理論上often沒有限定時態(tài)吧,但是不太會用在將來時--因?yàn)檫€沒發(fā)生你怎么知道會“often”..
現(xiàn)在時和過去時都可以吧.看你要表達(dá)什么意思了.
過去范疇：
例：我小學(xué)的時候常常玩這個游戲
When I was in primary school,I often played this game.
現(xiàn)在范疇：
例：我常常睡過頭
I often overslept...
同理,完成時也可以
例：最近一周我常常睡過頭
I have often overslept over the past week
或過去完成時
例：上小學(xué)之前我常常玩這個游戲
I had often been playing this game before primary school.
例子比較冷不過希望能說明問題.spend?
