疑问副词什么时候做不定式to

疑问副词不能做不定式to.
但他们刻意放在不定式之前。去：
how to do it
where to go
when to start

楼主好, 副词是很活跃的,没有限定说它一定要放在什么位置. 另外,副词是修饰形容词和动词的, 你所说的不定式说白了还是to+动词原形, 说个例子: i answered promptly the question he asked me. 他问了我一个问题,我马上就回答了. i promptly answered the question he asked me. 转成不定式看下: i was asked to answer the question promptly. i was asked to promptly answer the question. 你看promptly在上面两句位置是不同的,但都是对的. 希望对你有帮助^^
