Despite recent increases in sales and cash flow that have propelled automobile companies' common stocks to new highs, several industry analysts expect automakers, in order to conserve cash, to set dividends more conservatively than they were
A. to set dividends more conservatively than they were
B. to set dividends more conservatively than they have been
C. to be more conservative than they have been in setting dividends
D. that they will be more conservative than they were in setting dividends
E. that they will be more conservative than they have been to set dividends
选C， 我当时选了B 。后来琢磨了下是原因是 conservatively 副词修饰动词 set 不太对。 而且主语是automakers， 是人 ，因此用conservative更好。
但B作为比较句子，than后面的 they have been 算不算错了？作者: UlysessHope 时间: 2011-9-2 20:46
个人觉得set 不是个实义动词么， 比较的时候第二个应该补出do或do的其他形式吧 如did/have done/have been doing
expect automakers to be more conservative than they have been这里是因为前面有to be 所以后面补出了have been，同是系动词
