1第七讲一般现在时/一般过去时 【学习目标】对初一，初二所学过的几种时态进行系统复习，并通过反复地讲解和练习，对每种时态可以做到灵活运用。本讲重点讲解一般现在时和一般过去时。【知识要点】一般现在时一.一般现在时使用情境:1.经常发生或反复发生的动作或是习惯。e.g I like making snowmen in winter.Do you often wash your hair?2.永恒的真理。e.g The sun rises in the east and sets in the west.A timely snow promises a good harvest.3.条件状语从句中从句一般现在时表将来。例如：if it doesnt rain tomorrow ,our school will hold a sports meeting.二一般现在时的标志词：always. usually. often. sometimes. every day. every weeke.g He always goes to bed at ten at night.She often gets up late on Sundays.三谓语构成：1.当主语是第三人称单数时，谓语动词要加-s 或-es例如：she takes a subway to go to work on weekdays.动词的单三形式变化规则:2. 当主语是其他人称时，谓语动词要用原形。You always help me and I feel grateful to you .一般过去时的构成及用法一、定义： 表示在过去的某个时间里所发生的动作或存在的状态。时间状语有：yesterday, last week, an hour ago, in 1982 等。21）I was at the zoo yesterday. 昨天我在动物园。2）I went to bed at eleven last night . 昨晚我 11：00 睡觉。2表示在过去一段时间内，经常性或习惯性的动作。1）When I was a child, I often played football in the street.我在小的时候，我经常在街道上踢足球。2）My father often drove to work last year. 去年，我爸爸经常开车上班。二、句子结构1在表示某个时间里存在的状态的句子，系动词用过式 was，were 构成。如：（1）I was at home yesterday.昨天我在家。2在表示过去某个时间里发生的动作，用动词的过去式构成。如：I visited my uncle yesterday. 昨天我拜访了我的叔叔。 规则变化：(1) 在词尾加 ed 或 d英语中大部分动词过去式都是规则变化的，即在动词后加上 ed；如果结尾字母是不发音的 e，则只要加上一个 d 就行了。例如：work-worked clean-cleaned play-playeddecide-decided live-lived love-loved (2) 以辅音字母+y 结尾的，变 y 为 i 加 edstudy-studied hurry-hurried carry-carried (3) 以重读闭音节结尾的，双写最后的辅音字母再加 edstop-stopped drop-dropped wag-wagged 2.不规则变化的动词过去式不规则变化是指过去式不能加 ed，用另外一个词来表示。这样的不规则过去式也有很多，只有靠一个一个去记忆了。例如：is/am-was are-were have/has-hadshall-should will-would can-could may- might go-went come-came take-took sit-sat say-said get-got swim-swam run-ran write-wrote sing-sang tell-told speak-spoke begin-began break-broke 【经典练习】一、用实义动词的正确形式填空31.
