Question

【题目】 In what ways has global warming affected our world? Rising sea levels, melting glaciers (冰山)and extreme weather are just a few examples.【1】.

Ending racial(种族的) differences

【2】This can force people to leave their homelands and move to other places. One result of this is gene flow (基因). This term describes the mixing of genes between populations, Scott Solomon, a biologist at Rice University in the US, told the Daily Mail

【3】More people will have olive(橄榄色的) or brown-colored skin. Racism could be lessened or disappear, Solomon said.

Making insects hungrier

According to Science Daily, when it is warmer, insects' body temperatures go up along with the outside temperature. This is very different from humans and other mammals(哺乳动物) ,who can keep their body temperature at a certain level without being affected by the weather.

Higher body temperatures can increase the insects' metabolism(新陈代谢

【4】In addition, Increasing temperatures also make insects breed (繁殖 )more quickly

Helping scientists find historic sites

【5】After the dry weather turned the country’s green landscape yellow, people noticed some usually pattern（图案）in the middle of a field . That’s because grass that grows above historic has a different color ang height from other grass. This helped people see the patterns.

After studying these patterns, scientists found Neolithic(新石器时代) monuments(纪念碑) and a Roman farm

A. Britain had a very dry and hot summer this year because of global warming ,the Independent reported.

B. But did you know that global warming can also bring other, less obvious long-term changes?

C. In just 125 years, there may be fewer people with dark skin or pale skin.

D. Global warming causes droughts and poor harvests.

E. This makes them hungrier, so they need to eat more.

Answer 1

【答案】

【1】B

【2】D

【3】C

【4】E

【5】A

【解析】

本文主要介绍了全球变暖带来的几个明显的变化比如海平面上升、冰川融化和极端天气，还带来了一些长期的不太明显的变化。

【1】推断题。根据上句Rising sea levels, melting glaciers (冰山)and extreme weather are just a few examples.海平面上升、冰川融化和极端天气只是几个例子。可知，接下来可能会有其他的例子，可能还会引起其他的问题，以及文章下面列举的几个例子可以看出，这里应该选择B选项，But did you know that global warming can also bring other, less obvious long-term changes?但你知道全球变暖也会带来其他不那么明显的长期变化吗?所以本题选择B。

【2】推断题。根据下文的This can force people to leave their homelands and move to other places. One result of this is gene flow (基因). This term describes the mixing of genes between populations, Scott Solomon, a biologist at Rice University in the US, told the Daily Mail这可能会迫使人们离开自己的家乡，搬到其他地方去。这是基因流的一个结果(基因)。美国莱斯大学的生物学家斯科特·所罗门在接受《每日邮报》采访时表示，这个词描述的是基因在不同人群中的混合。可知，可能一个地方的人会搬到其他很多地方，这样人们这样流动会结束种族的差异，所以选择D。

【3】推理题。根据文中More people will have olive(橄榄色的) or brown-colored skin. Racism could be lessened or disappear, Solomon said.更多的人将有橄榄(橄榄色的)或棕色皮肤。所罗门说，种族主义可能会减少或消失。可知以后深色皮肤或浅色皮肤的人可能会越来越少了，所以本题选择C。

【4】推理题。根据文中Higher body temperatures can increase the insects' metabolism(新陈代谢）较高的体温可以增加昆虫的新陈代谢可以推断出，新陈代谢增加了，饿的就会更快了，吃的就会更多了，所以这里选择E。

【5】推理题。根据文中After the dry weather turned the country’s green landscape yellow, people noticed some usually pattern（图案）in the middle of a field . That’s because grass that grows above historic has a different color and height from other grass. This helped people see the patterns.干燥的天气之后,把国家的绿色景观变成黄色,人们通常注意到一些图案的一个领域。这是因为生长在历史之上的草和其他草有不同的颜色和高度。这有助于人们发现规律。可知，干燥的天气有助于历史遗址的发现，所以选择A。
