What do you think are the most important inventions of the past 2,000 years? The TV? The printing? The telephone? Or the computer? A report shows that these are not the only important inventions. Here are four other important ones.

Paper is one of the most important inventions. You can’t have printing without paper. In 105 AD, Cai Lun invented paper in China. Long before the printing and Internet, Cai Lun’s invention allowed us to write down information, stories and history.

One of the simplest (最简单) inventions to save life is the toilet. Before toilets, waste ran into the rivers from people’s houses. Illnesses were common (普通的) in big cities, and it was often difficult to find clean drinking water.

Animal food is another invention. Before the invention, most animals were killed every autumn because there was not enough food for them in the winter. After hay (干草) became a kind of common animal food, animals could live through the long winter.

Reading glasses is the fourth invention. People start getting far-sighted (远视) from the age of 45. Glasses mean that anyone can read, write and do “close work” after that age. Without glasses, the world would be difficult for the people above 45.

1.Cai Lun’s invention of paper makes it possible to ______.

A．have printing                           B．feed animals

C．drink clean water                       D．do “close work”

2.The invention of the toilet can stop people from ______.

A．saving water                           B．getting ill

A．It was very cold in winter.                 B．They didn’t have enough food to eat.

C．They had no drinking water.               D．They died of illness.

4.From the last paragraph we learn that ______.

A．all people need reading glasses

B．anyone must do “close work” after 45

C．reading glasses are useful

D．life is more difficult for the people under 45

Today almost everyone knows computers and the Internet. If I ask you “What is the most important thing in your life?”, maybe you will say “Computers and the Internet”.

     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, send e-mails, do some shopping, play games or make friends.             

     Young men, especially the middle school students like the Internet very much. They often go into the Internet bars 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 names, ages and sex(性别). They are so interested in making the “unreal friends” that they can’t put their heart into study. Some of them play the games in the Internet bars all day and all night. Many of them can’t catch up with others in many subjects because of that.

      Now the government has done many things. Some gangster Internet bars(黑网吧)have been banned(取缔). But that’s not enough. The teachers and parents are still worrying about their students and children.

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