非延续性动词不能与时间段连用

非①延续性动词不能与时间段连用： go/come/begin/start/die/buy/borrow/sell/leave/arrive/ receive/become等词语是瞬间动词示的动作是一时的，不能延续，不能与for、since等表示一段时间的词连用，也不能用于how long引导的疑问句中。 如不能说：He has borrowed the book for two months.(ⅹ) 但可以说：He has kept the book for 2 months. 或：It has been 2 months since he borrowed the book. 或：Two months has passed since he borrowed the book. 这些瞬间动词常与它对应的可以表示时间段的词语进行互换。 become—be                  borrow—keep      buy—have begin (start)—be on    open—be open      die—be dead  leave--be away            come--be here/in    go out—be out join--be a member/be in    begin to study--study 注明：非延续性动词在否定结构中可用于现在完成时态：I haven’t bought anything for two days.
