7.Cell Phones:Hang Up or Keep Talking?
Millions of people are using cell phones today.In many places it is actually considered unusual not to use one.(31)CThey find that the phones are more than
a means of communication----having a mobile phone shows that they are cool and
connected.
The explosions around the world in mobile phone use make some health professionals worried.Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried about the negative publicity of such ideas.(32)F
On the other hand,why do some medical studies show changes in the brain cells of some people who use mobile phones?Signs of change in the tissues of the brain and head can be detected with modern scanning(扫描)equipment.In one case,a traveling salesman had to retire at a young age because of serious memory loss.(33)DHe would often forget the name of his own son.This man used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of years.His family doctor blamed his mobile phone use,but his employer's doctor didn't agree.
(34)G The answer is radiation.High-tech machines can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is some radiation,but they say the amount is too small to worry about.
As the discussion about their safety continues,it appears that it's best to use mobile phones less often.(35)AUse your mobile phone only when you really need it.Mobile phones can be very useful and convenient,especially in emergencies.In the future,mobile phones may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile phone too often.
A.Use your regular phone if you want to talk for a long time.
B.They will possibly affect their benefits.
C.In many countries,cell phones are very popular with young people.
D.He couldn't remember even simple tasks.
E.What do the doctors worry about?
F.They say that there is no proof that mobile phones are bad for your health.
G.What is it that makes mobile phones potentially harmful?

分析 手机对我们现代人而言意义重大,然而它们有利也有弊,我们要合理使用,而且要注意安全.

    I've dreamed of becoming a writer since I was a teenager.But (61)it isn't easy to get a book of mine published.(62)Though\Although I've tried hard,none of my books have been published.This is really (63)upsetting (upset).

16.Internet data shows that younger adults have become the main audience crazy about changing their appearance.Once the world of the female in her fifties,plastic surgery(整形手术) has become the focus of the younger Internet users.
The recent death of Stephanie Kuleba,an 18-year-old high school cheerleader who died as a result of plastic surgery,brought our attention to the fashion of becoming a more"ideal"body among teenagers.In fact,search data confirms this phenomenon.One of the most popular sites visited from the search term"plastic surgery"is the official site of the American Society of Plastic Surgeons (www.plastic surgery.org).Over 25% of the visitors,which is up from 19.6% two years ago,fell within the 18to 24years old.
Plastic surgery has become an American obsession (痴迷).Checking other countries,such as the UK and Australia,the 18to 24-year-old's being interested in plastic surgery is an obvious US phenomenon.Unlike the other groups who visit sites related to diseases and keeping healthy,younger Internet users rush to sites that deal with personal appearance,such as those focused on body-building,weight loss and skin-care,and obviously plastic surgery.
While television on surgery may be driving the interest of a younger audience,one factor appears to be a key in preventing such teens from changing their bodies:the failing U.S.economy.There has been a decline in all plastic surgery topics over the last year.While older age continue to search for information on procedures such as liposuction(抽脂),it's younger Internet users who in tough economic times are focusing on improving their outer beauty,though at a discount price.

32.Why does the author mention the death of the 18-year-old cheerleader?D
A.To show cheerleaders pay more attention to their appearance.
B.To warn people that plastic surgery is not as safe as it is said to be.
C.To prove the fact that people will pursue beauty at any cost.
D.To draw attention to the issue of young people having plastic surgery.
33.While young people are surfing on the Internet,they are very interested inD.
A.how to be physically and mentally healthy.
  B.how to make themselves look young.
C.how to prevent and cure diseases.
D.how to have more attractive appearance.
34.What may affect young people's decision on whether to have plastic surgery?B
A.The safety of the operation
B.The total expense of the surgery.
C.The need for having the operation.
D.The results of the surgery.
35.What can we learn from the last paragraph?A
A.Americans,old or young,are crazy about plastic surgery.
B.Liposuction is the most expensive plastic surgery.
C.Outer beauty means more to young people than inner beauty.
D.Young people often get discount when having plastic surgery.

11.As Internet users become more dependent on the Internet to store information,are people remember less?If you know your computer will save information,why store it in your own personal memory,your brain?Experts are wondering if the Internet is changing what we remember and how.
    In a recent study,Professor Betsy Sparrow conducted some experiments.She and her research team wanted to know the Internet is changing memory.In the first experiment,they gave people 40 unimportant facts to type into a computer.The first group of people understood that the computer would save the information.The second group understood that the computer would not save it.Later,the second group remembered the information better.People in the first group knew they could find the information again,so they did not try to remember it.
    In another experiment,the researchers gave people facts to remember,and told them where to find the information on the Internet.The information was in a specific computer folder (文件夹).Surprisingly,people later remember the folder location better than the facts.When people use the Internet,they do not remember the information.Rather,they remember how to find it.This is called"transactive memory (交互记忆)".
    According to Sparrow,we are not becoming people with poor memories as a result of the Internet.Instead,computer users are developing stronger transactive memories; that is,people are learning how to organize huge quantities of information so that they are able to access it at a later date.This doesn't mean we are becoming either more or less intelligent,but there is no doubt that the way we use memory is changing.
32.The passage begins with two questions toA.
A.introduce the main topic            
B.show the author's attitude
C.describe how to use the Internet.
D.explain how to store information
33.What can we learn about the first experiment?C
A.Sparrow's team typed the information into a computer.
B.The two groups remembered the information equally well.
C.The first group did not try to remember the formation.
D.The second group did not understand the information.
34.In transactive memory,peopleD.
A.keep the information in mind        
B.change the quantity of information
C.organize information like a computer
D.remember how to find the information
35.What is the effect of the Internet according to Sparrow's research?A
A.We are using memory differently.
B.We are becoming more intelligent.
C.We have poorer memories than before.
D.We need a better way to access information.
