教学过程

Step 1　Warming up

Ask the students to observe the sentences in Language practice.

Step 2　Presentation

1. Ask the students to read the sentences in Language practice.

This week’s match is already more exciting.

It is more difficult to practise in winter.

We are training harder than usual.

This year we want to do better.

2. Help them sum up the grammar.

Grammar

1.形容词比较级的构成：

规则变化：

不规则变化：

2.副词的基本用法

英语中的副词该如何使用呢？应该放在句中的什么地方呢？一般说来，副词主要用来修饰动词、形容词和副词。

She plays the piano badly.她钢琴弹得很糟。

I’m really tired after last night’s tennis match.昨晚的网球赛后我真的很累。

注意副词与形容词在位置及功能上的不同，试比较：

The teacher speaks carefully. 这位老师讲得很仔细。

The teacher is careful. 这位老师很细心。

副词   修饰动词时通常出现在行为动词（实义动词）之后。

形容词  通常位于系动词之后或名词之前。

形容词变副词的方法

a. 直接 + ly，如：

careful + ly  → carefully   

quick + ly → quickly  

safe + ly → safely

b. 以辅音字母+y结尾，变y为i，再+ly，如：

busy + ly → busily  

heavy + ly → heavily

3.副词的比较级

副词比较级和形容词比较级的变化形式大致相同，也分规则变化和不规则变化两种。

(1)We are training 　harder　 because we want to win.

我们训练得更刻苦，因为我们想要获胜。

(2)This year we are training 　more carefully.

今年我们训练得更认真了。

(3)Sam did 　better　 this year than last year.

萨姆今年做得比去年好。

拓展：“the +比较级，the +比较级”是比较级表达中的一个固定句式，表示“越……，越……”。

The faster you run，the earlier you will be there.

你跑得越快，就越早到达那里。
