It’s about Time

Do you know what time it is? If you do, you probably are looking at a clock or Long ago, people didn’t have clocks or watches like you do. When the sun rose, they got up and when the sun went down, they went to bed. They told timeby the position of the sun in the sky.

People discovered that they could use a stick and the sun to tell time. This was called a shadow clock. They put a stick in the ground, pointing straight up. The direction of the stick’s shadow and how long or shortit was told them the time.

A better kind of shadow clock was called a sundial. Sundial had a pointer and a base. The pointer cast a shadow on marks around the base. People could tell time by reading the marks.

But shadow clocks were not good for telling time on cloudy days or at night.

One kind of clock that didn’t need the sun was a water clock. A water clock was container with a tiny hole in the bottom. Water would steadilydropout of the hole. Marks on the inside of the container showed the time. It took one hour for the water to go down one mark.

Another kind of clock that didn’t need the sun was a candle clock. You would know the time by how much of the candle had melted(熔化). The candle had marks down its side to show the hours.

Sometimes people used candle clocks as alarm clocks. They put a nail(钉子)in the candle at the time they wanted to wake up, hanging a shoe on the nail. When the candle melted down, the nail fell outand the shoe hit the floor with a BANG! Now there are all kinds of timepieces, from tall grandfather clocks to watches we wear on our wrists(手腕). Most clocks run on electricity from batteries.

There are many more types of clocks, too. Clocks hang in and on buildings. Clocks are everywhere!

5.What does the writer want to tell us?

1979 was World Conservation(自然保护)Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would go into action(采取行动)quickly in order to conserve nature. Here is one example of the problems. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology(技术). We are changing the earth, the air and the water, and everything that grows and lives. We can’t live without these plants. If we continue like this, we will 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 in 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 kilometers of their river. Young people may hear about conversation through a record called “No one’s going to change our world.” It was made by the Beatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.
