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.

All the wisdom of the times, all the stories that have delighted mankind for centuries, are easily and cheaply available to all of us in books, but we must know how to make use of this treasure. The unluckiest people in the world are those who have never discovered how satisfying it is to read good books.
I’m very interested in people and finding out about them. Some of the most amazing people I’ve met could only be found in a writer’s imagination, then in his book, and then, again, in my imagination. I’ve found in books new friends and new worlds.
Reading is fun, not because the writer is telling you something, but because it makes your mind work. Your own imagination works along with the writer’s or even goes beyond his. Your experience, compared with his, brings you to the same or different conclusions, and your ideas develop as you understand his.
Every book stands by itself, like a one-family house, but books in a library are like houses in a city. Although they are separate(分开的), in some way they are connected with each other. The same ideas, or related(相关的) ones, appear in different places; the human problems that repeat themselves in life repeat themselves in books, but with different solutions(解决方法) according to different writings at different times. Books influence each other. They connect the past, the present and the future and have their own generations (age groups), like families. Wherever you start reading, you connect yourself with one of the families of ideas, and in the end, you not only find out about the world and the people in it, you find out about yourself, too.
Reading can only be fun if you expect it to be. If you concentrate on(专注于) books somebody tells you “ought” to read, you probably won’ t have fun. But if you put down a book you don’t like and try another till you find one that means something to you, and then relax with it, you will almost certainly have a good time — and if you become, as a result of reading, better, wiser, kinder, or more gentle, you won’t suffer during the process.

Many years before the United States was founded(建立), Americans had already invented barbecues. But the first barbecues, in fact ,were the invention of the Taino Indians of Haiti, who dried their meat on raised frames(架子)of sticks over fires. Spanish explorers spelled the Taino word as barbacoa, and as time passed, English settlers along the Atlantic coat had their own barbecues.
One summer day in 1773, Benjamin Lynde, a citizen of Massachusetts, wrote in his diary, “Fair and hot ; Browne;hack overset.” That is , on a bright and hot day he went to the Brownes to attedn a barbecue, and his carriage(马车)fell over. It shows that the barbecue had its social occasion by that time. Large animals would be roasted whole on frames over hot fires, and neighbours would be invited to dinner.
In later centuries, as settlers moved to the west, the barbecue went along with it, reaching an especially large size in Texas, where a pit (坑)for fuels(燃料) such as tree branches might be over ten feet deep. Today , the barbecue grills(烧烤架)which are fueled by charcoal(木炭) or electricity are likely to be small and easy to move , and can cook only parts of an animal at a time, but people still have barbecues out of doors and always invite their neighbours or friends over.
