英语中的语态系统很多，知识很多。掌握语态的使用对学习英语具有重要意义。
今天，小编为学生们带来了相当丰富的与被动语态使用相关的语法。
不清楚的赶紧做好笔记！主动和被动语态转换的原理主动语态和被动语态概述英语语态分为主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。被动语态由助动词组成be 过去分词构成：Everybody likes him. 每个人都喜欢他。
He is liked by everybody. 大家都喜欢他。
主动语态变被动语态的方法1. 主动语态变被动语态的基本方法将主动语态的宾语变成被动语态的主语，把主动谓语变成被动谓语，把主动语态的主语变成主动语态by短语:He broke the cup. → The cup was broken by him.注如果不强调动词执行者，则在被动语态中by短语通常可以省略：He was born in 1986. 他生于1986年。What is this flower called 这种花叫什么花？2. 双宾动词的被动语态双宾动词是指带有双宾语的动词。当它们变成被动语态时，它们通常将间接宾语变成被动语态的主语，并保留直接宾语：He answered me that question. → I was answered that question by him.有些动词通常把直接宾语变成被动语态的主语，把间接宾语变成介词to 或for引起的状语:He wrote her a letter. → A letter was written to her. She made him a new coat. → A new coat was made for him. 有时可以使用以上两种方法：He gave her some money. 他给了她一些钱。
→ She was given some money. / Some money was given to him.He bought her a watch. 他给她买了一块表。→ A watch was bought for her. / She was bought a watch.3. 被动语态时态被动语态时态由被动结构be 过去分词中的动词be其基本结构和用法如下：★ 一般现在的被动语态:am [is, are] 过去分词English is taught in our school. 我们学校学英语。

★4. 包含情态动词的被动形式如果谓语在主动语态中含有情态动词，则情态动词通常应保留在相应的被动语态中，其结构为情态动词 be 过去分词：Everyone must know this. →This must be known by everyone.请参见以下情态动词被动句实例：This can’t be done in a short time. 这不能在短时间内完成。Can this be done by machine 机器能做到这一点吗？The work must be done at once. 这项工作必须立即完成。
