比较结构同时要求平行
主谓宾成分具全的比较句，有两种情况：1）宾语的比较；2）主语的比较。在GMAT考试当中， 如果遇到主语比较的情况，一般要求第二个句子补出系动词或助动词，以避免歧义。 如：I eat apple faster than you do. 该句为主语之间的比较，句子中的do是不可以省略的。因为" 如果去掉do，则形成宾语比较句，apple和you进行比较，产生我吃苹果比吃你快的逻辑错误。 但是在只有主谓，没有宾语的句子中，由于没有宾语，所以不会产生上述歧义，所以不需要补充 系动词/助动词。如：I earn more than you.不需要补充do。如果补充了do，反而会构成罗嗦的错误。
考比较的平行：
women who ate were ……than women/those who ate were完美的平行。women eating were than women/those eating were才是完美的平行
前后时态一样，去掉不引起歧义，后面的were可以加可以不加，但因为两个比较内容太长隔得太远，为便于理解，were最好带上。
这道题出得很烂！脑子有病才会理解成women suffers from women，按语意不会引起歧义的就可以省略谓语动词
than those who ate no nuts at all were，those是个名词，who ate no nuts at all 是定语从句修饰those，其中who是代词作主语，这里who在从句作主语，不能省略；如果作宾语可以省略，如：than those I contacted with last week were
凡是有主语有宾语的句子，后面带了比较的，都需要注意主语和宾语两个名词的存在所可能引起的究竟在跟主语还是宾语比较的歧义
如SVO, like sth，到底是S like sth还是VO like V sth，错，改成S， like sth，VO
SVO than sth，错，改成SVO than sth V
SVO rather than/instead of sth,错，改成SVO rather than/instead of sth V
D 主语的比较，如果有宾语，常补出助动词系动词，避免歧义 误以为是宾语的比较
本题歧义：less likely to suffer from A than B
1.D 主语的比较，如果有宾语，常补出助动词系动词，避免歧义 误以为是宾语的比较
本题歧义：less likely to suffer from A than B
2.E than 后经常倒装，因为主语有从句太长，避免头重脚轻
E选项是倒装
than those who ate no nuts at all were likely to suffer from coronary heart disease.
比较对象是【可能性】，不是【人】
