Discussion time 1:关于since与for的区别与用法
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.
共同点:常用于现在完成时态(动词使用延续性动词)提问用How long
不同点：1)for+一段时间，表示“持续了…”
2)since+ 过去时间点，表示“自从...”
3)Since +...ago
4)since+ 过去时态句子
用since和for填空
