英语八种动词时态讲解
英语八种动词时态讲解 1、一般现在时 主要用于下面几情况： 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。在这种情景中，句子常带有表示频率的时间状语：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如： They raise ducks as a sideline .他们以养鸭为副业。 She doesn't often write to her family, only once a month. 她不常给家里写信，仅一月一封而已。 I cycle to work every day .我每天骑自行车上班。 It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。 例如: He can speak five foreign languages .他能说五种外语。 That is a beautiful city .那是座美丽的城市。 Changjiang River is one of the longest rivers in the world. 长江是世界上最长的河流之一。 She majors in music .她主修音乐。 All my family love football .我全家人都喜欢足球。 My sister is always ready to help others . 我妹妹总是乐于助人。 3) 陈述客观事实、客观真理。顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。 例如： The sun rises in the east .日出东方。 The earth goes around the sun .地球绕着太阳转。 Ten minus two is eight.十减二等于八。Light travels faster than sound .光的速度比声音的速度快。 The United States lies by the west coast of the Pacific Ocean. 美国位于太平洋西岸。 4) 根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。 例如： I'll tell him the news when he comes back. 他回来时，我将告诉他这个消息。 If you take the job , they will talk with you in greater details. 如果你接受这份工作，他们将和你谈谈细节。 用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now, today , nowadays等等。 2、一般过去时 主要是用来描述在过去某个时候发生的动作或存在的状态。它也可以用来表示在过去某段时间里经常发生的习惯性动作。这一点在表达意义上与一般现在时相同，只是所在的时间区域不同而已。由于它的主要作用如此，所以在使用一般过去时的句子里常常有一个意义较具体的过去时间状语。这也是它与现在完成时的最大区别之一。 一般过去时由谓语动词的过去式表示，也就是说动词词末要加-ed（除不规则动词
常见的八种英语时态详解精编版
常见的八种英语时态详解 时态（Tense）是表示行为、动作和状态在各种时间条件下的动词形式。因此，当我们说时态结构的时候，指的是相应时态下的动词形式。英语时态分为16种 1. 一般现在时 基本结构：①be动词am/is/are；②行为动词原形或单数第三人称。 否定形式：①am ／is ／are ＋________；②此时态的谓语动词若为行为动词，则在其前加_________，如主语为第三人称单数，则用___________，同时还原行为动词。 一般疑问句：①把be动词放于句首；②用助动词do提问，如主语为第三人称单数，用does，同时，还原行为动词。 提示词：always , everyday , often , once a week (month , year , etc.) , sometimes , seldom , usually 1) 描述当前时间内经常出现、反复发生的动作或存在的状态。 She doesn't often write to her family, only once a month. It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。 这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如：

初中英语八种时态详解及练习讲解学习
初中英语语法：动词八种时态、被动语态详解练习及答案： 一、初中英语被动语态用法小结 [1]一、语态概述 英语的语态是通过动词形式的变化表现出来的。英语中有两种语态：主动语态和被动语态。 主动语态表示主语是动作的执行者。 例如：Many people speak Chinese. 谓语：speak的动作是由主语many people来执行的。 被动语态表示主语是动作的承受者，即行为动作的对象。例如：Chinese is spoken by many people. 英语English是动词speak的承受者。 二、被动语态的构成 被动语态由“助动词be＋及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。现以speak为例说明被动语态在各种时态中的构成。 一般现在时：am／is/are＋spoken 一般过去时：was／were＋spoken 一般将来时：will／shall be＋spoken 现在进行时：am／is／are being＋spoken 过去进行时：was/were being＋spoken 现在完成时：have／has been＋spoken 过去完成时：had been + spoken 三、被动语态的用法 （1）不知道或没有必要说明动作的执行者是谁。 例如：Some new computers were stolen last night.一些新电脑在昨晚被盗了。（不知道电脑是谁偷的） This bridge was founded in 1981.这座桥竣工于1981年。 （2）强调动作的承受者，而不强调动作的执行者。 例如：The glass was broken by Mike.玻璃杯是迈克打破的。
