It's four years since Mike ____ to Tibet.A.has been B.is coming C.will come D.came
为什么不是A呢
句型:
It is +一段时间+since...意思是“自.发生以来已经一段时间了”.后边用一般过去时
如:
it is three years since he died.(自)他去世以来已经三年了.
而你的A属于另外一种
即:since 引导的从句,主句用现在完成时,从句用一般过去时!从句就是since后边的句子.
如:
He has studied very hard since he came to our school.
自从他来到我们学校,他学习就非常努力.
注意这个和:He has been a teacher since 1999.仔细观察哦,这个是简单句
D
since 后用一般过去时。
希望能帮到你,祝你开心。
这是固定句式,It's XX years since +一般过去式
你好:
D.came
全翻译:自从麦克来到台北,已经四年了。
Since sb. did ...这里本身就决定了是过去式哦
希望我的回答对您有帮助,祝好!
现在完成时的基本结构。 four years has passed since Mike came to Tibet或 Mike has been in Tibet for four years
通常since后面加表示过去的时间点的句子。
It's half past four.
it's four twenty-three
four years
Four Years
What___is it?It's four thirty.
