Nowadays more and more people are talking about genetically modified foods ( GM foods). GM foods develop from genetically modified organisms (有機(jī)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.

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

Yesterday I started the Year of Giving, my first day of a year-long journey into exploring the act of giving and the meaning of charity. I chose December 15 as the starting date, which marked three years since my mother died from heart disease. She was one of the most generous people that I have ever known. She always thought of others first and certainly serves as an inspiration to me.

I had a rather busy day yesterday, ironic(具有諷刺意義的) for someone who is unemployed right now. In the morning I went to the gym, and unsuccessfully got the phone call from the unemployment office for some job searching. Before I knew it, it was noon. I grabbed a quick lunch and rushed down to a meeting. On my way to Connecticut, I wondered if I would see someone that I would feel forced to give my first $10 to. I was running late and decided to do it afterwards.

After the meeting I had about half an hour to find the first person of my Year of Giving! I decided to check out Dupont Circle. I had met a guy there named Jerry once and thought he would willingly accept my first $10. He wasn’t there, but I did see a man sitting by himself who looked really lonely, so I approached him. Now I had to figure out what I was going to say. I think I said something like, “Hi, can I sit down here?” “I would like to know if I could give you $10?” He asked me to repeat what I had said. I did, then he looked at me funny, got up and left.

I then started walking south where I spotted a man standing by the bus stop on Connecticut Ave. He appeared to be in his 60s. I don’t know what drew me to him, but I thought I would make my second attempt. I was a bit nervous and asked him which bus came by that stop. Then I explained that I was starting a year-long project to give $10 to someone every day and that I wanted to give my $10 for today to him. The gentleman, I later found out that his name was Ed, responded without hesitation that he could not accept my offer and that there were many people more deserving the money than him. This was exactly one of the things that I hoped would happen. People would think of others before themselves!

1. The author set the starting date on December 15 to .

A. help the charity

B. remember his mother

C. make an exploration

D. fulfill a wish of his mum

2. In the author’s first attempt to give away the money， .

A. he was considered ridiculous

B. he hesitated for a long time

C. he was forced to donate the money

D. he had no time to take action

3.In the author’s second attempt, the gentleman refused his offer because .

A. he didn’t need others’ help

B. he thought more for others

C. he didn’t care about money

D. he wanted to get more money

4.We can infer that the author was inspired by .

A. true friendship B. his own kindness

C. generous donations D.human’s good nature
