  • do you know where to buy(buy) a washing machine?

    washing machine 清洗机

    where等疑问词后接不定式to 是一种结构

    例如:I don`t know how to choose them.

    I cannot decide where to go.

    疑问词what, who, which, when, where, how和连接词whether之后,可以跟带to的不定式,构成一个特殊的动词不定式短语,可以在句中作主语,宾语和表语.

    如:How to solve the problem is very important.如何解决这个问题是很重要的.(主语)

    He didn't know what to say. 他不知道该怎么说.(宾语)

    The question is where to find the source of water.问题是在什么地方能找到水源.(表语)
