1.Holly: How I miss the clear water and fresh air in my childhood! But everything has changed, that is, the clear water and fresh air are nowhere to be found again as they were. Above all, a great deal of waste hardly rots(腐烂) away.

2.Jimmy: More and more people are beginning to have a good knowledge of the

importance of a safer and cleaner environment, which in turn forces the business to be cleaned up.

3.Samantha: Organic products(有机产品) are getting more and more popular among people, but we should know the fact that organic products might also do harm to our health in some way.

4.Patria: I’m very much fond of growing some vegetables of my own in my small garden, for many vegetables on sale in markets are actually becoming more and more dangerous as a result of widespread pesticides(农药).

5.Derrick: Nowadays it is very convenient for consumers to find and buy green food in supermarkets as they are clearly marked.

E．Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds．Some supermarket products carry labels(标签) to show that the product is green．Some companies have emphasized it in their advertising that their products are clean and safe enough for people.

F．The concern for a safer and cleaner environment is making companies rethink how they do business．No longer will the public accept the old attitude of "Buy it, use it, throw it away, and forget it." The public pressure is on, and gradually business is cleaning up its act.

Miss Brown would never forget the night when she met a robber(抢劫者) many years ago.

That evening, she went to a birthday party which   1  until two o’clock in the morning. Miss Brown walked in the  2  street alone. Suddenly from the back of the dark building a tall man with a sharp knife in his right hand ran out at her. “Good morning，lady.” the man said in a low voice, “I don’t think you wish to  3 here!” “What do you want?” “Your earrings. Take them  4 !”

Miss Brown suddenly had a   5 idea. She tried to cover her necklace with the collar(衣领)of her overcoat while she used the other hand to take off both of her earrings and then quickly   6 them on the ground.

“Take them and let me go,” she said. The robber thought that the girl didn’t like the earrings at all, only trying to   7 the necklace. The earrings would cost   8 , so he said, “Give me your necklace.”

“Oh, sir. It doesn’t cost much. Please let me wear it.”

“I am not that   9 . Quick!”

With shaking   10  , Miss Brown took off her necklace. As soon as the robber left, she picket up her earrings and ran as fast as she could to one of her friends.

The earrings cost 2000 pounds and the necklace which the robber had taken away cost only six pounds.

Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.

One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.

By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.

Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.

GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.
