Eg: 肯定句They have lunch at 12. 否定句:They don’t have lunch at 12. 一般疑问句: Do they have lunch at 12. 2第三人称单数作主语,谓语动词变单三;变否定句时,须在动词前加助动词doesn’t; 变一般疑问句时,须在句首○加助动词does Eg: He does morning exercises.→He doesn’t do morning exercises.→Does he often go to school on foot? 一般现在时的时间状语有on Saturdays, in the morning(afternoon, evening),every day, at weekend, how often及一些频率副词often, usually, always, sometimes, seldom, never 等。 动词变单三规则1. 一般情况下,在动词后直接加-s Eg: works, gets, says, reads 2. 以s, x, sh, ch, o结尾,加-es Eg: goes, teaches, washes, does 3. 以“辅音+y” 结尾,变y为i,再加-es Eg: fly-flies, study-studies 4. 不规则变化 have-has 二、一般过去时:表示过去某时发生的动作或情况 (1)过去某个时间所发生的动作或存在的状态 Eg: He was a worker two years ago.

(2) 过去已经开始,一直持续到现在的动作或状态(即它的“未完成用法”)。注意:此时动词可能还要继续 常与for或since引导的时间状语(从句)连用。用how long提问,谓语动词用延续性动词 for+ 时间段 Eg: I lived here for about ten years. since + 时间点 Eg: We have been very busy since 5 years ago. since + 从句(一般过去时) Eg: I have learnt English since I was 5 years old. 短暂性动词变延续性动词,短暂性动词不能与表示一段时间状语连用 begin(start)→be on go there→be there come back→be back come here→be here open→be open close→be closed die→be dead marry→be married finish→be over go to bed → be in bed leave→be away return→be back get out→be out fall asleep→be asleep lose→be lost fall ill→be ill borrow→keep put on→wear/be on become→be get to know→know buy→have(own) receive→have catch a cold→have a cold go to sleep→sleep Eg: He has bought the computer for two years.(误) → He has had the computer for two years. 现在完成时的结构是“have/has+过去分词”。过去分词的变化分规则与不规则两种。规则变化与过去式相同,不规则变化需另记。 它的否定句是在have/has 后加not ,变一般疑问句是把have/has提前。 Eg: I have bought a computer. → I have not bought a computer. → Have you bought a computer? 现在完成时的时间状语通常为already, just, yet, ever, never, before等。” 六、过去进行时 表示过去某一时刻或某一时间内正在进行或发生的动作。可从以下两个方面来理解: (1) 过去某一时刻正在进行或发生的动作。 Eg: They were playing football at ten o’clock yesterday morning. (2) 过去某阶段持续进行的动作。 Eg: We were reading books during the holiday? 另外,在复合句中,若主要动作和背景动作是同时发生的,那么主从句都可用过去进行时 Eg: Jenny was reading while Danny was writing. 过去进行时结构是be动词的过去形式was/were+v-ing, 其句式变化仍然要体现在be上。 Eg: We were having an English lesson in class. → We weren’t having an English lesson in class. →Were you having an English lesson in class? 过去进行时常与过去某一特定时间的状语连用。如at four o’clock last night, at that time, just then, at noon yesterday, this time last Sunday, that time yesterday等。 Eg: What were you doing at nine last night? 有时也没有明显的时间状语,要通过上下文的暗示来确定是否用过去进行时。 Eg: The students all worked hard. Everyone knew what he was working for. 本文来源:https://www.wddqw.com/doc/15f6720529f90242a8956bec0975f46526d3a770.html
