疑問詞是疑問代詞“who, whom, what, which, whose”和疑問副詞“when, where, how, why ”。此外，連接詞“whether”也適用。
“疑問詞+不定式動詞”結(jié)構(gòu)有何功用呢?其主要功用有下列五種：
⑴當主語，如：
When to hold the meeting has not yet been decided.
Where to live is a problem.
How to cope with the rising cost of living becomes a daily discussion topic.
⑵當賓語，如：
We must know what to say at a meeting.
He could not tell whom to trust.
Do you know how to play bridge?
⑶當補足語，如：
The problem is where to find the financial aid.
The question is who to elect.
⑷當名詞同位語，如：
Tom had no idea which book to read first.
Do you have a rough impression how to do it?
⑸當賓語補足語，如：
Jim is not sure whose to choose.
Mary and John are not certain whether to get married or not.
適用于“疑問詞+不定式動詞”的動詞包括：“know, see, decide, tell, ask, consider, discover, explain, forget, guess, hear, imagine, inquire, learn, remember, think, wonder, understand”等。
有點值得特別注意的是：當這結(jié)構(gòu)當賓語時，它的作用等于名詞分句，例如：
I could not decide which dictonary to buy. / I could not decide which dictionary I should buy.
Jack did not know where to find such a good teacher./ Jack did not know where he could find such a good teacher.
有些動詞，如“ask, show, tell, advise, inform, teach”等，可以先有個賓語，然后才接著加上適當?shù)摹耙蓡栐~+不定式動詞” 結(jié)構(gòu)。例如：
The chief technician showed the apprentice how to repair the machine.
Have you told him where to get the application form?
綜上所述，可見“疑問詞+不定式動詞”結(jié)構(gòu)是個形象清新，既容易用又不容易出錯的特別結(jié)構(gòu)，可以多多運用。
