Today there are 6.4 billion people on the earth. By the year 2050 there may be 12.5 billion . There are a lot of people to feed. We need more  and more food.

     One way to produce more food is 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(遗传的) material. Foods from plants grown in this way are called genetically modified(改变的) foods, 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 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 interested in their use, and they are not going to go away. In 2050, we may think differently about them.

Once there was an island where all the feelings lived: Happiness, Sadness, Knowledge, and all of the others, including Love. One day it was said that the island would go down, so all made boats and left except Love.

Love was the only one who stayed. Love wanted to offer her help until the last possible moment. When the island had almost gone down, Love decided to ask for help.

Richness was passing by Love in a great boat. Love said, “Richness, can you take me with you?” Richness answered, “No, I can’t. There is a lot of gold and silver in my boat. There is no place here for you.”

Sadness was close by, so Love asked, “Sadness, let me go with you .” “Oh, Love, I am so sad that I need to be by myself!”

Happiness passed by Love, too, but she was so happy that she did not even notice when Love called her.

Suddenly, there was a voice, “Come, Love, I will take you.” It was an elder. Love was so excited that she even forgot to ask who the elder was. So Love asked Knowledge, another elder, “Who helped me?” “It was Time,” Knowledge answered. “Time?” asked Love. “But why did Time help me?”

“ Cool ” is a word with many meanings. Its old meaning is used to express a temperature that is a little bit cold. As the world has changed, the word has had many different meanings.

“ Cool ” can be used to express feelings of interest in almost anything.

When you see a famous car in the street, maybe you will say, “It’s cool . ” You may think, “He’s so cool,”when you see your favourite footballer.

We all maximize(扩大)the meaning of “cool”. You can use it instead of many words such as “ new ”or “ surprising ”. Here’s an interesting story we can use to show the way the word is used.
