(表语) 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: 即原级、比较级和最高级。当讨论
12、的对象是一个时应使用原级，当讨论的对象是两个时应使用比较级，当讨论的对象在三个或更多时应使用最高级。（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，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。e.g. His hair is longer than his fathers. = He has longer hair than his father. Its hotter in Shanghai than in Beijing. China is bigger than any other country in
13、Asia.（2）形容词比较级的构成： 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 many / much- more - most（3） 在形容词比较级前还可用much, even, a little来修饰e.g. This city is much more beautiful than before. Shes a lit

( 6 ) 两个人或物比较时，如果只说明两者相同或不同，则可使用as.as.句型， 否定句为not as (so).as.句型，这里形容词仍使用原级。如：Mr.
15、 Green is as old as Mr. Brown. Mr. Green is not as (so) old as Mr. Brown.四。单元知识点讲解：1. Here are the photos of me and my sister Liu Ying .

17、is shorter than hers. （1） both“两个、两者都”，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）= His parents are both doctors. （作副词）They both went camping in the holiday. （作副词） both and e.g. Both English and math are very important. 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
18、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。 e.g. There are some differences, though. 固定短语是even though表“即使、纵然”，不能用even although. （3）hers名词性物主代词，句中指“her hair”. 4. She has more than one sister. 她不止有一个姐姐。 more than “超过”比较morethan.“比多” e.g. He has more books than me .5. They have some
19、 things in common. （in common共通（同）的）比较：something某物（不定代词）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）asas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”e.g. He runs as quickly as his father.
