第三章 時態(tài) 一般過去時

　　1.一般過去時表示過去發(fā)生的事，動詞用過去式：

　　Where were you yesterday?

　　你昨天去哪里去了?

　　How long did you stay there?

　　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.過去式有兩類，一類為規(guī)則動詞，它們的過去式都以現(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，末尾又只有一個輔音字母者，將該字母雙寫再加-ed: plan-planned, permit-permitted。另一類為不規(guī)則動詞，如do-did, go-went, see-saw, have-had。
