Question

请问老师这句话的用词问题.
The internet has insteaded of teachers in many classrooms.
书上说要把insteaded of换成 replaced,解释是前者不可以当动词用,只能做副词／介词短语.
我还是不明白instead of为什么不能当动词用?
例如这句话：His success plays his luck instead of his skill.这里的instead of是介词短语吗?做副词的情况是什么样的?

Answer 1

instead of是短语介词 也就是 整个短语相当于一个介词.后面跟名词构成介词短语.instead是副词
原句是主谓宾结构 所以谓语 必须是行为动词
如果非要用 介词短语的话 这里 只能是作表语
如The internet has been instead of teachers in many classrooms.
不过这种表达不多见 因为该短语经常是作状语的
如The internet has been used in many classrooms instead of teachers‘ teaching
