     If you are near-sighted and need to wear glasses all the time, you have to go to astore or hospital to
have your lenses (镜片)  changed from time to time.  John Silver, a professor at Oxford University, may
be able to help you.
   He has invented a pair of glasses that the wearers can change the lenses themselves. The glasses are
based on a simple principle: the fatter the lens is, the more powerful it is.  Inside each lens is a clear bag
filled with fluid (液体).  The wearers can change the amount of fluid with a syringe to change the power
of the lenses.
      The invention may be a great help to near-sighted people in the' developing world. In the UK, there
is one optometrist (验光师) for every 4,soo people, but in Africa only one for every l,000,000.
    So far, professor Silver has made30,000 pairs of glasses, and has given them away to 15 countries.
He plans to offer them to a billion people in the world's poorest areas by 2020.

(     )1. John Silver is an optometrist.
(     )2. The word "principle" means "原理".
(     )3. To make the new glasses more powerful, less fluid should be put into the bags in the lenses.
(     )4. This kind of glasses will be useful in Africa because it's hard to find an optometrist there.
(     )5. The passage mainly tell us about a famous inventor.

There are many wetlands (湿地) in China and some of them have become the world's important wetlands.

The Chinese Yellow Sea Wetlands are among them. They are in Yancheng, Jiangsu Province. They are home for many different kinds of birds and animals. The world's largest Milu Deer Nature Reserve (自然保护区) is in them. More than 700 Milu deer live freely there. There are not many red-Crowned cranes in the world, but every winter you can see some in the red-Crowned Nature Reserve in the Yellow Sea Wetlands.

The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine, too. They are really good places for wildlife (野生动物). Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands. Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.

Luckily, more and more people are beginning to realize the importance of wetlands and wildlife. Every year, on February 2nd, many activities are held to tell people more about wetlands.

1.The Chinese Yellow Sea Wetlands are in the west of China.

2.Usually the weather in the wetlands is pleasant.

3.February 2nd is the world's wetlands Day.

4.We must protect wetlands only because they can offer food to the animals and birds.

5.Wetlands are valuable resources of land on the earth.

Do you live in a city? Do you know how cities began? Long long ago, the world had only a few thousand people. These people moved from one place to another. They moved over the land, hunting animals for food.

No one knows how or when these people learned about growing food. But when they did， their lives changed. They did not have to look for food any longer. They could stay in one place and grow it. People began to live near one another, so the first village was established. Many people came to work in the villages, and these villages became even larger.

When machines appeared, life in the villages changed again. People built factories. More and more people lived near the factories. The cities began.

Today, it’s strange that some people are moving back to small villages. Can you tell me why?
