I thought her nice and honest the first time I met her.为什么用“the first time”而不用“for the first time”或用"by the first time”

问题描述:

I thought her nice and honest the first time I met her.
为什么用“the first time”而不用“for the first time”或用"by the first time”

the first time I met her = when I first met her
for the first time 生平头一遭
by the first time 直到第一次
前面有for,by 时,整个意思变了。

固定用法!

for the first time 是副词词组,后面不能加句子,the first time 后可以加句子
