(A) a smaller commitment to work and a career than their parents and grandparents
(B) less of a commitment to work and a career than their parents and grandparents
(C) a smaller commitment to work and a career than that of their parents and grandparents
(D) less of a commitment to work and a career than their parents and grandparents had
(E) a lessening of the commitment to work and a career that their parents and grandparents had
答案D
不大明白前面young people have 这个have是实意动词，为什么后面补充要补助动词？而不是用did呢？谢谢！

哈哈 不用NN啦 小J给你解释清楚了 这里其实是less of a commitment to work and a career than their parents and grandparents had （had）第二个had是have的过去时 have是实义动词 补出的had的助动词 由于前后时态不同 所以有点奇怪 后边是过去完成时态 因为父辈的梦想已经在过去结束了 合理体现完成 understand？作者: keaneice 时间: 2009-12-10 01:01
