英语16大时态8种被动语态.docVIP

动词的时态 在英语中,由于谓语动作发生的时间不同,或表达不同时间存在的状态,谓语动词都要发生相应的变化.这些动词的形式就叫做动词的时态. 英语动词的时态共有16种,列表如下:(以动词write为例) 一般 进行 完成 完成进行 现在 write writes am is writing are has written have has been writing have 过去 wrote was writing were had written had been writing 将来 shall write will shall be writing will shall have written will shall have been writing will 过去将来 should write would should be writing would should have written would should have been writing would 被动语态的构成 一般 进行 完成 现在 am is taught are am is being taught are has been taught have 过去 was taught were was being taught were had been taught 将来 shall be taught will 过去将来 should be taught would 被动语态由助动词be加过去分词构成,时态通过be表现出来.构成被动语态的一般疑问句时,须将第一个助动词移至主语之前,构成被动语态的否定句时,助动词后须加not. 各个时态的被动形式列表如下:(以动词teach为例) 英语被动语态讲解 语态的基本概念和种类语态是动词的一种形式，用来表明主语与谓语动词之间的关系。所以英语的语态是通过动词形式的变化表现出来的。语态有两种：主动语态和被动语态。主语是动作的发出者为主动语态；主语是动作的接受者为被动语态。如：They built the bridge.? ?The bridge was built by them.(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。歌诀是：被动语态be字变，过去分词跟后面。情态动词的被动语态是常考的一个知识点：情态动词+be+过去分词(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 book was published in 1981.? ???这本书出版于1981年。 (2)强调动作的承受者，而不强调动作的执行者。 例如：the window was broken by Mike.? ? 窗户是迈克打破的。 This book was written by him.? ???这本书是他写的。 Eight hours per day for sleep must be guaranteed.? ??每天8小时睡眠必须得到保证。歌诀：谁做的动作不知道，说出谁做的没有必要； 动作承受者需强调，被动语态运用到（四）主动语态变被动语态的方法与注意事项 歌诀是：宾变主，主变宾，by短语后面跟。 谓语动词变被动，be后“过分”来使用。(1) 通常的办法是：将主动结构中的宾语变为被动结构中的主语，将主动结构中的谓语动词变为“be / get +过去分词”形式，将主动结构中的主语变为介词by的宾语(若动作的执行者没有必要说明则可以省略该by短语)。如：Li Lei planted the tree last year. → The tree was planted by Li Lei last year. 这棵树是李蕾去年栽的。Workers made the machines in Changsha. → The machines were made in Changsha. 这些机器是长沙造的。(2) 将含有复合宾语的句子变为被动语态时，应将宾语变为被动结构的主语，而宾语的补足语则留在原处成为主语补足语。如：He painted the door gr
