主 题：对Unit 9的语法点——形容词、副词比较等级的讲解 学习时间：2014年6月23日－6月29日

内 容：

1. 形容词、副词的级（本课难点） 形容词、副词的级的构成 1) -er和-est型

单音节形容词和部分双音节词在词尾加-er和-est构成比较级和最高级。例如：

原级 比较级 最高级 bright brighter brightest narrow narrower narrowest thin thinner thinnest（双写n） simple simpler simplest（直接加r或st） pretty prettier prettiest（先变y为i）

2) more和most型

多音节词在原级前加more和most构成比较级和最高级。例如：

原级 比较级 最高级 beautiful more beautiful most beautiful important more important most important

3) 变化不规则的比较级和最高级 原级 比较级 最高级 little less 比较少的 least lesser 次要的 old older oldest elder eldest far farther farthest further furthest bad/badly worse worst ill(evil) worse worst good/well better best many/much more most

2. 形容词和副词的应用 1) 同等程度比较：

as + 原级 + as

e.g. Tom is as bright as Mark. 汤姆和马克一样聪明。

This handbag is more beautiful than that one. 这个手提包比那个漂亮。

not as/so + 原级 + as

e.g. Tom is not as/so bright as Mark. 汤姆不如马克聪明。

用表示倍数的词或其他程度副词做修饰语时，放在as的前面。

e.g. This room is twice as big as that one. 这间屋子是那间的两倍大。 Your room is the same size as mine. 你的屋子和我的一样大。

no more than和not more than

no more than 意为“不过是，仅，只”

e.g. We have no more than 20 computers. 我们仅有二十台电脑。 A flag is no more than a sign. 旗帜不过是一种标志。

not more than 意为“至多，不超过”

e.g. We have not more than 20 computers. 我们最多有二十台电脑。

3) 最高级用法：

the +最高级+比较范围

e.g. The Sahara Desert is the biggest desert in the world. 撒哈拉沙漠是世界上最大的沙漠。

Shanghai is one of the world’s largest cities. 上海是世界上最大的城市之一。

She is the most beautiful among the five girls. 她是这五个女孩中最漂亮的。

4) 对比与比较：

the +比较级, the +比较级 越……就越……

e.g. The older I get, the happier I am. 我越变老，越觉得幸福。

The more he read the novel, the more excited he became. 这本小说他越读越兴奋。

比较级+ and +比较级

e.g. Jane became more and more beautiful. 珍妮越来越漂亮了。

5) 可修饰比较级的词

a bit, a little, much, far, a lot, any等

e.g. The experiment was much easier than we had expected. 实验比我们预想的简单多了。

The rent is much / far / a lot more expensive. 租金贵多了。

A. four times as big as B. four times as bigger as C. as four times big D. as big as four times

解析：A。在as ... as句型中，如有表示程度的状语（如 twice, three times），则置第一个as之前，表示前者是后者的几倍。

2. Today’s weather is ______ worse than yesterday’s. A. very B. much C. very much D. much too

解析：B。very用来修饰形容词的原级形式；much修饰比较级；very much一般用来修饰动词； much too常用来修饰形容词的原级形式。

3. — Did the medicine make you feel better? — No. The more _______, _______ I feel. A. medicine I take; and the worse B. medicine I take; the worse C. I take medicine; the worse D. I take medicine; worse

4. — What will you buy for your boyfriend’s birthday? — I want to buy a _______ wallet for him. A. black leather small B. small black leather C. small leather black D. black small leather

解析：B。根据多个形容词作定语次序排列规律，应该是small（大小）+black（颜色）+leather（质地）。
