Skillfully construct sentences using comparative and superlative forms in both written and oral communication. They will engage in conversations, role-plays, and writing exercises to describe people, objects, and experiences, making comparisons in daily situations. Analyze how comparative and superlative forms are used in authentic English materials such as English songs, movies, and stories, enhancing their understanding of English-speaking cultures. Learning objectives In this lesson, students will be able to: Grammar the comparative and the superlative adjectives 一般来说，中文意思是“……的”的词是形容词， 而中文意思是“……地”的词是副词。 用以修饰名词，表示事物的特征的词。 e.g. long, tall, short, cheap, hungry, etc. 什么是形容词？ He runs fast. Today is very hot. Please read it loudly. 用来修饰动词、形容词、其他副词、全句或名词词组及句子的词。e.g. very, early, quickly, etc. 什么是副词？ 什么是比较级？ 形容词比较级用于两者（人或事物）之间的比较，表示其中一个比另一个“更……”或“较……”，后面用连词than连接另一个所比较的人或事物。 “A + be +形容词比较级 + than + B” 意思为“A比B更……” 1.That ruler is longer than this one. 2.Mary is younger than me. 比较级注意事项 ① 在含有连词than的比较级中，前后的比较对象必须是同一范畴，即同类事物之间的比较 * 比较应在同类事物中进行. ②在比较级前面使用much，表示程度“强得多”。 如：A watermelon is much bigger than an apple. ③ very, quite一般只能修饰原级，不能修饰比较级。 最高级 形容词、副词的最高级形式主要用来表示三者或三者以上人或事物的比较，表示“最……”的意思。句子中有表示范围的词或短语，如：of the three, in our class 等。 如：He is the tallest in our class. 他在我们班里是最高的。 young–yonger–yongest old–older–oldest tall–taller–tallest early–earlier–earliest thirsty–thirstier–thirstiest 1. 一般情况下在形容词或副词后加-er（比较级） 或-est（最高级） : 2. 以字母e结尾的形容词，加-r 或-st 4. 以“辅音字母＋y”结尾的形容词，先改“y”为“i”，再加-er 或-est. big—bigger–biggest fat—fatter–fattest nice–nicer–nicest safe –safer–safest 3. 重读闭音节词只有一个辅音字母时，应双写辅音字母，再加-er或-est. 形容词比较级最高级变化规则 5.部分双音节词或多音节词前面加more, most. 如:interesting more interesting most interesting 不规则变化 原级 比较级 最高级 good/well better best bad/ill worse worst many/much more most little less least far farther/ further farthest/furthest old older/ elder oldest/ eldest 两好、两坏、两多、 一少、一远 、一老 (1)A+be+比较级+than+B e.g. Mary is much younger than Sue.
