一、 需要使用被动语态的情况
学习被动语态时,不仅要知道被动语态的语法结构,还要知道在哪些情况下需要使用被动语态.
1. 说话者不知道动作的执行者或不必说出动作的执行者（这时可省略by短语）.
例如：His computer was stolen last week. 他的电脑上星期被偷了.
2. 借助被动的动作突出动作的承受者.
例如：Peter was given half an hour to decide whether he would accept the offer. 皮特被给了一个小时的时间决定是否接受这个提议.
3. 为了更好地安排句子.
例如：The singer got on the bus and was immediately recognized by people. 这位歌星上了公交车,立刻就被人们认了出来.（一个主语就够了）
4. 用于It is said that从句及其他类似句型.
例如：It is said that the girl has passed the exam. 等于 The girl is said to have passed the exam. 据说那个女孩通过了那场考试.
二、 被动语态的构成
被动语态由“be+动词的过去分词”构成,be动词随时态的变化而变化.以do为例,各种时态的被动语态如下：
一般现在时am/is/are+done
现在完成时has/have been done
现在进行时am/is/are being done
一般过去时was/were done
过去完成时had been done
过去进行时was/were being done
一般将来时shall/will be done
过去将来时should/would be done
在主动语态中,“情态动词+动词原形”作谓语,其被动形式为：情态动词+be+动词的过去分词.
三、主动语态变被动语态的一般规律
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+动词的过去分词”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）.
例如：My father planted the tree last year.→The tree was planted by my father last year.
Workers made the cars in Shanghai. →The cars were made in Shanghai.
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,而宾语补足语则留在原处成为主语补足语.
例如：The old man painted the bed white yesterday. →The bed was painted white yesterday.
表示“使,让”的动词make, have等,以及感官动词see, feel, hear等,在主动语态中,接动词不定式作宾语补足语时,动词不定式前的to要省略,而变为被动语态时,成为主语补足语的动词不定式必须带to.
例如：I hear her sing in the classroom. →She was heard to sing in the classroom.
3. 带双宾语的句子变为被动语态时,既可将直接宾语变为被动语态的主语,而在间接宾语前加to或for将其留在动词之后；也可将间接宾语变为被动结构的主语,而直接宾语留在动词之后.
例如：My mother gave me the schoolbag last week. →The schoolbag was given to me last week./I was given the schoolbag last week.
一般来说,间接宾语前带to的动词有bring, give, lend, pass, post, send, show, take, tell, write 等；间接宾语前带for 的动词有book, buy, call, cook, do, get, make, save等.
4. 动词say, believe, consider, expect, know, report, suppose, think等的被动语态常有两种结构形式.
例如：Henry was said to get hurt in the car accident. 等于 It was said that Henry got hurt in the car accident.
5. 短语动词变被动语态时,短语动词后面的介词或副词不能省略.
例如：The student’s plan was laughed at by others. 这个学生的计划被其他人笑话了.
四、 主动语态表被动含义的几种情况
1. 英语中有很多动词,如sell, write, read, open, lock, shut, wear, wash, cut, burn 等,当它们被用作不及物动词来描述主语特征时,常用其主动形式表示被动含义,主语通常是物.
例如：This kind of cloth washes well. 这种布很好洗.
【注意】主动语态表示被动含义强调的是主语的特征,而被动语态则强调外界作用造成的影响.
试比较：The door won’t lock.（指门本身有毛病）
