2、以用来表示发生在过去某一时刻的,持续到现在的情况,常与for（+时间段）,since（+时间点）连用. Mary has been ill for three days. I have lived here since 1998. 注意（超级重要!）：瞬间动词（buy,die,join,lose 等）在肯定句中不能for/since 连用。要改变动词:1.have 代替 buy My brother has had this bike for almost four years. 2、用 keep或 have代替 borrow I have kept the book for quite a
