对于这种题型偶也很头痛的!!!这是since用法问题吧.It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法,后者是口语说法。用was的是It was +段时间+since+主语+had done.
It is five years since he left here.他已经离开这儿五年了。
It was five years since he left here.
。。。。。since 一般为固定格式。。 since 引导的是过去时态
B since 是现在完成时的使用标志
如They have finished the project since I was ten.
