not···anything=nothingHe should't eat anything.=He should eat nothing.

问题描述:

not···anything=nothing
He should't eat anything.=He should eat nothing.

他不应该再吃了。
He should't eat anything.=He should eat nothing.
否定形式时,可以用否定意义的词来代替。

He should't eat anything.意思是:他不应当吃任何东西.
He should eat nothing.意思是:他不应当吃任何东西.
第一句是否定谓语动词的;第二句是通过否定宾语,即nothing是否定意义的,达到了同样的效果.
