阅读理解。 Wetlands! Valuable Resources on the Earth There are many wetlands 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 animals. The world's largest Milu Deer Nature Reserve 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 Crane Nature Reserve in the Yellow Sea Wetlands. The temperature in the wetlands is usually neither too high nor too low. There us a lot of rain and sunshine, too. They are really good places for wildlife. Offering (提供) food and home for some special kinds of animals 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 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 ______ of China. [     ] A. east B. south C. west D. north 2.
