574　recognize和know from

① recognize是及物動詞。

I recognized him without difficulty. 我毫不費力地認出了他。

She has changed so much that I can hardly recognize her. 她變化那么大，我?guī)缀跽J不出來了。

（2）表示“認可，承認（government，country，theory），認識到”，結(jié)構(gòu)為：

recognize sth.

recognize sb. to be

recognize sb. as

recognize+that從句

They don't recognize the new government. 他們不承認新政府。

I recognize her to be cleverer than I am. 我承認她比我聰明。

They recognized him as the best student in the class. 他們承認他是班上最好的學(xué)生。

He recognized that he had made mistakes. 他承認他犯了錯誤。

We recognized that we have to overcome many difficulties. 我們認識到必須克服許多困難。

提示

recognize表示“認出（熟悉的人或物），認識到（某種價值、合法性、真實性）”，為非延續(xù)性動詞；而know則表示“認識”，為延續(xù)性動詞。比較：

我認識他多年了。

I have recognized him for many years.

I have known him for many years.

② know…from表示“認出，區(qū)分，辨認”。

They are twins and it's almost impossible to know one from the other. 他們是雙胞胎，要分清他們倆幾乎是不可能的。
