at the first time 和 for the first time的区别
1、the first time之后接一个定语从句，用that，when引导均可，或者干脆省略。
I retired the first time when he was the coach.
I retired the first time that he was the coach.
I retired the first time he was the coach.
【翻译】我在他初次当教练时退的休。
2、for the first time是个介词词组，意为“第一次，首次，初次”，一般用作状语，修饰动词。
She met him at the cinema for the first time. 她第一次碰到他是在电影院里。
I took an airplane for the first time in my life. 我有生以来第一次搭飞机。
3、以下句子反映出两个词组的差别，两句话的意思相同。
Mary was a shy girl the first time (that/when) I met her. （the first time用作连词）
Mary was a shy girl when I met her for the first time.（for the first time用作状语，修饰met）
