the Comparative Degrees Revision说课稿

the Comparative Degrees Revision说课稿
Good morning, teachers. My topic is “the Comparative Degrees Revision”
The teaching designs include four parts:
 Analyze the Teaching Materials
 Revision Aims
 Teaching and Learning Methods
 Teaching Procedures
Part I .Analyze the Teaching Materials
1. Analyze the books and students.
This class is about comparative degrees. It not only arouses the students’ interest, but also it’s close to the students’ lives. It is easy to be accepted by the students. This lesson can help them to improve their ability of expressions. At present, the students have the ability of reading, speaking, talking and writing, but we can improve their oral expressions by reviewing the comparative degrees.
Part II. Revision Aims
1. Knowledge Aims
① Review how to use comparative degrees of adjectives .
②Can compare men and men, things and things with comparative degrees.
2. Ability Aim
Can describe your change with comparative degrees.
3. Emotion Aims
We can talk with each other with comparative degrees.
4. Important and difficult points:
① Review how to compare people.
② Review how to use the comparative degrees of adjectives.
③ The changes of the comparative degrees of adjectives.
Part III: Teaching and learning methods
Teaching methods: “Co-operative method” and read by themselves.
Learning methods:
1. Teach Ss how to review by themselves.
2. Teach Ss how to review in groups
Part IV. Revision Procedures
Step One: Leading-in
We haven’t seen for five months. So I am very glad to see you again. In the last five months, you have changed a lot. The boys become more handsome than before. The girls get more beautiful, too. All of you look more confident than before. So I also changed a lot. For example: I’m heavier than last year. Can you guess why? It’s colder last year than before, so I need more fat and I do less exercise. That’s the reason why I get heavier.
This step is to make the students feel the comparative degrees. According to the differences between five months ago and now, I can increase the interest of this grammar.
Step Two: Brainstorm: compare the following pictures，and make sentences. (the faster, the better.) They are all about the comparative degrees of adjectives. The students can make sentences by themselves according to the pictures. They are from easy to difficult.
This step is to remind the students of the comparative degrees. So they can understand and use it better. It’s easy to review this grammar.
Step Three: Summary
Have a summary about the changes of the comparative degrees.
1.单音节和少数双音节形容词比较级的构成。
1）一般在词尾加-er . tall — taller
2)以不发音的字母e 结尾的，加-r.
nice — nicer large — larger
3)以一个元音字母加一个辅音字母结尾的重读闭音节，先双写辅音字母，再加-er.
thin—thinner fat—fatter big—bigger
4）以辅音字母+y结尾的双音节词，变y为i，再加er.
happy—happier early-earlier healthy—healthier
5)多音节词和部分双音节词要在前面加more .
important—more important serious—more serious
interesting—more interesting
不规则变化:
good/well—better bad/badly—worse
many/much—more little—less
far— farther/further old —older/elder
This step is to make the students review the changes of comparative degrees.
Step Four: Review how to use the comparative degrees:
Show some pictures about comparative degrees and help them study how to use the comparative degrees.
一: 比较级的基本用法：(面向及格边缘生)
1. 表达“A和B一样”，用as …. as 的结构。
You are as tall as him.
2. 表达“A不如B”,用not as (so)…as 的结构。
I am not as/so outgoing as Tom. 或者：
I am less outgoing than Tom. (less +原级+than)
3、表达“A大于B”，用“比较级+than”的结构。
I am taller than Tom.
Practice: Compare you with your partner. Try to use the following sentences:
I’m as talented as Celina. I’m not as/ so serious as Lily.
I’m shorter than Mary. I’m more outgoing than Bob.
二: 比较级的更多用法：(面向优秀提高生)
1、在形容词比较级前还可用much, still, far, a little，even, a lot来修饰, 表示“…的多”, “甚至…”, “更…”, “…一些”。

2. 表达“越来越…” ，用“比较级＋and＋比较级” ，
多音节词用“more and more＋形容词原级”形式。

• ③She is taller than any other student in our class.

The students in our class are more than those in their class
7、表示倍数的比较级用法：
