If you think that you have to go to the mountains to learn how to climb, you"re wrong. Many Americans are learning to climb in city gyms. Here, people are learning on special climbing walls. The climbing wall goes straight up and has small holding places for hands and feet.      How do people climb the wall? To climb, you need special shoes and a harness (保护带) around your chest to hold you. There are ropes (绳索) tied to your harness. The ropes hold you in place so that you don"t fall. A beginner"s wall is usually about 15 feet high, and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it" s easy to see the new piece of metal. Sometimes, it"s not. The most difficult part is to control your fear. It"s normal (正常的) for humans to be afraid of falling, so it"s difficult not to feel fear. But when you move away from the wall, the harness and the ropes hold you, and you begin to feel safe. You move slowly until you reach the top.       Climbing attracts people because-it"s good exercise for almost everyone. You use your whole body, especially your arms and legs. This sport gives your body a complete workout. When you climb, both your mind and your body can become stronger. 1.

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 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. 1. The Chinese Yellow Sea Wetlands are in the _____ of China. [     ] A. east B. south C. west D. north 2. Usually the weather in the wetlands is _____. [     ] A. hot B. pleasant C. cold D. dry 3. The World Wetlands Day is on _____. [     ] A. April 22 B. June 25 C. February 2 D. March 22 4. We must protect wetlands because _____. [     ] A. they are home for wildlife B. they can prevent flood C. they can offer food to the animals and birds D. all of the above 5. The best title for the passage is _____. [     ] A. China"s Wetlands Have All Entered the World"s List B. Wetlands-Home for Wildlife and Human Beings C. Special Animals in the Chinese Yellow Sea Wetlands D.
