Teaching Procedures	Tips
Step 1 Lead in
Show Ss three different pictures: a forest in 2009 and 2019, a polar bear in 2009 and 2019, a city in the past and today. T can ask Ss to make comparison of each picture. T may encourage Ss to make comparison from different aspects and the answers will vary. Revision Ask Ss to choose the correct comparative degree for each word. Answers: tall-taller, heavy-heavier, lazy-lazier, big-bigger, good/well-better, many/much-more, outgoing-more outgoing, difficult-more difficult, easily-more easily, beautiful-more beautiful. Ask Ss to sing a chant about comparative degree.
Step 2 Presentation & Practice
Grammar Focus Ask Ss to read the sentences in Grammar Focus. Ask them to underline the adjectives and circle the adverbs. Tell Ss that adjectives usually go with the verb be, adverbs modify the verbs and it usually go after the verbs. 3a Ask Ss to use the words to write questions and answers. Answers: 2. Does Jack run as fast as Sam? No, he doesn’t. He runs faster than Sam. 3. Is your cousin as outgoing as you? No, she isn’t. She’s more outgoing than me. 4. Is Paul as funny as Carol? No, he isn’t. He’s funnier than Carol. 3b Ask Ss to think of themselves two years ago. Write about how they are different now. Answers will vary. 3c Ask Ss to compare their parents. Check who is smarter, funnier, etc. Then ask Ss to ask their partner about his/her parents. Answers will vary.
Step 3 Language points learning
形容词和副词的比较等级 大多数形容词和副词有三个等级： 1. 原级，即原形。e.g. good, fast, outgoing ... 2. 比较级，表示“较......” 或“更......一些”。 e.g. better, faster, more outgoing ... 3. 最高级，表示“最......”。 e.g. best, fastest, most outgoing ... 比较级构成的规则变化 单音节词和部分双音节词: 一般在词尾加-er, 以字母e结尾的词加-r , 重读闭音节词词尾只有一个辅音字母时，先双写该辅音字母，再加-er, 以“辅音字母+y”结尾的双音节词，变“y” 为 “i”，再加-er。 多音节词和部分双音节词在其前面加more。 比较级构成的不规则变化 good / well-better, bad / badly-worse, many / much-more, little-less, old-older / elder, far-farther / further 易混淆辨别 older与elder的区别在于：old是形容词，表示“更老；更旧；年纪更大”，一般用来形容人、动物或物体（不限于形容家人），常与than连用。它不表示职务、地位和资历，也更口语化。elder既可以作形容词也可以作名词，表示“年龄更大”（但不一定是更老）一般只形容人，尤其是家人。它不与than连用，可表示职务地位资历更高，也更正式。 farther与further的区别在于：farther表示距离上更远; further即可表示距离上更远，也可表示程度上或抽象意义上的更深远或更进一步; further还可作动词，表示“促进；增进”。 比较级的常用句型有： 比较级+than，例如： A + be + 形容词比较级 + than + B A + 实义动词 + 副词比较级 + than + B “the + 比较级 + of the two” 意为 “两者中比较......的”。 “比较级 + and + 比较级” 或 “more and more + 形容词/副词原   级”，表示 “越来越……”，其后均不可接than。 “The + 比较级, the + 比较级” 意为 “越……，越……”。 “Which/Who... + 比较级, A or B?” 表示 “A和B，哪一个/谁 更……？” “A...+ 倍数 + 比较级 + than + B” 表示 “A是B的多少倍”。 “比较级 + than any other + 可数名词单数” = “比较级 + than the other + 可数名词复数”，表示“比其他任何/所有……都……”。该句型在同一范围内进行比较。 “比较级 + than any + 可数名词单数”，意为 “比任何......都”，表 示不在同一范围内比较。 “否定 + 比较级”，意为 “不能更......”或“再......不过了”，表示最 高级的意思。 可以修饰比较级的词： 当表示一方超过另一方的“程度”时，可以用much, a lot, a little, a bit, even, far等来修饰形容词比较级。注意：比较级不能用very, so, too等修饰。 比较级的注意事项： 比较对象必须一致。2. 有时为了避免重复，可用that或those代替前面提到的词，而且that或those不能省略。3. as...as用来进行同级比较，中间要用形容词或副词的原级。as ... as的否定结构是not as / so...as，意为“不如......那样......”。同级比较用原级，as ... as永不离。若是否定加not，后者总是强前者。
Step 4 Summary & Homework
Summary Ask Ss to do the exercises from PPT P27-30. Homework Review and recite the usage of comparatives. Preview the new words and phrases in Section B (1a-1e).
Teaching Reflection	In this period, first, let students read the grammar and review what they have learned. Then, give students the chances to compare their parents by using the target language. This task not only helps the students master the target language and expand their vocabulary, but also lets them understand their parents more.
