There is a widespread belief in the United States and Western Europe that young people have a smaller commitment to work and a career than their parents and grandparents and that the source of the change lies in the collapse of the "work ethic."
(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
这道题答案是D
我想请问一下这个比较结构的后半部分补出一个had，我认为应该补出来的助动词是did，因为我认为前半部分中的have并不是完成时态的助动词，是动词表示“有”的意思，为什么后半部分补出来的是had而不是did呢？作者: painsper 时间: 2010-6-19 22:29
我觉得这里的had也不是助动词吧？应该是have的过去式，就好像我说“You have more stories than I have”，不能说成是You have more stories than I do吧？作者: xiangzhengj 时间: 2010-6-24 06:43
比较完美原则啦。不一定就是一定全对，只是相对错得少。很多题都是这样的。如果非要追究
就可以把它看成是比较结构中的省略结构。had后省略了commitment。是可以的这样。
