Question

【題目】 More than half of the birds in Washington are at risk of extinction because of climate change. That's according to a new national report from the Audubon Society, which gives detailed analysis of climate effects on about 600 species of North American birds.

It's based on more than 140 million observations of birds across the US, Mexico and Canada. Audubon scientists looked at the likely effects of sea-level rise, urbanization, drought, extreme spring heat, increased fires, heavy rain and other factors.

But it doesn't just spell out a doomsday scenario (世界末日).Instead, it offers a range of effects and warming, depending on how much carbon humans add to the atmosphere.

"It is truly an existential threat (威脅), not only to birds but to people,” said Doug Santoni, board chair of Audubon Washington, who looked into the report as soon as it came out.

Santoni says he was struck to see the vulnerability (脆弱)of a common “ backyard bird" , the dark-eyed junco. It's one that many first-time birders become familiar with as they learn how to identify species based on their markings and other traits. Currently in Washington, you can count on juncos to show up at your feeder, year round. Extreme spring heat, increased fires and heavy rain are the kinds of changes that will force birds like these north, or kill them off if they fail to adapt.

Trina Bayard, director of bird conservation at Audubon’s Washington chapter, says, "It's certainly a very serious warning report," but adds that there’s still hope. “If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. ”

【1】What can we know about the new report?

A.It analyses the species of birds in detail.

B.It's issued by watching 600 bird species.

C.It shows the end of North American birds.

D.It reports the threat some birds are facing.

【2】What may Santoni probably agree with?

A.Climate change is a threat only to birds.

B.It's too late to take action to save the birds.

C.The current situation of the birds is worrying.

D.It's common that birds are affected by climate change.

【3】Which of the following can help these birds according to Trina?

A.Lowering present temperatures.

B.Reducing our daily emissions.

C.Making them adapt to climate change.

D.Encouraging people to protect them.

【4】What can be the best title for the text?

A.Climate change threatens many Washington bird species.

B.A new report about 600 species of North American birds.

C.Different attitudes towards the situation of bird species.

D.Climate change makes different kinds of species at risk.

Answer 1

【答案】

【1】D

【2】C

【3】B

【4】A

【解析】

本文是說明文。氣候變化使得華盛頓州一半以上的鳥類處于危險之中，一項新的報道詳細(xì)闡述了氣候變化對北美600多種鳥類物種的影響。鳥類專家稱“雖然情況很糟糕，但是通過穩(wěn)定目前的溫度和減少排放等方法，我們可以減少這些影響”。

【1】

細(xì)節(jié)理解題。根據(jù)前三段中More than half of the birds in Washington are at risk of extinction because of climate change. 和But it doesn't just spell out a doomsday scenario (世界末日).可知，這篇新的報告詳細(xì)敘述了氣候變化對北美一些鳥類物種的影響，這種威脅是很嚴(yán)重的，但不是說這些鳥類的世界末日到了。故選D項。

【2】

推理判斷題。根據(jù)第四、五兩段內(nèi)容It is truly an existential threat (威脅), not only to birds but to people,和dark-eyed junco的例子可知，Santoni認(rèn)為，氣候變化是真正影響鳥類和人類生存的威脅。他對于這種普通的dark-eyed junco鳥類受到的傷害和影響感到很震驚。這些都說明鳥類的現(xiàn)狀令人擔(dān)憂，故選C項。

【3】

細(xì)節(jié)理解題。根據(jù)最后一段中最后一句If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. 可知，我們可以通過穩(wěn)定目前的溫度和減少排放來減少對這些鳥類的影響。故選B項。

【4】

主旨大意題。根據(jù)第一段More than half of the birds in Washington are at risk of extinction because of climate change.及下文內(nèi)容可知文章主要介紹：一項新的報告說明氣候變化使得華盛頓州一半以上的鳥類處于危險之中。這項報告詳細(xì)闡述了氣候變化對北美600左右的鳥類物種的影響。Climate change threatens many Washington bird species.概括了全文內(nèi)容，適合作為標(biāo)題，故選A項。
