Show two colums of words, and ask students to match these Adjective and Advervbs with their comparative forms.(利用PPT展示两栏词语，引导学生读出这些单词，将形容词及副词与其比较级相匹配。) 2. Ask students to find out the differences between the two colum words and try to find the rules.(找不同，找规律) 3. Teachers can give some help to the students(通过指出一些形容词及副词比较级的变化，帮助学生找到变化规律) Tall Heavy Lazy Big Good/well Many/much Outgoing Difficult Easily Beautifully More Bigger More difficult Taller More outgoing Heavier Better More easily More beautifully Tall---taller(直接加-er) Big---bigger( 双写最后一个辅音字母加-er) Heavy---heavier(变y为i加-er) Lazy---lazier(变y为i加-er) Outgoing---more outgoing Difficult---more difficult Easily---more ealisly Beautifully—more beautifully 结论： 形容词与副词的比较级的构成： （1）规则变化 构成方法 原级 比较级 一般加-er Tall Short long Taller Shorter longer 以e结尾的词加-r nice large late Nicer Larger later 以“辅音字母+y”结尾的词，改y为i，再加-er Heavy Easy happy Heavier Easier happier 以重读闭音节结尾，双写辅音字母，再加-er Thin Big Fat hot Thinner Bigger Fatter hotter 多音节形容词和部分双音节形容词构成比较级时，在前面加more Outgoing Friendly loudly More outgoing Friendly loudly (2)不规则变化 原级 比较级 Good/well better Bad/badly/ill worse Many/much more little less far Farther further 完成下列句子： (1)他们的书比我们的多。 They have _____ ______ ______us.

Does Tara work as hard as Tina? Yes,she does. Who’s more hard-working at school?
