Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely paid no.

“We don’t know whether the food is safe,” said Zambia’s commerce, Trade and Industry Minister Dipak Patel.

His worries are shared by countries around the world that are in two minds about America’s genetically modified（GM）crops. Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US.

Ever since people started farming, they have tried to crossbreed（杂交） plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other.

But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature.

This means they can make crops more productive and resistant to disease by adding genes from other species. They can also create food with special characteristics, such as “golden rice”, which is enriched with vitamin A. But many people believe GM foods are a health risk.

“If left to me, I would certainly not eat GM foods,” said Scottish scientist Arpad Pusztai. “We are putting new things into food which haven’t been eaten before. The effects on the immune system are not easy to predict.”

At the moment, the official argument is that GM foods “are not likely to present risks for human health”. But there are still many questions to be answered as the foods are produced in different ways.

Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops.

In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful (有压力的) events. They found out that any major change can be stressful. Negative events like "serious illness of a family member" were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress--it only shows how much you have to deal with. And we now know that the way you deal with these events has a great effect on your chances of staying healthy.

     By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like "Stress causes illness! "If you want to stay physically and mentally healthy,” the articles said, “avoid stressful events.” But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many--- like the death of a loved one---are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription (处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move.

     The idea that all stress makes you sick also takes no notice of what we know about people. It is supposed that we're all weak and passive in the face of difficulty.  But many come through periods of stress with more physical and mental strength than they had before.  We also know that a long time without change or challenge can lead to boredom, and physical and mental damage.

Martha had been working for Miller Laboratories for two years, but she was not happy there. Nothing significant had happened in the way of promotions or salary increases. Martha felt that her supervisor, a younger and less experienced person than she, did not like her. In fact, the supervisor often said unpleasant things to her.

    One day, while talking with her friend Maria, she mentioned how discouraged she was. Maria gave her the name of a cousin of hers who was director of Human Resources Department for a large chemical company. Martha called him the next day and set up an interview on her lunch hour.

    During the interview, Mr. Petri said, “You’re just the kind of person we need here. You’re being wasted in your other job. Give me a call in a day or two. I’m sure we can find a place for you in our organization.” Martha was so happy she almost danced out of the building.

    That afternoon, Ruth Kenny, her supervisor, saw that Martha had come in ten minutes late from her lunch hour and she said, “Oh, so you finally decided to come back to work today?”

    This was the last straw. She could not take another insult. Besides, Mr. Petri was right: she was being wasted in this job.

    “Look,” she said angrily, “if you don’t like the way I work, I don’t need to stay here. I’ll go where I’m appreciated! Good-bye!” She took up her things and stormed out of the office.

    That night she called Maria and told her what had happened and then asked Maria, “What do you think?”

    “Well,” said Maria carefully, “Are you sure about the other job?”

    “Well, not exactly, but…”

    Maria continued, “Will you be able to get a recommendation from Ms. Kenny if you need one?”

    “A recommendation from Ms. Kenny?” hesitated Martha, in a worried tone.

    “Martha, I hope you didn’t burn your bridges,” Maria said. “I think I would have handled it differently.”
