高一被动语态教学案
高一被动语态学习
导入:回顾旧知识
The classroom is cleaned by students everyday.
My bike was stolen last night.
一.语态:语态时动词的一种形式,用来说明主语跟谓语动词的关系,英语分为两种语态。 主动语态: 主动语态表示主语是动作的 _____。We planted the tree.
被动语态:被动语态表示主语是动作的 _______。The tree was planted by us.
一般说来,只有需要动作对象的及物动词才有被动语态。
二.被动语态构成:be +及物动词的过去分词(be+done)
三.被动动态的使用:
(1)不知道 或没必要说出 动作的执行者时,用被动语态。
The old bridge was built many years ago.这座古桥是很多年前建造的。
He was elected chairman. 他被选为主席。
(2)强调动作的承受者,此时动作的执行者由“by+动作的执行者”跟在be +done 后面,也可省略。
This good was asked by the monitor.
四.主动变被动的方法:
1.被动句的主语:将主动句的宾语变成被动句的主语
2.被动句的谓语:将主动句的谓语动词改为“be+done”
3.被动句的宾语:将主动句的主语前加by 放在谓语动词之后。
如:they held a meeting yesterday. A meeting was held (by them)yesterday.
主动语态变被动语态的注意事项:
1)在“主语+谓语(pass,lend,buy,write,bring, show,tell...)+间接宾语+直接宾语”句型中,最好把间接宾语变成被动句的主语;
若把直接宾语变成被动句的主语,则需在间宾前加to/for.
E.g. She gave me a book.(直宾:_____;间宾:______;)
I was given a book by her.
A book was given to me by her.
①.His mother told him a story.
He ____ ____ a story by his mother . 或 A story ___ ___ ____him by his mother.
②.He often lends me a pen.
I ___ often ____a pen by him. 或 A pen __ often ____ ____ me by him.
2). 动词短语的被动:不能分割,必须将其看作一个整体,不可漏掉介词或副词。
如:They The baby
五:必修2中三种时态的被动语态
初中已学习过一般现在时、一般过去时、情态动词的被动语态,今天我们将接着学习一般见来时,现在完成时和现在进行时的被动语态
(一) 必修2-Unit2 一般将来时被动态 (意为:将要被。。。)
1.用法:发生在将来的事
2.标志词:tomorrow, next day/month/year等表将来时间的词
3.结构:
例子: A new school will be built next year.明年,一所学校将要被建。
假设下面是你们学校的一则体育海报,你能看懂海报的内容吗?
(二) 必修2-Unit 3 现在完成时被动态(意为:已经被。。。)
用法:动作从过去持续到现在,或已经结束但对现在有影响
标志词:since, already, yet, for+一段时间, so far, by now.(注意: 句子里出现具体的
过去时间,就不能用完成时!)
结构:has/have done→has/have been done (过去时:had been done)
例子:This problem has been discussed(讨论) for two weeks.
请翻到必修2 P21,2,3

Look at the way your hair has been combed
Look at your shoes have been cleaned
You bad better do them again
Look at the way your flowers have been planted

Look at the way the paths have been swept
(三)Unit 4 现在进行时被动态(意为:正在被。。。)
用法:现在正在进行的事
标志词:now
结构:am/is/are doing→am/is/are+being done
(过去时:was/were being done)
例子:A new school is being built now.

高频考点:
考点1.动词的主动形式表示被动含义
.1.某些连系动词用主动形式表示被动意义
1) 感官动词: look, sound, smell, taste, feel,touch,taste....
Beyond’s songs sounds very encouraging. Beyond 的歌听起来很励志。 The meal in Leizhou tastes terrible. 雷州的饭菜很糟糕。
2).表示主语内在“品质”或“性能”的某些动词,虽然可以做及物动词,但这时用作不及物动词,如:wear, write , sell, wash, read,clean , cut,shut....
The book sells well.这本书很畅销。
This knife cuts well.这把刀子很好用。
This dress washes easily.这条裙子容易洗。
The cloth wear comfortably.这种布料穿着舒服。
考点2:没有被动语态的动词(这类动词(词组)凡是用在be+done结构中都是错误的)
常见的这类动词:happen发生, take place发生, break out爆发, last持续, belong to属于
①These islands belong to China.
②Great changes have taken place in china.
③ The war broke out in 1937.
