内容:
Researchers have established that when people are mentally engaged,biochemical changes occur in the brain that allow it to act more effectively in cognitive(认知的) areas such as attention and memory.This is true regardless of age.People will be alert(警觉的) and receptive (愿意接受的) if they are faced with information that gets them to think about things they are interested in.And someone with a history of doing more rather than less will go into old age more cognitively sound than someone who has not had an active mind.Many experts are so convinced of the benefits of challenging the brain that they are putting the theory to work in their own lives.“ The idea is not necessarily to learn to memorize enormous amounts of information,” says James Fozard,associate director of the National Institute on aging.“Most of us don’t need that kind of skill.Such specific training is of less interest than being able to maintain mental alertness.”Foard and others say they challenge their brains with different mental skills,both because they enjoy them and because they are sure that their range of activities will help the way their brains work.Gene Cohen,acting director of the same institute,suggests that people in their old age should engage in mental and physical activities individually as well as in groups.Cohen says that we are frequently advised to keep physically active as we age,but older people need to keep mentally active as well.Those who do are more likely to maintain their intellectual abilities and to be generally happier and better adjusted.“The point is ,you need to do both,” Cohen says,“Intellectual activity actually influences brain-cell health and size.” People who are cognitively healthy are those____.

American researchers say drinking tea may help strengthen the body’s defense system against infection. Doctors at Brigham and Women’s Hospital in Boston, Massachusetts, did the study. The team studied a chemical found in black, green, oolong and pekoe tea. This chemical is an amino acid called L-theanine. The scientists say it may increase the strength of gamma delta T cells. That’s the letter T, not the drink. Gamma delta T cells are part of the body’s defense. First, the researchers mixed some of these cells with antigens found in the amino acid(氨基酸). Antigens help the body react to infection. Then the scientists added some bacteria. Within twenty-four hours, the cells produced a lot of interferon, a substance that fights infection. Cells not mixed with the antigens did not produce interferon. In the second part of the study, eleven people drank five to six cups of black tea every day. Ten other people drank the same amount of instant coffee. That is dried coffee mixed with hot water. Two weeks later, and again two weeks after that, the researchers tested the blood of all twenty-one people. They also looked at what happened when they added bacteria to the blood cells. They found that the tea drinkers produced five times more interferon after they started drinking tea. The coffee drinkers did not produce interferon. Doctor Jack Bukowski led the study. He says the antigens added to the gamma delta T cells were responsible for the increased reaction to the bacteria. He says that the study also showed that the cells were able to remember the bacteria and fight them again the next time. Earlier research already has found that tea can help prevent heart disease and cancer. Doctor Bukowski says the new study must be repeated by more people. “If the findings prove to be true,” he says, “then tea drinking might also help protect against bacterial infections.” He says the amino acid L-theanine could be removed from the tea and used as a drug to strengthen the body’s defenses. 小题1:We may know from the text that ______ can be found in different kinds of tea. A．L-theanine B．Gamma delta T cells C．interferon D．bacteria 小题2:Tea may help strengthen the body’s defense system because it helps ______. A．to add some bacteria to the blood cells B．the body to produce more gamma delta T cells C．the body to produce more interferon D．to mix antigens with some of the cells in the body 小题3:According to Dr Bukowski, ______. A．the findings of the study have already proved to be true B．further study is needed to prove the findings true C．he has taken some amino acid L-theanine from tea and made a drug with it D．he is not sure whether tea help prevent heart disease and cancer 小题4:What would be the best title for this text? A．Tea Is Better than Coffee B．Our Body Needs Tea C．Tea Can Help Prevent Cancer D．Tea May Help Fight Infection

Scientists and researchers are interested in stem cells for several reasons.Although stem cells do not serve any one function,many have the capacity to serve any function after they are instructed to specialize.Every cell in the body,for example,is derived from first few stem cells formed in the early stages of embryological development.Therefore,stem cells extracted from embryos can be induced to become any desired cell type.This property makes stem cells powerful enough to regenerate damaged tissue under the right conditions.

Divorce is bad for environment US researchers raised a new theory on Monday: divorce is bad for the environment. The global trend toward higher divorce rates has created more households with fewer People， scientists at Michigan State University reported in the Proceedings of the National Academy of Sciences． More households means more houses，fuel and water are Heeded for them，the researchers wrote．“Globally，the number of households is increasing much faster than the number ofpeople，”said co-author “Jack” Liu in a telephone interview. “Even in regions with declining populationn, we see substantial increase in the number of households. Divorce is the main reason for reducingthe number of people in a household,” he said. The average divorced person’s household is about 40 to 50 percent smaller than the average married person’s household, Liu said. But whether there are three or six people in a house ,the amount of fuel needed to heat them is about the same. In the United States, divorced households used 74 billion kilowatt—hours of electricity and 2.850 trillion liters of water in 2005, half of which could have been saved if households had stayed the same size as when they were married. In the United States and 11 other countries between 1998 and 2002, if divorced households had combined to have the same average household size as married households, there could have been 7.4 million fewer households. The number of divorced households in those countries ranged from 40,000 in Costa Rica to almost 16 million in the United States around 2000. The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households. “If you really want to get divorced, maybe you can remarry with somebody else, or live together with somebody else you like”, Liu said. 1. In America when the number of households is_________, the number of people in a house is__________. A. increasing, decreasing B. decreasing, increasing C. increasing, increasing D. decreasing, decreasing 2. What does the word “substantial” in the third paragraph mean? A. Great B. Little C. Sudden D. Timely 3. How much electricity would have been saved without so many people getting divorced in America in 2005? A. 7.4 million kilowatt-hours B. 16 million kilowatt-hours C. 37 billion kilowatt-hours D. about 30 billion kilowatt-hours 4. The last paragraph is the writer’s_________for people. A. advice B. encouragement C. demand D. order

Empathy Last year, researchers from the University of Michigan reported that empathy, the ability to understand other people, among college students had dropped sharply over the past 10 years. __ 71 __ Today, people spend more time alone and are less likely to join groups and clubs. Jennifer Freed, a co-director of a teen program, has another explanation. Turn on the TV, and you’re showered with news and reality shows full of people fighting, competing, and generally treating one another with no respect. __ 72 __ There are good reasons not to follow those bad examples. Humans are socially related by nature. __ 73 __ Researchers have also found that empathetic teenagers are more likely to have high self-respect. Besides, empathy can be a cure for loneliness, sadness, anxiety, and fear. Empathy is also an indication of a good leader. In fact, Freed says, many top companies report that empathy is one of the most important things they look for in new managers. __ 74 __ “Academics are important. But if you don’t have emotional intelligence, you won’t be as successful in work or in your love life,” she says. What’s the best way to up your EQ (情商）? For starters, let down your guard and really listen to others. __ 75 __ To really develop empathy, you’d better volunteer at a nursing home or a hospital, join a club or a team that has a diverse membership, have a “sharing circle” with your family, or spend time caring for pets at an animal shelter. A．Everyone is different, and levels of empathy differ from person to person. B．Having relationships with other people is an important part of being human—and having empathy is decisive to those relationships. C．Humans learn by example—and most of the examples on it are anything but empathetic. D．“One doesn’t develop empathy by having a lot of opinions and doing a lot of talking,” Freed says. E. Empathy is a matter of learning how to understand someone else—both what they think and how they feel. F. Good social skills—including empathy—are a kind of “emotional intelligence” that will help you succeed in many areas of life. G. That could be because so many people have replaced face time with screen time, the researchers said.

Researchers studied about 50 4-,5-,and 7-year-olds in an effort to（试图,企图）identify coping strategies that can be carried out by children.The children listened to a series of short illustrated（有插图的）stories.Each story featured a child alone or with another person who came into contact with something that looked like a real or an imaginary frightening creature,such as a snake or a ghost.Children were asked to predict how intensely afraid each of the children in the stories were,to give a reason why each child felt that way,and to offer a way to help the child in the story feel less afraid.
In situations in which a child's fear was caused by real creatures,the researchers found,children would rather do something than think positive thoughts.In these situations,boys more often suggested fighting,while girls more often wanted to avoid the creature.
They also found that between ages 4 and 7,children show more understanding that people's thoughts and beliefs can both cause and reduce fear.While preschoolers tended to suggest pretending the imaginary creature was friendly,older children tended to suggest reminding themselves what the reality was.Therefore,the researchers say,preschoolers may benefit from seeing things in a more positive light ("Let's pretend the dragon is nice"),while older children may do better when they focus on what's real and what's not ("Dragons aren't real").

US researchers have found traces of an anc ient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life. The lake, which dates back some 3.4 billion years, appears to have covered as much as 80 square miles and was up to 1,500 feet deep, said the team from the U niversity of Colorado. “This is the first clear evidence of shorelines on the surface of Mars,”said Boulder’ s research associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research Letters. “The identification of the shorelines and accompanying geological evidence allows us to calculate the size and volume of the lake, which appears to have formed about 3.4 billion years ago.” Analysi s of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta (三角洲). “Finding shorelines is a great discovery to us,” said assistant professor Brian Hynek, adding it showed the lake existed at a time when Mars was thought to have been cold and dry. Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the Noachan epoch, about 4.1 billion to 3.7 billion years ago. The newly discovered lake is believed to date from the Hesperian era and postdates the end of the warm and wet period on Mars by 300 million years, according to the study. Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places on Earth have become the natural deposits of organic carbon and other markers of life. 小题1:The size of the lake found on Mars is ______. A．80 square miles B．1,500 square miles C．3.4 billion square miles D．300 million square miles 小题2:When the lake existed, the weather on Mars was ____. A．hot and wet B．wet and warm C．cold and dry D．cold and wet 小题3:Why do scientists think deltas near the lake may hold secrets about past life on Mars? A．Because similar places on Earth have become natural deposits of marker s of life. B．Because someone has put secrets about past life on Mars there. C．Because past life has been found in other deltas on Mars. D．Because some people are said to have already seen life marks there. 小题4:Which of the following statements is NOT true according to the passage? A．The Noachan epoch was a wet and warm era. B．The lake might have existed 3.4 billion years. C．The discovery can’ t fully prove that the Mars once hosted life. D．The lake traces prove that there exists life on Mars now.

Researchers questioned nearly 9,800 people over the age of 50 about their lives and found women were happier than men and enjoy life more in old age. Dr Elizabeth Breeze, one of the researchers, said that women could become happier as they get older as they no longer have to worry about looking after their families. She said:“There is a difference between the way men and women view their quality of life and they are influenced by slightly different things. Women are affected negatively by caring for someone else or if they are not in employment but if they see their children and family more they are positively affected.” “A strange thing happens to male actors, especially movie stars, in my experience,” said Helen Mirren, a 62-year-old Hollywood actress.“A young male actor feels that all the girls want him-he’s a star. As actors get older they bad-tempered for they have lost that sense of being in control of their destiny(命运).” Wealth also helps you live longer with the poorest people more than twice as likely to die earlier than the richest, researchers at University College London discovered. In some age groups. the difference was even greater. The poorest women between 60 and 74 are six times more likely to have died than the richest women of the same age. According to the study, you have more chances of living longer if you are married, educated to certain degree or a professional. single people are twice as likely to die early as those who are married or living with a partner. 小题1:What may be the best title of the passage ? A．Why Women Are Happier Than Men in Old Age . B．How to Live Longer. C．Women Happier Than Men in Old Age. D．The Difference between Women and Men in Old Age 小题2:What can we know from the passage？ A．Men should not worry about looking after their family any more in old age B．Male actors, especially movie stars are easy to get bad—tempered when they get older and older. C．The poorest women about the age of 50 can’t live longer than the richest women at the same age. D．Education has nothing to do with happy life in people’s old age. 小题3:What may be talked about if there is another paragraph as the ending ? A．Things that the old should do to be happier. B．The disadvantage of being actors. C．We should earn money as much as we can. D．How to become a professional.

Researchers at Massachusetts General Hospital for Children (MGHfC) have invented a new term that describes dangers associated with cigarette smoke: third-hand smoke. Study results published in January, 2009 discuss how third-hand smoke is especially dangerous for children. Have you ever walked into a room that had the smell of cigarette smoke, regardless of the fact that a fan was moving the air and no one was smoking at the time? This is what researchers are calling third-hand smoke — and it represents the poisonous deposits (存积物) that are left behind long after a cigarette is put out. Cigarette smoke contains gases and small particles that are deposited on every surface it comes in contact with, for example, the smoker’s hair and clothing, or the environment the cigarette was smoked in. It’s dangerous for young children who may crawl on polluted surfaces. Third-hand smoke is a serious health risk for our kids, especially those who live in the homes of smokers. Jonathan Winickoff, lead author of the study, explains, “When you come into contact with your baby, even if you’re not smoking at the time, he or she comes in contact with those poisons. And if you breast-feed, the poisons will transfer to your baby in your breast milk.” Winickoff adds however, that nursing a baby if you’re a smoker is still a better choice than bottle-feeding. Researchers involved in the study also surveyed more than 1,500 families in an effort to learn about adult attitudes regarding the danger third-hand smoke represents to their children and how that might affect smoking in the home. Approximately 95 percent of nonsmokers and 84 percent of smokers believe that secondhand smoke is dangerous for children. On the issue of whether third-hand smoke threatens the health of children, 65 percent of nonsmokers and 43 percent of smokers felt that third-hand smoke harms kids. When asked about rules regarding smoking in the home, approximately 88 percent of nonsmokers said they don’t allow smoking, while only 27 percent of smokers forbid smoking in the home. However, both non-smokers and smokers who felt that third-hand smoking was harmful to children’s health were more inclined to (倾向于) restrict smoking in their homes. 小题1:The study led by Jonathan Winickoff focused on _______. A．bad influences long after a cigarette is smoked B．third-hand smoke and secondhand smoke C．the bad effects of smoking on common people D．the terrible smell of cigarette smoke 小题2:How does the text explain what third-hand smoke is? A．By telling results of a survey. B．By giving statistics. C．By making comparisons. D．By giving an example. 小题3:The following measures to prevent the effect of third-hand smoke are effective except _______. A．keeping kids out of room when you smoke B．cleaning the house to get rid of poisons C．making yourself clean before contacting kids D．trying to forbid smoking in home

Researchers have announced the result of two studies on the health effects of the drug aspirin(阿斯匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer from a heart attack. The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇) levels. Earlier in the United States began a major aspirin study in the early 1980s. it included 22,000 healthy men doctors. All were between the ages of forty and eighty-four. More than 11,000 of the doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking. The doctors who took aspirin suffered 44% fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered from heart attacks. Ten of them died. 239 men who didn’t take aspirin suffered from heart attacks. Twenty-six of them died. The researchers said the doctors’ study provides clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said ,however, the result does not mean every man over the age of fifty should take aspirin. They said aspirin couldn’t help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first. 小题1: The passage tells us that the new use of aspirin is___________. A．to treat heart disease. B．to reduce pain while one suffers from a heart attack. C．to help old people to be more healthy. D．to reduce the chance of a heart attack in old men. 小题2:Aspirin can help those who___________. A．work as doctors B．are under 40 years old C．are fat and smoke cigarettes D．are older and healthy 小题3:From the experiment we can conclude that about _________ of people who suffered from heart attacks without aspirin died. A．7% B．11% C．19% D．44%

中文翻译Researchers at Stanford University ,who studied sedentary people for a year,
found that automated exercise reminder phone calls had about the same get-up-and-go power as calls from human couselors

Researchers who study relationships have discovered that a big difference between those who make new friends easily, and those who don’t, is that socially successful people tend to make eye contact with their conversation partners much more frequently than those who are less successful socially. In fact, you may be able to become much more socially successful by making this one simple change to your behavior. Most Americans prefer to have a lot of eye contact when they are talking with someone. When a person doesn’t make eye contact with them, they tend to think that the person is hiding something or the person doesn’t believe in himself/herself. When you are having a conversation and you want to leave a friendly impression, be sure to keep looking at that person frequently while you are talking. If it really bothers you to look directly into another person’s eyes, you can gaze generally at, not above, the eyebrow area or the bridge of the nose; this is close enough to the eye region that you will appear to be looking at the person’s eyes. But neither the hair or the shoulders have the same effect. Don’t stare at other people too intensely, otherwise, you will look aggressive(攻击性). Keep the majority of your focus on the other person. If you glance around the room too much, or look too frequently at other people, your conversation partner may guess that you are looking around for someone else you would rather talk with. You can lighten your nervousness by smiling more often, nodding, and by gazing at the entire face as well as the eyes. In addition, you can frequently look away for very short periods. When people get the sense that you are really paying attention to them, they will be much more likely to want to have conversations with you! 小题1:Which of the following is NOT the impression left by those who don’t make eye contact during the talk? A．They are not telling the truth. B．They are bored with the partner. C．They are lacking in confidence D．They are angry and ready to attack. 小题2: Besides the eyes of the partner, during the talk, you can look at his/her ___________. A．hair B．shoulders C．the bridge of the nose D．area above the eyebrows 小题3: From the passage, we can learn that ____________________. A．looking away during conversation should always be avoided. B．looking at a person frequently can give him/her a good impression. C．many Americans feel like being stared at for a long time. D．all successful people are good at making eye contact. 小题4:What would be the best title for the passage?
