在很多的gmat备考人中，大部分都gmat语法全解都有所了解，对与很多人来说对动词的补出原则是否了解呢?下面就来看看如何理解gmat语法备考中动词补出原则。
比较中是否要补出动词，一切看是否有歧义。但是当省略了也没有歧义的时候，补出和不补出动词在很多时候就不是绝对性的判断标准à只能用于相对性的比较。
比较中大原则还是看是否有歧义，具体的在庖丁解牛里面也有说，这里只是特别说一下as likely as…和more than的应用：
(一)as likely as:
(1) According to a 1996 study published in the Journal of Human Resources, Americans of Middle Eastern descent were twice as likely as the average American to be self-employed.
à不补出，是因为to do是放在后面了，不可能有歧义。
类似1：The Arthritis Research Institute of America advises women of color that they are twice as likely as White women to get osteoarthritis of the knee.
类似2：According to a survey of graduating medical students conducted by the Association of American Medical Colleges, minority graduates are nearly four times as likely as other graduates to plan on practicing in socioeconomically deprived areas.
(2)According to a new report by the surgeon general, women with less than a high school education were three times as likely to begin smoking as women who went to college.
à不补出，这里to do放在前面还是没有补出were，因为没有歧义。
(3) Traffic safety officials predict that drivers will be as likely to exceed the proposed speed limit as they are the current one.
à补出。这个例外是因为不同点the current one是宾语，为了表明它是宾语，所以要加上主谓。
所以要注意：有宾语和没有宾语是不同的。
(二)more than:
(1) 主语比较1：
Stresses that girls experience are more likely to result in depression than are those that boys experience.
à补出，主语比较，因为than前面比较成分已经包含了完整主谓宾，所以要补出are来表明是主语比较。
类似1：prep2-132. A study published in the British Medical Journal showed that women who ate nuts more than five times a week were about one third less likely to suffer from coronary heart disease than were those who ate no nuts at all.
