她小时候母亲就去世了。
不可说:Her mother has died since she was a child.
③Since前不可加表示时间的词语,但可以与ago连用。
例如:
She has lived with us since her mother died three years ago.
自从她母亲3年前去世,她就一直和我们住在一起。
不可说:She has lived with us three years since her mother died.
④在It was five years ago since his father died. 一句中的since用错了,因为在含有ago的时间范畴里,已经有了从过去的一个时间点以来的时间,即已有了since的时间范畴,所以再用since是多余的。
改为:
It was five years ago that his father died.
他父亲5年前去世了。
It is five years since his father died.
他父亲去世已经5年了。
