　　比较类考题是GMAT中经常出现的类型，很容易出错。

　　做题时首先要搞清楚几个问题：

　　1.

　　谁和谁比较?是名词还是动词，白勇语法里面有详细的描述。

　　2.

　　谁和谁比的结构是什么样的?读起来句子意思会不会改变?

　　3.

　　比较类型：more than结构，同位语结构，as…as结构，times结构等

　　C. of personal spending in the July-September quarter, that it more than doubled

　　D. of personal spending in the July-September quarter more than doubling that of

　　考察点：动词形式，逻辑预测

　　句子首先说的是根据过去趋势对未来的一个expectation，expectation作为一个虚拟语气的标志词后面考虑用would等虚拟语气词。

　　一般过去时不能表达出未来预测的感觉，expectation的期望

　　B.

　　D.
