题目列表(包括答案和解析)
Scientists are closely concerned with the structure of buildings and with the quality of building materials． The World health Organization （WHO) observes that the introduction of air conditioning and energy conservation （保护) measures have been accompanied by growing problems of indoor air quality． Some pollutants arise from insulation （隔音) products, some from moving cars, and others from modern housing materials． As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important．
Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde （甲醛)． Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes． Paint, lacquer, etc． can also release dangerous gas into indoor air．
Construction materials can cause serious damage, especially when they contain asbestos（石棉）． Asbestos is naturally present in rock formations worldwide． It belongs to a family of mineral substances made up of solid, non-combustible（非易燃品） fiber． These properties make asbestos a highly sought-after construction material． As early as 1931, however, public health officers in the United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer．
The land on which a building is sited may also contribute to pollution． Some kinds of granite or similar rocks contain traces of radium． As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms． The better the homes are insulated, the more is the dangerous gas in indoor air． The main effect of this dangerous gas on health is to increase the risk of lung cancer．
1.What is the main idea of the passage?
A．Some building materials pollute indoor air．
B．Some factors cause indoor air pollution．
C．Asbestos can cause lung cancer．
D．The land on which houses are built contributes to indoor pollution．
2.Why are Europeans particularly concerned with building materials?
A．Lots of building materials there are radioactive．
B．They stay home up to 90% of their lives．
C．They have a high rate of lung cancer．
D．They spend most of their time indoors．
3.Why is asbestos a sought-after building material?
A．It is a kind of insulation foam．
B．Asbestos will not give out dangerous gas．
C．This material is not easy to catch fire．
D．It is rarely present in rock formations．
4.Why should we be careful about the land on which a building is to be sited?
A．To determine whether the land is firm enough for a building to be sited on．
B．To make sure that the land contains no radioactive material．
C．To make certain that the land releases no formaldehyde or other gases．
D．To check whether it contains any combustible materials．
Ban the Band（乐队）?
Every year, our school has a dance for all the students. It’s a little funny seeing friends in clean shoes and trousers or colorful 36 , instead of the usual school uniform.
Most of us think the dance is great 37 －even the teachers enjoy being there. 38 , two weeks ago someone said that there would be no 39 band this year only CDs.
“I don’t 40 it!” Amy cried out during the lunch break.
“Someone said the school couldn’t 41 a band, and they think it’s too noisy anyway,” added Daniel.
“Well, I don’t think it’s 42 enough without a band!” declared Angela, “and I’m going to see what can be done.”
Angela was as good as her 43 . In the afternoon she went to see the school headmaster who agreed to give the 44 some more thought. And he suggested that one 45 for having a band was to increase the price of each ticket from $5 to $10. Angela had to 46 out whether the students would like to do that.
“I need all of you to help me,” she 47 to our group before school the next day. “Mr. Berry gave me a list of all the names, and suggested we ask each one their 48 about the band and the extra cost.”
49 the day we asked around as Angela suggested, and wrote down people’s feelings about the band and the cost. We were amazed how much 50 there was for the band and everyone agreed to pay the extra $5.
“I’m surprised,” smiled Mr. Berry, when we gave him the 51 . “I really thought that only a few people 52 their band and that the cost would be too high. OK, Angela, your next 53 is to find a good band and line them up for the dance.”
Angela was all smiles and 54 the news to Amy and Daniel. “You’re 55 ,” smiled Daniel to Angela as he thought how close they came to having a less than perfect dance.

Hi! Have you ever suddenly felt that someone you knew was in trouble — and was he? Have you ever dreamed something that came true later? Maybe you have ESP (超感觉知觉).
ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here's an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I saw him sitting in the chair!" Just then, a telegram came. The woman's father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what's behind these strange mental messages. Here
's another example—one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, "There's room for one more." The man felt the driver seemed dead, so he ran away. The next day, when the ma
n was getting on a crowded bus, the bus driver said, "There's room for one more."
Then the man saw that the driver's face was the same face he had seen in the dream. He wouldn't get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.
【小题1】According to the passage, the author believes that the sixth sense is ________.
| A．in existence | B．imaginative | C．not real | D．impossible |
| A．about events before they happen |
| B．about events after they happen |
| C．about events that are happening some distance away |
| D．A and C |
| A．learn how people tell lies | B．know more about human dreams |
| C．know more about human mind | D．learn how strange things happen |
| A．things that may not happen | B．things that happen in a dream |
| C．things that must happen | D．things that happen by accident |
A few months ago, it wasn't unusual for 47-year-old Carla Toebe to spend 15 hours per day online. She'd wake up early, turn on her laptop and chat on Internet dating sites and instant-messaging programs – leaving her bed for only brief breaks. Her household bills piled up, along with the dishes and dirty laundry, but it took constant complaints from her four daughters before she realized she had a problem.
"I was starting to feel like my whole world was falling apart – kind of slipping into a depression," said Carla. "I knew that if I didn't get off the dating sites, I'd just keep going," detaching (使脱离) herself further from the outside world.
Toebe's conclusion: She felt like she was "addicted" to the Internet. She's not alone.
Concern about excessive Internet use isn't new. As far back as 1995, articles in medical journals and the establishment of a Pennsylvania treatment center for overusers aroused interest in the subject. But as reliance on the Web grows, there are signs that the question is getting more serious attention: Last month, a study published in CNS Spectrums claimed to be the first large-scale look at Internet overuse. The American Psychiatric Association may also consider listing Internet addiction in the next edition. And scores of online discussion boards have popped up, on which people discuss negative experiences tied to too much time on the Web.
The new CNS Spectrums study was based on results of a nationwide telephone survey of more than 2,500 adults. Like the latest survey, this one was conducted by Stanford University researchers. About 6% of respondents reported that "their relationships suffered because of excessive Internet use." About 9% attempted to conceal "nonessential Internet use," and nearly 4% reported feeling " still occupied by the Internet when offline."
"The Internet problem is still in its early stage," said Maressa Orzack, a Harvard University professor. No single online activity is to blame for excessive use, he said. "They're online in chat rooms, checking e-mail, or writing blogs. The problem is not limited to porn (色情) or gambling websites.”
“Excessive Internet use should be defined not by the number of hours spent online but in terms of losses.”said Maressa Orzack. "If it's a loss where you're not getting to work, and family relationships are breaking down as a result, then it's too much."
Since the early 1990s, several clinics have been established in the U. S. to treat heavy Internet users. They include the Center for Internet Addiction Recovery and the Center for Internet Behavior.
The website for Orzack's center lists the following among the psychological symptoms of computer addiction:
● Having a sense of happiness or excitement while at the computer.
● Longing for more and more time at the computer.
● Neglect of family and friends.
● Feeling empty, depremssed or irritable when not at the computer.
● Lying to employers and family about activities.
● Inability to stop the activity.
● Problems with school or job.
Physical symptoms listed include dry eyes, backaches, skipping meals, poor personal hygiene (卫生) and sleep disturbances.
“People who struggle with Internet overuse maybe depressed or have other mood disorders.” Orzack said. When she discusses Internet habits with her patients, they often report that being online offers a "sense of belonging, and escape, excitement and fun," she said. “Some people say relief…because they find themselves so relaxed.”
Some parts of the Internet seem to draw people in more than others. Internet gamers spend countless hours competing in games against people from all over the world. One such game, called World of Warcraft, is cited on many sites by posters complaining of a "gaming addiction."
Andrew Heidrich, an education network administrator from Sacramento, plays World of Warcraft for about two to four hours every other night, but that's nothing compared with the 40 to 60 hours a week he spent playing online games when he was in college. He cut back only after a full-scale family intervention (干预), in which relatives told him he'd gained weight.
“There's this whole culture of competition that sucks people in with online gaming, ”said Heidrich, now a father of two. People do it at the expense of everything that was a constant in their lives." Heidrich now visits websites that discuss gaming addiction regularly “to remind myself to keep my love for online games in check”.
Toebe also regularly visits a site where posters discuss Internet overuse. In August, when she first realized she had a problem, she posted a message on a Yahoo Internet addiction group with the subject line:“I have an Internet Addiction.”
“I'm self-employed and need the Internet for my work, but I'm failing to accomplish my work, to take care of my home, to give attention to my children,”she wrote in a message sent to the group. “I have no money or insurance to get professional help; I can't even pay my loan and face losing everything.”
Since then, Toebe said, she has kept her promise to herself to cut back on her Internet use. "I have a boyfriend now, and I'm not interested in online dating," she said by phone last week. "It's a lot better now."
1. What eventually made Carla Toebe realize she was spending too much time on the Internet?
A. Her daughter's repeated complaints.
B. Tiredness resulting from lack of sleep.
C. The poorly managed state of her house.
D. The high financial costs adding up.

Our Future Homes
What kinds of homes will we live the future? Nobody can be sure, architects, and scientists are new ideas now.
Some architects are thinking about whole cities under huge glass domes. Of course, complicated heating and systems will be necessary to control the climate in the domes. , there will never be any rain snow, and the temperature will be always .
Perhaps everyone will live in vertical（立体的） . High rises are so large that they can contain all the necessities of life. Since vertical cities will use land than horizontal cities, and provide homes for more people, they will be for small countries that have populations.
Another idea that will be helpful to countries (and island countries) is
the city. Monaco has already built homes, stores, and offices the water of the Mediterranean Sea. And a Japanese has made a plan for constructing buildings on bridges over Tokyo Bay.
There are some people who think we will go back to living in . But the caves of the future will be quite the caves of the Stone Age. Computers will control light and climate. Farms and parks will be on the land the cave city. When people want to go to the country or to a park, a short ride in will take them there.
