By installing special electric pumps, farmers' houses could be heated by the warmth from cows's milk,accoring to one agricultural engineer.

A farmers' houses could be heated by the warmth from cows's milk,accoring to one agricultural engineer.

B the warmth from cows's milk could be used by farmers to heat their houses, according to one agricultural engineer

C one agricultural engineer reports that farmers could use the warmth from cows's milk to heat their houses

D farmers, according to one agricultural engineer, could use the warmth from cows' milk to heat their houses

E one agricultural engineer reports that farmers' houses could be heated by the warmth from cows' milk

答案为A，我选的是C， installing sepcial electric pumps 主语不是应当是agricultural engineer 吗？

这个题，我也迷糊了，我开始选D，请教：

介词之后的动名词的结构是否不需要，逻辑主语一致。

大全的answer是D.
應該是D.
因為"By installing special electric pumps"是adverb phrase, 所以B, C&E錯.
by doing something的邏輯主語就主句的主語, 所以A錯.

对，我突然想起来：只有当 By结构引导的是被动结构的时候， By之后的动名词（是实际上的主语），不需要考虑主谓一致，其余情况，做adverbial phrase的时候，都要主语一致。
