初一五种基本时态讲解及练习上课讲义
初一五种基本时态讲 解及练习
英语语法（时态） 几种简单时态： （1）一般现在时：表示现阶段经常或习惯发生动作或存在的状态，或说明主语特征。 ①一般现在时句子中常有的时间状语：ofte n,usually,sometimes,always,every （day等）,once/twice,a （week等）,on （Sunday 等）,never,in the （morning 等）。 女口：They go to the Palace Museum once a year（他们每年去一次故宫）/ They often discuss bus in ess in the eve ning（他们经常在晚上商谈生意） ②表示客观真理、事实、人的技能或现在状态时句子里一般不用时间状语。 女口：Our teacher said that the earth turns round the sun.（地球绕着太阳转）/ Light travels faster than sound .（光传播比声音快） ③表示十分确定会发生（如安排好的事情）或按照时间表进行的事情，用一般现在 可以表达将来，句子中可以有将来时间。 如: The train for Haikou leaves at 8 : 00 in the morning.（开往海口的列车上午8 点开车） ④在时间状语从句中（以when, after, before, while, until, as soon as等引导）和条件 状语从句中（以if,unless引导），用一般现在时代替一般将来时，句子可以有将来时 间。 女口：Please ring me up as soon as you arrive in Germany（你一至H德国就给我打电话）If it rains tomorrow,we will have to stay at home.（如果明天下雨我们只好呆在家） ⑤一般现在时用于倒装句中可以表示正在发生的动作，动词以come, go为主。 女口：Here comes the bus.（车来了）/ There goes the bell（铃响了）。 （2）一般过去时表示过去某时发生的动作或状态，这种动作或状态可能是一次性，也可能经常发生。 ① 表示过去具体时刻发生的一次性动作时，时间状语有：at （eight）（yesterday morning）, （ten minutes） ago, when弓丨导的时间状语从句。 女口：I got up at 6: 00 this morning.（我是早上六点钟起床的”
初中英语时态讲解练习
初中英语时态综合讲解训练 学习英语时态的意义： 英汉两种语言在时态表达方式上有很大的差异： 如，“他经常帮助我。”“他昨天帮助我了。”和“他一直在帮助我。”这三句话当中，汉语的动词“帮助”没有任何变化，而是用“经常”、“一直”和“昨天”分别表达出时间的区别。 英语就不同，它必须用动词本身的形态变化来完成任务。 He often helps me. 他经常帮助我。 He helped me yesterday. 他昨天帮助我了。 He has been helping me. 他一直在帮助我。 在这几句中，动词help的意义没有变化，但形态变了. 我们初中英语需要掌握多少个时态呢？ 一．初中英语常见的八种时态 1 一般现在时 1）经常性或习惯性的动作，常与表示频度的时间状语连用。 时间状语：often ,usually, always, every day/week…, sometimes, at…, on Sunday。 例如：I leave home for school at 7 every morning. 每天早上我七点离开家。 提醒：当第三人称单数作主语时，别忘了动词的变化 He usually goes to school by bike. 2）客观真理，客观存在，科学事实。例如： The earth moves around the sun. 地球绕太阳转动。 Shanghai lies in the east of China. 上海位于中国东部。 3）表示格言或警句。例如： Pride goes before a fall. 骄者必败。 注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。 例：Columbus proved that the earth is round. 哥伦布证实了地球是圆的。 2 一般过去时 1）在确定的过去时间里所发生的动作或存在的状态。时间状语有：yesterday, yesterday morning/afternoon/evening, last week/month/year, an hour ago, the other day, in 1982等。 例如：Where did you go just now? 刚才你上哪儿去了？ 2）表示在过去一段时间内，经常性或习惯性的动作。 例如：When I was a child, I often played football in the street. 我是个孩子的时候，常在马路上踢足球。 Whenever the Browns went during their visit, they were given a warm welcome.
宾语从句综合分析(时态、语序、引导词,每部分均含讲解、练习和答案)
宾语从句综合分析（时态、语序、引导词，每部分均含讲解、练习及答案）目录：（一）宾语从句基础讲解 （二）宾语从句的转化 （三）典例讲解 因此，简单地来说，整个句子担当宾语成分，那么这样的句子就叫宾语从句。 （一）宾语从句基础讲解 1. 概念: 在句中担当宾语的从句叫宾语从句，宾语从句可作谓语动词的宾语，也可做介词的宾语。 E.g. He said he was good at drawing. (动词宾语) He asks him how long Mike has been down . (动词宾语)
Miss Zhang is angry at what you said. (介词宾语) 2. 连接词 (1) 陈述句转化成宾语从句时，引导词用that,口语中常常省略。 e.g, She told me (that) she would like to go with us. (2) 以 whether 或if 引导的宾语从句, 主要用来引导一般疑问句意思或选择疑问句意思的宾语从句，从句同样是陈述语序 E.g. I wonder if /whether u have told the new to Li Lei . (3) 特殊疑问句转化成宾语从句时，引导词用特殊疑问词；引导词后要用陈述句语序。 E.g. Could you tell me what's the matter/wrong with you? 特殊情况：当do you think后接特殊疑问句转化成宾语从句时，句式结构应为引导词＋do you think＋陈述句语序。
3. 宾语从句时态 a. 当主句是一般现在时，一般将来时或祈使句时，从句不受主句的限制，根据自身的需要选用相应的时态。例如： Do you know（if/whether he has seen the film）? b. 当主句是一般过去时，从句要用过去时的相应时态。例如： I didn't know （if/whether he had seen the film.） 注意：当主句是一般过去时，而从句表示的是客观真理，自然现象，科学原理，格言等，从句仍然要用一般现在时。 例如： He said （that the earth moves round the sun.） The teacher told us （that light travels much faster than sound.） 4. 人称的变化和标点的使用 a. 从句的主语如果是第一人称，变为宾语从句则与主句的主语一致；如果是第二人称，则与主句的宾语一致；如果是第三人称，不用变化。 (一主二宾三不变) “May I use your knife？”He asked me. →He asked me if he might use my knife. “Do you know her telephone number?” He asked me. →He asked me if I know her telephone number. b. 宾语从句的标点均由主句决定。 主句是陈述句，用句号；主句是疑问句，用问号。如： Who will give us a talk? I don’t know. → I don’t know who will give us a talk.
