Research suggests that a newly-identified gene known as insomniacs(失眠症患者) may play a role in keeping us asleep. By cloning and testing this gene in about 21,000 fruit flies, Rockefeller University researchers say they have discovered an entirely new mechanism (机制) by which sleep is controlled.
By studying these flies, the researchers discovered that mutations(变异) in the insomniac gene were associated with a great reduction in sleep. While a typical fruit fly slept for an average of 927 minutes a day, the mutant flies slept for just 317. They also slept for shorter periods of time, and slept and woke more frequently.
“The results showed a great loss of both the time that the flies’ sleep lasted and their ability to remain asleep after they slept,” says researcher Nicholas Stavropoulos.
The researchers also examined the link between sleep and lifespan, finding that flies with mutations to the insomniac gene lived only about two-thirds as long as unchanged flies. But when the scientists removed insomniac only in neurons(神经细胞)---allowing it to remain in the rest of the flies’ bodies---this difference disappeared; the resulting animals slept poorly but lived just as long.
“This suggests that reduced sleep can be ‘uncoupled’(分开) from reduced lifespan, supporting the idea that some interruptions of sleep do not affect overall health, at least as far as lifespan is concerned,” Stavropoulos says.
Although flies and humans would appear to have little in common when it comes to lifestyle, scientists say that the mechanisms of sleep and wakefulness are likely to be quite similar.
“Sleep is a fundamental behavior in all animals, and it is poorly understood from a scientific standpoint, says Stavropoulos. This work could prove useful in understanding and treating sleep disorders”

It’s been claimed that playing a musical instrument makes you smarter.
New research suggests that regularly playing a musical instrument changes the shape and power of the brain, and may be used in therapy (疗法) to improve cognitive (认知) skills.
Experts say there is growing evidence that musicians have brains that are structurally and functionally different from those of non-musicians, especially in the areas of the brain used in processing (处理信息)
The parts of the brain that control motor skills, the storage of audio information, hearing and memory become larger and more active when a person learns how to play an instrument and can apparently improve the alertness (警觉) and planning.
Lutz Jancke, a psychologist at the University of Zurich, said, “Leaning to play a musical instrument has great benefits and can increase IQ by seven points in both children and adults.We found that even people over the age of 65, after four or five months of playing an instrument for an hour a week, had strong changes in the brain.” The parts of the brain that control hearing and memory, and the part that controls the hands, among others, all become more active.
“Of course music isn’t the only answer, but I do believe that it should be used in addition to other things.”
Mr.Jancke also said that learning a musical instrument could also make it easier to learn foreign languages and make one more sensitive to understanding the emotions of others.“So not only does this make it easier to pick up other languages and have a better memory of one’s own, we have also seen musicians are able to pick out exactly what others are feeling just by the tones of their voices—sympathy, disappointment, that kind of things.”
He added, “Several studies indeed show that playing music increases memory and language skills, but more research is needed.”
1.What is the passage mainly about?
A.How to use musical instruments.
B.How music affects the brain.
C.How playing music makes people smarter.
D.The development of research into music.
2.Compared with non-musicians, __________.
A.musicians are better at foreign languages
B.musicians are more active in sports
C.musicians have stronger emotions
D.musicians’ brains work differently in processing
3.Which of the following is NOT a benefit of playing an instrument?
A.It makes it easier for one to pick up foreign languages.
B.It allows one to show his feelings more exactly to others.
C.It gives one a better memory in one’s own language.
D.it makes one understand others’ feelings better.
4.From Luz Jancke we lean that _________.
A.playing an instrument benefits children more than adults
B.playing an instrument has no benefits for people over 65
C.some studies show playing music can increase memory
D.he will do more research into brain development and music

In the 19th century, an Arab physician known as Zuhr Ibn conducted some animal research to assess the surgical procedures that could be applicable in humans. Since then, animal testing has been considered to be the most efficient way to develop new drugs. New medical treatments and drugs are tested in animals first to determine their effectiveness or safety levels before they are finally tested on humans. However, it remains controversial whether it is morally right or wrong to use animals for medical or commercial experiments.
Use of animals for medical purposes is seen to be necessary by many scientists. Researchers usually begin their trials using rats. If the tests are successful, further tests are done on monkeys before using human beings. For testing, such tiered(分层的) rounds are important because it reduces the level of error and any negative side effects. Some argue that animal testing has contributed to many life-saving cures and treatments and there is no adequate alternative to testing on a living, whole-body system. Moreover, there are regulations for animal testing that limit the misuse of animals during research, which serves as evidence that animals are well taken care of and treated well instead of being intentionally harmed.
However, some other experts and animal welfare groups have opposed such practice, terming it as inhumane(不人道的) and claiming it should be banned. According to Humane Society International, animals used in experiments are commonly subjected to force feeding, radiation exposure, operations to deliberately cause damage and frightening situations to create depression and anxiety. They also hold the view that animals are very different from human beings and therefore make poor test subjects. Drugs that pass animal tests are not necessarily safe. Animal tests on the arthritis(关节炎) drug Vioxx showed that it would have a protective effect on the hearts of mice, yet the drug went on to cause more than 27,000 heart attacks before being pulled from the market.
It’s safe to say that using animals for tests will continue to be debated in many years to come. Despite the benefits of animal testing, some of the animal welfare organizations’ concerns need to be addressed with adequate regulations to ensure that animals are treated humanely.
1.Why is animal testing considered necessary?
A.Because rats are more similar to humans than monkeys.
B.Because other testing alternatives may not replace the need for animals.
C.Because animal testing can spare humans any side effect.
D.Because animal testing has been in practice since the 19th century.
2.What suffering do animals go through during experiments?
A.Eating poisonous food.
B.Being killed deliberately.
C.Breathing in polluted air.
D.Having unnecessary operations.
3.What does the example Vioxx in paragraph 3 tell us?
A.Arthritis is hard to cure.
B.Some drugs need to be withdrawn from the market.
C.Animals can not necessarily produce accurate results.
D.A drug should be tested many more times before its release.
4.What action will the author probably agree with?
A.Experts try hard to determine whether animal tests are harmful.
B.The authorities issue a new law to guarantee animal rights during research.
C.Scientists reduce the number of animals used in research.
D.Relevant organizations show more concern about the animals’ welfare.

The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q., a generally bad predictor of success. Instead, it’s purposeful practice. Top performers spend more hours practising their craft. It you wanted to picture how a typical genius might develop, you’d take a girl who possessed a slightly above average language ability. It wouldn’t have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.
This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating circle who might someday join. It would also help if one of her parents died when she was 12, giving her a strong sense of insecurity and fueling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She’s be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, she delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback, viewing her performance form the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems — how do I get characters into a room—dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It’s the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we’re “hard-wired” to do. And it’s true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.
1.The passage mainly deals with .
A. the function of I.Q. in cultivating a writer
B. the relationship between genius and success
C. the decisive factor in making a genius
D. the way of gaining some sense of distinction
2.By reading novels and writers’ stories, the girl could .

A new Japanese research has suggested that regularly eating mushrooms could help lower the risk of cancer. The researchers found that the men who consumed mushrooms once or twice a week had an 8 percent lower risk of developing cancer, regardless of how much fruit and vegetables, or meat and dairy products they ate—compared to those who ate mushrooms less than once per week. Eating mushrooms more often appeared to bring even bigger benefits, with those who consumed mushrooms three or more times per week showing a 17 percent lower risk than those who ate mushrooms less than once a week.
Eating mushrooms also appeared to be particularly beneficial among those who ate a large amount of meat and dairy products, little fruit and few vegetables. The findings, published in the International Journal of Cancer, are the first to suggest that there may be an association between eating mushrooms and a lower risk of cancer.
“Test-tube studies and studies conducted on living organisms have shown that mushrooms have the potential to prevent cancer” said lead researcher Shu Zhang. “To the best of our knowledge, this is the first study indicating the cancer-preventive potential of mushrooms at a population level.” Zhang added that, “mushrooms are a good source of vitamins, minerals and antioxidants, especially L-ergothioneine,” which is believed to help fight against stress, and that is cell imbalance caused by lifestyle choices such as poor diets and exposure to environmental poisons. This imbalance can lead to chronic inflammation, resulting in chronic diseases such as cancer.
“Considering the average American consumes less than 5 grams of mushrooms per day, which is lower than that consumed by the participants in this study (7.6 g/day), one would expect that even a small increase in mushroom consumption can offer potential health benefits,” said Zhang. However, Zhang added that, “Although our study suggests regular consumption of mushrooms may reduce the risk of cancer, we also want to emphasize that eating a healthy and balanced diet is much more important than filling your shopping basket with mushrooms.”
1.What is the new Japanese research about?
A.Healthy lifestyle reduces the risk of cancer.
B.Often eating mushrooms reduces the risk of cancer.
C.Drinking dairy products is good for our health.
D.Eating fruit and vegetables makes us healthier.
2.Who seem to especially benefit from eating mushrooms?
A.People who are over fat and having a poor diet.
B.People who are feeling over stressed.
C.People who consume much meat but few vegetables and little fruit.
D.People who consume many dairy products and suffer cancer.
3.Why can the mushroom help reduce the risk of cancer?
A.It avoids the stress from a disease.
B.It reduces environmental poisons.
C.It hell helps reduce weight.
D.It has a source of cancer-preventive.
4.What does the underlined word “inflammation” probably means?
A.A state of being physically healthy.
B.A state of keeping body balance.
C.A physical condition that someone needs to be on a diet.
D.A condition that a part of the body becomes red, sore and swollen.
