Recently, more and more people pay attention to eating healthily. Some food additives(添加剂) are used to make different kinds of foods. Some of them can make the food more delicious and some of them can make it colorful. But lots of chemicals are used to produce wha
t we eat every day.Sudan red is a kind of chemical that factories used it to dye cloth, make the shoes brighter. But some people produced salted duck eggs with it .

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.
小题1:GM foods are made by
A. farmers B. workers C. scientists D plants
小题2:What are the good things about GM foods ?

小题4:Why do some people not like GM foods?

C. They are not natural. D They are not cheap.
小题5:From the passage we know that .
| A．GM foods will disappear one day in the future |
| B．GM foods will not disappear in the future |
| C．People will not be interested in GM foods. |
| D．People will have to stop using GM foods |
小题1:How many times at least should we brush our teeth a day?

| A．Only brush front teeth. |
| B．Don’t brush teeth before sleeping. |
| C．Spend at most three minutes brushing teeth each time. |
| D．Eat lots of fruit and vegetables and drink water instead of soda. |
What will happen in the future? Perhaps 20 is more important to ask “What must we do now?” The people who will be living in the world tomorrow are 21 young of today. A lot of them know that conservation is necessary. Many are helping to save 22 .
Now fifteen million young people in many countries are studying 23 and the country around him. In some countries they spend much time as “conservation volunteers.” They plant trees and help to 24 wild birds and animals.
But everyone, 25 young people, must work to save our world.
