Unit 3 I’m more outgoing than my sister
Period 1 （Section A 1a---1c）教学设计
【教材分析】
本教材采取循环滚动的内容安排体系。本单元出现的语言材料如人物的外貌特征、性格特征在初一下册都有重点展现。语言结构形容词的比较级也沉浸在小学英语教材以及初一的教学内容中。本单元通过Personal traits这一话题既再现了已有语言项目，又把形容词比较级这一结构规范化，并对己有语言项目进行拓展，学生通过讨论选择何种个性朋友，提高认知、思维能力。 
第一课时全面展示本单元语言材料。通过几对双胞胎特征的比较展示本单元话题：I am more outgoing than my sister. 听力材料提供学生规范的进行比较运用的句型结构： …more … than …   … -er/ier than …

【教学过程】
一、导入（启发探究 6分钟）
1.compare different people and different things before class. How do we describe people? Let’s describe the following people.
（以2个明星（潘长江和姚明）为例，让学生尽可能多的复习描述人的形容词。）一起核对描述人的形容词 write and we can group them into some pairs like sectionA
2. Compare people.
(1) tall : Jim is taller than Tim .
quiet : Lucy is quieter than Lily , etc .
(2) late : Lucy was later for school than Lily .
free : Lucy was freer than Lily last weekend ,etc .
(3) heavy : Jim is heavier than Tim .
funny : Jim is funnier than Tim , etc .
(4) thin : Lucy is thinner than Lily .
big : This apple is bigger than that one . etc .
当A 和B做比较时时，用A +be +比较级+ than +B比较对象. 来表示。
如：My room is smaller than yours. 我的房间比你的小。
She got there earlier than I did. 她比我到得早。
（以句型示例带动学生认识做比较的句型，并描述图片“潘长江、姚明”。导入新课，并进一步联系句型。）

III、完成17页1c

2、在全班表演对话.
（语言的目的就是交流，训练学生运用重点句型与人交流的能力。）
四、总结（引深探究 15分钟）
形容词比较级的构成
1.直接在形容词后加-er。taller, shorter, quieter, calmer
2.以不发音的e结尾的形容词直接在其后加-r。cuter, nicer, finer, later
3.以重读闭音节结尾并且末尾只有一个辅音字母，应先双写这个辅音字母再加-er. bigger, fatter, thinner
4.以“辅音字母+y”结尾的，先改“y”为“i”，再加-er。funnier, easier, earlier
5.多音节和部分双音节形容词在其前面加more。 more outgoing, more beautiful
6.不规则变化
good/well—better—best bad/badly—worse—worst many/much—more—most
far—farther—farthest far—further—furthest little—less—least
口诀（chant）
比较级有规律,词尾加上-er两兄弟;
要是以e来结尾,只有小二(r)跟上去;
重读闭音节词要牢记,双写千万别忘记;
要是“辅音+y”来结尾,小艾(i)要把y来替,再加-er两兄弟;
多音节词加上more,你看这样多容易。
