The first computer was made in 1946. It was very big but it worked slowly. Today computers are getting smaller and smaller. But they work faster and faster. What can computers do? A writer has said. “People can’t live without computers today.”

The Internet came a little later than computers. It is about twenty-five years later than computers. But now it can be found almost everywhere. We can use it to read books, write letters, do shopping, play games or make friends.

Many students like the Internet very much. They often go into the Internet as soon as they are free. They make friends on the Internet and maybe they have never seen these friends. They don’t know their real names, ages, and even sex. They are so interested in making the “unreal friends” that they can’t put their hearts into study. Many of them can’t catch up with others on many subjects because of that.

We can use computers and the Internet to learn more about the world. But at the same time, we should remember that not all the things can be done by computers and the Internet.

【推荐1】How often do you leave food on your plate? Does your family throw food from the fridge because it’s no longer fresh?     1    

About one third of all food in the world is wasted (浪费). Among the waste, 45% of fruits and vegetables, 35% of seafood, and 30% of cereal (谷类食物) are wasted.     2    

Food waste is a big problem. It costs money and hurts the environment.

    3     One good way is to add it to the soil(土壤) to help plants grow. Much of food waste can help improve the soil in our gardens if we use it correctly. (So food waste can be useful and we should get more people to understand its value.)

    4     We should take time to think about how much food we will actually eat. Another way is to join organizations that give food to people that don’t have enough food. Finally, give uneaten food to pets or farm animals.     5     However, if we all make an effort, we can make a difference.

【推荐2】Happiness is important in our life. It can make us energetic(充满活力的). Are you happy? Do you want to be happy every day?     1    

Be confidence(自信的). Every morning after you get up and look at yourself in the mirror, what will you do?     2     Don’t always think that you are not as good as others. You can be the best in the world.

Smile. When you have problems, what will you do? Are you unhappy because of the problems?     3     Smile at yourself, and keep on smiling.

Talk to others. Being alone nice. You should talk to your friends or your family.     4     Open your heart to the worry, and you will find the world is more colorful than you think.

All in all, it is not hard to be happy     5     Remember to be confident, to smile all the time and to talk with others .Wish you a happy life.

【推荐2】A team of scientists are carrying out a project at the University of Greenwich in London. They are trying to find ways to make food on Mars (火星) in the future. The project is called “Feeding Mars”. It tries to use water, fish and fish waste to grow fruit and vegetables on Mars.

It would take at least 21 months to reach Mars, learn about its surface (表面) and return to Earth. So it would be a big help if the spacemen could grow fresh food on Mars itself.

Farming on Mars, however, will be very hard. There’s plenty of water that could be taken from ice just below the surface, but the land on Mars is missing the nutrients (养分) that living things need. The team say they could solve the problem by growing plants and fish together. Fish waste can then be used to provide nutrients for plants.

“It is expected that you can grow lots of food, such as vegetables, salads, teas and medicinal plants on Mars,” said Dr. Baboon, who leads the project. “You can even harvest (捕获) fish for food then.”
