since的四种用法(***)
1)since +过去一个时间点(如具体的年、月、日期、钟点、1980, last month, half past six)。例如:
I have been here since 1989. 1989起,我一直在这儿。
2)since +一段时间+ ago。例如:
I have been here since five months ago. 我在这儿,已经有五个月了。
3)since +从句。例如:
Great changes have taken place since you left. 你走后,变化可大了。
Great changes have taken place since we were here. 我们走后,变化可大了。
4)It is +一段时间+ since从句。例如:
It is two years since I became a postgraate student. 我考上研究生有两年了。
