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.

A.Effects of a stroke

B.Annual cost of stroke in the US

C.Definition and description of a stroke

根据以下材料，回答题

What Is Anthrax （炭疽） ？

There"s been a lot of talk about anthrax on the news lately. Some people are worried that anthrax may be connected to terrorist attacks or that terrorists may spread the germ that 51_______ the disease.

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.

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. This may sound scary， but even when a person comes 61_______ contact with the spores， it"s unlikely that he"ll get sick. 62_______ the bacteria do not get into the skin， digestive tract， or lung， the disease won"t develop.

Anthrax is not spread from person to person the way the flu can spread from family member to 63_______ member or classmate to classmate. Anthrax can almost always be successfully treated with antibiotics （抗生素） . Anthrax is very rare. Until recently， anthrax wasn"t even talked about because it was so rare-and it still 64_______ !Even with all of the anthrax cases you are hearing about right now， a person"s chances of getting anthrax are about the 65_______ as they were before you heard about anthrax on the news——very， very low.

回答题。

My family and I recently returned from a trip to Alaska, a place that combines supernaturalbeauty with a breathtaking amount of bear risks．I&39; 11 start with some facts at a glance :

WHERE ALASKA IS:Way the hell far from you．Beyond Mars．

HOW YOU GET THERE:You sit in a variety of airplanes for most of your adult life．

WHAT THEY HAVE THERE THAT WILL TRY TO KILL YOU:Bears．

I am quite serious about this．Although Alaska is now an official state in the United Stateswith modern conveniences such as rental cars and frozen yogurt, it also allows a large number ofadmitted bears to stride freely, and nobody seems to be the least bit alarmed about this．In fact, theAlaskans seem to be proud of it．You walk into a hotel or department store, and the first thing you see is a glass case containing a stuffed bear the size of a real one．Our hotel had two of these．Itwas what we travel writers call "a two-bear hotel"．Both bears were standing on their hind legs andstriking a pose that said: "Welcome to Alaska! I&39;m going to tear your arms off!"

This struck me as an odd concept, greeting visitors with a showcase containing a major localhazard．It&39;s as if an anti-drug organization went around setting up glass display cases containingstuffed drug smugglers(走私者), with little plaques (胸章)stating how much they weighed andwhere they were taken．

Anyway, we decided the best way to deal with our fear of bears was to become well informedabout them, so we bought a book, Alaska Bear Tales．Here are some of the chapter titles, which Iam not making up:

"They&39; ll Attack Without Warning"

"They&39; II Really Attack You"

"They Will Kill"

"Come Quick ! I&39; m Being Eaten by a Bear !"

"They Can Be Funny"

Ha-ha! I bet they can．I bet Mr．and Mrs．Bear will fight playfully over the remaining portionof a former tourist plumped up by airhne food．But just the same, I&39; m glad that the only actualbears that we saw were in the zoo．

What is the tone of the story？ 查看材料

A.Serious．

B.Complex．

C.Comic．

D.Disapproving．

阅读下文，回答题

It is difficult to imagine what life would be like without memory. (78) The meanings of thou-sands of everyday perceptions . the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory.

Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (79) Memory is involved when a rat gives up eating grain be-cause he has sniffed something suspicious in the grain pile. Memory is also involved when a six-year-old child learns to swing a baseball bat.

Memory exists not only in humans and animals but also in some physical objects and ma-chines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"--ready for instant use. An averageU.S. teenager probably recognizes the meaning of about 100,000 words of Engfish. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for ex- ample, the number of faces and places that the teenager can recognize on sight.

The use of words is the basis of the advanced problem-solving intelligence of human beings.

A large part of a person' s memory is in terms of words and combinations of words.

According to the passage， memory is considered to be__________. 查看材料

A.the basis for decision making and problem solving

B.an ability to store experiences for future use

C.an intelligence typically possessed by human beings

D.the data mainly consisting of words and combinations of words

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.

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 but not 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 ).

Visual memory helps us recall a place we have been to. 查看材料
