问题 By installing special electric pumps, farmers’ houses could be heated by the warmth from cows’ milk, according to one agricultural engineer.

选项 A、farmers’ houses could be heated by the warmth from cows’ milk, according to one agricultural engineer
B、the warmth from cows’ 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’ 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 warm-th from cows’ milk

答案D

解析 句首为by installing,而划线部分的主句主语为farmer’s house,显然farmers house是物而不是人,不可能“安装”,由此可判断A、B错。具体讲有两个原因,其一:主语不是分词短语的逻辑主语;其二:主句都用了被动语态,且都出现了动作执行者(用by连接);C、D、E的主句主语均为人、工程师或农场主。有人认为“工程师”理应“负责安装”工作,于是排除D而在E中寻找答案。其实,这里应该是farmer作主句的主语,而不应是engineer,why?假设C对,代入原句,就译为: “工程师通过安装特殊电泵,他们报道了…”,让人产生歧义:工程师只有通过安装电泵才可报道这则消息,这显然是不对的。应选farmer作主句主语,可译为“根据一个农业工程师的报道,农场主们通过安装特殊电泵,就可以用牛奶的热量来给房子供暖”。
