142. (32496-!-item-!-188;#058&006253) According to a 1996 study published in the Journal of Human Resources, Americans of Middle Eastern descent were twice as likely as was the national average to be self-employed. (A) as was the national average to be self-employed (B) as the average American to be self-employed (C) as the national average that they would be self-employed (D) to be self-employed than was the average American (E) that they would be self-employed than was the national average 这道题目的正确答案是B,我不太明白national average是什么东西啊?觉得正确答案的average American也有问题,应该是单数可数名词不能单独存在啊,怎么还用单数呢?而且它和Americans of Middle Eastern descent也不对称啊!还有一个问题,was可以省吗?解释说可以,但是我不知道为什么,谢谢大家。 |
