Unit8 Once Upon a time过去时和现在时区别讲解与练习 语法精讲:一般过去时与一般现在时的区别 1.概念 一般现在时:表示经常、反复发生的动作或现在的某种状态。 一般过去时:表示过去某个时间或某一段时间内发生的动作或存在的状态;也可表示过去经常或反复发生的动作。 2.搭配的时间状语 一般现在时:always,usually,often,sometimes,every week/day/year,once a week等。 一般过去时:ago,yesterday,the day before yesterday,last week/year/night/month等。 3.基本结构 一般现在时: *肯定形式:①be动词(is,am,are)； ②实义动词(主语是第三人称单数时谓语动词要加-s或-es)。 *否定形式:①am/is/are+not； ②此时态的谓语动词若为实义动词,则在其前加don't,若主语为第三人称单 数,则用doesn't,同时还原实义动词。 *一般疑问句: ①把be动词放于句首； ②用助动词do提问,若主语为第三人称单数,则用does,还原实义动词。 一般过去时: *肯定形式：①be动词的过去式(was/were)；②实义动词的过去式。 *否定形式：①was/were+not；②在实义动词前加didn't，同时还原实义动词。 *一般疑问句: ①was或were放于句首； ②用助动词do的过去式did提问，同时还原实义动词。 4.基本用法 一般现在时: *表示当前时间内经常发生的动作或存在的状态。 *表示主语的特征、性格、能力等。 *陈述客观真理。 *当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。 一般过去时: 主要是用来描述在过去某个时间发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的动作。使用一般过去时，在某种意义上说就是要强调动作或状态发生或存在于过去的某个时候。 课后作业·测评 一、写出下列单词的第三人称单数和过去式形式 2 / 2 学科网（北京）股份有限公司 1. smile__________ __________ 2. ask__________ __________ 3. give __________ __________ 4. answer __________ __________ 5. grow __________ __________ 6. paint __________ __________ 7. say __________ __________ 8. feel __________ __________ 9.walk __________ __________ 10.play __________ __________ 11.stop __________ __________ 12.carry __________ __________ 13.write __________ __________ 14.read __________ __________ 15.teach __________ __________ 16.wash __________ __________ 17.watch __________ __________ 18.go __________ __________ 19.do __________ __________ 20.have __________ __________ 21.eat __________ __________ 22.drink __________ __________ 23.sing __________ __________ 24.dance __________ __________ 25.study __________ __________ 26.fly __________ __________ 27.draw __________ __________ 28.sleep __________ __________ 29.speak __________ __________ 30.take __________ __________ 31.make __________ __________ 23.keep __________ __________ 33.leave __________ __________ 34.open __________ __________ 35.close __________ __________ 36.visit __________ __________ 37.start __________ __________ 38.finish __________ __________ 39.hope __________ __________ 40.plan __________ __________ 二、用所给词的适当形式填空 1.
