Step1 Warm up 1.Greetings 2.Let’s have a chant.Step2 Presentation and drills 1.Leading—in (课件出示刘翔和姚明的照片)
T: Do you know the two men? Who are they? S:Yes.They are Liu Xiang and Yao Ming.T:Very good.Can you describe them? S:Liu Xiang is tall.T:Yao Ming is taller than Liu Xiang.Liu Xiang is shorter than Yao Ming.引出形容词的比较级。 2.Sum up the rules.形容词加er的规则:
①一般的直接在词尾加er ,如tallstronger , ②以e结尾的,直接加r ,如finefunnier ④以结尾,双写最后的字母再加er, 如big--bigger, thin--thinner ,hot–-hotter,sad--sadder,
⑤另外多音节词,在多音节词前加more
如:beautiful--more beautiful expensive--more expensive 除此之外,还有特殊的单词,它的比较级不规则。如:
good/well(原形)- better(比较级)bad /ill(原形)- worse(比较级) many / much(原形)- more(比较级) little / few(原形- le(比较级)
far
(原形)-- further/farther Old (原形)--- older/elder(比较级) 3.Recite 我们知道了比较级的变化规则。请熟记比较级变化口诀 两者之间做比较,尾巴er少不了。 一般词尾加er,有e词尾只加r.单一辅音单音节,双写词尾加er.辅音加y很重要,改y为i加er.双多音节字太长,前加more比它强。
不规则变化要记好,两个好、两个坏、两个多、两个少、一个遥远、一个年老。 4.drills 一般句式的构成: A + is / are+ 形容词比较级+ than + B A 是主格 B 是宾格
如: She is taller than me.主格 形容词比较级 宾格
