問題詳情：

 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(資源). 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(生物多樣*)of our earth.

    Wilson begins with an open letter to the pioneer in environment (環境) 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(物種) 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.

A. the environment for plants                    B. the biodiversity of our earth

【回答】

72. B【試題解析】推理判斷題.文章第一段Edward Wilson的書The Future of Life不僅讓我們對資源的來龍去脈有一個很好地瞭解,而且指出“我們有必要對地球的生物多樣*有一個充分的瞭解。”第三段的語句Biodiversity, Wilson argues, is the key to settling many problems the earth faces today.也說明了Biodiversity是解決地球面臨許多問題的關鍵。故選B項。

73. A【試題解析】從文章第三段的語句A mere hundred species(物種) are the basis of our food supply, of which but twenty carry the load.對我們的事物供給的物種最重要的有20種。

74. D【試題解析】從文章第三段的語句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建議保持地球生物多樣*的方法之一就是尋求更多的可以利用的物種。

75. C【試題解析】從文章開頭的In The Future of Life, he takes us on a tour of the world’s natural resources(資源).到結尾處的At the end of the book, Wilson discusses the importance of human values…可知該文是介紹一本書的內容。
