21224—(张)but i don't know where to start.3747
想问:
1—where to start:这是一种什么结构
类似的还有:but i don't know which one to choose.
就是疑问代词(what/where/which/how……)加不定式充当宾语的结构
如:I don't konw what to do next.I am thinking about which one to choose.
21224—(张)but i don't know where to start.3747 想问:1—where to
英语中,有些动词,如 don't know,ask,wonder 等动词后,常常可以跟“疑问词 + 不定式”这种结构作宾语,如:
* I don't know where to start 我不知道开始于何处.
* He asked me how to get to the station.他问我怎么样才能到达车站.
* I wonder what to do.我想知道该做些什么.
这种结构完全可以用宾语从句取代,如上述例句都可改写如下:
* I don't know where I will start.
* He asked me how he can get to the station.
* I wonder what I should do.
