Over the years, Americans have become used to salt.Most people have no idea how much salt they consume-on average, about 9 to 12 gram per person per day, according to the American Heart Association.That's twice the amount recommended by the government.
A new study last week showed eating even a little less salt could greatly help the heart.The scientists said the results would be thirteen percent fewer heart attacks, eight percent fewer strokes(中风), four percent fewer deaths and eleven percent fewer new cases of heart disease.
Researchers also found that the benefits would be greatest for African Americans and women.As a group, African Americans tend to have higher blood pressure than the general population, and "many studies suggest that they may be more sensitive to salt," says Dr.Kirsten Bibbins-Domingo, an epidemiologist(流行病学家)at the University of California, San Francisco.Her analysis found that a reduction of 3 gram of salt per day would reduce heart attacks 8% on average; among African Americans, that rate would drop 10%.A similar result was found in women, whose stroke risk dropped 8% with a 3-g reduction in salt intake; in men, the risk fell 5%.
They and public health professionals in the United States are interested in a national campaign to persuade people to eat less salt.
However, other scientists say such a campaign is an experiment with the health of millions of people.
Michael Alderman, a high blood pressure expert and professor at Albert Einstein College of Medicine in New York, says that eating less salt results in lower blood pressure.But he says studies have not clearly shown that lowering salt means fewer heart attacks or strokes.
“Salt has other biological effects. Calling for reductions in the national diet could have good effects, as well as harmful results. There is not enough evidence either way,”said Michael Alderman.
1.Eating too much salt may lead to the following EXCEPT________.
A.stroke B.heart disease C.high blood pressure D.lung cancer
2.What can we learn from the passage?
A.Most Americans take more salt than advised.
B.African women eat more salt than Americans.
C.One's origin determines how much salt he can eat.
D.Good health is just on the basis of having less salt.
3.The author's attitude toward the study is________.
A.cold B.objective C.subjective D.doubtful
4.What's the best title of the passage?
A.The Benefits of Eating Less Salt.

Most Americans have a city they like best. Over the years, American songwriters have described these feelings in music. More songs have been written about America's biggest city, New York, than about any other city. Many others dream about leaving their small towns to go there. They want to become rich and famous. Frank Sinatra sings about this dream in the most popular song written about New York.
Almost three-million people live in the middle western city of Chicago, Illinois. It is now America's third largest city. It used to be the second largest city. So, of course, it needed its own song. Judy Garland sings the song, "Chicago, Chicago. "
One of America's most exciting cities is Las Vegas, Nevada. In nineteen-sixty-four, Elvis Presley starred in a movie called "Viva Las Vegas." Here is the song from that movie. It is sung by the group Z-Z Top.
As we all know, one of the most beautiful cities in America is San Francisco, California. The most popular song about the city is called "I Left My Heart in San Francisco." Tony Bennett recorded it in nineteen-sixty-two. It sold more than three-million records.
Many people love Los Angeles, California. It is now America's second largest city. Los Angeles is popular because the weather is warm and the sun shines almost all the time. Randy Newman sings about his feelings for the city in the song, "I Love L.A." Not everyone, however, loves Los Angeles. Some people do not like all the big roads around the city. They like living in a smaller place. A place like San Jose, California. Dionne Warwick sings about going back to this city. The song is, "Do You Know The Way To San Jose."

Increasingly, over the past ten years, people-especially young people have become aware of the need to change their eating habits, because much of the food they eat, particularly processed food, is not good for the health. Consequently, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers(化肥)widely used in farming today.
Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple terms, this means that the soil has been nourished by unused vegetable matter, which provides it with essential vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount but not the quality of foods grown in commercial farming areas.
Natural foods also include animals which have been allowed to feed and move freely in healthy pastures(生活状况). Compare this with what happens in the mass production of poultry(家禽): there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins.
There are other aspects of healthy eating which are now receiving increasing attention from experts in diet. Take, for example, the question of sugar. This is actually a nonessential food! It is not that sugar is harmful in itself. But it does seem to be additive: the quantity we use has grown steadily and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals and no fibre.
1.People have become more interested in natural foods because ________.
A. processed food is not good for the health
B. they want to eat food that is more tasty
C. they want a change of diet
D. they want to be fashionable
2.The reason of using chemicals and fertilizers is to ________.
A. improve the quality of foods
B. increase the quantity of foods
C. provides people with essential vitamins
D. supply people with more energy
3.Battery chickens cannot be called “natural food” because ________.
A. they all live together
B. they are tasteless
C. their eggs have no vitamins
D. they are not allowed to move round and eat freely

Most, if not all, Chinese have become richer thanks to 28 years of reform and opening up. But are we any happier?
Various surveys attempt to answer this question. Though experts have presented varying percentages based on different standards, their answers tend to find we are generally happier, and the number of optimists rises each year. The Chinese Academy of Social Sciences’ 2006 Blue Book on social progress says 70 per cent of rural and urban citizens surveyed in 2005 reported a feeling of happiness and were optimistic about their futures.
But each survey shows a worrisome fact that 10 per cent, at the lowest, of citizens were not content with their lives or not hopeful about the future. We cannot be content with the fact that at least 130 million of our countrymen are not happy.
Although a sense of happiness remains a luxury(奢望)for many of our countrymen because of poverty, we agree wealth is not the only factor of happiness. For most of us, except the extremely rich and naturally born optimists, there simply are too many variables (可变物) that may kill the feeling of happiness. These include, but are not limited to, rising housing prices, tight and instable job market, back-breaking schooling expenses and medical bills.
The most common one, however, is a low sense of security (安全). Some experts pointed that in the low-and-middle income group there was too much uncertainty regarding employment, income, housing, medical situations, and education. How can you feel happy when you always have to prepare yourself for the unexpected?
It may be beyond the government’s reach, not to mention duty, to guarantee (保证) higher income for every citizen. But it does have a burden to create an environment where all citizens can feel a reasonable level of security.
1.From the second paragraph we learn _____________________.
A.70 % of Chinese people feel happy and optimistic about their future |
B.the data and the conclusions of the surveys are the same |
C.the surveys about the sense of happiness were carried out in 2006 |
D.the purpose of the surveys is to find out the percentage of rich people |
2.The following factors of happiness are mentioned in the passage EXCEPT _________.
A.security | B.environment | C.wealth | D.employment |
3.The underlined word “countrymen” in Paragraph 3 refers to ___________.
A.people from the countryside | B.people from cities |
C.people from all countries | D.Chinese citizens |
4. According to the passage, the author tends to hold the view that _________.
A.the wealthier we get, the happier we become |
B.though we get wealthier, we do not feel happier |
C.it is the government’s duty to raise every citizen’s income |
D.the government should make sure all citizens feel a good level of security |

There have been big changes in the attitudes of most parents over the last few years. Physical punishment is banned in schools in most countries ,and in many countries, there are moves to ban all physical punishment of children even at home. However, many parents still believe that they have the right to use some physical punishments to deal with certain misbehavior at certain ages.
It ‘s easy to find reasons to allow some physical punishments. One issue is that many parents find it very difficult to abandon physical punishment completely. Parents argue that this was the way they were brought up and that it didn’t do any harm to them. They believe that for the child’s sake they have the right to discipline the child in any way they consider fit ,including using some physical punishments. The other one is that physical punishment can be quick and effective. There is not much point reasoning with a screaming child in the supermarket.
However, there are several reasons why we should stop using physical punishment. One point is that most parents are not trained to deal with misbehaving children. They don’t have enough resources or choices to handle the situation. As a result, they immediately react by hitting the child even if there are other solutions to the problem. Another point is that unless people are challenged or forced to change their belief, they may keep following negative habits. An example is seat belt use ——now most people wear seat belts without thinking, while years ago the idea of using seat belts was strange to most people. In the same way, banning physical punishment will force people to change their habits.
In conclusion, parents have to change some of their belief and ideas about how children should be raised. It is possible to avoid the use of physical force,and doing so will help us move closer to the dream of removing violence from our society.
1.According to the first paragraph, many parents think that _____
A. they are free to use physical punishment on their children
B. most of the children behave badly in their daily life
C. they have changed their attitudes towards their children
D. physical punishment is effective to educate their children
2. Many parents won’t give up physical punishment because _____.
A. they are disappointed with their children
B. they were brought up just in the same way
C. they don’t want to hurt their children badly
D. they don’t know what to do with their children
3.The author gives the example of using seat belts in order to show _____.
A. most people are used to wearing seat belts
B. it’s not difficult to change some negative habits
C. seat belts are really very necessary and useful
D. people won’t change their old habits unless forced
4.The main purpose of the author in writing this passage is to _____.
A. talk about a ban on using physical punishment
B. tell us we should educate our children in other ways
C. advise parents to give up using physical punishment
D. suggest physical punishment should be used at home

Celebrity (名人) has become one of the most important representatives of popular culture. Fans used to be crazy about a specific film, but now the public tends to base its consumption (消费) on the interest of celebrity attached to any given product. Besides, fashion magazines have almost abandoned (given up) the practice of putting models on the cover because they don’t sell nearly as well as famous faces. As a result, celebrities have realized their unbelievably powerful market potential, moving from advertising for others’ products to developing their own.
Celebrity clothing lines aren’t a completely new phenomenon, but in the past they were typically aimed at the ordinary consumers, and limited to a few TV actresses. Today they’re started by first-class stars whose products enjoy equal fame with some world top brands. The most successful start-ups have been those by celebrities with specific personal style. As celebrities become more and more experienced at the market, they expand their production scale rapidly, covering almost all the products of daily life.
However, for every success story, there’s a related warning tale of a celebrity who overvalued his consumer appeal. No matter how famous the product’s origin is, if it fails to impress consumers with its own qualities it begins to resemble an exercise in self-promotional marketing. And once the initial (最初的) attention dies down, consumer interest might fade, loyalty returning to tried-and-true labels.
Today, celebrities face even more severe embarrassment. The pop-cultural circle might be bigger than ever, but its rate of turnover has speeded up as well. Each misstep threatens to reduce a celebrity’s shelf life, and the same newspaper or magazine that once brought him fame has no problem picking him to pieces when the opportunity appears. Still, the ego’s(自我的)potential for expansion is limitless. Having already achieved great wealth and public recognition, many celebrities see fashion as the next frontier to be conquered. As the saying goes, success and failure always go hand in hand. Their success as designers might last only a short time, but fashion—like celebrity—has always been temporary.
1.Fashion magazines today ________.
A. seldom put models on the cover
B. no longer put models on the cover
C. need not worry about celebrities’ market potential
D. judge the market potential of every celebrity correctly
2.A change in the consumer market can be found today that ________.
A. price rather than brand name is more concerned
B. producers prefer models to celebrities for advertisements
C. producers prefer TV actresses to film stars for advertisements
D. quality rather than the outside of products is more concerned
3.The underlined sentence in paragraph 4 indicates that any wrong step will possibly ________.
A. decrease the popularity of a celebrity and the sales of his products
B. damage the image of a celebrity in the eyes of the general public
C. cut short the artistic career of a celebrity in show business
D. influence the price of a celebrity’s products
4.The passage is mainly about ________.
A. celebrity and personal style B. celebrity and markets potential
C. celebrity and fashion design D. celebrity and clothing industry
