14.A new study suggests that the more teenagers watch television,the more likely they are to develop depression(情緒低落) as young adults.
The researchers used a national long-term survey of adolescent(青少年的) health to survey the relationship between media(媒體) use and depression.They based their findings on more than 4,000adolescents who were not depressed when the survey began in the year 2000.
As part of the survey,the young people were asked how many hours of television or videos they watched daily.They were also asked how often they played computer games and listened to the radio.Media use was an average of five and one-half hours a day.More than two hours of that was spent watching TV.
Seven years later,in 2007,more than seven percent of the young people had signs of depression.The average age at that time was twenty-one.
The researchers say they did not find any such relationship with the use of other media such as movies,video games or radio,etc.But the study did find that every extra hour of television meant an eight percent increase in the chances of developing signs of depression.Young men were more likely than young women to develop depression given the same amount of media use.
The study didn't explore if watching TV causes depression.But one possibility is that it was taking time away from activities that could help prevent depression.
Last December,the journal Social Indicators Research published a study of activities that help lead to happy lives.Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people.The study found that happy people are more likely to be socially active,to read,to attend religious services and to vote.
25.We can learn from the survey that of all the media useC.
A.computer games are teenagers'favorite        
B.most teenagers prefer to listen to the radio
C.teenagers enjoy watching TV very much       
D.newspaper is not included in the survey
26.According to the passage,what kind of activity may help prevent depression?B
A.Playing computer games.
B.Taking part in sports.
C.Listening to the radio.
D.Watching movies.
27.We can conclude that a teenager shouldB.
A.play more video games instead of watching TV  
B.be active in taking part in outdoor activities
C.be more active in reading and studying        
D.a(chǎn)ttend religious services and care for politics.

分析 本文主要講述媒體使用和抑郁癥的關(guān)系.看電視越多,發(fā)展為抑郁癥的可能性越大.研究發(fā)現(xiàn)參加社交方面活動,如讀書,參加宗教活動和投票選舉等可能會阻止情緒低落.

解答 25--27 CBB
25.C 推理判斷題.根據(jù)第三段Media use was an average of five and one-half hours a day.More than two hours of that was spent watching TV可知,年輕人在媒體上花費的時間為五個半小時,在看電視上花費的時間有2個多小時.故選C.
26.B 細(xì)節(jié)題解題.根據(jù)倒數(shù)第二段But one possibility is that it was taking time away from activities that could help prevent depression及最后一段the journal Social Indicators Research published a study of activities that help lead to happy lives可知,參加活動可以幫助阻止情緒低落.故選B.
27.B 推理判斷題.根據(jù)最后一段Last December,the journal Social Indicators Research published a study of activities that help lead to happy 可知,雜志Social Indicators Research出版了一份可以幫助過快樂生活的活動研究,及下文少看電視,多活動,即戶外活動.故選B.

2.One of India's top engineering schools has restricted Internet access in its boarding houses,saying addiction to surfing,gaming and blogging was affecting students'performance,making them lonely and even suicidal.
Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them."Now,a student doesn't even know who lives two doors away from him because he is so busy on the Internet,"said Prakash Gopalan,dean of Student Affairs."The old dormitory culture of companionship and socializing among students is gone.This is not healthy in our opinion."
IITMumbai,with about 5,000 students,is one of the seven IITs across India which are considered to be among the finest engineering schools in the world.They are also a talent pool for global technology giants.But their hard courses,tough competition and lonely campus lifestyle have taken an effect on students.Depressive and dysfunctional lifestyles are known to be common among IIT students,and at least nine have committed suicide in the past five years.Students have unlimited free Internet access in their boarding houses to help them in their studies,but many also use it to surf,chat,download movies and music,blog and for gaming.
"Starting Monday,Internet access will be banned between 11 p.m.a(chǎn)nd 12:30 p.m.a(chǎn)t IITMumbai's 13 boarding buildings to encourage students to sleep early and to try and force them out of their shells."Gopalan said.But the move has not gone down well with students who say they hate their lives being regulated."Now they will say we need to listen to a lullaby (搖籃曲) to go to sleep."said Rajiv,an electronics student.

9.For centuries,the only form of written correspondence(通信)was the letter.Letters were,and are,sent by some form of postal service,the history of which goes back a long way.Indeed,the Egyptians began sending letters from about 2000BC,as did the Chinese a thousand years later.
Of course,modern postal services now are much more developed and faster,depending as they do on cars and planes for delivery.Yet they are still too slow for some people to send urgent documents(緊急文件)and letters.
The invention of the fax(傳真)machine increased the speed of delivering documents even more.When you send a fax,you are sending a copy of a piece of correspondence to someone by telephone service.It was not until the early 1980s that such a service was developed enough for businesses to be able to fax documents to each other.
The fax service is still very much in use when copies of documents require to be sent,but,as a way of fast correspondence,it has been largely taken the place of by email,Email is used to describe messages sent form one computer user to another.
There are advantages and disadvantages with emails.If you send someone an email,then he will receive it extremely quickly.Normal postal services are rather slow as far as speed of delivery is concerned.
However,if you write something by email,which you might later regret,and send it immediately,there is no chance for second thoughts.At least,if you are posting a letter you have to address and seal(封)the envelope and take it to the post box.There is plenty of time to change your mind.The message is think before you email!
25.We can learn from the text thatC.
A.the postal service has over the years become slower
B.email is less popular than the fax service
C.the postal service has over the years become faster
D.the fax service has a history as long as the postal service does
26.It can be inferred from the text thatC.
A.the fax machine was invented after the 1980s
B.letters have been used in China for about 1,000years
C.the fax service had been fully developed by the 1980s
D.letters have been used in Egypt for about 2,000years
27.In the last paragraph,the writer mentions"think before you email"to show thatA.
A.you'd better not send your email in a hurry
B.you may regret if you don't seal your envelope
C.you may regret before you send something by email
D.you need plenty of time to send an email
28.The text mainly deals withD.
A.the invention of fax machines      
B.the advantage of fax machines
C.the advantage of emails           
D.the progress in correspondence.

3.Many people think of guys as being carefree when it comes to their appearance.But in fact,a lot of guys spend plenty of time in front of the mirror. (36)C.

Exercise regularly.Exercise can help you look good and feel good about yourself.Good physiques (體形) don't just happen.(39)E A healthy habit can be as simple as exercising 20 minutes to one hour three days a week.Working out can also lift your spirits.
(40)B.Your body is just one part of who you are.Your talent for comedy,and all the other things make you unique.So try not to let small imperfections take over.

B.Be yourself.
C.They care just as much as girls do about their body image.

F.The good news is that self-image and body image can be changed.
