Question

英语问题 请解释：of which ,of what 在定语从句中有何作用?

Answer 1

1）Living in the western part of the country has its problems,of which obtaining fresh water is not the least.
生活在这个国家的西部有很多问题,其中获取新鲜水并非最难的（一个问题）.
本题确实应选择of ,这是一种特殊类型的定语从句,是用介词＋which 引导的.通常介词是看固定搭配的,比如这里用of是因为the problem of的搭配,并且此句主（Living）谓（has）宾（its problems）齐全,所以用which 不用what
2）Be the best of what you are!做最好的你就是成功 !
the best of 是固定 ,因为此句缺宾语所以用what不用which
你明白了么~
