英语-请问这为什么用having heard?
When listening to the teacher,one of the students just interrupts the teacher and says " No offense,but by the time we're in the job market,won't that stuff be outdated?" Having heard this question,the teacher stops demonstrating the Multiplication Table and seems to be quite shocked and embarrassed.

Answer 1

那是the teacher发出的动作,而且是在听到问题之后,老师才发出主句所说的内容,有时间先后,所以用主动的完成时态having heared
