这个属于不定式的一个结构：
wh-+to-v
wh-:what,how,when,where,who等
这个结构常用作主语、宾语、表语,相当于一个名词从句.
如：
I don't know how to do this.=I don't know how I should do this.
What to do is still unknown.
=What we should do is still unknown.

how to do sth 引导的是个从句.还是仅作为一个短语? how to do引导的从句是什么从句在hear的常见短语中,是hear to do sth 还是hear doing sth 还是hear do sth. suggest sb to do sth 还是suggest sb doing sth 那个短语是正确的? 初中所有的英语短语例如：made do、practice doing sth（好象是= =）、how to do sth have to do sth是句型还是短语? sth to do 这是一个名词性短语吗 mind有一个是加to do sth.的短语是哪个英语高手请进帮忙造个句子要用make up one's mind to do sth和in which 引导的定语从句 It's time to do sth是固定用time to do sth,还是说名词加to 加do sth 有个这样的 try to do sth 这里的不定式to短语是作宾语,那么这个时候try是及物动词还是不及物动词 to advice sb that should do sth.看到一个句子,引导词修饰sb?这是个什么从句?
