语法专题 一般现在时的被动语态
1.被动语态概述
语态是动词的一种形式,用以说明主语与谓语动词之间的关系。英语中的语态有两种: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。被动语态是动词的一种特殊形式,一般说来,只有及物动词才有被动语态。汉语往往用“被”“受”“给”等词来表示被动意义。
例:He opens the door.他打开这扇门。(主动语态)
The door is opened.这扇门被打开。(被动语态)
2.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。被动语态的时态变化只改变be的形式,过去分词部分不变。疑问式和否定式的变化也是如此。
(1)被动语态的句式变化:
以一般现在时和动词invite为例,列表说明被动语态的句式变化:
(2)表示客观的说明常用“It is+过去分词+that…”句型。
例:It is believed that he is a spy.=He is believed to be a spy.大家认为他是个间谋。
知识拓展
其他常见的“It is+过去分词+that...”句型还有:
It is reported that...据报道......
It is said that...据说......
It is suggested that...有人建议......
3.主动语态变为被动语态的步骤
(1)将主动句的宾语变为主语。
Tom saves him.汤姆救了他。
→ He is saved by Tom.他被汤姆救了。
小贴士
如果主动句的宾语是代词,需将其由宾格变为主格。
(2)将动词改为be+过去分词”。
They hold a meeting today.今天他们召开了一次会议。
A meeting is held by them today.今天会议是由他们召开的。
小贴士
be动词与新主语在数上保持一致,时态不变。
(3)将主动语态的主语改为by…放在谓语动词后。
He sings the song.他唱这首歌。
→ The song is sung by him.这首歌是他唱的。
They don't forgive me.他们没有原谅我。
→ I am not forgiven by them.我没有被他们原谅。
小贴士
如果原主语是代词,则应由主格变为宾格。
4.主动语态变为被动语态的注意事项
(1)主动句中的主语如果是people, we, you, they, somebody等含糊地表示“人们”“大家”的单词,变为被动句时,通常去“by…”,但原主语被强调时除外。
We believe she is a good teacher.我们认为她是一位好老师。
→It is believed that she is a good teacher.她被认为是一位好老师。
(2)含有双宾语(直接宾语和间接宾语)的句子,每个宾语都可变为被动语态的主语,即其被动语态有两种形式,但多以间接宾语作主语。
Jack tells us the truth.杰克告诉了我们真相。
→We are told the truth by Jack./The truth is told to us by Jack.
真相是杰克告诉我们的。
5.动词的主动形式表示被动意义
以主动形式表示被动意义的动词多为连系动词,如:look, feel, smell等,下列动词(短语)没有被动式:happen, cost, take place, have。
昨天发生了一起事故。
An accident was happened yesterday. (X)
An accident happened yesterday. (√ )
The flower smells sweet.这花闻起来很香。
The watch looks very good.这块手表看起来很好。
This book sells well.这本书很畅销。
6.一般现在时的被动语态的句式变化
(1)肯定句:主语+am/is/are+及物动词的过去分词+其他.
The kite is made by Mary.这个风等是玛丽做的。
(2)一般疑问句及其答语:Am/Is/Are+主语+及物动词的过去分词+其他?
肯定回答:Yes,主语+am/is/are.
否定回答:No,主语+isn't/aren't.或No, I'm not.
-Is the kite made by Mary 这个风筝是玛丽做的吗?
-Yes, it is.对,它是。/No, it isn't.不,它不是。
(3)否定句:主语+am/is/are +not+及物动词的过去分词+其他.
The kite isn't made by Mary.这个风筝不是玛丽做的。
方法技巧 一般现在时的被动语态
一般现在时,被动用 be done, be有am, is, are。否定be后加not,疑问be放主语前。
链接中考
(重庆中考)-How clean your car is!
-Thank you. It very often.
A.is washed B. washes C. was washed D. washed
解析:分析句子结构可知,主语it是谓语动词wash动作的承受者,要用被动语态。由句中的often可知用一般现在时态,一般现在时的被动语态结构为:am/is/are+及物动词的过去分词。句子主语it是第三人称单数,be动词应用is,故选A。

语法专练参考答案与解析
1.BA项构成一般现在时的主动语态;B项构成一般现在时的被动语态;C项构成现在进行时的主动语态;D项构成在一般过去时的被动语态。由此句的主语 an early arrival(早到达)与谓语动词 advise(建议)之间是被动关系可知,此处应用被动语态;再由前一分句意思“我们打算明天坐高铁去西安”可知,是现在在谈论某事,因此后一分句“建议早到车站”也应该用现在时态。故用一般现在时的被动语态,选B。
2.B分析句子结构可知,主语rice是谓语动词grow的承受者,要用被动语态。由句意“在许多国家,例如中国和印度,水稻靠人工种植”可知,要用一般现在时态,一般现在时的被动语态的结构:am/is/are+过去分词。故选B。
3.B结合选项可知句意为“在美国,你不应该参加家庭聚会,除非你被邀请”。故此处应用肯定形式,排除A;由主句为一般现在时可知,从句应用一般现在时的被动语态,其构成:am/is/are+及物动词的过去分词,故选B。
4.A本句novel主语(小说)和谓语动词read(读)之间存在被动关系,即主语是谓语动词表示的动作的承受者,此时句子应使用被动语态,谓语动词的构成为“be+及物动词的过去分词”,首先排除C项。再由时间状语 today 可知,本句是一般现在时,而D项用了一般过去时的被动语态,也应排除。本句主语novel是单数形式,所以be动词用is,再排除B项。故选A。
5.B结合选项可知句意为“当人们吃中餐时,筷子每天都被用到”。该句应使用一般现在时的被动语态,其构成为:am/is/are+及物动词的过去分词。主语 chopsticks为复数形式,应用are,故选B。
