＝I don't want a car as expensive as this．    我不要这么贵的汽车。 

 Tony is as clever a boy as his brother．  

托尼是一个和他兄弟一样聪明的男孩。 

  五、当as„as与表示重量、数量、时间、距离、价格等的计量名词连用时。往往并不表示比较。而是构成一个形容词组，意为“重达„„，多达„„，高达„„”等。

Most people have flown a kite or have seen one ride and dip(下降) in strong spring wind. Not so many people know that kites were first made in China thousands of years ago. The ancient (古代的) Chinese were making and flying kites even before they were writing.

A long time ago, the Chinese made kites to use in wars. They would fly these war kites in the dark. The kites were fixed (固定) so that they made strange sounds. Men who were at war with them would hear these sounds and run away. They thought those strange sounds were made by gods(神) in the sky.

The ancient Chinese also flew kites to bring good luck and to make their crops（农作物） grow rich and tall. Sometimes they tied long strings (细绳) and hooks (钩) to their kites. Then they would fly the kites over water, letting the hooks hang down to catch fish.

The Chinese use sticks（树枝）, strings（线） and paper for their kites. Some of these kites look like animals or trees. Others look like birds or houses.

We are all busy talking about and using the Internet (因特网), but how many of us know the history of the Internet?

Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks (网络) didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system (系统) had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information（信息）could be sent through another part. In this way computer network system would keep on working all the time.

At first the Internet was only used by the government (政府), but in the early 1970s, universities (大学), hospitals and banks (银行) were allowed (允许) to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software (软件) that made "surfing" (浏览) the Internet more convenient (方便).

Today it is easy to get on-line (上网) and it is said that millions of people use the Internet every day. Sending e-mail (电子邮件) is more and more popular among students.

The Internet has now become one of the most important parts of people's life.
