下面句子中的recognize用得对吗？
He didnt recognize how silly he was when he said that.
请问句中的recognize是不是是realize之误？
▲第一要说明的是，你的句子中的 recognize 并不是是 realize 之误。
没错，表示意识到认识到，英语一般用realize / realise 来表示。如：
I realized wewere still worlds apart. 我意识到大家的观念仍旧有天壤之别。
I realised Iwas looking at it from the wrong angle. 我意识到当时考虑他的角度不对。
She realizedthat the pain of her loss had never truly healed. 她意识到失败的痛苦从未真的消除。
Several years went by before I realizedthat David had lied to me. 过了几年我才意识到戴维对我撒了谎。
▲但，recognize 有时也可以用来表示 realize 的意思，譬如《牛津高阶英汉双解词典》的 recognize 词条的第3条释义就是：be prepared to admit or be aware of ; realize（承认或认清某事物；认识到）。
▲如下面一句摘自《剑桥高级英语词典》：
It is important to recognize how little we know aboutthis disease. 当我意识到还没为考试做任何筹备时，立刻回到了日常。
▲请再看下面两个高考考试题中的句子句子结构高度相似，但一个用了realize，一个用了recognize：
The shocking news made me realize what terrible problems we would face. 那个让人震撼的新闻让大家意识到，大家将要面对多么可怕的问题。
I was surprised by her words, which made me recognizewhat silly mistakes I had made. 我对她的话感到震撼，这使我意识到我有多愚蠢的错误。
