Ⅳ.阅读理解

It is widely believed  that biodiversity（生物多样性）is promoted to save species. But in reality species exist only as part of ecosystems and cannot survive unless their ecosystems are protected along with as much as possible of the diversity they contain.

　　Protecting habitats（栖息地）is important for keeping biodiversity. In 2003，over 102，000  habitats covering nearly 19 million square kilometres，or 11. 5 % of the world’s land surface， were under some form of protection. Though this is a great improvement since 1962，when just  l，000 protected habitats were listed，it is still not considered enough to stop the ecocide that is endangering the world’s biodiversity.

　　For a number of environmentalists，protecting the world’s 25 biodiversity hot spots（热点地区）is critical to saving habitats and species. But many hot spots are endangered already，having lost up to three quarters of their original plants.

　　The poor state of most biodiversity hot spots results directly from population growth and migration（迁移）into these areas. A study found that by the mid-1990s around one billion people lived in these hot spots. Moreover，the  annual population growth rate in these areas was l. 8%，higher than the global average of l. 4%.  The PAI report concluded that human-related environmental changes will continue to put pressure on hot spots. Therefore，keeping biodiversity  requires paying close attention to population size.

　　Protecting hot spots is not simply a matter of putting up fences and employing guards. The best results are achieved when local people are educated about the value of wildlife，and actually gain a share of the benefits from ecotourism. Only then do they have a chance to see the benefits of protecting hot spots.

1. What can we infer from Paragraph l?

A. The loss of any species can affect humans.

B. Endangered species are paid more attention to by humans.

C. Species can still survive when their ecosystems  are destroyed.

D. Ecosystem protection is as important as diversity protection.

2. What does the underlined word“ecocide”in Paragraph 2 mean?

A. Ecosystem protection.   B. Reduction of the number of species.

C. Serious damage to habitats.  D. Habitats protection.

3. What’s the direct cause of the terrible state of the hot spots?

A. Population growth in hot spots.  B. Migration out of these areas.

C. Global warming.   D. The global average population growth rate.

4. What’s the author’s opinion on protecting hot spots?

A. It’s simple to carry out.   B. It leads to the increase in tourists.

C. It’s closely connected with local people. D. It suggests that the local people are well educated.

Ⅳ.【语篇解读】这是一篇说明文。文章主要介绍了保护世界生物多样性，不仅要保护物种，更要关注热点地区的保护。

1. D　推理判断题。根据文章第一段中的“But in reality species exist only as part of ecosystems and cannot survive unless their ecosystems are protected along with as much as possible of the diversity they contain.”可知，生态系统保护与多样性保护同样重要。

2. C　词义猜测题。根据文章第二段中画线词所在句的Though this is a great improvement since 1962，when just l，000 protected habitats were listed和is endangering the world’s biodiversity可知，虽然保护栖息地力度增加，但仍然不足以阻止危及世界生物多样性的生态破坏。所以ecocide 为“生态破坏”之意。

3. A　细节理解题。根据文章第四段的“The poor state of most biodiversity hot spots results directly from population growth and migration into these areas.”可知，造成热点地区糟糕状况的直接原因是人口增长。

4. C　推理判断题。根据文章最后一段的“The best results are achieved when local people are educated about the value of wildlife，and actually gain a share of the benefits from eco-tourism. Only then do they have a chance to see the benefits of protecting hot spots.”可推断，作者的观点是保护热点地区与当地人密切相关。
