Are you having too much salt? You might not think so, but people in China eat on average (平均) about 12 grams of salt each day, that is much higher than the 6 grams suggested by the World Health Organization. You could be eating too much without realizing it, because about 75% of the salt we eat is already in the food we buy, such as bread, sauces, soups and sausages.
What problems can eating too much salt cause? To answer that question, first let’s take a look at what salt is.
Salt is a chemical compound. It is made of sodium (钠) and chloride (氯化物). Salt is used to keep and flavor foods. A small amount of salt is important for good health because our bodies need sodium and chloride to work.
But past studies have found that people who eat more salt than they need tend to have high blood pressure. Eating too much salt has also been connected with other conditions, such as heart and kidney (肾) problems.
If you want to cut down on salt, the good news is, there are plenty of simple things to do. Here are some tips:
*Cut back on high salt foods.
Most foods contain some salt. But some foods such as cheese, bacon, pickles (泡菜), smoked fish and chips are almost always high in salt because of the way they are made. You can still enjoy them, but try to have these in smaller amounts, or eat them less often.
*Choose reduced salt bread and breakfast cereals.
Bread and breakfast cereals (谷物) are major source of salt in the diet, not that they’re necessarily high in salt but because we eat a lot of them. For these foods, there can be a really big difference between different types and brands. So next time you’re shopping, take the time to compare the salt levels on a few similar products. And always try to choose the ones lower in salt.
*Avoid adding salt to cooking and at table. Instead, you could use herbs and spices (香料) such as garlic (大蒜) and lemon juice to add flavor to meals.
【小题1】Many people in China don’t realize they are eating too much salt because ______.
| A．salty food tasted better than reduced salt food |
| B．they do not calculate the amount of salt they eat |
| C．about 3/4 of the salt we eat is already in the food we buy |
| D．few people experience problems from eating too much salt |
| A．cut back on food with less salt |
| B．eat less heavily salted food |
| C．eat as much reduced salt bread as is wanted |
| D．stop eating bread and breakfast cereals |
| A．To warn people of food containing too much salt. |
| B．To inform people of the right amount of salt taken each day. |
| C．To advise people to be careful about the amount of salt they eat. |
| D．To promote (促进) the right way to make reduced salt food. |

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic talked about by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life can be longer.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing with hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to make human beings in large quantities. In the past few years, scientists have succeeded in cloning babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
【小题1】What does “these two killers” in the second paragraph refer to?
| A．Gene technology and another treatment of the two diseases. |
| B．The two murderers who killed the cloned baby. |
| C．Hereditary disease and cancer. |
| D．Cancer and heart disease. |
| A．Using gene technology, a scientist finds the wrong gene and corrects it. |
| B．Using gene technology, people with hereditary diseases can live longer. |
| C．Using gene technology, human babies can also be cloned. |
| D．Doctors can cure cancer and heart disease with the help of gene technology. |
| A．Explaining that gene technology will also do great harm to human race. |
| B．Telling the readers the positive effects gene technology has on people’s life. |
| C．Expressing the writer’s idea that gene technology will benefit people. |
| D．Informing people that gene technology helps clone babies in large quantities. |

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 |
| 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 |
| 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 |
| A．Tea Is Better than Coffee | B．Our Body Needs Tea |
| C．Tea Can Help Prevent Cancer | D．Tea May Help Fight Infection |

Forgiving someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don’t think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger can change your well-being.
When cartoon book characters like the Incredible Hulk get angry, they change colours and often gain special power. In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, says holding on to anger and hatred can harm your physical and mental health. Two new studies seem to show the same idea.
The studies find that people who are able to forgive feel less stress, less back pain, and less depression(抑郁). They also have fewer headaches, lower blood pressure, and fewer problems on sleeping.
So it doesn’t matter if your anger is caused by the traffic or other things. Learning to let it go is important. Techniques such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.
Forgiveness does not mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.
【小题1】The author of the passage tries to make his viewpoint clear__________.
| A．by raising his own examples |

Risk of death is 3.5 to 5 times greater for obese (肥胖的) smokers than it is for people who have never smoked and are at a normal weight, according to a study published in the November, 2006 issue of the American Journal of Preventive Medicine.
The study, which began with a self-administered questionnaire taken between 1983 and 1989, asked more than 80,000 radiologic technologists aged 22 to 92 questions about age, height, weight and smoking behavior.
BMI (body mass index) was calculated, with a BMI of 30 to 34.9 being considered obese, and 35 and over being very obese. Smoking behavior was analyzed by looking at a person's tobacco consumption level, number of years smoked, and current smoking status. Researchers then followed participants through December of 2002, noting the number of deaths that occurred.
The study involved researchers from the National Cancer Institute, the University of Minnesota and the American Registry of Radiolegic Technologists.
Key Findings:
20 percent of obese adults in the United States smoke.
Obese smokers face a greater risk of death from cancer and circulatory disease.
Current smoking is a greater risk factor for death by cancer than obesity is, generally speaking.
The higher a person's pack-years (number of packs smoked per day times the number of years smoked) are, the greater the risk of death.www.zxxk.com
Men and women of all ages faced an elevated risk of death due to circulatory disease as BMI increased. And for those who were both obese and currently smoking, risk of circulatory disease increased 6 to 11 times under the age of 65, as compared to their never-smoking, normal weight counterparts.
While it's not surprising that obesity coupled with smoking is a recipe for trouble, it is important to highlight this growing health concern in America today.
Taking Charge of Your Health
Making healthy choices can be difficult when we're constantly exposed to products that are dangerous to our health, but it's not impossible. With education and some motivation, we all have the ability to make lasting changes for the better. If you're an overweight smoker worried about gaining weight due to quitting, take heart. It's never too late to change your course and even reduce damage to some extent.
【小题1】60. What is the American Journal of Preventive Medicine?

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community.
"How Yoga Can Wreck Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself.
The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison.
Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself.
The reasons that yoga causes "serious injury”, according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures.
Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there.
We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer.
【小题1】The underlined word is best replaced by __.
| A．Injure | B．Benefit | C．Push | D．Shape |
| A．All physical activities are equally harmful. |
| B．Yoga causes much less injuries than other physical activities. |
| C．Similar researches have been done before. |
| D．Yoga, like any other form of exercise, can hurt people. |
| A．Teachers lack the knowledge of students’ limits. |
| B．Modern lifestyle decreases our flexibility. |
| C．The body doesn’t tell when you are in real pain. |
| D．Students themselves might not be in good physical condition. |
| A．It’s a shame not to practice yoga. |
| B．One should push the limits in order to be perfect. |
| C．The majority should give up yoga for it may cause harm. |
| D．One should enjoy the physical and mental benefit that yoga brings. |

Every hour spent in watching TV, DVDs and videos as an adult reduces lifespan by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years.
The research shows that a sedentary（久坐的） lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities it offers for unhealthy eating.
The researchers set out to calculate the overall risk to lifespan from watching television. Their research involved more than 11,000 people over the age of 25.
Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be connected with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity."
The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data.
But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States.
Earlier this year, a separate study suggested the risk of developing diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box.
England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks. We hope these studies will help more people realize that there are many ways to get exercise."
【小题1】We can learn from the passage that .
| A．whether you watch TV or not has nothing to do with how long you will live |
| B．if an adult watches TV for six hours every day, he will probably die five years earlier |
| C．physical inactivity and obesity won't shorten your life |
| D．a sedentary lifestyle offers huge benefits. |
| A．The longer one watches TV every day, the shorter he lives. |
| B．The conclusion of the study is unbelievable because it's based on Australian data. |
| C．Watching TV does greater harm to health than smoking and obesity |
| D．Watching TV harms children as much as adults. |
| A．People in the United Kingdom watch TV longer than those in the United States. |
| B．That a sedentary lifestyle carries additional risks isn't supported by other studies. |
| C．Watching TV for two hours a day will increase the risk of illnesses or dying early by 20%. |
| D．Australian data is much different from that of other countries. |
| A．inform the readers of a research on watching TV |
| B．tell the readers large amounts of people often watch TV |
| C．tell the readers watching TV is also a good way to relax |
| D．warn the readers of the harm of watching TV and hope that they do sports |

Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, king of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist (免疫学家)， encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
【小题1】The kings of France and England in the 16th century closed bath houses because________.
| A．they lived healthily in a dirty environment |
| B．they thought bath houses were too dirty to stay in |
| C．they believed disease could be spread in public baths |
| D．they considered bathing as the cause of skin disease |
| A．Afraid | B．Curious | C．Approving | D．Uninterested |
| A．By providing examples. |
| B．By making comparisons. |
| C．By following the order of time. |
| D．By following the order of importance. |
| A．To stress the role of dirt. |
| B．To introduce the history of dirt. |
| C．To call attention to the danger of dirt. |
| D．To present the change of views on dirt. |

Bursting into the classroom from recess, 15 children take their seats and face the woman they know as Ms. Yang.
“What day is it today?” she asks, in Mandarin Chinese.
“Confucius’ birthday!” the fifth graders shout in Mandarin.
“Why do we celebrate Confucius’ birthday?”
“Because he’s the greatest teacher in the history of China!” exclaims a brown-haired girl. She is speaking Mandarin.
English is rarely heard in Lisa Yang’s class at the Chinese American International School(CAIS), despite the fact that few students are native speakers of Mandarin.
The United States is actively trying to increase the group of students in “critical languages” such as Mandarin. The students at CAIS are way ahead in such a trend.
Founded 25 years ago, this small private school in San Francisco, USA, does what few other American schools do: It produces fully fluent speakers of Mandarin Chinese, by far the most commonly spoken language in the world.
Mandarin Chinese is suddenly hot in American schools. As China becomes the world’s leading economy sometimes this century, schools in the U. S. are scrambling to add Mandarin to their list of foreign languages or expand Chinese programs already in place.
“It really is almost unprecedented. People are looking at China as a force to be reckoned with… And to ensure that the U. S. has the ability to conduct trade, and to work with the Chinese. Certainly having an understanding of Chinese language and culture is an advantage,” said Marty Abbott of the American Council on the Teaching of Foreign Languages(ACTFL).
To develop Chinese-language programs has not been smooth. A shortage of trained teachers has made it difficult for some schools to join the race. When schools do get teachers, they often hire them straight from China, and the teachers usually suffer culture shock when they come to the U. S.
Robert Liu remembers his first two years in an American classroom It was not an easy adjustment. “In China, students respect their teachers,” he said. Liu found that American students, however, expect an active teaching style. He had to use games to engage them rather than lectures.
To avoid many of the problems with foreign teaching styles, the CAIS has been working with the Chinese government to improve training of teachers who are sent to the U. S.
【小题1】Which of the following is NOT true according to the passage?
| A．Understanding Chinese language and culture is helpful to work with Chinese. |
| B．Chinese-language programs have met trouble during the development. |
| C．Many other American schools do the same as CAIS, founded 25 years ago. |
| D．A lack of trained Mandarin Chinese teachers is a problem for the programs. |
| A．To adapt themselves to the American life styles. |
| B．To communicate with the American students. |
| C．To get along well with the American students. |
| D．To be fit for the cultural differences in teaching styles. |
| A．climbing | B．rushing |
| C．changing | D．beating |
| A．the students in Lisa Yang’s class usually speak Chinese |
| B．There are few American students in Lisa Yang’s class |
| C．We celebrate Confucius’ birthday because he’s the greatest history teacher |
| D．in America the students don’t respect their teachers |
