You dint work Did you not work? They worked Did they work? They didnt work Did they not work? 一般过去式构成: 表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化如下: 一般情况下,动词词尾加 -ed 。 worked, played, wanted, acted 以不发音的 -e 结尾动词,动词词尾加 -d。 Lived, moved,decided, declined, hoped, judged, raised, wiped 以辅音字母 + y结尾的动词,把-y变为-i 再加-ed。 studied, tried, copied , justified, cried, carried, embodied, emptied 以一个辅音字母结尾的重读闭音节动词,双写词尾辅音字母,再加 -ed。 stopped, begged, fretted, dragged, dropped, planned, dotted, dripped 不规则动词的过去式变化规律性不强,须多加记忆。 go - went, make - made, get - got buy - bought, come - came, fly-flew 其结构是主语+动词的过去式。be动词的过去式为was, were;行为动词的过去式有规则变化和不规则变化两种,规则变化有以下几种情况:1)直接在动词原形末尾加-ed. e.g. work-worked; ask-asked; 2)以e结尾的动词只加-d. e.g. arrive-arrived; like-liked.3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shop-shopped; 4)以辅音字母+y结尾的动词,先把y变成i,再加-ed. e.g. carry-carried; study-studied.有些动词变过去式是不规则的,e.g. fly-flew; break-broke; teach-taught. 这些需要象生单词一样记住. 其句式变化分为两种情况1)含有be动词的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加助动词didnt.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didnt buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday? 一般过去式的用法: 1) 表示过去某一时刻或某一段时间内所发生的动作或情况,通常一般过去式带有表示动作时间状语的词,词组或从句,如:a minute ago, yesterday,last week,in1900,during the night,in those days,the other day(前几天)、once up on a time(过去曾经)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前)、 When I was 8 years old(当我八岁时)等。用一般过去时的时候,要表示“过多少时间之后”一般用after,不用in如: Tom suddenly fel ill yesterday Tom 昨天突然生病了。 She didnt look well when i lat saw her 我上次看见她的时候,她脸色不好 2.一般过去时也可与 today,this week,this month ,this year 等时间状语连用。但是这些时间状语必须指过去,决不包括“现在”在内如: Did you see him today? 今天你见过他了吗? (today实际上指的是今天的过去某一时刻) 3.一般过去时虽不可以与now连用 ,但却可以和just now(刚才)连用。如:He went out just now 他刚出去了 4.一般过去时表示过去的时候还有以下一些情况:用于since从句,主句的谓语动词如果用现在完成时。其后接的since引导的从句一般须用一般过去时如:Its been over a year since i came back from the countryside 我从乡下回来已经一年了(主句的谓语动词 has been 也可以改为 is 但美国英语多用现在完成时) :时间状语可以省略,前面说过一般过去时常与表过去的时间状语连用,但下面一些情况下,时间状语可以省略-从上文可以清楚地看出来时间状语如:Did you sleep well? -前文如有现在完成时所引导时如:I have been within an inch of life ,and didnt know it!-和现在时态对比时候如: He is no longer the man he was-有表示过去习惯的used to 时候如:I used to play football in the street :所表的动作已经完成如:I read a book last week 上星期我读了一本书 : 表示死者的动作和状态。在英语中。说道死去的人的时候,一般用过去时表示 如: Who is the man in the picture? 照片上的人是谁?
