Thirty-two people watched Kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in gunman cruelty? Was it lack of feeling about one’s fellow man?

Not so, say scientists John Barley and Bib Fatane. These men went beyond the headlines to seek the reasons why people didn’t act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency.

Suppose you see a middle-aged man fall to the side-walk. Is he having a heart attack? Is he in a coma from diabetes(糖尿病)? Or is he about to sleep off a drunk?

Is the smoke coming into the room from a leak in the air conditioning? Is it steam pipes? Or is it really smoke from a fire? It’s not always easy to tell if you are faced with a real emergency.

Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won’t get the help he needs.

The researchers found that a lot depends on how many people are around. They had college students in to be tested. Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the tests. Then she went into the next room. A curtain divided the testing room and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of this had been pre-recorded on a tape-recorder.

Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.

In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn’t. They do not feel any direct responsibility.

Are people bothered by situations where people are in trouble? Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person’s trouble. But they did not act. They were in a group. Their actions were shaped by the actions of those they were with.

1. The purpose of this passage is ____________.

A. to explain why people fail to act in emergencies

B. to explain when people will act in emergencies

C. to explain what people will do in emergencies

D. to explain how people feel in emergencies

2.The researchers have conducted an experiment to prove that people will act in emergencies when ____________.

A. they are in pairs B. they are in groups

C. they are alone D. they are with their friends

3. The main reason why people fail to act when they stay together is that ____________.

A. they are afraid of emergencies

B. they are unwilling to get themselves involved

C. others will act if they themselves hesitate

D. they do not have any direct responsibility for those who need help

4.The author suggests that ____________.

A. we shouldn’t blame a person if he fails to act in emergencies

B. a person must feel guilty if he fails to help

C. people should be responsible for themselves in emergencies

D. when you are in trouble, people will help you anyway

Evaluating Sources (來源) of health Information

Making good choices about your own health requires reasonable evaluation. A key first step in bettering your evaluation ability is to look carefully at your sources of healthy information. Reasonable evaluation includes knowing where and how to fins relevant information, how to separate fact from opinions, how to recognize poor reasoning, and how to analyze information and the reliability of sources. 1.________

Go to the original source. Media reports often simplify the results of medical research. Find out for yourself what a study really reported, and determine whether it was based on good science. Think about the type of study. 2. ________

Watch for misleading language. Some studies will find that a behaviour “contributes to” or is“ associated with” an outcome; this does not mean that a certain course must lead to a certain result. _3._______Carefully read or listen to information in order to fully understand it.

Use your common sense. If a report seems too good to be true, probably it is. Be especially careful of information contained in advertisements. 4.________ Evaluate “scientific” statements carefully, and be aware of quackery(江湖騙術(shù)).

5.________Friends and family members can be a great source of ideas and inspiration, but each of us needs to find a healthy lifestyle that works for us.

Developing the ability to evaluate reasonably and independently about the health problems will serve you well throughout your life.

A. Make choices that are right for you.

B. The goal of an ad is to sell you something.

C. Be sure to work through the critical questions.

D. And examine the findings of the original research.

Eyesight plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:

● Schedule yearly exams. 1. Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

● Protect against UV rays (紫外線). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. 2.

● Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. 3.Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

●4. As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (維生素) C and E help protect eyesight and promote eye health.

● Practice safe wear and care of contact lenses (隱形眼鏡). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. 5. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A. Eat your greens.

B. Eye care should begin early in life.

C. They can properly protect your eyes.

D. Stay in good shape by taking more vitamins.

E. Parents usually don’t care about their own eyesight.

F. Always follow the doctor’s advice for appropriate wear.

G. This frequent eye activity increases the risk for eye tiredness.

科目:高中英語 來源:2016屆寧夏回族自治區(qū)銀川市高三第二次模擬考試英語試卷(解析版) 題型:閱讀理解

Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有機體), which have had specific changes introduced into their DNA by genetic engineering techniques. These techniques are much more precise where an organism is exposed to chemicals to create a non?specific but stable change. For many people, the high?tech production raises all kinds of environmental, ethical, health and safety problems. Particularly in countries with long farming traditions, the idea seems against nature.

In fact, GM foods are already very much a part of our lives. They were first put on the market in 1996. A third of the corn and more than half the cotton grown in the U. S. last year was the product of biotechnology, according to the Department of Agriculture. More than 65 million acres of genetically modified crops will be planted in the US this year. The genetic genie is out of the bottle.

However, like any new product entering the food chain, GM foods must be subjected to careful testing. In wealthy countries, the debate about biotech is not so fierce by the fact that they have a large number of foods to choose from, and a supply that goes beyond the needs. In developing countries desperate to feed fast?growing and underfed populations, the matter is simpler and much more urgent: do the benefits of biotech outweigh the risks?

The statistics on population growth and hunger are disturbing. Last year the world's population reached 6 billion. The UN states that nearly 800 million people around the world are unhealthy. About 400 million women of childbearing age don' t have enough iron, which means their babies are exposed to various birth defeats.As many as 100 million children suffer from vitamin A deficiency, a leading cause of blindness.

How can biotech help? Genetic engineering is widely used to produce plants and animals with better nutritional values. Biotechnologists have developed genetically modified rice and they are working on other kinds of nutritionally improved crops. Biotech can also improve farming productivity in places where food shortages are caused by crop damage attributable to drought, poor soil and crop viruses.

1.The passage mainly talks about________.

A. the world's food problem

B. the development in biotech

C. the genetically modified foods

D. the way to solve food shortages

2.According to the passage, GM foods________.

A. will replace naturally grown foods

B. are far better than naturally grown foods

C. may help to solve the problem of poor nutrition

D. can cause serious trouble in developing countries

3.The underlined sentence “The genetic genie is out of the bottle.” in Paragraph 2 probably means that________.

A. GM foods are available everywhere

B. the technology in producing GM foods is advanced

C. genetic technology may have uncontrollable powers

D. genetic technology has come out of laboratories into markets

4.What's the writer's attitude towards GM foods?

A. Enthusiastic. B. Cautious.

C. Disapproving. D. Unbelievable.
