第三章 時(shí)態(tài) 一般過(guò)去時(shí)

　　1.一般過(guò)去時(shí)表示過(guò)去發(fā)生的事，動(dòng)詞用過(guò)去式：

　　Where were you yesterday?

　　你昨天去哪里去了?

　　在那里待了多久?

　　Did you sleep well?

　　你睡得好嗎?

　　The baby cried all night.

　　寶寶哭了一夜。

　　2.過(guò)去式有兩類(lèi)，一類(lèi)為規(guī)則動(dòng)詞，它們的過(guò)去式都以現(xiàn)在式加-ed詞尾構(gòu)成，一般情況下直接加-ed，如work—worked, want—wanted。原詞若以字母e結(jié)尾，則只加一d，如live-lived, free-freed，以“輔音+Y”結(jié)尾的詞，變y為i，再加-ed：cry-cried, marry-married，以重讀閉音節(jié)結(jié)尾，末尾又只有一個(gè)輔音字母者，將該字母雙寫(xiě)再加-ed: plan-planned, permit-permitted。另一類(lèi)為不規(guī)則動(dòng)詞，如do-did, go-went, see-saw, have-had。
