from then on是什么时态的标志?
from then on是过去时态的标志。它通常用于描述某个事件或情况从过去的某个时间点开始,并一直持续到现在。
from then on的用法
from then on通常与过去完成时或现在完成时连用,表示某个动作或状态在过去的某个时间点之前已经完成,但对现在仍然有影响。例如:
- From then on, I have never seen him again.(从那时起,我再也没有见过他。)
- From then on, he has become a very successful businessman.(从那时起,他已经成为了一名非常成功的商人。)

from then on的易错点
from then on与since then的区别:from then on表示从过去的某个时间点开始,一直持续到现在;since then表示从过去的某个时间点开始,一直持续到现在,并且这个动作或状态对现在仍然有影响。例如:
