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 what 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 . However, it isn’t a kind of food additive. The food made from Sudan red makes it easier to cause cancer. Melamine(三聚氰胺) is another kind of chemical that are banned(禁止). It’s white crystal(晶体), which was discovered by a German chemist called Sustus Von Liebig in 1834. Melamine can be used to make paper, medicine and woods, ect. But nobody can imagine that some people used it as a material of milk powder(粉末). Because of melamine, it’s reported that 4 babies died and more than 50 thousand babies are affected since 2008. Sanlu, a famous milk powder factory was closed. What’s worse, milk powder with melamine appeared in 2011 again. Problems of food safety, for example, poisonous rice, lean meat powder(瘦肉精) and plasticizers(塑化剂) are becoming more and more serious.
Fortunately, lots of laws have been made to make the solution(解决方法) better. We think we will eat more healthily in the future.

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.

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.

The first No Car Day in China was in Chengdu in 2001. Other cities including Taipei, Shanghai and Wuhan, also support the day.
In Beijing, more and more people are taking part in the activity. It asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. It also calls on Beijingers not to use cars on June 5th (World Environment Day). The slogan(口号) for the day is, “ If we drive for one less day, we can have one more nice day.”
So far, more than 200,000 drivers have shown their support. “We can’t control the weather, but we can choose not to drive,” said Wu Zhonghua, a car club chairman.
