Grammar Focus
How long have you had that bike over there? I've had it for three years.
How long has his son owned the train and railway set? He’s owned it since his fourth birthday.
Have you ever played football? Yes, I did when I was little, but I haven't played for a while now.
含有for，since的现在完成时的用法歌诀: 过去的动作或状态，一直持续到现在，for、since 把时间带。
for+时间段
since
时间段+ago
过去的时间点
过去时的从句
现在完成时表示动作或状态在过去已经开始，持续到现在可能还要持续下去，常和for, since引导的表示一段时间的时间状语连用，谓语动词多用延续性动词。
如：live, teach, learn, work, study, be open, be closed, keep, have, be away, be married, be asleep, be ill等。

Grammar
现在完成时的持续型用法
动词：?延续性动词：表示能够延续的动作；表示经过和 经历；常与for+一段时间，since+时间点连用。
eg：He has lived here for 6 years.
?非延续性动词：表示不能延续的动作，这种动作发生后立即结束；表示行为的结果。在肯定句中不能和表示时间段的状语连用；在否定句中则可以。
eg：I have left here for 3 years. ×
I haven't left here for 3 years. √
谓语动词用延续性动词，可以用how long提问。
