动词+疑问代(副)词+不定式这类动词

常见的有：advise,decide, discuss, find out, forget, inquire, know, learn, regard, remember, see, settle, teach, tell, think(=consider), understand, wonder等。这些疑问代(副)词有what, when, where, which, how, whether等,但不包括why,如：

when to speak before strangers.

who(m) to visit.

which one to choose.

You can decide whether to go forward or stay here.

when to see a doctor.
