 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*)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. Van 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.

【回答】

72. B【试题解析】推理判断题.文章第一段Edward Wilson的书The Future of Life不仅让我们对资源的来龙去脉有一个很好地了解,而且指出“我们有必要对地球的生物多样*有一个充分的了解。”第三段的语句Biodiversity, Wilson argues, is the key to settling many problems the earth faces today.也说明了Biodiversity是解决地球面临许多问题的关键。故选B项。

73. A【试题解析】从文章第三段的语句A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load.对我们的事物供给的物种最重要的有20种。

74. D【试题解析】从文章第三段的语句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.可知Wilson建议保持地球生物多样*的方法之一就是寻求更多的可以利用的物种。

75. C【试题解析】从文章开头的In The Future of Life, he takes us on a tour of the world’s natural resources(资源).到结尾处的At the end of the book, Wilson discusses the importance of human values…可知该文是介绍一本书的内容。
