There is much that can be done.中that 可用which 来代替吗?
答：看什么情况.平时说话,口语中,你想用that就用that,想用which,就用which.我可以在网上找出很多这样的句子,且都不是中国人说的：
There is much which can be done to reduce the negative impact which a golf
course has on the environment,and to enhance the positive aspects....
There is no definite cure for chronic fatigue syndrome,but there is much which
can be done to help the patient manage their condition and live as full a ...
Irrespective of the origin of stress,there is much which can be done to prevent
stress becoming a problem and also to assist individuals who suffer from ...
Safety is obviously the primary consideration,and there is much which can be
done to improve this,with and without the use of baby insect repellent....
Furthermore,there is much which can be done about the situation.
不过,如果你不幸在中国人给你出的选择题中出现这两个选择,告诉你,选that绝对没错.这已经成为中国特色的考试语法了.看看上面的回答吧,谨慎的语法学家在书中所用的“常常,多用,一般多用”这样的字眼,都被他们省略掉了,变得很强,很硬,没有商量的余地了.
