【MBAChina网讯】当你想表示一个数量比其他的大多少时，你有以下几种选择：

一、把more和less放在合适的位置

当more在“形容词+名词”之前时，要注意有歧义，如We have even MORE efficient engines than before.

这句话的意思是有更多的efficient engines(they have a greater quantity of efficient engines)?还是engines更efficient了(do they have engines that are more efficient?)?

下面的说法就能够解决上述歧义

Right: We have even MORE engines that are efficient than before. (更多的engines)

Right: We have engines even MORE efficient than before. (更efficient)

二、在GMAT考试中，有时会出现比较少见的比较词

这些少见的比较词中包括动词，如exceed or surpass，此时要确定比较的双方是否平行，看下面的例子

Wrong: The incidence of the disease among men exceeds women. (比率和women相比，错误)

In the construction X exceeds Y, the subject X and the object Y must be parallel.

改正上述错误，你可以重复使用incidence或加入代词that，看下面例句

Right: The incidence of the disease among men EXCEEDS the incidence among women.

Right: The incidence of the disease among men EXCEEDS its incidence among women.

Right: The incidence of the disease among men EXCEEDS that among women.

此外，in addition to这个词组要注意

At the beginning of a sentence, you can use this construction to add another example to the subject. You can also use it to add another example to a different noun in the sentence, such as the object of the verb or some other noun:

Right: IN ADDITION TO taxes, death is inevitable. (增加主语的example)

Right: IN ADDITION TO Munster cheese, I like Swiss.(增加宾语的example)
