recginze 、know 和 realize三者间的联系与区别

recognize 识别出，认出
know 知道
realize 意识到，领会到

三者就以死上就很不同。recginze指认出某人/某事 、know表示知道 /明白、realize指意识到，认识到/实现。比如 I recginzed him at last. He was my schoolmate.我最后认出他了。他原来是我的校友啊。 I know that he is a wise man.我知道他是一个英明的人。 Does he realize his mistake？他意识到自己的错误了吗？Her dream was finally realized.她的美梦终于成真啦。以上仅为简单的诠释，你明白了吗？

两个词都有“认识、识别”的意思,但在具体用法上又有所差别.

He didn’t realize his mistake until his mother told him.
直到妈妈告诉他,他才认识到自己的错误.
I didn’t realize how late it was.我没有意识到天已经那么晚了.
She realizes now how hard you worked.现在她了解你工作得多辛苦.
When he realized what had happened,he was sorry.
当他明白发生了什么事时,他感到很难过.
2．realize还可以表示“实现；完成”的意思.如：

那个女孩当演员的梦想终于实现了.
3．recognize也可以用作及物动词,表示“认出；辩认；认识”的意思.如：

4．recognize还可以表示“清楚知道；认定”的意思.如：
