China is doing a great job of"greening"the world. A team of scientists at Boston University have been working to study Earth's green vegetation () They found that leaf area had increased by 5% since the early 2000s.And according to the study, China was responsible for 25%of that gain )That's about one-quarter of the size of the Amazon rainforest. The growth mainly came from China's forest protection projects.For example,since 1962,Chi- na has been planting trees in Saihanba,Hebei Province.It was once a desert.But now,it is country's largest man-made forest. The Chinese public has also joined in these activities.Ant Forest is one of public projects to give users points for doing eco-friendly(环保) things.Users can use these points to water and grow their own virtual(虚拟的)trees..When the virtual trees are big enough,Ant Forest will plant real trees somewhere in the world.More than 55 million trees have been planted in this way. 阅读以上短文，根据其内容判读下列句子正 误（正确填A,错误填B)。 ()1.To stop global warming,planting trees is the only thing to do. ()2.Scientists at Boston University found that China has greatly increased the amount Unit 8 94 (数量)of green vegetation.
