Question

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.

Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.

“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.

The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.

“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近親交配) problems ... and at the end these species may disappear,” he added.

Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.

The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.

Other consequences could include the spread of invasive species and infectious diseases, it said.

The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(紅樹林), inland waters, forests, savannahs(非洲大草原) and grasslands.

The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.

The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.

It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

1.What does the author tell us in Paragraph 2?

A．The theme of global climate negotiations in Durban.

B．The subject of research done by Eduardo Rojas.

C．Causes of damage done to ecosystems.

D．Harmful effects of damage done to ecosystems.

2.Why are animals living in mountains, islands and coastal areas most affected?

A．They are frequently attacked by invasive species and infectious diseases.

B．They have difficulty finding enough food for survival.

C．They can hardly find mates to produce their young.

D．They have little chance of moving to other places.

3.To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT ______.

A．restoring damaged ecosystems

B．limiting world population growth

C．creating movement channels for animals

D．urging governments and local communities to take action

4.What does the underlined word “mitigate” in the last paragraph mean?

A．increase or further improve something.

B．Make full use of something.

C．Make something become less serious.

D．Move from one place to another.

5.What would serve as the best title for the passage?

A．Animals at risk due to climate change.

B．Global warming and its consequences.

C．Climate change and ecotourism.

D．Solutions to animal distinction.

【解析】

試題分析：本文主要講述的是全球氣候的變化對(duì)野生動(dòng)物的影響，文章中舉了很多具體的例子來進(jìn)行詳細(xì)地說明。也提出了該如何來解決這些問題的具體的建議。

1.C 段落大意題。根據(jù)本段2,3，4行how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.可知本段是講述的是導(dǎo)致生態(tài)破壞的具體的原因。故C項(xiàng)正確。

2.D 細(xì)節(jié)題。根據(jù)文章第四段The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.可知在mountains, isolated islands and coastal areas，動(dòng)物遷徙的機(jī)會(huì)很少，故D正確。

3.B 細(xì)節(jié)題。根據(jù)文章最后3段The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.和The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.以及 It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.說明ACD三段都是文章中提及的方法和途徑，只有B項(xiàng)文章沒有涉及。

4.C 推理題。根據(jù)It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.可知這個(gè)組織敦促當(dāng)?shù)貒�家發(fā)展一些計(jì)劃來減少氣候變化對(duì)野生動(dòng)物的影響。故該詞是指C項(xiàng)內(nèi)容。

5.A 主旨大意題。本文主要講述的是全球氣候的變化對(duì)野生動(dòng)物的影響，文章中舉了很多具體的例子來進(jìn)行詳細(xì)地說明。也提出了該如何來解決這些問題的具體的建議。故A正確。

考點(diǎn)：考查環(huán)境保護(hù)類短文閱讀

點(diǎn)評(píng)：本文主要講述的是全球氣候的變化對(duì)野生動(dòng)物的影響，文章中舉了很多具體的例子來進(jìn)行詳細(xì)地說明。也提出了該如何來解決這些問題的具體的建議。要求考生在閱讀理解整體語篇的基礎(chǔ)上，把握文章的真正內(nèi)涵。要吃透文章的字面意思，從字里行間捕捉有用的提示和線索，這是推理的前提和基礎(chǔ);要對(duì)文字的表面信息進(jìn)行挖掘加工，由表入里，由淺入深，從具體到抽象，從非凡到一般，通過分析、綜合、判定等，進(jìn)行深層處理，符合邏輯地推理。不能就是論事，斷章取義，以偏概全。要忠實(shí)于原文，以文章提供的事實(shí)和線索為依據(jù)。
