解答：

一般過去時態(tài)用法：定義：表示過去某一時間所發(fā)生的動作或存在的狀態(tài).動詞過去式的構(gòu)成： 　　a.規(guī)則動詞過去式的變化可速記為"直"、"去"、"雙"、"改"四字訣.　?、僖话闱闆r下在動詞原形后直接加-ed.如：entered, finished, wanted,played.　?、谝圆话l(fā)音的字母e結(jié)尾的動詞,去掉e再加-ed.如：liked, joked, hoped,lived.　　③重讀閉音節(jié)單詞需雙寫最后一個輔音字母再加-ed.如：stopped, planned, stopped,nodded.　?、芤暂o音字母+y結(jié)尾的動詞變y為i,再加-ed.如：carried, studied,tried, worried.　　規(guī)則動詞過去式的讀音也有規(guī)律可循.請記住：清后[t],元濁[d],[t] [d]之后讀[id].　?、偾遢o音[p] [k] [f] [s] [F] [tF]等后,ed要讀[t].如：worked,finished,helped, fetched　?、谠艋驖彷o音[b] [g] [v] [z] [m]等后,ed要讀[d].如：stayed,called,believed,referred　　③[t]或[d]后,ed讀[id].如：started,wanted, permitted, needed. b.不規(guī)則動詞.大多數(shù)動詞的過去式都是由動詞原形加-ed構(gòu)成,這類動詞叫做規(guī)則動詞.但有一些動詞卻不是以加-ed的方式構(gòu)成,這類動詞叫做不規(guī)則動詞.例如: am (是) --was, is（是）--was, are（是）--were, begin（開始）--began, bring（拿來）--brought, can（能）--could, catch（捉?。?-caught, come（來）--came, cut（砍,割）--cut, dig（挖,掘）--dug, do（做,干）--did, draw（畫畫,拉）--drew—等 詳細(xì)請參閱： http://1.com/d/uploads2/2020-10/17/gorghq51zyx.html 1）經(jīng)常與yesterday（昨天）, last week（上周）, last month（上個月）, last year（去年）, two months ago（兩個月前）, the day before yesterday（前天）,in 2000 (在2000年), in those days （在那些日子里）等表示過去的時間狀語連用.如： I was born in 1990. 我出生在1990年.I went to the park last week. 我是上周去的公園.I stayed there for two months.我在那里呆了兩個月了.When did you go to the park? 你是什么時候去的公園.A:We could have walked to the station; it was so near.我們本來可以步行去車站.車站離這很近.B:Yes.
