形容词比较级的用法讲解与练习演示教学.docx

1、形容词比较级的用法讲解与练习演示教学形容词比较级的用法讲解与练习形容词比较级的用法讲解与练习一、原因分析：1、英语中形容词的比较等级这一用法与汉语语言习惯有着很大不同，因而学生在理解和使用上会存在一些障碍。2、英语形容词比较级有着很多灵活多变的使用方法，学生初次接触这一语法，需要老师进行必要的指导。二、采取措施：1、从形容词原级的用法开始引入比较级的用法。2、使用多媒体等教学手段，给学生创造交际环境。3、采用小组、同桌、师生之间的多种交流、讨论的形式，进行对话练习，学习、理解并正确使用该语法。三、教学设计：（一）、教学目标：1、掌握一些常用形容词的比较级的形式。good-better; bad

2、/ill- worse; fat-fatter; heavy-heavier; boring- more boring2、掌握形容词比较级的构成规则，正确运用形容词的比较级。A good friend likes to the same things as me.The harder you work at your study, the better grades you will have.This book is far more interesting than that one.He has learned as many English words as his brother.O

3、f the two girls, Linda is the taller.Well make our country more and more beautiful. （二）、教学重难点：1形容词比较级的构成方法。2形容词比较级的用法。 （三）、教学步骤： Step 1: Show the teaching aims.(展示教学目标)。Step 2：Revision(上节课我们学习了Unit 6 Section A，已经重点学了形容词比较级的构成方法，让学生通过复习笔记小组交流的方式，复习形容词比较级的构成及基本用法.)一、写出下列形容词的比较级。1. quiet _ 2. interesti

4、ng _ 3. outgoing _4. many _ 5. ill _ 6. wet _7. good _ 8. athletic _ 9. funny _ 10. important _二、Ask and answer in pairs to compare things.Step 3: Lets learn and practice the grammar. (语法讲解与操练。)上节课，我们学习了形容词比较级的基本用法，即用于两个人或事物的比较,其结构形式如下:主语+谓语(系动词)+ 形容词比较级+than+ 对比成分。也就是, 含有形容词比较级的主句+than+从句。注意从句常常省去意

5、义上和主句相同的部分, 而只剩下对比的成分。It is warmer today than it was yesterday.今天的天气比昨天暖和。This picture is more beautiful than that one.这张照片比那张照片漂亮。The sun is much bigger than the moon.太阳比月亮大得多。Today were going to learn some new ways of comparing things.（今天我们来学习进行比较的几种其他用法。）1. 同级比较两个比较对象程度相同时，用“as+形容词原级+as的结构”例如： To

6、m is as tall as his brother. My hair is as long as mine.在这两种结构中，第一个as是副词，而第二个as是连词；在第二个as的后面接名词、句子或代词的主格（一般不要接代词的宾格）。例如： His bedroom is not as big as his sisters. It is not so hot as yesterday.学生两人一组使用as as 及 not as(so) as练习同级比较。 2、在比较级 + than的结构前可以加上某些副词类的词，以对其进行修饰，如：far（远），even（甚至），much（许多），still（

7、更，还），a lot（许多），a little / bit（一点），rather（相当地），等等。例如： Shes a little more outgoing than me. My bike is much newer than his. 3、 比较级中的两个特殊作用的结构是：a. The + 比较级 + 句子，the + 比较级 + 句子 。它表示的意义是越（怎么样就）越（怎么样），在这个结构中的两个比较级不要求一定词性相同，它们各自的词性要依句子的需要而定。例如： The harder you work at your study, the better grades you will

8、 have. 你学习越努力，你的成绩就越好。The more we get together, the happier well be. 朋友越多， 我们就越高兴。Ask and answer in groups to make some new sentences.b. 比较级+ and + 比较级。它表示的意义是越来越（怎么样），在这个结构中的两个 比较级则要求词性相同。例如： Our country becomes more and more beautiful.When spring comes, the weather is warmer and warmer. 4、 比较对象中一方

9、不及另一方时，用“not as(so)+形容词原级+as ”或“less+形容词原级+ than”的结构。 He is not as careful as his sister. = He is less careful than his sister.= His sister is more careful than he.Ask and answer in groups to make some new sentences. 5、 在两者之中选择“较为、 ” 的一个， 比较级之前加the.例如： Amy is the taller of the two girls. Of the two

10、books, the one on the right is the better. 6、比较级的形式表达最高级的意思。在这种情况下，往往是将一个人或是一件事与其他所有的人或事相比较。做这种句子时有一点要特别注意-别忘了常在比较状语中用any other , else类的字眼，以将比较主体排除在比较对象以外，因为自己不可以与自己相比较。例如：He is taller than anyone else in our class.He is taller than the other students in our class.He is taller than any other student

11、 in our class.He is the tallest in our class. 以上四句话意思相同出示习题，老师引导学生在理解的基础上做同义句转换。Step 4： Take notes about these grammar points.Step 5: Practice (课堂练习)：a. Choose:1.
