【第1篇 小學英語語法總結(jié)：過去完成時
1 、過去完成時是一個相對時態(tài)，表示過去的過去，只有在兩個過去發(fā)生的動作相比較時才可顯示出來。
e.g. as soon as we got to the station, the train had left.
注：主從句表達的動作緊接時，即兩動作發(fā)生的時間沒有明顯時間上的懸殊或空檔時，主從句都可用一般過去時。
e.g. where did your brother study before he joined the army?
2 、過去完成時可表示截止過去某一時間動作的總或動作的結(jié)束。
e.g. by the end of last month. we had reviewed four books
by eight o`clock, he had finished his homework.
與這個時態(tài)連用的時間狀語常有：
by 1985, by eight o`clock, by then, by the end of last month, by the time when, when, as soon as, before 等連詞引導的時間狀語從句，表示主句動作結(jié)束的時間。
