八上Unit3辅导讲义【知识梳理1】1.形容词或副词比较级的构成2.形容词的原级和比较级形容词有三种形式：原级，比较级和最高级1. 形容词的原级即形容词原形形式，常用于very，so，quite，too之后；还用于句型as...as...(和……一样……)以及not so/as...as...(不如……)中。
The coat is too expensive.这件外套太贵了。
The boy isn't as/so old as the girl.这个男孩比这个女孩小。
2.形容词的比较级常用于两者之间进行比较，表示其中一个比另一个“更……”或“较……”，后用连词than连接另一个所比较的人或物。
在上下文明确的情况下，形容词比较级也可单独使用。
I'm more outgoing than my sister.我比我妹妹外向。
This book is old.Can you give me a newer one？这本书是旧的。
你能给我一本新的吗？记忆口诀1）形容词比较级规则规则变化记忆口诀：比较级，有变化，一般词尾加er；词尾不发音e简单化，之后另把r加。

双、多音节更容易，之前加more就可以。
（2）形容词比较级不规则变化口诀：“俩好”(good/well)是better；“俩多”(many/much)是more。

(1) 比较级一般在形容词后加_________, 如：tall—taller, short—shorter, old—older(2)以辅音字母+y结尾的双音节词，应该_______________________, 如：funny—funnier,heavy—heavier. 单音节词除外，如: shy— shyer(3)如果只有一个元音字母，并且后有一个辅音字母结尾，应该___________________________, 如：big—bigger, thin—thinner(4)多音节词的比较级，应该___________________, 如：outgoing—more outgoing,beautiful—more beautiful(5)不规则词的变化需要死记：good/well---___________; bad/ill--____________, many/much---_________;little---________; far--_______3.

如：Both you or I ______ right. ( be ) 你和我都是对的(2) either...or…表“要么…要么…”，连接两个主语时，谓语动词遵守就近原则。
如：Either you or I ______ right. ( be ) 要么你要么我是对的4. both表“两者都”，all表“多者都”题：_______ of my parents are teachers. We are ________ in China.5. play the drums 打鼓（乐器前要加the，drum要用复数，架子鼓不止一个）6. heavy (1)重的(2) 胖的，同义词为fat，反义词为thin.7. 反义疑问句：前面是陈述句，用来表达自己的观点，后面反问对方以证实自己的观点。
基本规律为前肯后否，前否后肯。
后面的附加疑问句的构成与改一般疑问句的方法相同。
如：①He isn’t a teacher, ___________ ? ②She can dance, _________ ?③He likes English, __________？(1)反义疑问句的回答根据事实用Yes或No来回答，但前否后肯的很容易出错，可改成一般疑问句或前肯后否再作回答。
如;He can’t sing, ___________ ? ( 如果他能，怎么回答)----- _______________(2) this, that 和表物的不定代词做主语，用it代替；表人的不定代词用they来代替。

如：There is litter water in the cup , __________ ?(4)反意疑问句的陈述部分含有由un-, im-, in-, dis-, 等否定意义的前缀构成的词语时，陈述部分要视为肯定含义，问句部分用否定形式。
如：Your father is unhappy, ___________ ?(5)反意疑问句的陈述部分为I don't think+ that从句时，从句为否定意义，问句部分的动词和主语仍与that从句保持一致且用肯定式。
如：I don't think that you can do it, __________? （不用do I?）(6)陈述部分为Let's……时，因为此句型用来提建议，所以问句部分习惯上用shall we?如：Let's go home together, shall we?(7)陈述部分为Let us……时，问句部分习惯上用will you?形式。
如：Let us stop to rest, will you?(8)陈述部分为祈使句，问句部分可以用will you和won’t you。
①Please open the window, won’t you? (肯定祈使句有时也可以用will you?提问)②Don't make any noise, will you? （否定祈使句只能用will you ?）Section A Page 181. 形容词和副词(1)形容词常译为“....的”。
①常放名词前，修饰名词，如：a good boy ②也可以放系动词后做表语，用来描述主语是怎么样的。
如：The boy is good.(2)副词常译为“…地”。
常放动词后，修饰动词，表“怎样地做某事”，很多副词以ly结尾，如do well；run fast；get up early；talk loudly；speak quietly.2. 以ly结尾的副词和形容词，一般前面加more 构成比较级，但early和friendly 例外。
如：loudly→more loudly，quietly →more quietly，early →earlier，friendly →friendlier3. 同级比较：表两事物是一样的，形容词和副词用原形。

)= Kate is taller than Jane. (Kate比Jane更高)3. the singing competition 唱歌比赛4. fantastic = great 好极了的It was fantastic/ great5. Which 用来问“哪一个”，回答常用“The + 名词+描述性短语”，如：________ one was Lisa ? ---- The one with shorter hair. ( A. Who B. Which C. What )6. win ( won )赢，后接比赛、名词、奖品做宾语，如：He won the game. He won the first place.7. 不定式可以放be 动词后做表语，表“….是去做某事”，如The most important thing is to learn something new. 最重要的事是去学新的东西。
Their dream is _________ a bridge. ( have )My job was _______ chickens. (feed)8. learn something new 学习新的东西（形容词放不定代词后）9. have fun = enjoy oneself = have a good time 玩得开心，过得愉快have fun doing sth. 在做某事中过得愉快We have fun ________ English.

The more we get together, the happier we’ll be. 我们越多的在一起，我们就越快乐。
(3) 修饰比较级的词有：a little, much, a lot, rather, even等，不能用very修饰比较级He is ______ taller than me. ( A. a few B. a little C. very D. many )(4) 两个相同对象进行比较，为了避免重复，常用that来代替前面的单数比较对象，用those来代替前面的复数比较对象。

(趣味性更少些)= English is ________interesting than math.(6) 在比较级中，the other 后接复数名词，表“其它的一些”；any other 后接单数名词，表“任何其它的一个”。
如：①I’m louder than the other ______ in my class. (kid)②I’m taller than any other _______ in my class. (student)(7) the + 比较级+of the two. (the用来特指“比较…的那一个”)He is ______ _______ of the two.
