形容词、副词的原级和比较级
形容词、副词的原级的用法
1、“A+系动词+as+形容词原级+as+B.”，意为“A和B一样……”。如：
Mary is as smart as Mike. 玛丽和迈克一样聪明。
2、“A+行为动词+as+副词原级+as+B.”，意为“A和B做某事一样……”。如：
She does homework as carefully as Mike. 她做作业和迈克一样细心。
形容词和副词比较级的构成
1、单音节和部分双音节词后加-er。具体构成规则为：
(1)直接在词尾加-er，如：long—longer。
(2)以辅音字母加y结尾的双音节词，把y改为i加-er，如：lazy—lazier。
(3)以e结尾的词，直接在词尾加-r，如：nice—nicer。
(4)重读闭音节词词尾只有一个辅音字母时，先双写该辅音字母再加-er，如：big—bigger。
2、部分双音节和多音节词要在词前加more，构成比较级。如：clearly—more clearly;important—more important。
3、不规则变化：good / well→better, bad / badly→worse, many / much→more, little→less, far→farther(距离更远)/ further(距离更远；程度更深)
形容词和副词比较级的用法
1、两者之间进行比较，用than。如：
Jim is smarter than me, but I am more hard-working than him. 吉姆比我聪明，但是我比他勤奋。
2、比较的对象要一致。如：
My schoolbag is bigger than yours. 我的书包比你的书包大。(物跟物比)
I run faster than Jack. 我跑得比杰克快。(人跟人比)
3、形容词、副词的比较级可以用程度副词修饰。修饰比较级的程度副词有: a little (一点)，a lot / much / far (……得多)，even (甚至)等。如：
Yao Ming is much taller than me. 姚明比我高得多。
Jack arrived at school even later than me this morning. 今天早上杰克甚至比我更晚到学校。
4、比较级的句式。
①“The+比较级(+主语+谓语), the+比较级(+主语+谓语).”，意为“越……, 越……”。如：
The harder you work, the better grades you will get. 你越努力学习，你的成绩就会越好。
②“比较级+and+比较级 / more and more+原级(多音节词和部分双音节词)”，意为“越来越……”。如：
Winter is coming. It's getting colder and colder. 冬天来了， 天气变得越来越冷。
Learning becomes more and more difficult as we get older. 随着年龄增长，学习变得越来越难。

(4)重读闭音节词词尾只有一个辅音字母时，先双写该辅音字母再加-er，如：big—bigger。
2、部分双音节和多音节词要在词前加more，构成比较级。如：clearly—more clearly;important—more important。
3、不规则变化：good / well→better, bad / badly→worse, many / much→more, little→less, far→farther(距离更远)/ further(距离更远；程度更深)
形容词和副词比较级的用法
1、两者之间进行比较，用than。如：
Jim is smarter than me, but I am more hard-working than him. 吉姆比我聪明，但是我比他勤奋。
2、比较的对象要一致。如：
My schoolbag is bigger than yours. 我的书包比你的书包大。(物跟物比)
I run faster than Jack. 我跑得比杰克快。(人跟人比)
3、形容词、副词的比较级可以用程度副词修饰。修饰比较级的程度副词有: a little (一点)，a lot / much / far (……得多)，even (甚至)等。如：
Yao Ming is much taller than me. 姚明比我高得多。
Jack arrived at school even later than me this morning. 今天早上杰克甚至比我更晚到学校。
4、比较级的句式。
①“The+比较级(+主语+谓语), the+比较级(+主语+谓语).”，意为“越……, 越……”。如：
The harder you work, the better grades you will get. 你越努力学习，你的成绩就会越好。
②“比较级+and+比较级 / more and more+原级(多音节词和部分双音节词)”，意为“越来越……”。如：
Winter is coming. It's getting colder and colder. 冬天来了， 天气变得越来越冷。
Learning becomes more and more difficult as we get older. 随着年龄增长，学习变得越来越难。

五、短文填空
Every school has rules. They have to be followed by students. However, some people think there are 1 (many) rules than before. Sometimes, students feel unhappy. But the life of the students in ancient times was much 2 (hard).
In the old days, teachers had rights to punish (惩罚) students when they didn’t do what teachers told them to do. But now, teachers have 3 (few) rights.
In fact, following school rules can be 4 (much) important than other things. For example, falling down may happen if students are running in the hallways. Following the rules can also help students to learn 5 (well) than they don’t. When they grow up and go out by themselves, they soon find that following rules is needed.
