1.一般过去时表示过去发生的事，动词用过去式：

How long did you stay there?

2.过去式有两类，一类为规则动词，它们的过去式都以现在式加-ed词尾构成，一般情况下直接加-ed，如work—worked, want—wanted。原词若以字母e结尾，则只加一d，如live-lived, free-freed，以“辅音+Y”结尾的词，变y为i，再加-ed：cry-cried, marry-married，以重读闭音节结尾，末尾又只有一个辅音字母者，将该字母双写再加-ed: plan-planned, permit-permitted。另一类为不规则动词，如do-did, go-went, see-saw, have-had。
