英语,初三
Ten years______since my uncle ________to america
Apassed:went B has passed:went
Cpassed:has gone D has passed;has gone
请解释一下为什么不选c而选b 拜谢
还是不懂吖since的那种用法吖？

首先是since的用法
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).
I have been here since 1989.
2) since +一段时间+ ago
I have been here since five months ago.
3) since +从句
Great changes have taken place since you left.
Considerable time has elapsed since we have been here.
4) It is +一段时间+ since从句
It is two years since I became a postgraduate student.
其次是时态搭配问题
现在完成时可以用来表示发生在过去某一时刻的,持续到现在的情况,常与for,since连用.
从句since my uncle went to amercia是作为过去某一时刻,时态用一般过去时.
从叔叔去美国这一点开始,到现在已经有十年了.时态用现在完成时态.
