名词变复数的方法学生只接触过直接加s或es的情况,本课又接触到了其它几种,教师带领学生总结出了名词变复数的方法,层次鲜明,相信学生一定会掌握得很好。
重点难点：
重点:掌握书中提到的四种名词变复数的方法
难点:不规则名词变复数的方法
教学过程：
1、第一学时
2、教学活动
Step One: Greeting and revision
T:Hi,class. How many pupils are there in your class?
Ss:Hi,teacher. There are ____ pupils.
T:Nice to meet you. How’s the weather today?
Ss:_______.
T: I feel cool.What’s the temperature? Do you know?
Ss: Yes.It’s a fine day. I like it
Step Two:New Concept
出示两幅类似的图。T:Can you find the differences?(找不同)
同学们用英文陈述不同点。(设计意图:主要是为了让学生们理解differences的含义)
2、屏幕上展示一些单复数单词:pen???? pens
??????????????????????????? eraser??? erasers
??????????????? ????????????marker?? markers
??????????????????????????? desk???? desks
??????????????????????????? book???? books
T: Can you find the differences?学生们总结单数与复数的不同。(设计意图:再次理解differences的含义及用法。为本课的新授教学做铺垫。)
出示句子总结两列词的不同点:These words have no s. These words have an s.
出示书中第一部分的铅笔图及句子:This is one pencil. These are many pencils.学生们读一读,找到pencil及pencils的不同点。再出示椅子图,让学生说出单复数的句子:This is a chair. These are many chairs.然后学生们写下来。(设计意图:不仅照例子会说句子,还能写句子,练习说和写的能力。)
教师手指pencil,chair,师生共同总结:These words have no s.指pencils,chairs总结:These words have an s.
学生们说一说类似这样变复数的名词。
出示书中第二部分的盒子和公共汽车的图及句子,学生试读:This is a box.These are many boxes. This is a bus. These are three buses. 教师手指box,bus,再手指boxes,buses,示意学生们找不同,并总结出来:These words have no es. These words have an es.
出示其它一些变复数加es的单词,拓宽学生的知识面,如:class,dress,fox,ox,watch,witch,dish,fish,学生们通过读,小组讨论,得出如下结论:以s,x,ch,sh结尾的名词变复数,要在末尾加es.(设计意图:教学要循序渐进,最主要是要学生掌握变复数的规则。)
做一个填空的练习。内容如下:
We have many box____.
I am washing the dish____.
I like those dress____.
There are many bus____ in the city.
The school has many class____.
出示一个西红柿的图,T:What’s this? Ss:It’s a tomato.
出示多个西红柿的图,T:What are these? They are tomatoes.
出示土豆,学生说出句子:This is a potato. These are potatoes.
看照片的句子:This is a photo. These are photos.
T:Do you see an s or an es in these words?手指tomatoes,potatoes and photos,Can you find the differences?
学生们发现tomato,potato要加es变复数,而photo却加s变复数,告之学生要特殊记忆。
出示其它以o为结尾的单词,拓宽知识面。学生们说一说,读一读。
出示第4部分的课文,小组内试着读一读。回答如下问题:What is the woman doing?What are the women doing? What is the child doing? What are the children doing? Can you find the differences?同学们回答问题,得出结论:man—men, woman—women, child—children
教师手指这些单词,告诉学生们:They are irregular plurals.Please remember them specially.
T:I’ll show you some others.出示more irregular plurals.(foot——feet????????? people——people
tooth——teeth??????????? deer——deer
wife——wives??????? family——families
mouse——mice????????? baby——babies)师生共同读一读。
T:你学会了几种名词变复数的方法呢?小组内讨论,之后小组内出代表阐述一下,其他同学可以补充。教师与同学们共同总结这些方法。
检验学生们名词变复数的方法掌握得如何?出示一些杂乱无章毫无联系的单词,由每组组员先讨论如何变复数,之后告之全班同学,你通过讨论,知道了什么?
最后欣赏歌曲“The Rain Song”,如果会唱可以和音乐一起唱,如果不会,可以欣赏。在音乐声中结束这堂课。
Step Three:Homework
总结所有名词变复数的方法,在每一类下写出自己所掌握的符合这类变复数方法的单词。
