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 (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 (生物多樣性) of our earth.

Wilson begins with an open letter to the pioneer in environment (環(huán)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.

Answer 1

解析;細(xì)節(jié)理解題。根據(jù)全文描述可知，Wilson在其著作The Future of Life中非常關(guān)注生物的多樣性。只是簡(jiǎn)單提到植物的生存環(huán)境，自然資源的浪費(fèi)以及人類價(jià)值觀的重要性。

答案;B

解析;細(xì)節(jié)理解題。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，近一百種物種是人們基本的食物 ，然而主要依賴其中的大約二十種。carry the load意為“挑擔(dān)子”。

答案;A

解析;細(xì)節(jié)理解題。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...”，可以看出使用更多種類的物種作為食物，是保持或促進(jìn)物種多樣性的方法。

答案;D

解析;推理判斷題。通觀全文可以看出，作者的寫作目的是介紹Wilson的The Future of Life一書，是一篇書評(píng)。

答案;C
