语意转换类

语意转换类阅读理解属于细节理解类的范畴，那么我们如何做语意转换类题目呢？

[例文]

To figure out how quicky trees were growing，researchers tracked their diameters (the width of their trunks) between 2005 and 2014.A tree's diameter increases as it grows，just as a person's waist size increases as they gain weight.The research has shown about half the weight of a tree is carbon，while most of the rest is water.Over the nine years' tracking，the researchers found city trees absorbed four times as much carbon dioxide from the air as forest trees.However，they were twice as likely to die.So over the lifetime of each type of tree，forest trees actually absorbed more carbon dioxide.

◆How do city trees differ from forest trees of the same type over the lifetime in the research?

A．They could live twice longer than forest trees.

B．They took in less carbon dioxide than forest trees.

C．They could absorb more carbon dioxide than forest trees.

D．They weighted heavier than forest trees.

[技巧点拨]　

语意转换类题目，需要将题目信息与原文相关信息进行语意上的转换，两者存在表述上的差异。解答这类题目时可带着问题，有针对性地扫读全文，迅速锁定相关语句，再对相关部分进行分析对比，找出答案。

B　[根据“However，they were twice as likely to die.So over the lifetime of each type of tree，forest trees actually absorbed more carbon dioxide.”可知，生长在森林中的树一生所吸收的二氧化碳量比生长在城市中的树多。故生长在城市里的树一生的二氧化碳吸收量比森林中的树少。故选B。]
