A: 两个they不是指代同一个对象
B: correct C: 两个they不是指代同一个对象
D: but不能引导条件状语从句
E: 同上 我不明白的是,大家都说第一个THEY是指的METHODS,第二个THEY是指POLLUTANTS.如果这样的话这题好解决。可是大家是怎么慧眼可以明白两个THEY其实是有不同的指代呢?我就总觉得都是指METHOD一个这样的名词啊. 我的问题就是,大家是怎么判断代词的指代呢?就单靠单复数吗?还是靠逻辑理解. 如果靠逻辑理解的话我个人认为就不存在指代混乱的问题。因为大家都是正常人可以正确理解句子的意思,既然都知道是逻辑错误的指代就不会那么去理解了。那么代词就可以随心所欲的使用。无论指代什么反正读者都能理解。 所以指代问题我一直很模糊,不知道到底有什么规律可以遵循。 希望NN给指点。
