Question

【題目】 In what ways has global warming changed our world? Rising sea levels, melting glaciers(冰川) are just a few examples. But did you know that global warming can also bring other changes?

Ending racial(種族的) differences

Global warming causes droughts and poor harvests. This can make people leave their homelands and move to other places. In just 125 years, there may be fewer people with dark skin or pale skin. More people will have brown-colored skin.

Making insects hungrier

When it is warmer, insects’ body temperatures go up along with the outside temperature. This is very different from humans, who can keep their body temperature at a certain level. Higher body temperatures can step up the insects metabolism(新陳代謝). This makes them hungrier, so they need to eat more. And this also makes insects bred(繁殖) more quickly．

Helping scientists find historic sites

Britain had a very dry and hot summer this year because of global warming. After the dry weather turned the country’s green landscape yellow, people noticed some unusual patterns in the middle of a field. That s because grass that grows above them has a different color and height from other grass. This helped people see the patterns. After studying these patterns, scientists found something old and a Roman farm.

【1】According to the passage, which skin color will be more common in the future?

A.Dark.B.Pale.C.Yellow.D.Brown.

【2】How will global warming make insects hungrier?

A.Because they will grow as big as humans.

B.Because only large insects can live in high temperatures.

C.Because their metabolism will go faster as temperatures are higher.

D.Because they can’t keep their body temperature at a certain level.

【3】Because of the hot weather, people in England found______________.

A.new landscapesB.grass with different colors

C.some unusual patterns in a fieldD.an old country under a field

【4】What can we infer from the story?

A.Global warming is not a problem at all.

B.Scientists are happy with global warming.

C.Global warming is happening more quickly.

D.Farmers will face problems because of global warming.

【2】C

【3】C

【4】B

【解析】

文章大意：本文講全球變暖改變了我們的世界，詳細(xì)介紹了幾種鮮為人知的改變——消滅種族差別、使昆蟲(chóng)更餓和幫助科學(xué)家找到歷史遺址。

【1】細(xì)節(jié)理解題。根據(jù)第3段中“More people will have brown-colored skin.”可知棕色皮膚的人類(lèi)將會(huì)更多。故選D。

【2】細(xì)節(jié)理解題。根據(jù)第5段中“Higher body temperatures can step up the insects metabolism(新陳代謝). This makes them hungrier”可知，新陳代謝加快導(dǎo)致昆蟲(chóng)更餓。故選C。

【3】細(xì)節(jié)理解題。根據(jù)第7段中“After the dry weather turned the country's green landscape yellow, people noticed some unusual patterns in the middle of a field.”可知炎熱的天氣使英國(guó)人發(fā)現(xiàn)了田野里的一些不尋常的圖案。故選C。

【4】推理判斷題。ACD選項(xiàng)全文沒(méi)有提及；根據(jù)第6段中“Helping scientists find historic sites”可知全球變暖可以幫助科學(xué)家找到遺址古跡，科學(xué)家應(yīng)該會(huì)跟高興。故選B。
