Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes (糖尿病) patients who were given a good dose of humor for a year to prove it.
Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments.
By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine (肾上腺素), considered to cause stress, which is known to be deadly.After the 12 months, HDL cholesterol rises 26 percent in Group L but only 3 percent in Group C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group.
“The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter,” said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy.
“Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment,” Berk said in a statement this week.
1.Why did the scientists carry on the new research?
A.To find out if laughter was good to health.
B.To discover the best medicine to cure diabetes.
C.Because the number of diabetic patients is the largest in the world.
D.Because diabetic patients need more laughter than other patients.
2.After 12 months into the study, ___________.
A.C-reactive proteins increase 66 percent in Group C
B.the level of the hormones epinephrine stays the same in both groups
C.the level of the hormones epinephrine has dropped
D.C-reactive proteins reduced 66 percent in Group L
3.The underlined part “HDL cholesterol” in Paragraph 3 must be _______.
A.something bad to our health B.something good to our health
C.a kind of wonderful medicine D.a kind of dangerous disease
4.In what way does laughter benefit people’s health?
A.Blood is made thick by laughter.
B.Laughter makes blood vessels thin.

高三英语七选五简单题查看答案及解析
There is an English saying : “ Laughter is the best medicine.” Until recently, few people took the saying very seriously. Now however, doctors have begun to study laughter and the effects it has on the human body. They have found facts that laughter really can improve people’s health.[
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reducing the effect of pain on the body. In one experiment doctors produce pain on the body. In one experiment doctors produce pain in groups of students who listened to different radio programs. The group which tolerated(忍受) the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins in the brain. These are natural chemicals which diminish both stress and pain.
There is also some fact to suggest that laughter helps the body’s immune system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group of students served as the control group ---- in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watch the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists in the United States now hold laughter clinics, in which they try to improve their patients’ condition by encouraging them to laugh.
They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.
1.It can be learnt from the passage that laughter can_______.
A. make people feel younger
B. change people’s habits
C. improve peoples health
D. make people love their lives
2.Smiling can produce____.
A. more effects than laughter
B. the same effects as laughter
C. less effects on the human body
D. no effects on the human body
3.The main idea of this passage is that ______.
A. there are several ways of studying the benefits of laughter
B. laughter and physical exercise have the same effects on human body
C. the doctors should learn how to make people laugh
D. tests show that laughter can produce beneficial effects on human body

The world is not only hungry, but it is also thirsty for water.This may seem strange to you,since nearly 70 percent of the earth's surface is covered with water.But about 97 percent of this huge amount is sea water, or salt water.Man can only drink and use the other 3 percent-the fresh water from rivers,lakes,underground,and other sources.And we cannot even use all of that,because some of it is in the form of icebergs and glacier.Even worse,some of it has been polluted.
However,as things stand today, this small amount of fresh water is still enough for us.But our need for water is increasing rapidly-almost day by day.Only if we take steps to deal with this problem now can we avoid a severe worldwide water shortage later on.
We all have to learn how to stop wasting our valuable water.One of the first steps is to develop ways of reusing it.
Today in most large cities,water is used only once and then sent out into a sewer system.From there it returns to the sea or runs into underground storage tanks.But it is possible to pipe used water to a purifying plant.There it can be treated with chemicals so that it can be used again,just as if it were fresh from a spring.
But even if every large city purified and reused its water,we still would not have enough.All we'd have to do make use of the vast reserves of sea water in the world is to remove the salt.
If we take these steps we'll be in no danger of drying up.
1.The world is thirsty for water because we can only use________ percent of the water covering the surface of the earth.
A.3 B.more than 3 C.less than 3 D.97
2.Which of the following statements is NOT TRUE?
A.As things remain unchanging,this small amount of fresh water is still enough for us.
B.Our need for water is becoming larger and larger.
C.There will be no water shortage in the future.
D.We should take steps to deal with the water shortage problem.
3.To reuse water, we should ________.
A.treat it with chemicals B.use it only once
C.send it out into a sewer system D.make it flow into underground tanks
4.In order to have enough water.we should also make use of________.
A.icebergs and glaciers B.sea water
C.rivers and lakes D.underground water

高三英语阅读理解简单题查看答案及解析
Helping yourself to a cup of coffee may seem like a small, everyday thing. But it is not the case if you are quadriplegic (四肢瘫痪). Quadriplegics have lost the use of all four limbs. Thanks to a project organized by John Donoghue of Brown University, in Rhode Island, and his colleagues, quadriplegics have hope.
One of the participants in his experiments, a 58-year-old woman who is paralyzed and unable to use any of her limbs, can now pick up a bottle containing coffee and bring it close enough to her mouth to drink from it using a straw. She does so using a thought-controlled robotic arm fixed to a nearby stand. It is the first time she has managed something like that since she suffered a stroke, nearly 15 years ago.
Arms are more complicated pieces of machinery than legs, so controlling them via electrodes (多波段电极) attached to the skin of someone’s scalp (头皮) is not yet possible. Instead, brain activity has to be recorded directly. And that is what Dr Donoghue is doing. Dr Donoghue and his team have had small, multichannel electrodes implanted in the parts of the motor cortexes (运动皮质) of participants’ brains associated with hand movements.
Dr Donoghue and his team decoded signals from their participants’ brains as they were asked to imagine controlling a robotic arm making present movements. The woman and other volunteers were then encouraged to operate one of two robot arms by thinking about the movements they wanted to happen. When the software controlling the arms detected the relevant signals, the arms moved appropriately. The arm that the woman used to help herself to a drink is a lightweight device developed by DLR, German’s Aerospace Centre, as part of its robotics program.
Dr Donoghue and his colleagues have thus shown that a mechanical arm can be controlled remotely by the brain of a person with paralysis. Controlling an arm that is attached to the individual’s body will be trickier, but in time even that may be possible. In the meantime, a robotic arm attached to a wheelchair will be a real soon.
1.What does the underlined word “that” in Paragraph3 refer to?
A.Controlling a robotic arm via electrodes attached to the scalp.
B.Recording the activity of brain and implanting electrodes.
C.Controlling a robotic leg via electrodes attached to the scalp.
D.Controlling a mechanical arm attached to the individual’s body.
2.Which statement may the author agree with?
A.Thanks to the research by Dr Donoghue and his colleagues, a paralyzed woman can get herself a drink.
B.The woman in the experiment drinks a bottle of coffee with a robotic arm attached to her scalp.
C.The woman is encouraged to control the mechanical arm by moving her body.
D.The robotic arm the woman used is remoted by DLR.
3.What’s the author’s attitude to the future of the robotic arm attached to quadriplegic?
A.Pessimistic. B.Objective.
C.Controversial. D.Optimistic.
4.What’s the main idea of the text?
A.Quadriplegics can use the artificial limbs developed by Dr Donoghue and lead a good life by themselves.
B.The newly-developed thought-controlled robotic arms can help the paralyzed in their daily life.
C.Scientists have invented a kind of robotic arm attached to the individual’s body.
D.A quadriplegic can be on his feet again due to the new invention.

The Best of Friends
The evidence for harmony may not be obvious in some families.But it seems that four out of five young people now get on with their parents,which is the opposite of the popularly-held image(形象) of unhappy teenagers locked in their room after endless family quarrels.
An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past.“We were surprised by just how positive today’s young people seem to be about their families,”said one member of the research team.“They’re expected to be rebellious(叛逆的) and selfish but actually they have other things on their minds:they want a car and material goods,and they worry about whether school is serving them well.There’s more negotiation(商议) and discussion between parents and children,and children expect to take part in the family decision-making process.They don’t want to rock the boat.”
So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends.“My parents are happy to discuss things with me and willing to listen to me,”says 17-year-old Daniel Lazall.“I always tell them when I’m going out clubbing.As long as they know what I’m doing,they’re fine with it.”Susan Crome,who is now 21,agrees.“Looking back on the last 10 years,there was a lot of what you could call negotiation.For example,as long as I’d done all my homework,I could go out on a Saturday night.But I think my grandparents were a lot stricter with my parents than that.”
Maybe this positive view of family life should not be unexpected.It is possible that the idea of teenage rebellion is not rooted in real facts.A researcher comments,“Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings.But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled.The normal situation throughout history has been a smooth change from helping out with the family business to taking it over.”
1.What is the popular image of teenagers today?
A.They worry about school.
B.They dislike living with their parents.
C.They have to be locked in to avoid troubles.
D.They quarrel a lot with other family members.
2.The study shows that teenagers don’t want to _______.
A.share family responsibility
B.cause trouble in their families
C.go boating with their family
D.make family decisions
3.Compared with parents of 30 years ago,today’s parents _______.
A.go to clubs more often with their children
B.are much stricter with their children
C.care less about their children’s life
D.give their children more freedom
4.According to the author,teenage rebellion _______.
A.may be a false belief
B.is common nowadays
C.existed only in the 1960s
D.resulted from changes in families
5.What is the passage mainly about?
A.Negotiation in family. B.Education in family.
C.Harmony in family. D.Teenage trouble in family.
