介词的选择,这几句为什么用介词of?
Britain has recently had a high level of unemployment-put the same is true______many other countries.
A at B from C of D to
The study you have been making ________the ancient Chinese characters is an instructive job.
A to B for C of D from
The little that I have seen________his research is satisfactory.
A to B in C of D from
答案都是of的选项,但是很不理解为什么用of
如果有其他的例句就更好了.

Answer 1

of other countries 表示所属关系 其实省略的是 the unemployment level of other countries
the study of 关于什么的研究 you have been making 是定语从句
the little of his research 他研究中的一小部分 that I have seen 是定语从句
你主要分清楚句子成分就好理解了哈
