第六组(共2篇):
(A )
A man once had a dream about the Black Forest in Germany. In his dream he was walking in the forest when two men ran out and tried to throw him to the ground. He ran off as fast as he could, but they followed him. He reached a place where he saw two roads in front of him, one to the right and the other to the left. Which road should he take? He heard the two men behind him, getting nearer, and at the same time he heard a voice in his ear. It told him to go to the right, and he did so. He ran on and soon came to a small hotel. He was received there kindly and given a room, and he was saved from the two men. That was the dream.
Twenty years later he was really in the Black Forest and, as happened in the dream long ago, two men ran out and tried to throw him down. He ran off, and came to a place with two roads, like in the dream. He remembered the dream and took the road to the right. He soon reached a small hotel, was taken in, and so was safe. His dream of twenty years before had saved his life.

B. Water shortage is the only problem in our world.

(C)
Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. This is 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 (准备), 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.
