2022年中考九年级英语语法---一般过去时全解

2022年九年级中考英语语法讲解一般过去时的结构一、构成方法一般过去时用动词的过去式构成，即在动词原形后加ed。 二、用法说明1、表示在过去某个时间所发生的动作或所处的状态。常与yesterday, last week, in 1989, just now, a moment ago, the other day等连用。如：He was here just now. 他刚才还在这里。What did you do yesterday? 你昨天做了什么事?2、在过去一段时间内的经常性或习惯性动作。如：We often played together when we were children. 我们小时候常在一起玩。注：表示过去经常发生的动作还可用used to 和would。如：He used to smoke a lot, but he doesn't now. 他过去经常抽烟，但现在不抽了。Whenever we were in trouble, he would help us. 每当我们遇到困难，他都会帮助我们。3、表示主语过去的特征或性格。如：At that time she was very good at English. 那时她英语学得很好。4、用在状语从句中表示过去将来。如：He said he would wait until they came back.5、一般过去时有时可以表示现在，多与 want, hope, wonder, think, intend 等动词连用，使语气更委婉。如：I wondered if you could help me. 不知你能不能帮我一下。6、有时用一般过去时也是时态一致的需要。如：I didn't know you were here. 没想到你在这里。 注意：1. 表示一系列的动作，尽管有先后，都用一般过去时，最后两个动词之间用and连结。如：He opened the door, rushed out and then disappeared. 他打开门，冲了出去，然后就消失了。2. 注意在语境中理解“我刚才/原来还不……”。如：—Your phone number again? I didn't quite catch it. —It's 2566666. 请再说一次你的电话号码，好吗?我刚才没听清楚。是2566666。动词的一般过去式肯定形式主语+动词过去式+其它例句：She came to help us in those days．否定形态主语+didn't +谓语动词原形+其它1.在行为动词前加didn't，同时还原行为动词例句：I didn't know you like coffee.一般疑问句①Did+主语+谓语动词原形+其它②Was/Were+主语+表语例句：Did you do homework?特殊疑问句①特殊疑问词+ did+主语+动词原形+其它？②特殊疑问词+was/were+物主代词/...'s+sth.？被动语态主语 + was / were + 动词的过去分词用表格整理如下：一般过去时的时间状语yesterday (morning,afternoon,evening)the day before yesterdaylast night (week,Sunday,weekend,month,winter,year,century 世纪）agothis morning/afternoon/eveningwhen引导的状语从句（动词过去时）just nowthe other day -- a few days ago.at the age of 10 （过去年龄段）in the old daysat that timein the+整十数年份+s（⋯世纪⋯年代）used to do... （过去做...）一般过去时的句型运用Be 动词Be 动词的一般过去时态.在没有实义动词的句子中使用be动词， am/is 的过去式为was; are的过去式为were.构成：肯定句：主语+was (were) +表语如：I was late yesterday. （昨天我迟到了。）否定句：主语+was (were) +not+表语如：We weren't late yesterday. （我们昨天没有迟到）【注意】：当句中含有系动词was，were时，可直接在其后加not构成否定句。如：I was on the Internetwhen you called me.当你打电话给我时，我在上网。→ ：I was not/wasn't on the Internet when you called me .当你打电话给我时，我不在上网。疑问句：Was (Were) +主语+表语当谓语动词提前并直接或间接表达注意时态特殊疑问句：特殊疑问词+was (were) +主语+表语实义动词实义动词的一般过去时态肯定句要使用动词的过去式，否定句和疑问句要使用助动词do和does 的过去式did.否定句：主语+didn't +动词原形+宾语疑问句：Did +主语+动词原形+宾语助动词和情态动词助动词和情态动词过去式如下：shall―should（将要）用于第一人称单数will―would（将要）用于所有人称can—could（能，会） may―might（可以） must―must （必须）have to―had to（不得不）助动词和情态动词的过去时态要使用他们的过去式，后面的动词还使用原形。如：I had to do my homework yesterday. （昨天我不得不做作业。）一般过去时的句型变化一变：肯定句变为否定句　【技巧1】当句中含有情态动词或助动词could，would，should等时，可直接在其后面加not构成否定句。例如：　I could get you a concert ticket. → I could not / couldn't get you a concert ticket.　【技巧2】当句中含有系动词was，were 时，可直接在其后加not构成否定句。例如：　I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me.　【技巧3】当句中谓语是除情态动词、助动词、系动词was,were以外的动词时，在该动词之前加did not / didn't，动词还原，构成否定句。例如：　The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.二变：陈述句变为一般疑问句　【技巧1】移动词语的位置。将was，were,could，would，should等移到句首。例如：　He could pack his things himself. → Could he pack his things himself?　【技巧2】添加助动词did。谓语是除情态动词、助动词、系动词was,were以外的动词时，在主语之前加did，动词还原。例如：　Mr Li looked very old. → Did Mr Li look very old?三变：陈述句变为特殊疑问句　【技巧1】确定疑问词：人who / whom，物what，地点where，时间when / what time，原因why，频率how often，长度how long，距离how far等等。例如：　They gave the concert last night. → When did they give the concert?　【技巧2】辨认结构形式：疑问词+情态动词/助动词/ was / were / did +主语+...? 例如：　The accident happened near the station. → Where did the accident happen情况方法示例一般情况+edwork—— workedlook——looked以不发音的e(哑e)结尾+dlive ——livedhope——hopedlike——liked以辅音字母+y结尾把y变i+edstudy—— studiedcarry——carried以重读闭音节结尾且末尾只有一个辅音字母(重读辅元辅)双写尾字母+edstop—— stoppedplan——planned以ic结尾+kedpicnic——picnickedtraffic——trafficked特殊情况不规则变化are---wereis/am---wasdo---dideat——atego——went等等肯定式疑问式否定式疑问否定式I workedDid I work?I didn't workDid I not work?He(She,It) workedDid he(she,it) work?He (she,it)didn't workDid he(she,it)not work?We workedDid we work?We didn't workDid we not work?You workedDid you work?You didn't workDid you not work?They workedDid they work?They didn't workDid they not work?
