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.
1.What difficulties might early European settlers meet in America EXCEPT ______?
A. the fierce conflict with Native Americans
B. bad-tempered natives who enjoyed killing
C. unfamiliarity with a foreign land
D. lack of food in winter
2.Pocahontas saved John Smith twice because ______.
A. he was the first white man she had ever seen in her life
B. she wanted to become a Christian and marry an Englishman
C. she believed in general kindness even to people of a different race
D. she was on the settlers’ side and against her cruel father
3.Which is NOT an element to make Pocahontas a legend?
A. Her tribal background and her marriage to a white settler.
B. Her selfless help to people regarded as enemy of her tribe.
C. Her complicated life story different from common people’s.
D. The recreation of her life story in the 1995 Disney film.
4.According to the text, Europeans think Pocahontas _____.
A. was brave to break away from her own tribe
B. set a good example for other natives to accept the white settlers
C. was a selfless Christian who can love her enemy
D. was open to a more advanced culture
5.What can we infer from the passage?
A. The battles between early settlers and Native Americans resulted from their fighting for land.
B. The Europeans think the early settlers should have learned to adjust to the local cultures.
C. The creation of America is based on the settlers’ victory over the Native Americans.
D. People from different cultures can never really get along well with each other.
B
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.

Identifying young people with the potential to be great athletes has become a serious, business around the world. Many countries, including Australia, have sophisticated(复杂) programs for identifying and nurturing(培养) talent.
The AIS (Australian Institute of Sport) already runs a program that identifies potential winners starting from the age of 12 based on their physical and physiological(生理的) abilities.
Could genetics improve these programs? The problem is that no one gene test is ever going to do an accurate job of identifying someone with the physical attributes of a sporting champion, says Professor North.
"We can think of the elite athlete as what I'd call a complex phenotype(表现型)," she says. “There are going to be a large number of different genes involved. Any one single test is unlikely to be highly predictive.”
Professor Peter Fricker, director of the AIS, agrees. Although he is intrigued in the possibilities of genetic testing, he says using such tests to identify athletes would be difficult. "The feeling I have is that it won't be that easy," he says. "Talent selection is not just about your genes."
Since 2004, the AIS has been forbidden by government from any involvement in genetic work, including genetic testing. But Professor Fricker thinks that is likely to change in the near future. "There's been a shift in view more recently," he says.
When it does, the AIS will resume its work on the genetics of sports performance, Professor Fricker says. They would be particularly interested in looking for more genes that might help shape elite performance, but also for genes that increase the risk of injury.
Last year, the Human Genetics Society of Australasia issued a position statement on gene testing for sport, after concerns that people could use tests to steer children into particular sports.
“The Human Genetics Society thinks there are not enough data to use these tests for determining what sport kids should do,” said Professor David Thorburn, president of the society.
He stressed that genetic tests should not be performed on children, except in very specific medical circumstances.
57．The aim of the AIS’s program is to .
A．predict how genes are connected with injuries
B．find potential great athletes
C．find out what qualities a professor has through gene tests
D．turn an athlete into a champion by transferring genes
58．By saying “Talent selection is not just about your genes”, Fricker means .
A．effort is more important than genes in most cases
B．you can’t choose an athlete just depending on genes
C．to research one’s genes takes a long time
D．most people don’t believe in genetic tests
59．The underlined word “resume” in Para. 7 can be replaced by .
A．stop B．complete C．reduce D．continue.
60．What’s Professor David Thorburn’s attitude towards genetic tests?
A．Genetic tests have a negative effect on children.
B．Genetic tests, under certain conditions, can be conducted on children.
C．Genetic tests can reduce the risk of athletes’ injuries.
D．People could use genetic tests to decide what sport kids should take.

Even if we have an extremely healthy diet and lifestyle, the human body is programmed to wear out at a maximum of about 120 years, and usually less. We all have a biological clock inside us which determines the moment when our organs cease to function properly. This is because our cells have stopped renewing themselves and our body can no longer repair itself. This is also the moment when we are more likely to begin to suffer from the diseases of old age such as arthritis and Alzheimer’s. However, rapid advances in DNA research are beginning to throw light on the secrets of the ageing process. By the end of this century we could literally have the power of life over death.
Although it has long been accepted that humans have a fixed lifespan, it is also a fact that certain other organisms, such as reptiles and amphibians, appear to live indefinitely. The only reason we do not see 500-year-old alligators is because in the wild their lives are always in danger, from man, from pollution and from other animals. When they are kept in zoos they do not seem to age at all after they are fully grown. The same is true of some species of fish, which grow indefinitely and show no signs of ageing. The existence of animals with no fixed lifespan seems to indicate that an age gene really does exist. It is this gene which scientists are searching for, which may delay or repair damage to the body caused by ageing.
Another new area of research involves the oxidation（氧化） theory, which says that ageing is caused by the same process that makes iron rust. In controlled experiments, the lifespans of certain animals were shown to be lengthened with anti-oxidants; for example, the lifespan of mice can be increased by 30%. Antioxidants are already being used in face creams and other cosmetics, and they are likely to play an important part in keeping people physically young.
Perhaps the most immediate advance we are likely to see in the battle to halt（停止）the ageing process will be organ replacement. By the year 2020 it is likely that we will be replacing injured bones or even organs like livers and kidneys with ones “grown” in laboratories. By 2050 perhaps every organ in the body, except the brain, will have become commercially available. Recent experiments also show that it may one day be possible to “grow” new organs inside our body to replace worn-out ones, something which lizards and alligators already do.
Suddenly immortality（不死，不朽） seems within reach. We can begin to imagine a future where we are born, we grow to maturity, but we never grow old and die. But do we really want to live forever?
【小题1】 When all humans reach a certain age, .
| A．they suffer the effects of their diet and lifestyle |
| B．the organs stop to perform appropriately |
| C．their cells continue to renew themselves |
| D．they develop arthritis and Alzheimer’s |
| A．alligators are in danger in the wild because of the threat from man, pollution and other animals |
| B．it is widely accepted that humans have a fixed lifespan |
| C．there exists an age gene which may control ageing |
| D．the age gene damages the body |
| A．live for a period of time without a fixed end |
| B．live without a clear aim |
| C．live in an uncertain way |
| D．live without being fully grown |
| A．by 2050 we might have most of our worn-out organs replaced with new ones commercially |
| B．never can the ageing process be avoided |
| C．livers and kidneys are sure to be grown in laboratories by the year 2020 |
| D．lizards and alligators grow new organs inside their body to replace worn-out ones |
| A．DNA researches show how our cells renew themselves. |
| B．Anti-oxidants are likely to play an important part in keeping people young. |
| C．How our biological clock works? |
| D．Eternal（永恒的） youth: new developments in anti-ageing research. |
| A．a future where we are born, we grow to maturity, but we never grow old and die is on its way |
| B．he is uncertain whether we can live forever |
| C．it remains to be seen whether immortality is a blessing or a curse |
| D．immortality is no longer a dream |
