回答题:

Facts about Stroke

1Every 45 seconds, someone in America has a stroke. Every 3.1 minutes, someone dies of one.

Stroke killed an estimated 167,661 people in 2000 and is the nation&39;s third leading cause of death, ranking behind diseases of the heart and all forms of cancer. Stroke is a leading cause of serious ,long-term disability in the United States.

2 Stroke is a type of cardiovascular(心血管的) disease. It affects the arteries(动脉) leading to and within the brain. A stroke occurs when a blood vessel that carries oxygen and nutrients(营养物) to the brain is either blocked by a clot(凝块) or bursts. When that happens,part of the brain cannot get the blood(and oxygen)it needs,so it starts to die.

3The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can&39;t reach the region that controls a particular body function, that part of the body won&39;t work as it should. If the stroke occurs toward the back of the brain, for instance, it&39;s likely that some disability involving vision will result. The effects of a stroke depend primarily on the location of the obstruction(阻塞) and the extent of brain tissue affected.

4The American Stroke Association has identified several factors that increase the risk of stroke.

The more risk factors a persor has,the greater the chance that he or she will have a stroke. Some of these you can&39;t control, such as increasing age, family health history, race, and prior stroke. But you can change or treat other risk factors to lower your risk. Factors resulting from lifestyle. or envi-ronment can be modified with a healthcare provider&39;s help. Some of these include : high blood pres-sure,current smoking,heart disease,and high red blood cell count.

5A stroke can happen to anyone at any moment. In fact about 600,000 people have strokes every year. For many years, there was no hope for those suffering a stroke. However, recent break-throughs have led to new treatments. For the treatments to work, the person must get to a hospital immediately.

Few Facts about Singapore

1 Singapore is an independent city state in southeastern Asia,consisting of one major island——the Singapore Island——and more than 50 small islands, located off the southern tip of Malay. The city of Singapore, the capital of the country, is at the southeastern end of the Singapore Island ; it is one of the most important port cities and commercial centers of Southeast Asia. The total area of the re-public is 640 sq. kin.

2 Low lying Singapore Island has no outstanding relief(轮廓鲜明的) features. A central area of hills rises to the maximum height of 176 m. The country has a wet tropical climate,with an average annual temperature of 27.20℃. The average annual rainfall is 2,413 mm;the wettest months are November through January.

3 Singapore is governed under a constitution of 1959. A president,elected to a four-year term is head of state, and a prime minister is head of government. The president used to be selected by Parliament, but by a 1991 constitutional amendment(修正案), the president is now elected directly by the people. The Parliament is the law making, body with its 81 members popularly elected.

4 In the late 1980s the country had some 290 primary schools with 278,300 pupils and 160 secondary schools with 200,200 students. The main institutions of higher education are the Nati"onal University of Singapore, several technical colleges, and a teachers college.

5 Singapore has one of the highest standards of living of any country in Asia. In the late 1980s the gross domestic product was estimated at $ 23.7 billion, or $ 8,870 per person. The fishing industry is centered on the port of southwestern Singapore island. Industry has grown rapidly since the 1960s, and Singapore now produces a diversity (多样化的)of goods, including chemicals, electronic items, clothing, and processed foods, etc. Shipbuilding and petroleum refining are also important.

根据以下材料,回答题

What Is Anthrax (炭疽) ?

Federal officials and police are investigating this and taking 52_______ to protect us.

In the meantime, it"s important not to panic over anthrax. The chances that you and your family 53_______ at risk are very tiny. One of the ways you can feel better is to learn about anthrax.

When you know what it is and 54_______ you can get it, it doesn"t seem quite as scary.

So, what 55_______ is anthrax?

Here are the facts on anthrax:

Anthrax is a bacterial infection caused by a germ. Although it"s most common in farm 56_______ ,like sheep, cows, pigs, horses, and goats, there"s a very small chance that people can get it, too.

Anthrax spores (孢子) a version of the germ in a protective shell that can live in the soil for years)cause the disease. People may get anthrax if they are exposed to anthrax 57_______ .But here"s the important part: just being exposed to these spores doesn"t mean that a person will get 58_______

For a person to get sick, he would have to breathe in thousands of these spores all the way into his 59_______ . Or he"d have to eat meat contaminated with anthrax or handle 60_______ that has anthrax spores.

根据下面材料,回答题。

The Need to Remember

Some people say they have no memory at all: "I just can&39;t remember a thing!" But of course,we all have a memory. Our memory tells us who we are. Our memory helps us to make use in the present of what we have learnt in the past.

In fact, we have different types of memory. For example, our visual memory helps us recall facts and places. Some people have such a strong visual memory, they can remember exactly what they have seen, for example, pages of a book, as a complete picture.

Our verbal (言语的) memory helps us remember words and figures we may have heard butnot seen or written: items of a shopping list, a chemical formula, dates, or a recipe.

With our emotional memory, we recall situations or places where we had strong feelings,perhaps of happiness or unhappiness. We also have special memories for smell, taste, touch and sound, and for performing physical movements.

We have two ways of storing any of these memories: Our short-term memory stores items for up to thirty seconds- enough to remember a telephone number while we dial. Our long-term memory, on the other hand, may store items for a lifetime. Older people in fact have a much better long-term memory than short-term. They may forget what they have done only a few hours ago, but have the clearest remembrance (记忆) of when they were very young.

Psychologists tell us that we only remember a few facts about our past, and that we invent the rest. It is as though we remember only the outline of a story. We then make up the details. We often do this in the way we want to remember them, usually so that we appear as the heroes of our own past-- or maybe victims needing sympathy (同情).

根据下面材料,回答题。 Disease, Diagnosis, Treatment and PreventionDisease may be defined

根据下面材料,回答题。

Disease, Diagnosis, Treatment and Prevention

Disease may be defined as the abnormal state in which part or all of the body is not properly adjusted or is not capable of carrying on all its required functions. There are marked variations in the extent of the disease and in its effect on the person.

In order to treat a disease, the doctor obviously must first determine the nature of the illness--that is, make a diagnosis. A diagnosis is the conclusion drawn from a number of facts put together.

The doctor must know the symptoms, which are the changes in body function felt by the patient;and the signs (also called objective symptoms) which the doctor himself can observe. Sometimes a characteristic group of signs (or symptoms) accompanied a given disease. Such a group is called a syndrome. Frequently certain laboratory tests are performed and the results evaluated by the physician in making his diagnosis.

Although nurses do not diagnose, they play an extremely valuable role in this process by observing closely for signs, encouraging the patient to talk about himself and his symptoms, and then reporting this information to the doctor. Once the patient&39;s disorder is known, the doctor prescribes a course of treatment, also referred to as therapy. Many measures in this course of treatment are carried out by the nurse under the physician&39;s orders.

In recent years physicians, nurses and other health workers have taken on increasing responsibilities in prevention. Throughout most of medical history, the physician&39;s aim has been to cure a patient of an existing disease. However, the modern concept of prevention seeks to stop disease before it actually happens -- to keep people well through the promotion of health. A vast number of organizations exist for this purpose, ranging from the World Health Organization (WHO)on an international level down to local private and community health programs. A rapidly growing responsibility of the nursing profession is educating individual patients toward the maintenance of total health--physical and mental.

By disease it means the condition in which one or more parts of the body fail to function properly. 查看材料

What Is a Dream?

For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however,think that dreams are an important part of our lives. In fact, many experts believe that dreams can tell us about a person&39;s mind and emotions.<br>

Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.<br>

The Austrian psychologist, Sigmund Freud, was probably the first person to study dreams scientifically. In his famous book, The Interpretation of Dreams (1900), Freud wrote that dreams are an expression of a person&39;s wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life.<br>

The Swiss psychiatrist Carl Jung was once a student of Freud&39;s. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.<br>

Modern-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams are tightly linked to a person&39;s daily life, thoughts, and behavior. A criminal, for example, might dream about crime.<br>

Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults. According to Domhoff, dreaming is a mental skill that needs time to develop.<br>

He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in men&39;s dreams are often other men, and the dreams often involve fighting. This is not true of women&39;s dreams. Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones.<br>

Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. However, one thing they agree on this: If you dream that something terrible is going to occur, you shouldn&39;t panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. It&39;s important to remember that the world of dreams is not the real world.

Not everyone agrees that dreams are meaningful. 查看材料

根据以下材料,回答题

American Society

When foreigners are sometimes asked what seems most strange about American society,somewhere on the top of the list will be the fact the average citizen is allowed to possess guns.

Although it is true that many people carry guns legally in the United States, it is also known that many who possess guns carry illegally. Others, who don"t have guns, feel that guns can be acquired quite easily. A recent survey indicated that many high school students, especially in the inner cities, can acquire gun with little difficulty.

Although most people would never want to own a gun, others have taken up hunting as a sport and enjoy hunting wild game in season. Hunting for deer and duck in fall and winter is very much a part of the American culture.

Also, some farmers in rural areas who raise cattle and sheep feel they need to protect their animals against wolves that attack their herds and flocks at night. To defend and support their rights to possess firearms the National Rifle Association (NRA) was founded in 1871. The main importance of this organization has been its efforts to prevent strict gun control legislation. The NRA has great political support in small towns and rural areas, especially in the West and the South,where hunting is especially popular. Those who favor the right to possess guns insist that the Constitution provides the right of people "to keep and bear arms". They believe that gun control laws will not solve the problem of crime and violence in America.

Recent events in America, however, have shown that the question of gun possession is now out of control and strong voices have called for immediate action to be taken. In seemingly peaceful schools students have gone into classrooms and opened fire upon their classmates.

America has been shocked by such incidents which seem to occur with greater frequency. The periodic deaths of innocent citizens and even foreign visitors from guns have forced legislators to pass laws to stop these senseless killings.

The day may not be far off when America will be transformed from a gun culture to one which controls their use and possession.

What is most unusual about American society? 查看材料

A.Many Americans acquire guns illegally.

B.Ordinary people can possess guns legally.

C.The average citizen does not try to possess guns.

D.Many school children carry guns legally.
