begin是否有被动?
一般不是都说the class begins,the movie begins吗?
为什么这句The research is so designed that once begun nothing can be done to change it.
却用了被动?
1.begin的确有被动.
2.
1)begin既可以作不及物动词,如:the class begins和the movie begins等.
2)但是它也可以做及物动词,用法类似于start,后面可以直接加宾语.
如:I began my class with a humorous story.
变成被动即为:My class was begun with a joke (by me).
3)不过用做不及物动词时居多,上句的确也可以写成:
My class began with a humorous story.
3.楼主所给的例题即是begin做及物动词.
该句采用了状语从句的省略语法,即:
Once begun nothing can be done to change it.
=Once (it is begun) nothing can be done to change it.
如果此题begin为不及物动词,则没法采用该语法,因为状语从句省略时,要求从句的谓语动词必须以be动词开头.
