I'm practicing with the words 以前 and 以后.
Using the word 以前, I came up with this sentence:
我一分钟以前刚刚看到他!
My English intention was to make this sentence:
I just saw him a minute ago!
I was told the format of using this word with time words was this:
time word + 以前 + following action
So to break up the sentence I made:
[我]一分钟 + 以前 + 刚刚看到他
I'm not sure if 刚刚
is actually separate from 以前
.
