B

The Internet is sometimes described as big computing power.But this power has to come from somewhere.Data centers(数据中心)are buildings full of servers.These powerful computers store，process，and move information.They make the Web work.

Tasks traditionally done with software，which is stored on a personal computer，are now increasingly offered as services on the Internet.Google Apps，for example，can work without the need for special software.Other companies，including Salesforce.com and Microsoft，also offer software as a service.

Rich Miller is an editor of the Data Center Knowledge.He says that computing power needs another kind of power which also has to come from somewhere.Data centers need energy not only to operate their servers but to cool and protect their systems.

The Environmental Protection Agency says the United States has about ten thousand data centers.It also says that they use almost two percent of the country’s electricity.

The amount and cost of energy used by data centers is the subject of growing concern.Using wind power or some other renewable(可再生的)energy for data centers could help the situation.Another answer is to make servers more energy­efficient.

Still another solution may come from virtualization.This lets one server work like several.A server usually runs a single operating system，like Linux or Windows.Virtualization lets both run at the same time.

Rich Miller at Datacenterknowledge.com says the need for data centers will only increase as the Internet becomes more central to everyday life.

40.According to the first paragraph，all of the following statements about servers are true EXCEPT that________.

A.they are people in the data centers

B.they make the Web work

C.they send information to Internet users

D.they are powerful computers in the data centers

答案　A

解析　简单判断题。根据“These powerful computers store，

process，and move information.”可知servers在这里是指服务器，即功能很大的电脑，而不是指人。

41.Which of the following may NOT offer software as a service?

A.Google Apps.

B.Salesforce.com.

C.Microsoft.

D.Datacenterknowledge.com.

答案　D

解析　简单判断题。通读第二段，可知Google Apps、Salesforce.com以及Microsoft都给用户提供软件服务，文章并没有说Datacenterknowledge.com也为用户提供软件服务。

42.We can learn from the passage that________.

A.data centers often stop working

B.data centers use a lot of energy every day

C.there are about ten thousand data centers in the world

D.people no longer store software on their computers

答案　B

解析　推理判断题。根据第四段的“they use almost two percent of the country’s electricity.”以及后文提到的越来越多的人为数据中心消耗能量担忧可知其消耗能量很大。

43.In the writer’s opinion，which of the following may NOT be a good way to solve the energy problem?

A.By using wind power.

B.By making servers more energy­efficient.

C.By letting one server work like several.

D.By asking people to rely on the Internet less.

答案　D

解析　细节理解题。根据最后一段的“the need for data centers will only increase as the Internet becomes more central to everyday life.”可知人们只会更多地依赖于网络，故可推断作者不会认为人们减少对网络的依赖是解决能源问题的办法。

C

Do you know that girls are seven times more likely than boys to be unhappy and twice more likely to commit suicide(自杀)and that girls are three times more likely than boys to have a negative attitude?Twenty percent of the girls in the US between the ages of 12 and 17 drink alcohol(酒)and smoke cigarettes.

So what is mental(心理的)health?Mental health is how we think，feel，and act in order to face life’s problems.

A young girl’s mental health affects her daily life and future.Like physical health，mental health is important at every stage of life.Caring for and protecting a young girl’s mental health is important to ensure that she grows up to become the best she can be.

Many children experience mental health problems that are painful and can be serious.Mental health problems affect at least one in every five young people at any given time.Unluckily，about two thirds of all young people with mental health problems are not getting the help they need.Mental health problems can lead to school failure，alcohol or other drug abuse(滥用)，family violence，or even suicide.

There are many signs that may point to a possible mental health problem in a child or teenager.If you are worried about a child or have any questions，look for help at once.Talk to your doctor，a school teacher，or other mental health experts who are trained to know whether your child has a mental health problem.You can also call 1­800­789­2647 for a list of warning signs.

44.What is implied in the first paragraph?

A.More and more girls are committing suicide.

B.Boys are usually physically stronger than girls.

C.Girls are more likely to have mental health problems than boys.

D.Children in America are lacking in parental care.

答案　C

45.In the author’s opinion，________.

A.mental health is more important than physical health

B.mental health is important no matter how old you are

C.people with mental health problems will never succeed

D.it’s easier for children to have mental health problems than adults

答案　B

解析　细节理解题。根据第三段的“mental health is important at every stage of life.”可知在作者看来，不管人的年纪多少，心理健康都很重要。

46.According to the passage，which of the following people would most probably call 1­800­789­2647?

A.People who are sure they have mental health problems.

B.Children who have mental health problems and want help.

C.Parents who want to know whether their children are doing well at school.

D.Parents who want to know whether their children have mental health problems.

答案　D

解析　推理判断题。根据最后一句的“for a list of warning signs”可知拨打这个电话号码可以查询心理健康问题的一些征兆，故可推断那些想知道自己的孩子有没有心理健康问题的父母最有可能拨打这个电话号码。

47.The purpose of this passage is to________.

A.tell parents what to do if they find that their children have mental health problems

B.explain why so many children have mental health problems

C.tell people how bad it is to have mental health problems

D.ask parents to pay more attention to their children’s mental health

答案　D

解析　作者意图题。根据第四段的“Unluckily，about two thirds of all young people with mental health problems are not getting the help they need.”可知目前很多父母对孩子的心理健康问题不够重视，作者在文章中强调了心理健康的重要性以及心理健康问题的危害性，其目的是希望父母们能更加重视孩子们的心理健康。

D

It is true that the first Olympic Games of the modern times in 1896 were not open to women.Baron Pierre de Coubertin，who gave new life to the Games，was very much a man of  his time.He didn’t like women showing up for the Games.But since this time，things have changed.History shows that the number of women participating_in the  Olympic Games has been increasing over the years, since their first participation in the 1900 Olympic Games and especially in the last 30 years.This development is of social，political and cultural significance(意义).

The progress is the result of the cooperation(合作)of the entire Olympic Movement and of proper measures that the International Olympic Committee (IOC)，International Sports Federations (IFs)，and  National Olympic Committees (NOCs) have taken.Especially in the last 20 years，the IOC has enlarged the women’s program at the Olympic Games，in cooperation with IFs and the Organizing Committees for the Olympic Games (OCOGs).This development was further strengthened(巩固)by the IOC’s decision that all sports must have women’s events.The IOC also started to work on increasing the number of women at leadership level in sport in 1981.Former President Juan Antonio Samaranch，who wanted to have women as IOC members，made a great contribution(贡献).

Many sports volunteers have worked to increase the number of women joining in the Olympic Games.This progress has been made also thanks to the strong determination of women from different countries of the world who have worked to make sure women are fully represented in all sports.

48.The underlined part “participating in” in the first paragraph can be replaced by “________”.

A.getting close to   B.taking part in

C  calling for       D.taking over

B.Baron Pierre de Coubertin was very famous when he was alive

B.How more and more women were able to join in the Olympic Games.

根据下表所提供的信息，写一篇报告，描述奥运会给你校学生生活带来的变化。

奥运会之前 奥运会之后

学校每周两节体育课，并且有时被文化课占用 每天一小时体育活动课，师生一起开展户外活动

学生只顾学习，忽视运动 认识到身体好可以促进学习

注意：词数100左右。

参考词汇：忽视 neglect

【参考范文】

As the form reflects，with the 2008 Olympic Games successfully held in Beijing，some positive changes have taken place in our school.

Before that，each week，only two PE lessons were scheduled，during which sometimes we were actually having lessons such as Chinese，Math，Physics and so on.Most students mainly cared for their studies and always neglected physical training.

Luckily，the school life has completely changed since the Olympics!Nowadays，in contrast，we spend more of our time doing physical exercise.Every day we are given one hour to organize some outdoor events along with our teachers.Having realized that good health can，in turn，help us to learn more productively，most of our fellow students begin to pay close attention to our physical health.
