题目内容

3．A Dutch artist and designer has come up with a device which he hopes will get rid of pollutants from Beijing's smog skies，creating clean air for the city's mask-wearing people．An electromagnetic （电磁）field will pull particles（微粒） in the smog to the ground where they can be easily cleaned．"
It's like when you have a balloon which has static（静电） and your hair goes toward it．Same with the smog，"says artist Daan Roosegaarde．
His studio has reached an agreement with the Beijing government to test the technology in one of tile capital's parks．
With its skies regularly covered by dirty gray smog，Beijing this week announced a series of emergency measures to handle the problem．
Roosegarde says an indoor model device has already proven it works and is confident that the results-with the help of a team of scientists and engineers-can be replicated outside．
"Beijing is quite a good place because the smog in Beijing is quite low．It lies in a valley so there's not so much wind．It's a good environment to explore this kind of thing．"
"We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again．"
Roosegaarde acknowledges that projects like this are a way of drawing attention to the problem，rather than a practical solution to Beijing's awful air pollution．
"This is not the real answer for smog．The real answer has to do with clean cars，different industry and different lifestyles．"
However，he hopes the project will make a"fundamental statement"by allowing the city's people to realize the difference between breathing clean and smog-filled air．

25．The device works byB．
A．helping keep the particles out with more masks
B．pulling pollutants to the ground with an electromagnetic field
C．absorbing hair with a balloon with static
D．creating clean air and let it out into the sky
26．According to the passage，C．
A．the Beijing government has agreed to use the technology in Beijing
B．they have provn the results of the device both indoors and outdoors
C．the results of the air-cleaning device can be expectable
D．the Beijing governmenthas never done anything to handle the air pollution
27．What does Roosegaarde really mean by saying"Beijing is quite a good place…"？C
A．The air pollution in Beijing is not quite serious．
B．The weather in Beijing is good for foreigners to live in．
C．Beijing is quite fit for using the air-cleaning device．
D．It is easy to get the top of the smog in Beijing．
28．Roosegaarde appeals to people in Beijing toA．
A．pay attention to air pollution and solve the problem finally
B．invent more devices to clean the smog in Beijing
C．drive modern cars and try different lifestyles
D．realize how serious the pollution they're facing is．

分析一位荷兰艺术家兼设计师发明了一种装置，他希望借此装置能够为北京烟雾笼罩的天空清除污垢，为那些戴着口罩的北京市民创造新鲜的空气．

解答 25．B．细节理解题．根据文意An electromagnetic field（电磁场） will pull particles（微粒） in the smog to the ground where they can be easily cleaned可知这种装置的工作原理是通过铜线圈制造的电磁场可以将漂浮于烟尘中的颗粒物吸附到地面上，很轻易的被清理干净，所以答案是B
26．C．判断推理题．根据文意We'll be able to purify the air and the challenge is to get the top of the smog so you can see the sun again．我们可以净化空气，但真正的挑战在于，要将烟尘清除彻底，重见天日可知装置在净化空气，美化环境方面是很令人期待的，所以答案是C．
27．C．判断推理题．根据文意Beijing is quite a good place because the smog in Beijing is quite low．It lies in a valley so there's not so much wind．It's a good environment to explore this kind of thing北京的地形和气候条件都很适合．空中的烟尘高度很低，而且它地处谷地，空气流动性不强．这种地形气候条件很适合测试该装置，所以答案是C．
28．A．推理判断题．最后一段Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dir学科网（www．zxxk．com）--教育资源门户，提供试卷、教案、课件、论文、素材及各类教学资源下载，还有大量而丰富的教学相关资讯！ty air pollution but also to make people pay attention to the environment problem．描述，可知他不仅希望解决污染问题还希望人们注意环境问题．故选A．

点评考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．

15．I am now truly filled withhappiness（快乐） that I am a devoted friend and helper of the human race．

11．I live in a city，and I like quiet life．I hate nosy （爱管闲事的） neighbors but it's very unlucky that I had one for myself．They moved in a couple of months ago and although I never felt that they were a strange family，I've always hated the way they get"too close"to me，my house，my garden，and even my garbage cans．
One day，my neighbors were mowing their lawn （草坪）．My garbage cans were near their lawn．For some strange reason，I found the wife looking through my garbage cans．I felt angry but since they were from a different culture，I thought that maybe it was"normal"from their ideas．
That afternoon，the couple knocked on my front door．When I opened，they gave me a plastic bag．Inside were my old daily bills，credit cards and bank statements，and an old birthday card that my old uncle sent．They said that they were returning them to me because these documents contained very private information that may be used by others．
I've heard of it before．I asked them how those documents can be used by others and they started telling me their very own experience，which forced them to leave their home and move next door to us．The wife told me that she never destroyed the bills．They also had a"nosy neighbour"who looked through their garbage cans which they actually thought was pretty strange．Little did they know that this"nosy neighbor"was collecting their personal information from their rubbish．Then all their money was taken out from the bank by their neighbor．
It was a very painful experience for all of them and they wanted to leave it all behind so they left．I was very thankful．They were not nosy neighbors．They simply didn't want us to experience the same thing that they did．

Trying to come to a decision complete on your own can be risky．Some decisions are so important that they shouldn't made without talking to others first．There have several advantages if you consult the persons you trust．For one thing，they can give you valuable advice and they may point out some things you may have been overlooked．For another，friends may stop you from make big mistakes．
When consulting others about importance decisions，you should keep two things in mind．The first one is that you need to find someone whom you respected enough to trust their judgment．The second thing to consider is how to do if you disagree with this person．Maybe turning to a third or fourth person for help is the best option．In a word，making any big decision alone can lead in problems．Talking to friends or family members first are always a good idea．

Her mother ran a boardinghouse in Galveston，a seaside town near Houston，Texas．She was cleaning out the attic（阁楼） one day when she came across an old dusty manuscript（手稿）．On its top page were the words，"By O．Henry．"It was a nice story，and she sent it to her daughter at SMU，who showed it to my father．My father had never read the story before，but it sounded like O．Henry，and he knew that O．Henry had once lived in Houston．So it was possible that the famous author had gone to the beach and stayed in the Galveston boardinghouse，and had written the story there and left the manuscript behind by accident．My father visited an O．Henry expert at Columbia University in New York，who authenticated the story as O．Henry's．
My father then set out to sell it．Eventfully，he found himself in Des Moines，meeting with Gardner Cowles，a top editor at the Des Moines Register．Cowles loves the story and bought it on the spot．My father took the money to the girl．It was just enough for her to have the operation she so badly needed．

Every four years on November 8, the American people will vote for the next U. S. president. Before election day, people following the presidential campaign will see many polls (民调). A poll is a public opinion study. Research organizations ask people questions about the candidates to find out who they support.

For example, one of the poll is run by a professor at a university in the U.S. state of Connecticut. People who work for the polling service call likely voters on the telephone.

How can one poll be so different from others? Here are some things to remember when you are looking at polls:

Some polls target specific groups of people. Many polls make sure they collect many different opinions. Sometimes, however, polling organizations receive money from groups that support a specific political issue. It is important to look at which group carried out the poll along with the results.

A poll's method is important

Some polls are using new technology. Traditionally, polls are done over the phone. But that is slowly changing. Many polls are now done online. While online polls can produce good information, it is sometimes hard to reach as many different types of people over the Internet.

Also important the size of the poll. Try to find out how many people were polled before believing its results.

Polls are not predictions(预测)

Polls only show how people feel at one moment in time. They do not show what will happen in the future. Public opinion may change before the general election on November 8. Some things that could change the opinions of voters include: the debates on television, the release of the candidates’ tax or medical records, and unexpected illnesses.

1.What do political polls in the U. S. try to do?

A. Call on people to be active in the election.

B. Help political parties to win the election.

C. Find out the support rate in the election.

D. Affect people's opinions in the election.

2.What do you know about polling organizations?

A. Some serve for certain groups. B. They all collect different opinions.

C. They all make money from their polls. D. All of them try to find the correct results.

3.What is the disadvantage of polls done online?

A. People may refuse to respond. B. Results sometimes lack of representation.

C. Only the young give their ideas. D. People refuse to tell their true thoughts.

4.What can be a suitable title for the text?

A. Effects of Political Polls in the U. S..

B. Various Kinds of Political Polls in the U. S..

C. Ways to Carry Out Political Polls in the U. S..

D. Things to Know About Political Polls in the U. S..
