　 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):

yesterday, last week，…ago, in1980, in October, just now, 具體的時(shí)間狀語(yǔ)

共同的時(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.

　�。◤�(qiáng)調(diào)看的動(dòng)作發(fā)生過(guò)了。）

　　( 三年前入團(tuán)，joined為短暫行為。)

　 句子中如有過(guò)去時(shí)的時(shí)間副詞（如 yesterday, last, week, in 1960）時(shí)，不能使用現(xiàn)在完成時(shí)，要用過(guò)去時(shí)。
