides the service goes out of business or decides to stop providing the service,the purchaser will no longer be able to access the e-book.

67.From the underlined sentence in Paragraph 3,we know that the writerB.
A.has bought the two new products before
B.likes the special designs of the new products
C.thinks it more convenient to use traditional computers
D.doesn't like the traditional design of portable computers
68.We can learn from the passage thatD.
A.born digital,e-books can only be read on computers
B."digital ink"has gained the same reading speed as print
C.now all the computers are using the screens with 300dpi displays
D.e-books may have slower reading speed compared with printed books
69.Due to the digital rights management,C.
A.the e-book should be tied to a specific device
B.people should upgrade their devices regularly
C.readers are likely to lose access to their purchase
D.only purchasers can download the book without limit
70.This passage mainly talks aboutA.
A.the disadvantages of electronic books   B.the future of electronic books
C.the designs of electronic books         D.two new electronic books.
