There was one thought that air pollution affected only the area immediately around large cities with factories and heavy automobile traffic. At present, we realize that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the east of the United States and brought health warnings in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be infected by air pollution. Some scientists consider that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels (coal and oil) is creating a “greenhouse effect”— conserving heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be in water.
Another view, less widely held, is that increasing particular matter in the atmosphere is blocking sunlight and lowering the earth’s temperature — a result that would be equally disastrous. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. Today we do not know for sure that either of these conditions will happen (though one recent government report drafted by experts in the field concluded that the greenhouse effect is very possible). Perhaps, if we are lucky enough, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now. Driven by economic profits, people neglect the damage on our environment caused by the “advanced civilization”. Maybe the air pollution is the price the human beings have to pay for their development. But is it really worthwhile?
小題1:As pointed out at the beginning of the passage, people used to think that air pollution _______.
A．cause widespread damage in the countryside
B．a(chǎn)ffected the entire eastern half of the United States
C．had damaged effect on health
D．existed merely in urban and industries areas
小題2:As to the greenhouse effect, the author __________.
A．share the same view with the scientist.
B．is uncertain of its occurrence
C．rejects it as being ungrounded
D．thinks that it will destroy the world soon
小題3:The word “offset” in the second paragraph could be replaced by _________.
A．slip into B．make up forC．set up D．catch up with
小題4:It can be concluded that ____________.
A．raising the world’s temperature only a few degrees would not do much harm to life on earth
B．lowering the world’s temperature merely a few degrees would lead major farming areas to disaster
C．a(chǎn)lmost no temperature variations have occurred over the past decade
D．the world’s temperature will remain constant in the years to come
小題5:This passage is primarily about __________.
A．the greenhouse effect　B．the burning of fossil fuels
C．the potential effect of air pollutionD．the likelihood of a new ice age

小題1:D
小題2:B
小題3:B
小題4:B
小題5:C

小題1:由第一段第一句話可推知。
小題2:第一段最后一句“If this view is correct ---”表明作者只是引用這種現(xiàn)象并不確定其正確性。
小題3:offset補償, make up for彌補, set up建立, catch up with趕上。
小題4:根據(jù)第二段第二句話“A drop of just a few degrees ---”可推知。
小題5:文章是在討論大氣污染給人類帶來的潛在影響。

Early one morning,more than a hundred years ago,an American inventor called Elias Howe finally fell asleep.He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired,Howe slept badly.He turned and turned.Then he had a dream.He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine.When he tried to do so,Howe ran into the same problem as before.The thread kept getting caught around the needle.The king flew into the cage and ordered his soldiers to kill Howe.They came up towards him with their spears raised.But suddenly the inventor noticed something.There was a hole in the tip of each spear.The inventor awoke from the dream,realizing that he had just found the answer to the problem.Instead of trying to get the thread to run around the needle,he should make it run through a small hole in the center of the needle.This was the simple idea that finally made Howe design and build the first really practical sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.Thomas Edison,the inventor of the electric light,said his best ideas came into him in dreams.So did the great physicist Albert Einstein.Charlotte Bronte also drew in her dreams in writing ?Jane Eyre.?
To know the value of dreams,you have to understand what happens when you are asleep.Even then,a part of your mind is still working.This unconscious(無意識的),but still active part understands your experiences and goes to work on the problems you have had during the day.It stores all sorts of information that you may have forgotten or never have really noticed.It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake.However,the unconscious part acts in a special way.It uses strange images which the conscious part may not understand at first.This is why dreams are sometimes called “secret messages to ourselves ”.
小題1:According to the passage,Elias Howe was_________.
A．the first person we know of who solved problems in his sleep
B．much more hard-working than other inventors
C．the first person to design a sewing machine that really worked
D．the only person at the time who knew the value of dreams
小題2:The problem Howe was trying to solve was_________.
A．what kind of thread to use
B．how to design a needle which would not break
C．where to put the needle
D．how to prevent the thread from getting caught around the needle
小題3:Thomas Edison is spoken of because_________.
A．he also tried to invent a sewing machine
B．he got some of his ideas from dreams
C．he was one of Howe's best friends
D．he also had difficulty in falling asleep
小題4:Dreams are sometimes called “secret messages to ourselves” because _________.
A．strange images are used to communicate ideas
B．images which have no meaning are used
C．we can never understand the real meaning
D．only specially trained people can understand them

A man who served 11 years in prison after being wrongly convicted of murdering his wife was officially cleared yesterday, walking free from Jingshan County People's Court—the same body that sentenced him to a 15?year jail term in 1998—as over 2000 local residents cheered.
“Police and other law enforcers made the errors,”39?year?old She Xianglin told China Daily, “I believe the law will punish them and give me a just result.”?
The original conviction came based on a confession which She said was extracted under police torture and the misidentification of a still-unknown woman's body.?
“The provincial Hubei government has sent a team of police, procurators and high people's court officials to investigate the case,” a spokesperson for the Jingmen government, which administrates Jingshan County, said yesterday.?
The miscarriage of justice only came to light when Shen's wife, Zhang Zaiyu, resurfaced late last month after being thought missing for 11 years.?
This was despite at least five letters from Zhang to her brother over the last two years, which he said he didn't report to police because he thought they were a hoax.?
Zhang disappeared in January 1994 from Yanmenkou Township, and 3 months later a body was found in a pond that her relatives positively identified.?
Local police arrested Shen for murder in April 1994,although questions had been raised about discrepancies between the features and clothes of the body and Zhang. Confirmation through DNA testing had not been attempted.?
　　Zhang Chengmao, Shen's lawyer, said yesterday he would seek State compensation “but we have not reached a figure yet”.?
When asked about compensation, Shen said, “My mother, who died from the stress of continually appealing, cannot be bought. Eleven years of freedom cannot be bought. Schooling of my daughter that was stopped because of poverty cannot be bought.”?
As for his wife, the man said he did not hate her at all. “If she had not reappeared, maybe I would have been wronged for life,” he said.?
He also said he did not plan to sue Zhang for bigamy, though she had remarried in Shandong Province without divorcing him.?
小題1:Why did She Xianglin served 11 years in prison?
A．Because She Xianglin was convicted of murdering his wife.?
B．Because the Police and other law enforcers made the errors.?
C．Because through DNA testing the dead woman was his wife.?
D．Because her wife was missing.
小題2:Which of the following is NOT true??
A．The miscarriage of justice only came to light when Shen's wife reappeared.?
B．The man said he did not hate her at all.?
C．Zhang Zaiyu wrote at least five letters to her brother over the last two years to hoax him.?
D．She Xianglin's mother died from the stress of continually appealing.
小題3:We can infer from the passage _______.?
A．She Xianglin will get State compensation?
B．She Xianglin's daughter dropped out of school because of poverty?
C．She Xianglin stayed in prison for 11 years?
D．who murdered the woman is known to all
小題4:The underlined word “cleared” in the first paragraph means _______.?
A．清除B．宣告無罪C．（天氣）變晴D．移走物體
