比较级最高级基础教案

形容词-副词的比较

教学重点：adj、adv的比较级

教学难点：比较级的倍数表达法

教学过程：

一、用法：

用于两者（人或物）之间，表示“其中一个比另一个更……”或“较……”，后面通常用连词than连结另一个比较的对象，其基本句型是：

主语＋谓语（系动词）＋形容词比较级＋than＋对比对象。

ex. Jim is than Mike. （tall）

Mike is than Jim. （short）

It’s today than it was yesterday. （hot)

二、形容词、副词比较级和最高级的构成

2.部分形容词的比较等级变化时不规则的：

在原级前面通常使用very, quite, too, much too, so 等。

ex: 1. The room is very big.

2. The person is quite clever.

3. Today is too hot.

4. He eats too much, so he’s much too heavy.

5. I’m a little hungry, I’d like something to eat.

6. Jim is as tall as Tom.

7. Your English is so good.

在比较级前面使用的修饰词有：even（更，更加），a little（有点），far/ much/ a lot （更加，……的多）

ex: 1. Yesterday was hot, but today is even

2. I’m a little than Mary. tall

3. This skirt is far/ much/ a lot than that one. beautiful

三、最高级

（一）、含义：表示三者或三者以上的人或物进行比较时，用最高级。形容词的最高级前面要加定冠词the，副词最高级前面的the可以省略。在含有最高级的句子中，常有一个in/of 短语来表示比较范围。如：in my class, in China, of the students, of all, of the three等。

（二）、最高级的变化规则：同前面我们学的比较级的变化规则基本相同，最高级的变化规则也分为规则变化和不规则变化两种。规则变化就是在词尾加est。

1. clean, small, long, hard

2. heavy, dirty, healthy, happy

3. big, thin, fat, hot

4. late, nice, large

多音节或部分双音节单词构成最高级时，在前面加most：

difficult, interesting, beautiful; slowly, quickly, friendly, easily;

特殊变化：good—better—best; bad/badly/ill—worse—worst

many/much—more—most; little—less—least;

;

（三）最高级的用法

1. 表示三者或三者以上的人或事物比较时用最高级：

①He is (strong) of the three.

②Shanghai is (big) city in China.

③Mike did (badly) in this test.

④Who speaks English (well) in your class?

2. 表示三者或三者以上的人或事物进行选择时，用which/who is +the+形容词的最高级，+A、B、or C？

①is the (interesting) subject, math, art or English?

② is (fat), Jim, Tom or Jack?

③ sings (well), Mary, Kate or Lucy?

3. be + one of the +最高级+复数名词，表示“最……的……之一”。ex:

①West Lake is one of (beautiful) places in China.

②Mike is one of (tall) students in our school.

4. be + the+序数词+最高级+单数名词+范围，表示“……是第几个……的”。ex:

①The Yellow River is the second (long) in China.

②I think English is the most interesting subject. And math is the second (interesting ) one.

5. be + the +最高级+人或物+定语从句（that +主语+have/has +ever+过去分词）

①This is (beautiful) city that I have ever visited.

②It’s (good) news that I have ever heards today.

③It’s(tall) person that I have ever seen.
