雅思阅读多项选择题解析

雅思阅读中的选择题有两种形式，一是四选一的单选题，二是提供五个以上选项的多选题。这种题目考生比较熟悉。在雅思阅读考试中的选择题也是细节题，一般不会要求考生对文章内容进行推理或对文章主旨大意进行总结，只要考生能找到文中相应的信息点就可以，比较容易。

攻略

·分析题干后阅读文章，在原文中寻找题干需要的信息点。

·选择题常用的排除法在这里也适用。

The average air mperature at the surface of the earth has risen this century, as has the temperature of oceansurface waters. Because water expands as it heats, a warmer ocean means higher sea levels. We cannot saydefinitely that the temperature rises are due to the greenhouse effect: the heating may be part of a之natural:

variability over a long time-scale that we have not yet recognised in our short 100 years of recording. However,assuming the build-up of greenhouse gases is responsible, and that the warming will continue, scientists andinhabitants of low-lying coastal areas-would like to know the extent of future sea level risesScientists do not know for sure why the air and surface of ocean temperatures are rising because

A. there is too much variability.

B. there is not enough variability

C. they have not been recording these temperatures for enough time.

D. the changes have only been noticed for 100 years.

分析:题目本身没有特殊的中心词(人名、地名、时间或数字)，所以考生需要回到原文寻找语言重现。原文第三句We cannot say definitely that the temperature rises are due to the greenhouse effect...

实际上就是题干的同义重现，答案即下文的…the heating may be part of a "natural" variability over along time-scale that we have not yet recognised in our short 100 years of recording.，这个句子解释了原因 .

即温度上升也许是自然变化的一部分，而我们在短短100年的记录过程中还没有认识到这种变化规律。选项C与D都是原文的重现，但选项D用的动词notice与原文record意思不符，所以选项C更接近原文的意思。标签：雅思阅读多项选择题解析
