1、特殊疑问词动词不定式的用法归纳“特殊疑问词动词不定式”的用法归纳一由两部分构成:疑问词和动词不定式(wh-+to do)。疑问词部分包括疑问代词who, whom, what, which和whose以及疑问副词when,where和how。此外,连接词“whether”也适用.它主要具有以下几种功能:当主语,如: When to hold the meeting has not yet been decided. Where to live is a problem.当宾语,常接在forget,findout,discuss,decide,tell,teach,know,learn,wond

The question is who to elect.当名词同位语,如: Tom had no idea which book to read first.The question whether to confess troubled t
3、he girl.用于宾语补足语,双重宾语。某些动词后可接“sb.+疑问词+不定式”构成的双重宾语,这类动词常用的有advise, ask, show, teach, tell等如: I cantell you where to get this book.I ask her how to learn English.He will advise you what to do.Will you show me how to use the machine?(6)作介词宾语:某些介词后面可接疑问词不定式作宾语,这类介词常用的有about, as, from, in, of, on,with等。例如
