Today there are 6 billion people on the earth．By the year 2050 there may be 12.5 billion．This means 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 food 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．
1970 was the “ Would Conservation Year ”．The United Nations wanted everyone to know that the world was in danger．They hoped that governments would act quickly in order to conserve(保护)nature．Here is one example of the problem．At one time there was 1300 different kinds of plants, trees and flowers in Holand , but now only 866 remain．The others have been destroyed by modern man and his technology．We are changing the earth．the air and the water, and everything that grows and lives here．We can’t live without these things．If things continue like this , we shall destroy ourselves．
What will happen in the future?Perhaps it is more important to ask , “What must we do now?” The people who will be living ing the world of tomorrow are the young of today．A lot of them know that conservation is necessary．Many are helping to save our world．They plant trees , build bridges across rivers in forests and so on．In a small town in the United States , a large group of girls cleaned the banks of 11 kilometes of their river．Young people may hear about conservation through a record called NO ONE’S GOING TO CHANGE OUR WORLD．It was made by the Beatles and other singers．The money from it will help to conserve animals．

Hundreds of years ago, life was much harder than it is today．People didn’t have modern machines．There was no modern medicine, either．
Life today has brought new problems．One of the biggest is pollution(污染)．Water pollution has made our rivers and lakes dirty．It kills our fish and polluted our drinking water．Noise pollution makes us talk louder and become angry more easily．Air pollution is the most serious kind of pollution．It’s bad to all living things in the world．
Cars, planes and factories all pollute our air every day．Sometimes the polluted air is so thick that it is like a quilt over a city．This kind of quilt is called smog(烟雾)．
Many countries are making rules to fight pollution．Factories must now clean their water before it is thrown away, they mustn’t blow dirty smoke into the air．
We need to do many other things．We can put waste things in the dustbin and not throw it on the ground．We can go to work by bus or with our friends in the same car．If there are fewer people driving, there will be less pollution．
Rules are not enough．Every person must help to fight pollution．

Tea bag drinking is most Westerns’ favorite way of drinking tea．Do you know how it came about?
The tea bag was invented in 1908 by Thomas Sullivan, an American tea seller．He was sending out free tea in silk(丝绸)bags for people to try．People put the bags together with the tea leaves into the cup and added hot water．The tea tasted good, and people thought it was easy to clean the cup．They were not happy when Sullivan started sending them loose(散的)tea again．
Sullivan realized that he had a hot new thing in his hands, and he built a machine to pack the bags．As tea bags became popular, they were changed from silk to gauze(薄纱)and later paper．In 1952, Lipton Tea made the tea bag even more popular with its invention of the four-sided tea bag．Tea bags were soon a hit in the UK, and today 85％ of the tea in the UK is packed in paper bags．

As a Manchester United player, David Beckham is used to winning．He is one of the most famous Englishmen in the World today．
Of course, it is impossible to have an unbiased opinion of this young man or the team that he plays for．If you are a Man United fan, you love him．If you aren't a fan of this team, then your opinion of Mr．Beckham may be quite different．In fact, in recent times, his treatment by fans of other teams has been extremely unsavory, especially when he has been playing for England．Some of the worst words have not even been aimed at Beckham but at his wife and young child, which is a bad thing．It has been hard for the football leaders to control such unruly behavior．How can you discipline people for their comments when so many people are guilty? But under the pressure of being shouted at by so many people, he has always remained calm．
Of course, a lot of the bad things about Beckham are due to his own actions．He is a very fashionable young man, but some of the clothes he has worn have been simply amazing．Why a person in his position would choose to wear a skirt in public is truly unbelievable! Furthermore, to wear such things in unseasonable times as mid-winter seems even crazier!
His behavior on the football pitch has also been unpredictable at times．Sometimes he is brilliant; sometimes he does crazy things．Some of the most famous footballing incidents involving Beckham are not his spectacular goals but his ungainly tackles．The most famous occasion was in France'98, when a clumsy tackle led to him being sent off．
However, he is not guilty of such things, and if he can stop such behavior he could even become England's next captain．
