Unit 6 I’m more outgoing than my sister.一. [话题] (Topic) Talk about personal traits.Compare people.二. [重点词组] (Key Phrases)1. 形容词比较级:taller, shorter, thinner, longer, heavier, calmer, wilder, quieter, funnier, smarter, more athletic, more popular2. more, than, twin, both,3. twin sister, look the same, look different, go to parties, in common,be good at, make sb. do sth, elementary school, enjoy doing sth.,三.

His life style is quite different from ours.The twin sisters look the same.We read the same book as you showed us last time.2. I’m funnier than Tara. And I’m more outgoing.(1)形容词比较级用法:形容词比较级用法用于两者之间的比较,表示一方比另一方“更…”或“较…”,后常跟比较连词than表被比较的对象。
为避免重复than引导的从句中有些与主句相同的部分常省略,而把相比较部分突出。
另外,在上下文中,形容词比较级也可单独使用。
注意:than后常跟名词,但这是由于than引导的比较状语从句省略了与主句相同的部分。
在进行比较时,一定要注意比较对象要对等。
e.g. His hair is longer than his father’s.= He has longer hair than his father.It’s hotter in Shanghai than in Beijing.China is bigger than any other country in Asia. (any other “任何一个”)(2)形容词比较级的构成:形容词分原级、比较级、最高级。
通常形容词的比较级为规则变化,在词尾加-er,以不发音的e结尾的单音节词和少数以-le结尾的双音节词直接加-r,(以辅音加y结尾的变y为i加-er,重读闭音节以辅音字母结尾的双写结尾的辅音加-er)。
有的双音节和多音节的词,在词前加more构成比较级。
此外还有个别词为不规则变化。
例:good / well - better / best, bad / ill - worse - worst, little - less - least,old - older / elder - oldest / eldest, many / much- more - most, far-farther / further-farthest / furthest(3)在形容词比较级前还可用much, even, still, a little来修饰,表示“…的多”“甚至…”“更…”“…一些”。
e.g. This city is much more beautiful than before.She’s a little more outgoing than me.It’s a little colder today.(4)“比较级+and+比较级”意为“越来越…”注:多音节比较级用“more and more+形容词原级”形式。
It’s getting worse and worse.The group became more and more popular.(5)“Which / Who is + 比较级…?”比较A、B两事物,问其中哪一个较…时用此句型。
e.g. Which T-shirt is nicer, this one or that one?Who is more active, Mary or Kate?Which one is more popular among students, going to concerts or going tomovies?3. As you can see, in some ways we look the same, and in some ways welook different.“look the same”看上去一样。
“look like…”看上去像…,look alike看上去相像in a way为某一种方式此处look系动词,后跟形容词。
例:look young / old / tired / nice.4. We both have black eyes and black hair, although my hair is shorter than hers.(1)both“两个、两者都…”,在句中可作代词、形容词、副词、连词。
作副词时常放在be动词之后,实义动词之前。
e.g. Both (of)his parents are doctors. (作代词或形容词)=His parents are both doctors. (作副词)They both went camping in the holiday. (作副词)Both English and math are very important.(both …and…短语常连接两个并列的成分,可连接名词、动词、形容词和代词等。
)注:both指两者都,all指三者或三者以上都。
(2)although与though常可互换,表“虽然、即使、尽管”,都不能与but用于一句话中。
但though用得更普遍。
此外though可作副词,在句尾表“然而”,although不能。
固定短语是even though表“即使、纵然”,不能用even although.e.g. There are some differences, though.(3)hers名词性物主代词,句中指“her hair”.5. She has more than one sister. 她不止有一个姐姐。
They have some things in common.(in common共通(同)的)(something某物,some thing某一个事物,some things一些事物)6. Li Ying is not as good at sports as her sister.(1)as…as…同级比较,两个“as”之间必须使用形容词或副词原级。
意为“如同……一样…”,not as / so …as“不如…一样…”e.g. He runs as quickly as his father.The watermelon is as big as a soccer ball.She doesn’t study so / as hard as her brother (does)(2)be good at sth. / doing sth. 擅长于(做)某事。
e.g. They are good at playing badminton.I’m not good at painting.Who is good at computer in your class?7. I think a good friend makes me laugh.make sb. do sth. 让(使)某人做某事(make后跟不带to的不定式)e.g. His words made us feel so exciting.The boss made the workers work all day and all night.8. She’s a good listener, and she keeps secrets.听者listener, 说话者speakerkeep a secret保密9. Is she a lot like you? = Is she like you very much?(1)a lot 表程度,相当于very much,但位置不同。
(2)be like 像…,like为介词。
10. primary school小学secondary school小学,high school中学middle school中学11. enjoy sth. / doing sth. 喜欢(做)某事(物)enjoy telling jokes, (tell a joke讲笑话)12. I think she should get the job.should 情态动词,“应当、应该”,后跟动词原形。
We should study hard and be good students.You should help your mother with the housework.五. 语法知识1) 形容词的作用形容词在句子中一般充当表语、定语和宾语补足语,如:Our school looks very beautiful. (表语)There are fifty students in our class, so we need a big classroom. (定语)Doing morning exercises can make us healthy. (宾语补足语)2) 形容词的级别形容词有三种级别,即原级、比较级和最高级。
