for the first time第一次, 是一个表时间的介词短语,在句子中做时间状语,常用于完成时。如:
They have met each other for the first time.他们是第一次见面。
the first time 第一次, 此结构是:the +序数词+time, 相当于一个从属连词,引导时间状语从句。 第几次...
I loved him the first time I saw him. 我第一次见他时就喜欢上他了。
at first , 一开始时,最初时。介词短语做状语
I couldn't understand the meaning at first, but now i can make sense of it with his help.
it/that was the first time that +从句(主语+had done)那是第一次...
it/this/that is the first time that +从句(主语+has/have done)这是第一次...
That was the first time that we had met each other.
this/it is the first time that we have met each other.
此结构为 it/this is the +序数词+time that 从句(主语+has/have done)
it/that/was the 序数词+time that 从句(主语+had done)
这两种结构时态是固定的。
