It's three months since I lived here .
我翻译:我住在这三个月了.
书上翻译:我不住在这儿三个月了.
那里可以看出否定来?
这个是It is + 时间段 + since的用法.
如果since后面是持续性的动作,就按否定翻译.
Since从句中的谓语动词是短暂性动词:用一般过去时或现在完成时,意义一样,都表示过去时间的起点:
It is three years since I saw Bill.
It has been three years since I saw Bill.
It is three years since I have seen Bill.
句意是:从我那时看见Bill到现在已经三年了.
Since 从句中的谓语动词是延续性动词或状态动词,过去时态表示动作或状态的结束,现在完成时表示动作或状态的开始并延续至今:
I haven’t heard from him since he lived in London.
(他已不在London,从他离开London之时起到现在我就没有收到过他的来信)
I haven’t heard from him since he has lived in London.
(他还在London,从他搬到London起到现在我就没有收到过他的来信)
They have had three headmasters since I was at this school.
(我已不在这所学校,从我离开这所学校他们已经换了三位校长)
They have had three headmasters since I have been at this school.
(我还在这所学校,从我到这所学校起他们已经换了三位校长)
