GMAT语法知识点：比较中的省略.

　　看到网上经常会有碰到问到比较中的省略这一GMAT语法知识点，为此澳际小编特进行收集整理，将比较中的省略这一GMAT语法知识点分享给大家，希望对大家有所帮助，文中观点仅供参考。

　　省略的名词，其单复数必须一致。如果单复数不一致，需要补出名词。

　　Her company did better last year than [those] of her competitors. 错，Those无指代。

　　Her company did better last year than [the companies] of her competitors. 对

　　省略的内容，可以是动词、单位、整个句子。

　　I walk fater than James [walks].

　　Whereas I drink 2 quarters of milk a day, my friend drinks 3 [quaters].

　　I walk as fast now as [I walked] when I was a child.

　　状语比较的时候，可以省略than后面整个主句，不管时态是否一致。

　　例如上面的句子，I walk 与 I walked时态不一致，但是都省略了，比较的重点是时间——now和when I was a child

　　时间状语的比较，能否省略取决于than前面是否有相应的时间状语。有的话，than后面主句可以省略;没有的话，than后面需要补出主谓，以避免比较对象上的歧义。

　　To develop more accurate population forecasts, demographers would have to know a great deal more than(they do) now about the social and economic determinants of fertility.

　　[they do]不能省略，因为than前面没有相应的状语结构

　　A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than (it was) five years ago.

　　[it was]不能省略，因为than前面没有相应的状语结构

　　Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than in any previous election.

　　[in any previous election]前面没有补出[that]，因为than前面有1992与in any previous year相对应。

　　完整主谓宾结构是被动语态的时候，状语比较，省略的通常还是than后面整个句子(与主动语态相同处理)，如果不采用省略结构，通常是【主语+补出助动词be】。如果仅补出be后面的done而省略Be，要看后面是否存在语义上的歧义。

　　例1：【In Japan】 elderly people are treated with far GREATER respect THAN they are 【in most Western countries】

　　例 2：According to public health officials, in 1998 Massachusetts became the first state in which more babies were born to women【over the age of thirty】 than【under it】. 仅补出born，会产生under it修饰born的歧义。

　　例3：In no other historical sighting did Halley&aposs Comet cause such a worldwide sensation as in its return of 1910–1911.
