今天总结的八种时态是大家在初中阶段必学必考的,期末复习时一定要加倍重视哦!(温馨提示:不要忘记收藏哦,用时好找)。 英语八大时态: 1一般现在时标志:动词原形 1. 表示经常性或习惯性动作,常与表频度的时间状语连用: She often speaks English. I leave home for school at 7 every morning.2. 表示现在的状态、特征、职业、能力、感觉等: He seems to feel a bit down today. He works as a driver.3. 表示真理、客观存在、科学事实或用于格言警句中: Shanghai lies in the east of China. Columbus proved that the earth is round. Where there is a will, there is a way.4. 表示现在瞬间的动作: Here comes the bus!5. 表示将来1) 表按规定、计划、安排将要发生的动作(仅限于某些表示“来、去、动、停、开始、结束、继续”等的趋向动词),可以与表示未来的时间状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通状况。如: The next train leaves at 3 o’clock this afternoon. How often does the shuttle bus run?2) 在时间和条件状语从句中常使用一般现在时表示将来发生的事情: When Bill comes (不用will come), ask him to wait for me. I shall go there tomorrow unless I’m too busy.2一般过去时标志:动词过去式*闭音节:元音字母a, e, i, o, u如果发字母本来的音则称为开音节,否则称为闭音节。1. 表示过去某时所发生的动作或存在的状态,常与表示过去的时间状语连用(e.g. yesterday, this morning, just now, a moment ago, in May, last night / year / week, once upon a time, the other day, before …, when …, in the past等)。如: Jim rang you just now. Liu Ying was in America last year.2. 表示过去经常或反复发生的动作,特别是used to do表达的句型,本身表示的就是过去常常。如: When I was a kid, I often played football in the street. She used to visit her mother once a week.*注意区分sb. used to do sth.(某人过去常常做某事,此处to是动词不定式标志符号)和sb. be used to sth./doing sth.(某人习惯于某物/做某事,此处to是介词)。3. 代替一般现在时,表示一种婉转、客气、礼貌、商量的语气。此用法仅适用于少数动词(如want, hope, wonder, think, intend等)及情态动词could, would。如: I wondered if you could have a word with me. I hoped you could help me with my English. Would you mind my sitting here?
