【正确答案】 B

【答案解析】[听力原文] Life as we know it would simply not exist without plants. Biodiversity—the web of all life on Earth—depends fundamentally on plants and fungi. Plants are used by every human being on the planet, every single day. Just think of what you ate for breakfast this morning, the cup of coffee at your desk, the clothes you're wearing. Plants provide the human race with food, fuel, medicine, clothing and shelter, whether we live in the countryside or a modem city, in Europe or in sub-Saharan Africa. Plants provide invaluable services, they provide us with the very air we breathe, clean water and fertile soil and they help regulate the climate. Plants also provide habitats and food for mammals, birds and invertebrates around the globe. But we are living in an age of acute plant blindness. Somehow, while we make great strides in technology, many of us have forgotten the fundamental importance of the very things on which our lives ultimately depend. Plant diversity is being destroyed at a greater rate than ever before and much of this is due to habitat loss through changes in land use. We believe that economic development must go hand in hand with care for the environment. At the Royal Botanic Gardens, Kew, and other botanic gardens around the world, our plant scientists and horticulturists are working towards effective, science-based conservation solutions to ensure that we leave a healthy and hopeful world to the next generation. What does biodiversity depend mainly on, according to the passage? 本题问生物多样性的基础是什么。文章开头提到，生物多样性主要依赖于植物和真菌。故本题选B。

【正确答案】 D

【答案解析】[听力原文] What does the phrase 'plant blindness' refer to? 本题是细节题，问的是文中的plant blindness指的是什么。文中提到，植物是人类生存和生活的基础，然而随着科技的进步，很多人遗忘了植物的重要意义和作用，植物的多样性正由于人类的各种活动而遭到前所未有的破坏。四项巾，只有D项与这一意思一致，故为正确答案。

【正确答案】 C

【答案解析】[听力原文] In order to leave a healthy and hopeful world to the next generation, what do we have to do? 题目问的是为了给我们的下一代留下一个健康而充满希望的世界，我们应该怎么做。文中提到，经济发展必须和环境保护相结合，目前，世界上的植物科学家和园艺师正携手研究更有效和科学的环境保护方法，以确保给我们的下一代留下一个健康而充满希望的世界，故本题选C。
