Unlikeadults,childrenarenormallynotawareoftheconsequencesofbad behaviour, and setting rules can help them realise(动 + 宾 + 宾补)how to behave in a socially acceptable way.(realise 的宾语)
注意两种不一样的结构:
how to behave in a socially acceptable way (名词定义)
to behave in a socially acceptable way (非谓语定义)
以上两个表达,是两个不一样的定义,括号里已标出。除此之外,其语法用途也不相同。比较:
He teaches ushow to behave in a socially acceptable way.(直接宾语。体现名词性质)
He teaches us to behave in a socially acceptable way. (宾语补足语。动词不定式)
由此可以得出如此的结论:在不定式之前加 wh-word疑问词,即:wh-word to do,不可以再称作不定式,这个时候,它实质上已经蜕变为一个“名词词组”(由名词性从句省略而来)。所以,He teaches ushow to behave in a socially acceptable way. 其结构为: teach sb. sth.
