Question

Edward Wilson is America's, if not the world's, leading naturalist. In The Future of Life, he takes us on a tour of the world's natural resources (资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity (生物多样性) of our earth.

Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today's Walden Pond with that of Thoreau's day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Can the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?

Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species (物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.

At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book.

Answer 1

解析;细节理解题。根据全文描述可知，Wilson在其著作The Future of Life中非常关注生物的多样性。只是简单提到植物的生存环境，自然资源的浪费以及人类价值观的重要性。

答案;B

解析;细节理解题。文章第三段“A mere hundred species are the basis of our food supply，of which but twenty carry the load.”指出，近一百种物种是人们基本的食物 ，然而主要依赖其中的大约二十种。carry the load意为“挑担子”。

答案;A

解析;细节理解题。文章第三段提到“Wilson suggests changing this situation by looking into ten thousand species that could be made use of，which will be a way to reduce the clearing of the natural homes of...”，可以看出使用更多种类的物种作为食物，是保持或促进物种多样性的方法。
