阅读理解综合练习
有些人为了要扩张耕地和工地面积，试图把湿地变成农田，变成建筑，可是这是决不行的!因为湿地对我们人类来说是十分重要的。
There are many wetlands(湿地) in China and some of them have become the worlds 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 worlds 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 Cranes 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(野生生物)。 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 important of wetlands and wildlife. Every year， on February 2nd， many activities are held to tell people more about wetlands.
