高三英语单项填空中等难度题查看答案及解析
In 2006, documents were published by the United States Food and Drug Administration (FDA). They suggested that cloned animals and cloned animal products would be allowed into the American food supply.
The FDA has stated that cloned animal products are safe for consumption, and has performed many studies to support this view. In fact, products from cloned animals have already been eaten by some Americans without ill effects. The FDA analyzed the structure(结构)and content of cloned animal products and compared it with that of traditionally reproduced animals, and discovered no statistical difference between the two.
Consumers raised serious concerns about cloned animals. The first is the question of whether or not cloned tissue and animal products are truly safe. The second is that many clones are also genetically modified(转基因的)animals, which the FDA has said are unsafe for human consumption. The third is that consumers want to be able to choose what they put into their bodies.
The first concern about cloned animals is almost unnecessary due to the price of producing a clone. Making a clone needs hard work and is very costly. These clones live spoiled lives because they are very valuable, despite biologists' warning that cloned animals decrease diversity.
The second concern, about genetic modification of cloned animals, is more problematic. It may be very difficult to separate genetically modified animals from normal ones. The purpose of genetically modified cloned animals is unclear, and the FDA hasn't allowed their products onto the market, due to health concerns, but the risk of genetic pollution of healthy animals still exists.
Finally, the matter of choice is a large one. Many animal rights activists are worried about clone rights because cloned or not, the animals still have lives. Other consumers are simply trying to eat healthy foods, and have doubts about the cloned animals. If the FDA does not make labeling (贴标签)laws, people may not be able to make informed choices about their food.
1.Why did the FDA allow cloned animal products for consumption?
A.They appeal to consumers very much.
B.They differ from traditional animal products.
C.They taste better than normal animal products.
D.They have been proved safe in several aspects.
2.What do we know about producing clones of animals?
A.It takes much more efforts and money. B.It provides some new medical benefits.
C.It needs less time than raising animals. D.It helps increase the diversity of animals.
3.What can be inferred from the last paragraph?
A.Cloned animals should be forbidden to enter market.
B.Cloned animals should have the same rights as humans.
C.Laws should be made to protect people's right to choose food.
D.Animal rights activists are strongly against cloned animal products.
4.What's the text mainly about?
A.Doubts about cloned animals rights. B.Discussions about how to clone animals.
C.Concerns about animal cloning technology. D.Worries about cloned animal consumption.

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 field（电磁场） 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.
Roosegaarde 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.
1.The device works by _______.
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
2.According to the passage, ______ .
A. the Beijing government has agreed to use the technology in Beijing
B. they have proven the results of the device both indoors and outdoors
C. the results of the air-cleaning device can be expectable
D. the Beijing government has never done anything to handle the air pollution
3.What does Roosegaarde really mean by saying “Beijing is quite a good place…... ”?
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.
4.Roosegaarde appeals to people in Beijing to ________.
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
