阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项。

A

Imagine landing in a foreign country where you cannot speak the language, understand the culture and don’t know anybody. Wouldn’t it be nice to have a friend who could help you out?

John Smith, an English explorer who landed in America in 1607, found the best friend ever. She was a Native American named Pocahontas (1595-1617). And she did more than teach Smith the language: she saved his life, twice.

Smith was captured by members of Pocahontas’s tribe (部落) and was going to be killed. But for some reason, the Chief’s daughter, Pocahontas, felt sorry for Smith (who was probably the first white man she had ever seen) and threw her body over his to protect him. Smith returned safely to the small village he was living in.

During the winter the English settlers did not know how to get food from nature. Pocahontas often brought food for Smith and his friends.

A year later Pocahontas’s father tried to kill Smith again because the Native Americans were very scared the English would try to take over their land. Pocahontas warned him and he was able to escape.

Later she became a Christian and eventually married an Englishman named John Rolfe.

She spent the last year of her life in London.

Pocahontas has become an American legend (传奇). Her life story has been re-created in many books and films, including Disney’s 1995 film, Pocahontas.

One of the reasons she is so popular is that many Europeans look at Pocahontas as an excellent example of how a minority can adjust into the majority. Pocahontas is also respected because of her selfless love. She proved that people can be kind and loving even to people of a different race or culture. John Smith was very different from Pocahontas but she could see he was a good man and that was all that mattered. No race or country owns goodness, love and loyalty.

Chinese students aren’t the only ones who have a sleep loss problem. In Australia, teenagers are also missing out on, on average, one hour’s sleep every night during the school week.

Organized activities and homework push bedtimes later, the first large-scale Australian study of children’s sleeping habits has revealed (显示). Their sleep deprivation (剥夺) is enough to cause “serious drop-offs in school performance, attention and memory”, and governments should consider later or flexible school start times, said the study’s leader, Tim Olds.

 His survey, of more than 4,000 children aged 9 to 18, found those who slept least did not watch more television but spent their time socializing (相处) with family or friends or listening to music.

“Almost all children get up at 7 or 7:15 — they have to get to school on time,” said Olds. He favors a later start over an earlier finish because he believes organized sports and activities would still consume the latter end of the day.

Olds’research also establishes lack of sleep as a cause of weight gain in children, and a possible source of future problems with depression, anxiety and increased susceptibility (易感性) to illness.

It was already known that overweight children sleep less, but Professor Olds found sleep duration (时长) was strongly linked to weight across the full range of body sizes. The thinnest children sleep 20 minutes more than the obese. This showed being overweight had no specific effect on sleep patterns, and it was more likely that shorter sleep times stimulate (刺激) appetite and make kids hungry.

The US National Sleep Foundation says teenagers aged 13 to 18 need eight to nine hours’ sleep a night. Younger school-aged kids need 9 to 11 hours.

On that basis, Professor Olds said, half of Australian children are under-sleeping on weekdays and a quarter on weekends.

6. The Australian students surveyed don’t sleep enough because they spend more time on the following EXCEPT _____.

A. organized activities and homework

B. communication with friends and family

C. watching television programs

D. enjoying music 

7. What effects does lack of sleep directly have on the students according to the survey?

A. They become overweight but begin to eat less than before.

B. They feel more depressed and anxious about their school work.

C. They are more likely to be affected with illness in the future.

D. They pay less attention in class and their memory declines.

8. Which of the following suggestions did Mr. Olds raise?

A. The students should go to bed earlier to have longer sleeping time.

B. The students should participate less in organized activities.

C. The school should put off the start time in the morning.

D. The school should finish earlier in the afternoon.

9. What does "obese" in the sixth paragraph mean?

A. average      B. fat     C. sleepless   D. overeating

10. Which of the following statements is TRUE?

A. Australian students usually take part in activities in the afternoon.

B. More students are short of sleep on weekends than on weekdays.

C. Being overweight has an effect on the length of the sleeping time.

D. The survey suggests that teenagers need 8-9 hours’ sleep a night.

C

By day he is just a normal cat but when the lights go out, he glows (发光) in the dark.

Scientists have genetically modified (更改) a cat as part of an experiment that could lead to treatments for diseases.

Named Mr. Green Genes, he looks like a six-month-old cat but, under ultraviolet (紫外线的) light, his eyes, gums (牙龈) and tongue glow green. That is the result of a genetic experiment at the Audubon Center for Research of Endangered Species in New Orleans, US.

Mr. Green Genes is the first fluorescent (荧光的) cat in the US and probably the world, said Betsy Dresser, the center's director.

The researchers made him so they could learn whether a gene could be introduced harmlessly into a cat's genetic sequence (次序).

If so, it would be the first step in a process that could lead to the development of ways to treat diseases via gene therapy (治疗).

The gene, which was added to Mr. Green Genes' DNA, has no effect on his health, Ms Dresser said.

Cats are ideal for this project because their genetic makeup is similar to that of humans, said Dr Martha Gomez, a scientist at the center.

To show that the gene went where it was supposed to go, the researchers settled on one that would glow.

The gene "is just a marker"，said Leslie Lyons, an assistant professor at the University of California, Davis. Lyons is familiar with the center's work.

 "The glowing part is the fun part," she said.

 Glowing creatures made international news earlier this month when the Nobel Prize in Chemistry was awarded to three scientists who had discovered the gene through their work with jellyfish (水母).

11.Which of the following might be the best title for the passage?

A. A Glowing Cat                  B. Mr. Green Genes

C. One Cat’s Life                  D. An experiment on cats

12. What can we conclude from the passage?

A. Fortunately, scientists have found ways to treat diseases via gene therapy.

B. Scientists think cats’ genetic makeup is the same as that of human beings.

C. Three scientists who had discovered the gene were given Nobel Prize in  Physics.

D. Scientists have managed to introduce a gene into a cat’s genetic sequence.               

13. What does “settled on” most probably mean in Paragraph 9?

A. chose         B. killed        C. took          D. raised

14. From the passage we can see that ____.

A. Mr. Green Genes was made by researchers to treat diseases

B. the cat named Mr. Green Genes can glow when it is dark

C. Mr. Green Genes is the first fluorescent cat in the world

D. Mr. Green Genes is a cat of seven months old up to now

15. Which of the following is WRONG according to the text?

A. The gene added to Mr. Green Genes’ DNA doesn’t affect its health at all.

B. The scientists came up with the idea of the glowing genes totally for fun.

C. Earlier this month glowing creatures became news all through the world.

D. Scientists had discovered the gene from the jellyfish they worked with.

　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."

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.

What is the main idea of para4?

A. A study claimed to be the first large-scale look at Internet overuse.

B. The American Psychiatric Association plans to list Internet addiction in its edition.

C. There are heated discussions about negative experiences over internet overuse.

D. There is a growing concern towards internet addiction.

According to Professor Maressa Orzack, Internet use would be considered excessive if ______.

　A. it seriously affected family relationships

　B. one visited porn websites frequently

　C. too much time was spent in chat rooms

　D. people got involved in online gambling

According to Orzack, people who struggle with heavy dependence on
