Unit3 English Around the World
Topic1 English is widely spoken
throughout the world
Topic 1 Section A
一、学习目标:
1、学习并掌握一般现在时的被动语态.
2、了解迪士尼乐园的相关知识,扩大学生的知识面.
二、教学过程:
第一步:复习
师生对话。复习句型 Have you ever been to …… 如:
T: Have you ever to Beijing
S1: Yes ,I have.
T: Which places of Beijing have you visited
S1: I have visited the Great Wall ,the Summer Palace and so on .
T: Have you ever been to the USA
S2: No ,I haven’t .
T: Which place of the USA would you like to visit
S2: I would like to visit ……
第二步:呈现
1、T: Do you know Disneyland
Ss: Yes ,We do .
T: What can you see in Disneyland
Ss: We can see Mickey Mouse and Donald Duck .
T: Do you like them
Ss: Yes ,We like them very much .
T: Yes ,They are loved by lots of children .
(把这个句子板书在黑板上后,再举两个例子)
Disneyland is enjoyed by millions of people from all over the world .
Disneyland is visited by millions of people in Hong Kong .
2、让学生观察黑板上的三个句子,鼓励学生发现规律,教师补充讲解。板书一般现在时的被动语态结构:am/is/are+p.p
第三步:巩固
1、学生以小组形式讨论3b,师生一起归纳主动语态和被动语态的呼唤规律。完成3b,并把变化过程板书在黑板上.
主动语态变为被动语态一般分为三步:
1)把主动结构的宾语变为被动结构的主语(宾语若为人称代词,宾格需变为主格)
2)把主动结构的谓语动词变为“be+p.p”形式(注意人称、时态和数的变化)
3)在动词的过去分词之后加介词by,再将主动结构中的主语放在by之后.(如为人称代词,主格需变为宾格)
2、模仿3a的例句连线造句,操练被动语态,教师核对答案并让学生读这些句子,完成3a.
3、检查学生单词课前预习情况,同时纠正发音.
4、听1a录音,回答下列问题,教师核对答案.
1)Where are Wang Junfeng and his parents going to visit
2) Is Wang Junfeng good at English
5、学生自读1a,找出对话中的重点短语和含有被动语态的句子,并让学生板书在黑板上.
6、学生大声朗读这些短语和句子.
第四步:练习
让学生自主学习,完成1b,并核对答案.
第五步:综合探究活动
收集更多《唐老鸭与米老鼠》和迪士尼乐园的信息,尽量用被动语态的句子与大家分享。通过这一活动扩大学生的知识面.
三、语法:一般现在时的被动语态
1、概念:英语语态有主动语态和被动语态两种。主语是动作的执行者,叫做主动语态;主语是动作的承受者,叫做被动语态。
2、被动语态的基本结构是“助动词be+及物动词的过去分词”。助动词be有人称、数和时态的变化。一般现在时的被动语态构成为:主语+am/is/are+及物动词的过去分词。
3、一般现在时被动语态的句式变化:
1)肯定:主语+am/is/are+p.p
eg: Cars are made by them.
2)否定: 主语+am/is/are+not+p.p
eg: Cars are not made by them.
3)一般疑问句:Am/Is/Are+主语+p.p?
eg: Are cars made by them ?
4、被动语态的用法:
1)在没有指明动作的执行者或者不知道动作执行者的情况下
eg: This coat is made of cotton.
2)要强调动作的承受者时
eg: His bike is stolen.
5、没有被动语态的词:
1)不及物动词。如:happen ,take place ,rise ,grow(生长)等.
2)一部分表示状态的及物动词。如:have ,fit ,cost ,weigh 等
3)系动词。如:feel ,turn ,taste ,sound ,smell ,get 等
6、注意事项:
1)主动语态和被动语态互换时,时态不变.
2)如果不需要强调动作或行为的执行者时,by短语可以省去.
3)若后面的词表示地点,并且不是动作的执行者时,就用介词in,而不用by.
四、当堂巩固练习:
(一)、同义句转化:
1、Pollution is a serious problem in big cities throughout the world.
Pollution s a serious problem in big cities the world.
2、I hope I can go to Beijing University one day.
I go to Beijing University .
3、It took me a long time to finish the work, but I’m very pleased with the results.
It took me a long time to finish the work , but I’m very
the results.
(二)主动语态和被动语态
1、Today people use computers in both cities and towns. Today people in both cities and towns.
2、I write a letter to my parents once a month.
A letter to my parents by once a month.
3、The classroom is cleaned by us every day.
