1. How long have you had that bike over there? I’ve had it for three years. 2. How long has his son owned the train and railway set? He’s owned it since his fourth birthday. 3. Have you ever played football? Yes, I did when I was little, but I haven’t played for a while now.

表示从过去已经开始持续到现在的动作 或状态,可以和表示“从过去某一时刻 延续到现在的一段时间状语”连用,如 “for+时间段”、“since+过去时间 点”、“since+过去时的从句”、 “since+一段时间+ago”。且for与since 引导的时间状语可以相互转换。

e.g. My uncle has worked at this factory for ten years. = My uncle has worked at this factory since ten year ago. I’ve lived here since 1990. 自从1990年以来我就住在这里。 I haven’t seen him for three years. 我三年没有看见他了。

She’s been at this school since five years ago. 自从五年前以来她就在这个学校。
