1. Students learn the rules of the regular change of the adjectives and adverbs individually, and then several students explain the points to the whole class. At last the teacher corrects their mistakes. 构成法 原级 比较级 最高级 一般单音节词未尾加-er,-est tall taller tallest 以不发音的e结尾的单音词和少数以- lenice nicer nicest 结尾的双音节词只加-r,-st [来源学科网]以一个辅音字母结尾的闭音节单音节词，双写结尾的辅音字母，再加-er,-est \以辅音字母+y\结尾的双音节词，改y为i，再加-er，-est 少数以-er,-ow结尾的双音节词未尾加-er,-est big busy clever/narrow bigger busier biggest busiest cleverer/ cleveresnarrower t/ narrowest 其他双音节词和多音节词，在前面加importanmore most more，most来构成比较级和最高级 t/ easily importanimportat/ more nt/ most easily easily 2. Students work in groups to discuss the irregular rules of the adjectives and adverbs, and the teacher gives them the help in time and show the points as following: 原级 比较级 最高级 good better best well（健康的） bad, badly worse worst ill（有病的） old older/elder oldest/eldest much/many more most little less least far farther/further farthest/furthest Step 3 Practice
Give students several minutes finish the exercises on page64-65, and the teacher checks the answers in the whole class. Step 4 Summary
The students try to summarize the key points with the help of the teacher. Step5. Ask students to review the expressions of adjectives and adverbs:
形容词、副词原级的用法：用于同等事物相比较，表示相等或不等，用原级进行比较时，通常用 as 构成的句型：as…as ，not as…as ， not so…as.
1）…as+ 形容词、副词原级 +as… ，表示 \与 … 一样，例如： The tree is as tall as that building.
2 ）…as+ 形容词 + （ a ） + 名词 + as … He wants to be as great a scientist as Newton. 3 ）表示倍数：倍数 + as + 原级 + as This room is three times as big as that one. 4 ） … not as /so + 原级 + as … ，表示 \与 … 不一样 \ He cannot run as /so fast as you .
Step 2 Presentation
1. Students learn the comparative degree of adjectives and adverbs on the grammar and underline the key points at the same time.
2. The teacher stresses the important points after students’ self-learning.
Points: 1 ）用于两个事物相比较。比较级 +than表示出A比B更…He is clever than his sister.
注意：比较级前可加表示程度的状语，如：a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。
2) the + 形容词比较级 … ，the + 形容词比较级， 表示 \越 … 就越 …\: Actually, the busier he is, the happier he feels.
3 ）比较级 +and+ 比较级，表示 \越来越 …\ e.g. Our city has become more and more beautiful.
4) “the + 比较级+ of + 两个人或物”表示“两者中较……的一个” e.g. He is taller
[来源学科网][来源学科网]of my two brothers.
5) “…times + 比较级 + than…”表示“比……大（多、长、宽、高等）……倍”e.g. You are 5 minutes later than I.
3. Students work in groups to discuss the superlative degree of the adjectives and adverbs, and explain the key points to the whole class one by one. Then the teacher gives them help in time. Key:最高级的用法：1) 三个或三个以上的事物的比较用 \最高级 \结构表示“最”之意。e.g.： One of the greatest killers in the Western world is heart disease. 2 ）形容词的最高级前应加定冠词 the ，但如果最高级之前有物主代词，则不要加 the 。e.g.: Please send us the goods at your earliest convenience.
3 ）如果不和别的事物相比较，也不必在最高级前加 the 。e.g.： I am busiest on Monday.
4 ）有时最高级表示 \非常 \之意，这时可加不定冠词 a/an 。e.g.： This is a most touching story. Step 3 Practice
Students do the exercises on page65-67 on the grammar book individually, and check the answers in groups. Then the teacher corrects the mistakes of each group. Step 4 Summary
