Step 1 Grammar Focus
Read aloud the sentences in Grammar Focus.
探究一 形容词、副词比较级的用法
1. 找规律：
⑴ I’m more outgoing than her.
⑵ She is very heavy.
⑶ He works as hard as Tina.
小结：比较级表示两者之间的比较，常用于句型：主语＋谓语动词＋形容词/副词比较级＋than＋比较对象; 而原级前常有very/quite/pretty修饰，用于句型：主语＋谓语动词＋形容词/副词原级。
2. 基本句型
主语＋be/谓语动词＋形容词/副词比较级＋than＋比较对象
3. 童鞋们，让我们来一起翻译下面的句子吧！
①山姆比汤姆矮。

②Ann的头发比Tina的长

③ An elephant is much heavier than a pig.

④ Tom is a little shorter than his friend Jim.

4. 你们有没有注意到句子中加黑单词的翻译，much，表示“……得多”，a little表示“一点儿”。它们是用来修饰比较级的。类似的词汇还有even(更加)、far、a lot(……得多)、a bit(一点儿)、still(还、还要)。
探究二 形容词/副词同级比较
1) Tara runs as fast as Tina.
2) Jim isn’t so hard-working as Tom.
3) Are you as friendly as your friend?
“as+形容词/副词的原级+as”表示“与……一样”，其否定形式为“not as/so…as”, 表示前者不如后者，注意“so+形容词/副词的原级+as”只能用在_______中。
Step 2 Practice
3a用所给单词写出问题并回答。
3b回想一下两年前的你, 写下与你现在有什么不同。
3c比较一下你的父母, 谁更聪明、更有趣等，用（√）在表中标出。然后问你的同伴关于她/他父母的问题。
探究三
Who is smarter, your mother or your father? 谁更聪明，你的妈妈还是你的爸爸？
比较级句式：“特殊疑问词（Who/what/which...）+谓语+比较级，A or B?”用于两者之间的比较，表示“两个中哪一个更……？”
e.g. Who runs faster, Tom or Kay? 谁跑得更快，汤姆还是凯？
Which skirt is more beautiful, the big one or the small one?
哪件裙子更漂亮，这件大的还是这件小的？
【课时小结】
