二、阅读理解-阅读回答问题（共1小题；）
Cloud Forests
In the Americas, Asia, and Africa, there's a special kind of forest—the cloud forest. Cloud forests are usually found from 500 meters to 4,000 meters above sea level in the clouds on the slopes (斜坡) of mountains. They experience rainfall, but they also get water straight from the air. The water is unpolluted, and moves through the ground into streams and then rivers.
Cloud forests are very important to both people who live nearby and the animals and plants living there. They provide water to nearby villages and cities. People drink the water, use it for cooking, and irrigate (灌溉) their farm fields with it. In Kenya, people even use water from cloud forests to produce electricity. Although cloud forests only make up 2.5 percent of the world's rainforests, they are also home to many animals and plants.
Unfortunately cloud forests now face many problems. Local poor people clear the cloud forests. They cut down trees to grow food and use the wood to heat their homes and cook. Building roads also badly harms the cloud forests. Once cloud forests are cleared, the cloud cover which is important and necessary to the growth of these forests, goes away. Another bigger worry is that the temperature increases gradually. If world temperatures rise, cloud forests will have to move up to a higher place where the temperatures are cooler. But some cloud forests on mountain tops with nowhere to climb will die out.
Scientists fear we might lose cloud forests along with the water and other services they provide. Some governments have taken actions to protect cloud forests. They make laws against cutting down trees in the cloud forests. They provide the local people with other ways to get food and energy. They also educate the local people on how cloud forests provide fresh water and what will happen when they are cleared.
Cloud forests are too valuable to lose. We must save them—plus the animals and plants they support—before it's too late.
