一道SAT语法题The agency reports that by rigorously enforcing regulations,industral pollution has been susscessfully reduced to acceptable levels.这句怎么不对了? 英语
网友回答
【答案】 The agency reports that by rigorously enforcing regulations, 【industrial】 pollution has been 【successfully】 reduced to acceptable levels.
句意：媒体报道称通过严厉的强制管理,工业污染已经被减少到可接受的程度.
原句汉语意思好像通顺,但实际上英语表达失误,出现了“悬垂现象”,即后面主语industrial pollution 缺少实际上的动作执行者.换句话说,industrial pollution 的动作主体既不是The agency,也不是regulations,他们都不能够发出“减少污染”这个动作.
可以修改如下,并对比体会：
The agency reports that by rigorously enforcing regulations, we have 【successfully】 reduced 【industrial】 pollution to acceptable levels.
