【题目】A Brown University sleep researcher has some advice for people who run high schools: Don't start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to make sure bedtime. Instead, it may be that biologically these sleepyhead students aren't used to the early hour. "Maybe these kids are being asked to get up at the wrong time for their bodies, " says Mary Carskadon, a professor looking at problems of adolescent sleep at Brown's School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And , at a more basic level, she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns. Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought. Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at night and sleep later in the morning. But it's not just a matter of choice—their bodies are going through a change of sleep patterns.
All of this makes the change from middle school to high school—which may start one hour earlier in the morning—all the more difficult, Carskadon says. With their increased need for sleep and their biological clocks set on the "sleep late, rise late" pattern, adolescents are up against difficulties when it comes to trying to be up by 5 or 6 a. m. for a 7: 30 a. m. first bell. A short sleep on a desktop may be their bodies' way of saying, "I need a timeout. "
【1】Carskadon suggests that high schools should not start classes so early in the morning because ________.
A. it is really tough for parents to ensure bedtime
B. students are so lazy that they don't like to go to school early
C. students work so late at night that they can't get up early
D. it is biologically difficult for students to rise early
【2】The underlined phrase "nod off"(Paragraph l) most probably means "________".
A. turn around B. agree with others
C. fall asleep D. refuse to work
【3】What might be a reason for the hard change from middle school to high school?
A. Adolescents depend more on their parents.
B. Adolescents need more sleep than they used to.
C. Adolescents sleep better than they did at childhood.
D. Adolescents have to choose their sleep patterns.
【4】What is the text mainly about?
A. Changes in adolescent sleep needs and patterns.
B. Problems in adolescent learning.
C. Adolescent sleep difficulties.
D. Adolescent heath care.
【答案】
【1】D
【2】C
【3】B
【4】A
【解析】研究表明,由于生理原因和生活模式的改变,由初中到高中,青少年们需要更多的睡眠,早起更困难,所以学生们不应该早上上课太早。
【1】D细节推理题。根据第一段Instead, it may be that biologically these sleepyhead students aren't used to the early hour.可知,Carskadon认为学生们不应该早上上课太早,原因是这些上课打瞌睡的学生生理上不适应早起,故选D。
【2】C猜测词义题。句意:并不是在课桌上打盹的学生懒惰。nod off “打盹” 与C项同义,故选C。
【3】B推理判断题。根据第二段Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.和最后一段All of this makes the change from middle school to high school—which may start one hour earlier in the morning-all the more difficult,及With their increased need for sleep and their biological clocks set on the "sleep late , rise late" pattern, adolescents are up against difficulties几处可知,由初中到高中,青少年们需要更多的睡眠,早起更困难。故选B。
【4】A主旨大意题。本文讲述了研究表明,由于生理原因和生活模式的改变,由初中到高中,青少年们需要更多的睡眠,早起更困难,所以学生们不应该早上上课太早。故选A。

【题目】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(复制的) 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

【题目】Most drinks stating that they are fruitflavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be nonexistent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. __【1】__ It will increase profits, and consumers won't always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberryflavored products sold in stores. __【2】__ Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
__【3】__ Let's take jam as an example. Some strawberryflavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
__【4】__ Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. __【5】__ Unfortunately, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”
A. The products which contain real fruit are popular with people.
B. Even products advertised as more natural often contained no fruit.
C. They found that about 60 percent of them didn't contain any fruit at all.
D. If companies can cut their costs by using flavoring, they are likely to do so.
E. It is important and necessary to demand a small amount of flavoring in the products.
F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.
