A 这类动词中最常用的有 ask, decide, discover, find out, for- get,know, learn, remember, see(= understand/perceive),show+宾语, think, understand, want to know,wonder:

我不知道什么时候关掉机器。

我告诉她应该按哪一个按钮。
She couldnt think what to asy.
她想不出说什么。
(注意:这种结构不常用于动词think的现在式和过去式之后,但可以用于think的其他形式之后,或者如上面最后一个例句那样,用于前面还有一个助动词的think之后。)
B whether+不定式同样可以用于 want to know, wonder之后:
I wonder/wondered whether to write or phone.
我不知道应该写信还是应该打电话。
这种结构还可以用于表示否定意义或疑问意义的decide, know, remember和 think后面:
You neednt decide yet whether to study arts or science.
你现在不必决定学习文科还是理科。
He couldnt remember whether to turn left or right.
他没记住向左拐还是向右拐。
C ask,decide,forget,learn,remember 等词后也可以直接跟不定式。但其含义并不一定相同。
learn how+不定式(=acquire a skill学会技能):
She learnt how to make lace.
她学会了怎样做花边。
如果是相当普通的技能,通常就不用how:
She learnt to drive a car.
她学会了开汽车。
learn+不定式(不带how)可以有另一种含义:
She learnt to trust nobody.
她信不过任何人。相当于:
She found from experience that it was better to trust nobody.
经验告诉她,谁都不可靠。
同时注意:
I decided to do it.
我决定要做这件事。相当于:
I said to myself,Ill do it.
我心里想:我要做这件事。
