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


选项分析：
A. 实义动词to set(表达预测，将来时)与系动词were不平行，应该是: to set Div. more conservatively than they have done.


B. to set与have been不平行，要在been后面加上setting或改为have set以修正平行。


C. Correct；be + adj + in doing something很顺口, e.g. She is very active in posting questions on CD.；时态也很好：to be表示从现在开始的未来，have been 从过去到现在，时间轴上没有空缺


D. Expect sb. that搭配错误，只能用expect that或expect sb. to do；were的时态问题


E. 不能用Expect sb. that，同D； to set错误，应该改为in setting



想请问b为什么不平行，是因为时态还是什么？求解答

to do 和be不能平行

要平行的话，B选项应该改成then they have done

那to do和they have done怎么平行了？

因为都是do

系表结构和主谓结构不可平行，主谓结构和主谓结构可以平行。
