Some people even go to the rain forests to spend some of their time trying to make friends with the plants and animals there. The scientists are actually hard at work studying the plants that grow in the very top level of a rain forest. Rain forests are one of the richest environments on Earth. They are home to millions of species of plants and animals. The red research raft provides scientists with a platform from which to study life in the treetops. Scientists can even sleep on the raft, so they can stay up in the treetops for days at a time. Rain forests cover only about 6 percent of Earth39。s land surface. However, they contain more than half of the plant species on Earth. Many of these plants provide useful medicines to use against human diseases. In fact, about 25 percent of prescription medicines in the United States are based on chemicals from rain forest plants. Scientists think that many new medicines might be developed from plants that are yet to be discovered. Unluckily, rain forests are disappearing. Rain forest trees are being cut down for wood. Huge chunks of the forests are cleared to provide land for farm animals and crops. Scientists haven39。t identified all the plants in these forests yet. Some scientists think thousands of kinds of plants that we39。ll never even know about are being destroyed each year. 根據短文內容，完成下列小題。 76. Is it difficult for scientists to study the rain forest plants? 77. Where probably is the red research raft? 78. How much of Earth39。s land surface do rain forests cover? 79.
