比较结构

Americans of Middle Eastern descent were twice as likely as was the national average to be self-employed.

for a , americans.....as likely as the  national average was

for b,  americans .....as likely as the the average American

这道题我也错了，但是我不大同意ls的观点.

A,Americans of...were  as likely as the national average was

B,as the average American to be self-employed

Be 动词是否需要省略要看具体情况。著名的PREP里面有一个Stresses that girls experience are more likely to result in depression than are those boys experience. 因为than 前面是一个名词depression,所以要补上be动词。

 我认为这题的重点在于比较对象。national average 和Americans “人”不对称。同样prep也有一个题，an average global warming.../a global warming that average.Average 这个词既是名词又是形容词，出现在比较对象的对等上面很Tricky.
