一个英语从句的问题
Some beaches are frequently contaminated by untreated sewage that flows into the ocean,which can last for several days
这个里的which,用的对吗
可不可以指代前面污染的这件事?
我就是想说
which可不可以指代污染持续很长时间
非限定性定语从句的指代问题
不可以这样.根据一般现在时的特点,“经常做某事”本身即是永久持续的,故不可last for some time.要表达你的意思,可以改成下面这样:
Some beaches are frequently contaminated for several days by untreated sewage that flows into the ocean.
