片头 Teacher：“Hello everyone, welcome to my English class！” Before our class, I would like to introduce myself to you. I used to be a little short. Now I'm tall. I'm taller than before. I used to be a shy girl. I'm very outgoing now. I'm more outgoing than before. I used to be afraid to talk to people. Now I enjoy being with others. I'm more popular than before. After this class, I hope you can introduce yourself like me. So,today, we will learn a new grammar named The Comparative Degree of Adjectives and Adverbs. Let's start!
正文讲解 Teacher：Today, we are going to learn The Comparative Degree of Adjectives and Adverbs. First of all, look at the following sentences. Can you find the similarity between these sentences 1.I'm taller than before. 2.I'm more outgoing than before. 3.I'm more popular than before. Students: There is a “than” in these sentences. Teacher：Clever! 我们今天学习的是形容词和副词的比较级结构, 大家刚刚找到的“than”是形容词和副词比较级的标志词，意为：“比”。 Teacher：So when do we use comparatives Just now, I have introduced myself to you. We can find it is used to describe the changes in one person. Besides, it can also be used to describe the differences between two persons. Now I'd like to introduce two students in our class. They are Mary and Tina. 1.Mary has longer hair than Tina. 2.Tina is a little smarter than Mary. 3. Teacher thinks Mary works harder than Tina. Teacher：Please find out the comparative degree of adjectives and adverbs in the three sentences. Students: longer,smarter, harder. Teacher：All right! What are the positive degree of the three words Students: long,smart, hard. Teacher：一般情况下，直接在形容词或副词的原级加er变成比较级。 Look at these words and read after me: long-longer, smart-smarter, hard-harder, quick-quicker, fast-faster, tall-taller, short-shorter. Teacher：There are some differences between Mary and Tina. Let's take a look together. 1.Tina gets up later than Mary. 2.Mary's schoolbag is larger than Tina's. 3.Learning English is simpler for Tina. Teacher：What are the positive degree of the three adjectives and adverbs Students: late, large, simple. Teacher：以不发音的字母e结尾的单词，在词尾加上-r即可。Read after me. late-later, large-larger,simple-simpler,close-closer, nice-nicer. Teacher：Let's look at some more sentences. Mary gets up earlier than Tina.. Tina is lazier than Mary. 3. Tina is funnier than Mary. Teacher：这三个形容词或副词的原级是early,lazy 和 funny. 他们都是以哪个字母结尾的呢？倒数第二个字母是元音还是辅音。 Students: 字母y结尾，倒数第二个字母都是辅音。 Teacher：大家观察，这些形容词，副词是怎么变成比较级的呢？ Students: 变y为i加es. Teacher：实际上，以“辅音字母+y”结尾的词，先变y为i再加-er. easy-easier, lazy-lazier, funny-funnier,busy-busier, tidy-tidier, happy-happier,. Teacher：Let's look at the three sentences. 1.Tina is fatter than Mary. 2.Mary is thinner than Tina. 3. Tina's dog is bigger than Mary's cat. Teacher：Can you find the difference between fat and fatter, thin and thinner, big and bigger Students: Double t or n plus er. Teacher：以一个辅音字母结尾的重读闭音节,双写最后一个辅音字母，再加-er. For example: fat-fatter, thin-thinner,big-bigger, hot-hotter, slim-slimmer, fit-fitter. Teacher: Mary and Tina took part in the singing contest yesterday and they all did very well. Let’s take a look. 1. Mary is more popular than Tina. 2.Mary sings more loudly than Tina. 3.Tina is more outgoing than Tina. Teacher: popular, loudly,outgoing这三个单词相对来说更长，他们的音节也更多。实际上，部分双音节词和全部多音节词不会在原来的单词上变化，而是在单词前加more构成比较级。 Now read after me. popular- more popular，loudly-more loudly, outgoing- more outgoing, beautiful- more beautiful, important- more important. 我们可以发现，上面涉及到的变化都是有规律的，大家来和老师一起总结。1.一般情况，直接加er。例如：long-longer, smart-smarter, hard-harder 2.以不发音的字母e结尾的单词，在词尾加上-r即可。例如： late-later, large-larger,simple-simpler. 3.以一个辅音字母结尾的重读闭音节或者说以辅音元音辅音结尾的单词,双写最后一个辅音字母，再加-er. 例如: fat-fatter, thin-thinner,big-bigger. 4.一部分双音节词或者全部多音节词，不在原来的单词上变化，而是在单词前加more变成比较级。 popular- more popular，loudly-more loudly, outgoing- more outgoing. 跟着节奏，和老师一起记忆下面的口诀。 1.直接加er，有e只加r 2.结尾辅元辅，双写尾字母 3.词尾辅音y，把y变成i 4.遇到多音节，more往前面写 除了规则变化，形容词，副词变比较级时还有不规则变化。看这三个句子。 1.Both Tina and Mary can play the drums, but Tina plays them better than Mary. 2.Tina goes further than Mary to school every day. 3.Mary's brother is elder than Tina's brother. 像good-better，far-further, old-elder这类比较级的变化是没有特殊规律的，下面的表格中还有一些单词是不规则变化的，大家下课后需要自行反复记忆。 原级比较级good,wellbetterbad/badly/illworsemany/muchmorelittlelessfarfarther/furtheroldolder/elder
Practice makes perfect. Let’s do some exercises. 1.My mooncake is nicer__D_____ his. A. like B. with C. for D. than 1.Choose D than. 我的月饼比他的更好看。两者之间做比较，用比较级。 应该选择than。 2.The pen is___B____ than that one. A. cheap B. cheaper C. cheapper D. cheapest The pen is cheaper than that one. 这一支钢笔比那一支更便宜。 cheap 变成cheaper 直接加er。 3.You have more rulers than me. But my rulers are ___A____ than yours. A.nicer B.more nice C.niceer D. nicest 我的尺子比你的尺子更好看。nice以不发音的e结尾，直接加r变比较级。 4.Which is___B____ , a bicycle or a computer A. expensive B.more expensive C.the most expensive D.expensiver expensive 是多音节词，前面加more变成比较级，这个题选B more expensive。 5.He jumps__B_____ of the three. A. far B. further C. farthest D. furthest 这个题选择B选项，这个男孩比女孩跳得更远。 far变成比较级是不规则变化，变成further Jessica is much_______ than Jason. thiner B. thinr C.thinner D.thin Look at the picture. Jessica is much thinner than Jason. thin以辅元辅结尾，双写尾字母n加er，thin变thinner
