The sense of sound is one of our most important means of knowing what is going on around u

s. Sound has a waste product, too, in the form. of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.

Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.

There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.

Noise adds more tension to a society that already faces enough stress.

But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots(战车) from moving through the streets at night!

Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise—if we shout loudly enough about it.

Why are scientists surprised by the findings in their noise study？

A．Because the world is becoming increasingly noisy.

B．Because they have learned that noise is also is also a kind of pollution.

C．Because noise is an unwanted waste for human beings.

D．Because people knew little about noise before.

After a busy day of work and play, the body needs to rest. Sleep is necessary for good hea

lth. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.

There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.

Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement.

If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!

A good title for this passage is ______.

A．Sleep

B．Good Health

C．Play and Study

D．Work and Rest

nds, words, a system of word order, and grammar.Word order is more important in English than in some other languages.The sound system is very important in Chinese and in many African languages.

Language is always changing.The earliest known languages had complicated grammar but a small, limited vocabulary.Over the centuries, the grammar changed, and the vocabulary grew.For example, the English and Spanish people who came to America during the sixteenth and seventeenth centuries gave names to all the new plants and animals they found.In this way, hundreds of new words were introduced into English and Spanish vocabularies.Today life is changing very fast, and language is changing fast, too.

There are several major language families in the world.Some scientists say there are nine main families, but other scientists divide them differently.The languages in each family are related, and scientists think that they came from the same parent language.

Scientists find that hard-working people live longer than average men and women. Career wo

men are healthier than housewives. Evidence shows that the jobless are in poorer health than jobholders. An investigation shows that whenever the unemployment rate increases by 1%, the death rate increases by 2%. All this comes down to one point: work is helpful to health.

Why is work good for health？ It is because work keeps people busy away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest are those who are busy. (76) Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality. By work people come into with each other. By collective activity they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man spiritually and makes him ill.

Besides, work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.

(77) From the above we can come to the conclusion that the more you work the happier and healthier you will be. Let us work hard and study and live a happy and healthy life.

The underlined word "average" in Paragraph 1 means ______.

A．healthy

B．lazy

C．ordinary

D．poor

Protecting the heart, warding off cancer, easing the pain of arthritis -- the list of Vita

min E's possible benefits keeps getting longer. Now, because of two new studies, some researchers say the nutrient is so critical for older people that everyone over 65 should consider taking a daily supplement.

The latest finding comes from nutrition and immunology respected: Vitamin E boosts the immune system in older people. In an eight-month study of 88 seniors, the scientists found that those taking at least 200 international units of Vitamin E daily had stronger immune responses than those taking little or none. Alzheimer's disease. Researchers tracked 341 moderately senile patients. Those who popped 2,000 IU of Vitamin E took seven months longer to reach an advanced stage of the disease.

Rangit Kumar Chandra, a Vitamin E researcher at Memorial University of Newfoundland, Canada, says more studies are needed to learn who can benefit most and at what dose. Vitamin E thins the blood, so high doses can cause bleeding in people who also take blood thinning drags, even aspirin. Individuals with serious conditions should consult their doctors. But most people over 65, Chandra says, can take up to 200 IU with no side effects and great benefits.

What's the main idea of the passage？

A．People will be in perfect health if they take Vitamin E every day.

B．Study showed that people who took Vitamin E regained their Flexibility.

C．Vitamin E may help prevent Alzheimer's.

D．Vitamin E offers a range of advantage if old people take proper dose of Vitamin E every day.

Questions are based on the following passage. Cocoa contains chemicals calledflavanols （

Questions are based on the following passage.

Cocoa contains chemicals calledflavanols （黄烷醇） that may help reduce the risk of strokes and heart attacks by lowering blood pressure and improving the body"s use of insulin （胰岛素） .

Washington chocolate producer Steve Kumar said that is one reason dark chocolate is increasingly popular among his customers. "A lot of people are attracted by dark chocolate because they just decide they love it， and they also have been reading all about the health benefits of dark chocolate，" said Kumar.

But those benefits have not been confirmed by studies involving large numbers of people. Also， during the production of chocolate， a lot of flavanols are destroyed， while sugar and fats are added to contribute to flavor.

Scientists now want to learn the benefits of flavanols in their pure form.

They plan a four-year study of 18，000 adults， who will take pills of pure cocoa flavanols， in what is being called the largest test of its kind. Jo-Ann Manson， of the Brigham and Women"s Hospital in Boston， is the lead researcher. "This pill of cocoa flavanols will avoid having the calories and the sugar and the fat found in chocolate，" said Manson. The pills also won"t have any taste. Participants，divided in two groups， will take two identical pills a day. One group"s pills will contain flavanols， while the others will getplacebo （安慰剂） pills. "The amount of chocolate that it would take in order to have this amount of cocoa flavanols would be more than ten times the amount that people would ordinarily eat，" said Manson.

Whatever the outcome of the study， Kumar said he"s not worried about his business. "People like the experience of actually biting into a piece of chocolate，whatever their favorites are，" he said.

The flavanol benefits test is still in the early stage， so scientists are not sure when the participants will be handed their first chocolate pills.

What chemical in cocoa may do good to the heart according to the passage？查看材料

A.Fat.

B.Insulin.

C.Sugar.

D.Flavanols.
