（同位语）二、“特殊疑问词＋动词不定式”结构经常用在某些动词后作宾语，类似的动词有：tell, show, know, learn, teach, find out, forget, wonder, remember等。
如：1，I’ll show you how to do it.我要让你看看如何做这件事。
,2，You’d better find out where to put it.你最好弄清楚要把它放在哪里。
作双重宾语（宾语补足语）：某些动词后面可接"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。
例如：He will advise you what to do.他会建议你们做什么Will you show me how to use this machine?你能示范教我如何使用这部机器吗？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。

三、“特殊疑问词＋动词不定式”这种结构可以把复合句转为简单句。
如：1，I don’t know what I’ll do next.= I don’t know what to do next.2，The doctor told him when he should take the medicine.= The doctor told him when to take the medicine.同样，因为“特殊疑问词＋动词不定式”这种结构相当于一个名词性从句，所以可用同等成分的从句代替，从而把简单句转换为复合句。
改写时只需在疑问词后加上适当的主语，并把不定式改为适当的形式的谓语即可。
如：1，Li Ping doesn’t know why to learn English.= Li Ping doesn’t know why he should learn English.2，Which to choose is important.= Which we should choose is important.3，The question is where to go.= The question is where we should go.四、“特殊疑问词＋动词不定式”这种结构可构成独立问句。
如：What to do? 怎么办？How to get rid of the trouble? 如何摆脱困境？然而，这个结构看似简单，但也容易出错，有几点是需要我们注意的：易错一：按照英语语法的习惯，疑问副词why后不直接跟动词不定式。
如：误：I don't know why to choose that dictionary. （X）正：I don’t know why you must choose that dictionary.但它可以接不带to的动词不定式（即动词原形），构成Why do sth.?/Why not do sth? 结构。
肯定形式表示某动作是不必要的或没有意义的，而否定形式则用于向某人提建议和表达看法，相当于祈使句。
Today is Sunday. Why not go out to relax yourself?今天是周日，干嘛不出去轻松一下呢？Why pay more at other shops? We have the best value.为什么花更多的钱到其他商店去买？我们这里物美价廉。
另外，还需要注意的是：why not这个结构的否定式通常只用于谈论现在和将来，而不用于谈论过去。
如：误：Why not clean the room yesterday? （X）正：Why didn’t you clean the room yesterday?易错二：有些动词可以直接跟不定式作宾语，但有些动词是不能直接跟不定式作宾语的，这些不能直接跟不定式的动词它们的后面可以接“疑问词+不定式”结构作宾语。
这类动词主要有：know, suggest, consider, discover, discuss, explain, understand, wonder等。
如：He knows how to play the piano.他会弹钢琴。
We never discovered how to open the box.我们一直未发现如何打开这个盒子。
Can you explain how to make a cake?你可以给我解释一下怎么做蛋糕吗？有些动词，如tell, ask, show, advise, teach, inform等，还可以先加上一个间接宾语，之后再加上“疑问词+不定式”结构作直接宾语。
如：Please tell us where to show our tickets.请告诉我们在哪里验票。
Have you told him where to get the application form?你告诉他到哪里去拿申请表了吗？易错三：“疑问词+不定式”结构，通常不用于动词think的现在式和过去式之后，但可以用于think的其他形式之后（如现在进行式），如：I’m thinking what to do next.我在想接下来要做什么。
I’m thinking how to use this computer.我在想如何使用这台电脑。
有时，此结构还可以用在有助动词的think之后，如：She couldn’t think what to give the children for Christmas.她想不出圣诞节送孩子们什么礼物。
易错四：在“which+不定式”结构中，which有时可以是疑问词，那就和我们所说的“疑问词+不定式”结构一样。
如：I can’t decide which to choose.我不能决定选哪一个好。
Did you ask her which to buy?你问没问她该买哪一个？但有时which可能是关系代词，那么这个结构就相当于一个定语从句了，此时主要用于介词之后作宾语。
如：She must have time in which to grow calm.她必须有冷静下来的时间。
=She must have time in which she can grow calm.Allow me one minute in which to change my costumes.给我一点时间来卸装。
=Allow me one minute in which I can change my costumes.结束。
