题目

(1)Ungreatful children are critized and despised in their neighbourhood.
句中的那个介词为什么用in
(2)It is urgent for us to address this phenomenon so as to guarantee the welfare of elderly people.

答案

1.In neighbourhood 有在邻居之间的意思,这里用in 是因为in有在……在内的含义
2.　of和welfare没关系,而是句意的问题,of　表示……的,可以连接前后两个名词,这里welfare　of　elderly　people　表示老年人的福利
