All people need to sleep. Sleep is a necessary process that promotes proper body functioning and can improve the quality of your life. Not only is the quantity of sleep important, but also the quality of sleep.
Your bedroom should be shaped to your taste and allow you to sleep in a peaceful environment. One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep. If your bedroom also functions as a command station for your life and work, the likelihood（可能性）of your sleeping being poor is rather high. Bedrooms should be designed, decorated and used for sleep mainly.TVs, computers and other things should not be in your bedroom if at all possible.
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness. Avoid hot food, caffeine, sugar and alcohol at least 4 to 6 hours before your sleep time.Develop a regular exercise program.Proper exercise and nutrition will help improve sleeping patterns. However, avoid exercising 2 hours before sleeping, since this may stimulate（刺激）your body and make sleeping more difficult.
Establish a pre-bedtime rule that will help you focus on sleep. You can try meditation (沉思), reading or deep breathing and relaxation. Your bedtime rule should be yours. Do not worry about it fitting into a specific category（种类）.Do what is best for you.
Things such as room temperature, noise and light levels and even your bed mattress（垫子） can have a lot of effect on the quality of sleep that you experience. Block out distracting（使人分心的） noises and lights. You are in your bedroom to sleep and not be distracted by environmental interferences (干扰).

For the past many centuries, people had been enjoying the benefits of green tea for the body. Many people would prefer drinking green tea than white tea and black tea, simply because of its distinct aroma(香味) not found in other types of tea. Nowadays, keeping the natural greenish color of tea leaves remained just like before. This is done by preparing the green tea just like the way it was prepared before—by washing the leaves right after pulling off them from the bush, then boiling them.
There have been many healthful claims saying that drinking green tea-based products help a lot in improving the general health of their body. For a long time, there has been many beliefs saying that green tea can help, cure beriberi disease(脚气病), treat wounds, and even prevent tiredness. Now modern technology determines that there are even added healthful benefits that include reducing the possibility of having a heart disease and helping people to lose more weight easily.
Besides, studies have found out that green tea has Polyphenols(多酚类), a type of flaonoid(类黄酮) that greatly reduces the amount of time of cell maturation. The flavonoid found in green tea is called EGCg- a stronger matter than Vitamin C and E. It is believed to be 20 times stronger than these mentioned vitamins.
Having two cups of green tea daily is a good routine for your body. However, most doctors would suggest drinking at least 4 cups a day is the best. You can slowly increase the amount of drinking it to allow your body to get used to it. There is nothing to lose but everything to gain in drinking green tea.

In the United States, 30 percent of the people have a “weight problem”. To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat.
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.

Ever since news of widespread food recalls caused by a carcinogenic dye（颜料） broke, there has been confusion over possible links to the country of the same name, but Sudan officials say there is no connection whatever.
Sudan1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
　　"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
　"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan1 to 4, are red dyes used for colouring solvents（溶剂）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very restricted diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins.
An example of the dangers of a restricted diet may be seen in the disease known as "beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ (病菌) . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest.
Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain.
Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice (糙米) somehow prevented or cured beri-beri--even that a lack of some ingredient (成分) in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

After moving to the United States, immigrant groups trying to fit in tend to choose high calorie fatty foods in an attempt to appear more American，a new study finds．That's one reason why immigrants approach US levels of obesity within 15 years of moving to America．
The researchers also did an experiment that measured whether or not the threat of appearing un-American influenced respondents' food choices．After being questioned about their ability to speak English，75 percent of Asian-Americans identified a typical American food as their favorite. Only 25 percent of Asian-Americans who had not been asked if they spoke English did the same.
When their American identity was called into question during a follow-up study, Asian-American participants also tended to choose typical American dishes，such as hamburgers and cheese sandwiches．In that experiment, 55 Asian-Americans were asked to choose a meal from a local Asian or American restaurant. Some participants were told that only Americans could participate in the study. Those who chose the more typical American fare ended up consuming an extra 182 calories，including 12 grams of fat and 7 grams of saturated fat（饱和脂肪）.
"People who feel like they need to prove they belong to a culture will change their habits in an attempt to fit in，"said Sauna Cheryan，an author of the study and assistant professor of psychology at the University of Washington." If immigrants and their children choose unhealthy American foods over healthier traditional foods across their lives，this process of fitting in could lead to poorer health." Cheryan added．
Social pressures，the study concluded, are at the heart of the problem．"In American society today, being American is associated with being white．Americans，who don't fit this image even if they were born here and speak English，feel that pressure to prove that they're American," said Cheryan．
【小题1】The author wants to show that __________.

A．more and more Asians enjoy high-calorie snacks

B．immigrants tend to eat American junk food to fit in

C．most Americans are at the risk of heart disease

Most schools forbid chewing gum(嚼口香糖), but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can. That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and
more. Scientists might even create anti-microbial (抗菌的) gums that cure bad breath.
Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use. For now, Stay Alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.

If you do not use your arms or your legs for some time, they become weak. When you start using them again, they slowly become strong again. Everybody knows this. Yet there are many people who do not seem to know that one’s memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by exercising it regularly. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong.
If a friend complains that his arms are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, or that he is just unlucky, and few of us realize that it is really his own fault. Not all of us can become very strong or very clever, but all of us can improve our memory by the same means — practice.
Have you ever noticed that people who cannot read or write usually have a better memory than those who can? Why is this? Of course, because people who can’t read or write have to remember things: they cannot write them down in a little notebook. They have to remember dates, prices, names, songs and stories, so their memory is exercised all the time.
So if you want a good memory, learn from those who cannot read or write: practise remembering.

D．how to remember dates and prices

Modern science suggests that a healthy lifestyle matters much to how long you can live and how well you live. Here are some tips for you to form a healthy lifestyle.
Keep a scientific diet. Keep in mind that sugar can be removed from our diet completely. Over intake of sugar is one of the main reasons for getting fat. Over intake of protein or fat and low intake of fiber can also lead to getting fat. We need only a few grams of protein every day to keep our body in order. Like rain to crops, not the more the better.
Be always in a good mood. There is a relationship between the mood and health. A good mood keeps you in high spirits. Thanks to the Internet, we can enjoy and learn much without going out. Take a look at some online shops and pick up some bargains, enjoy music and movies and chat with some good friends. Just keep happy.
Enough sleep. Two studies show the reasons why teens and adults don’t have enough sleep. With teens, a major reason is mobile phone use; with adults, it’s work. Meanwhile, a third study of young children shows that a lack of sleep in early life may lead to serious problems in future. Everyone needs at least 8-hour sleep to recover from tiredness and the hurt caused by hard work in the daytime.
Proper exercise. Do exercise to keep away from fatness. Because of the quick pace of modern life, you don’t have time to do exercise every day, but at least three times a week and 45 minutes each time.
【小题1】The author wrote the passage to _______.
