英语的过去式 有哪些
英语的过去式 有哪些
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:
  (1)一般情况下,动词词尾加 ed ,如:
  work—worked; play—played;want— wanted; act—acted
  (2)以不发音的 e 结尾动词,动词词尾加 d,如:
  live—lived; move—moved; decide—decided; decline—declined; hope—hoped;
  (3)以辅音字母 + y结尾的动词,把y变为i 再加ed,如:
  studied tried copied justified cried carried embodied emptied
  (4)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,如:
  stopped begged fretted dragged dropped planned dotted dripped
  (5)注: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 ,is/am-was,are-were ,see-saw,bring-brought,do-did,teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent, eat-ate,give-gave,sit-sat,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,
  put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam,sweep—swept,sing—sang,draw—drew,
  以上的(1)至(4)条中的发音均有改变,具体分别有/d/ /t/ /id/.
  而不规则动词的过去式的发音则略有不同,但是有些还是按照一定规律变化的.如以上的:make - made,get - got ,buy - bought ,come - came ,fly-flew ,bring-brought,teach-taught, think-thought, say-said,sit-sat. read-read, spend-spent,give-gave,tell-told,write-wrote,feel-felt,find-found,hear-heard,know-knew,put-put,grow-grew,take-took,catch-caught,come-came,become-became,swim-swam,sweep—swept,sing—sang,draw—drew.
  仔细看一看,能发现它们的一些变化规律,也就是说不需要死记硬背这些过去式,知道了原型和变化规律,就可以写出来了.有的变化部分读音也是有规律的.分类记忆是对学习过去式很有帮助的!

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 yesterday, the day before last, last week, two days ago 等,上下文清楚时可以不带时间状语. I worked in that factory last year. 去年我在那一家工厂工作. I went to the Tian Long Mountain yesterday. 昨天我们去了天龙山.
  一般过去时的用法一.概念:一般过去时是表示在过去的时间里发生的动作或状态,通常与表示过去的时间状语连用.
  二.时间状语:yesterday, the day before yesterday, two days ago, long long ago,a minute ago,last year(week, month), just now, at that time, in those days.
  三.过去时的用法:1.有确定的过去时间状语时要用过去式.
  例:We had a good time last week.
  2.表示过去连续发生的动作时,要用过去式.
  例:The boy closed the door, turned off the window, and then went to bed.
  3. 表示过去一段时间内经常或反复的动作,要用过去式.
  例:She often came to help me at that time.
  四.一般过去式的构成形式:☆Be动词的过去式: (1)肯定句:主语+ be动词的过去式(was, were)
  例:He was ill yesterday. She was nine two years ago.They were my students long long ago.
  (2)否定句:主语+ be动词的过去式(was, were)+ not
  例:He was not ill yesterday.She was not nine two years ago.They were not my students long long ago.
  (3)一般疑问句:直接把be动词提到句首.
  例:Was he ill yesterday?
  肯定回答:Yes, he was.
  否定回答:No, he wasn't.Was she nine two years ago? Yes, she was. / No, she wasn't.Were they your students long long ago? Yes, they were. / No, they weren't.
  ☆实意动词的过去式:(1)肯定句:主语+动词的过去式
  例:He played football last week.She watched TV last night.
  (2)否定句:主语+ did not +动词原形
  例:He did not play football last week.She didn’t watch TV last night.
  (3)一般疑问句:Did +主语+动词原形 例:Did he play football last week?
  回答:Yes, he did./ No, he didn't.
  Did she watch TV last night?
  回答:Yes, she did. / No, she didn’t.
  五.动词变过去式的几种常用规则:1.一般动词直接+ ed;
  例:look--looked want--wanted listen --listened
  2.以e结尾的词直接+ d;例:live--lived phone--phoned
  3.以辅音字母加y结尾, 变y为i加ed;例:try--tried study--studied
  4.重读闭音节结尾的,词尾只有一个辅音字母,双写词尾辅音字母+ ed;例:stop--stopped plan--planned
  5.不规则动词: 动词由原形转变为过去式时不按词尾加“-ed”之变化规则者叫做不规则动词.小学常见的动词不规则过去式如:是be/is/am/are- was, 是are- were, 来come-came, 去go- went, 有have- had, 做/干do- did, 做make- made 读read- read, 放put- put, 切割cut- cut,写write- wrote, 带走take- took, 买buy- bought, 带来bring- brought,想think- thought, 看见see- saw, 说say- said, 说话speak- spoke,打破break- broke, 得到get- got, 跑run- ran, 告诉tell- told,唱sing- sang, 喝drink- drank, 吃eat- ate, 游泳swim- swam,开始begin- began, 偷steal- stole, 遇见meet- met, 卖sell- sold, 坐sit- sat,跑run-ran,读read-read,想要want-want,知道know/known,fall-fell等等

  在上面的句子中第一句属于be动词的一般过去时态;
  第二句和第三句属于实义动词go的一般过去时态.
