2)過(guò)去時(shí)常與具體的時(shí)間狀語(yǔ)連用,而現(xiàn)在完成時(shí)通常與模糊的時(shí)間狀語(yǔ)連用,或無(wú)時(shí)間狀語(yǔ)。
一般過(guò)去時(shí)的時(shí)間狀語(yǔ):

過(guò)去時(shí)常用的非持續(xù)性動(dòng)詞有come, go, leave, start, die, finish, become, get married等。
舉例:
I saw this film yesterday.(強(qiáng)調(diào)看的動(dòng)作發(fā)生過(guò)了。)
I have seen this film. (強(qiáng)調(diào)對(duì)現(xiàn)在的影響,電影的內(nèi)容已經(jīng)知道了。)
