英语作为一门国际语言,掌握好时态和语态是非常重要的。时态是描述动作发生时间的方式,而语态则是描述主语和谓语之间关系的方式。本文将介绍英语中的八种时态以及被动语态的结构。
八种时态的结构
英语中的八种时态分为四个基本时态和四个完成时态。基本时态分别是:
简单现在时
结构:主语 + 动词原形
例句:I eat breakfast every day.
简单过去时
结构:主语 + 动词过去式
例句:I walked to school yesterday.
简单将来时
结构:主语 + will/shall + 动词原形
例句:I will call you later.
现在进行时
结构:主语 + am/is/are + 动词-ing
例句:I am studying for my exam.
完成时态分别是:
现在完成时
结构:主语 + have/has + 过去分词
例句:I have finished my homework.
过去完成时
结构:主语 + had + 过去分词
例句:I had eaten breakfast before I left.
将来完成时
结构:主语 + will/shall + have + 过去分词
例句:I will have graduated from college by then.
现在进行完成时
结构:主语 + have/has + been + 动词-ing
例句:I have been studying for three hours.
被动语态的结构
被动语态是描述动作的接受者而非执行者的语态。在英语中,被动语态的结构为:
简单现在时
结构:主语 + am/is/are + 过去分词
例句:The book is being read by me.
简单过去时
结构:主语 + was/were + 过去分词
例句:The book was read by me yesterday.
简单将来时
结构:主语 + will/shall + be + 过去分词
例句:The book will be read by me tomorrow.
现在进行时
结构:主语 + am/is/are + being + 过去分词
例句:The book is being read by me right now.
被动语态的结构中,过去分词的形式为动词原形加上-ed。但也有不规则动词,如:go变成了gone,eat变成了eaten。
