有这样一句:You have to know how to study. 好像固定搭配应该是 how to do it 和What to do 吧!为什么此句省略了study 的宾语?或是因为此时study为不及物吗?
你认为“好像固定搭配应该是 how to do it 和Whatto do”是一种错觉!同意黎老师的说法,此处的 study 是不及物动词,这里的how to study意思是“如何学习”。又如:
Do you know how to type? 你会打字吗?
Do you know how to knit? 你会织毛活儿吗?
He didn’t know how to begin. 他不知从何说起。
You are supposed to know how todrive. 你应该会开车。
比较:
You have to know how to study. 你得知道如何学习。
You have to know what to study. 你得知道学习什么。
