Brazilian scientists think they might have found a way to reverse the damage caused by deforestation and turn farmland back into forest. The secret lies in ancient local knowledge of soil. Amazonian dark earth (ADE) is a thick， black soil found deep in the Amazon rainforest， and it could help restore forests around the world. ADE is a kind of compost — a soil made from dead plants and animals. Various kinds of compost are sold in gardening centers around the world， but ADE is unique. It was created by indigenous people (the descendants of people who lived somewhere before another culture arrived and took over) from the Amazon between 2，000 and 2，500 years ago. The Amazonian people， today known as Amerindians， created ADE using charcoal from fires， animal bones， food waste and poo. It contains microbes， including bacteria that help to turn chemicals in the soil into useful nutrients that feed plants and trees. Vast areas of the Amazon have been cut down， mostly to make way for grassland for raising cattle. Scientists are looking for a way to turn grassland back into rainforest and revive forest ecosystems. These support thousands of animal and plant species， many of them unique to the area. Forests also absorb lots of carbon dioxide， a gas that causes climate change. To see if the Amazon's special soil could help， the scientists grew grasses and trees in ADE， regular earth and a mixture of both. Trees grown in ADE were up to six times taller than those in regular soil. ADE takes hundreds of years to create， so the scientists can't simply make more. Team member， Dr. Siu Mui Tsai， said that instead they want to try and “copy its characteristics”， especially its helpful microbes， and see if it could help to restore natural habitats. 语篇解读：本文是一篇说明文。巴西科学家发现当地亚马孙雨林中的黑土可能会帮助人们恢复森林生态系统，这种黑土富含有益的微生物，有助于土壤中成分的转化，帮助植物的生长，但这种黑土形成所需的时间较长，因此科学家只能通过复制其特征来尝试恢复自然栖息地。 1．What are Brazilian scientists trying to do？ A．To bring forests back.
