Section A Page 17 1. 两个事物进行比较可以用形容词或副词的比较级表达：
(1) A + be+ 形容词比较级+ than +B (A比B更… ) Jane is taller than Kate. (2) A + 动词+ 副词比较级+ than +B (A比B更… ) Jane runs faster than Kate. 2. 形容词的比较级的构成。
(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. (1) both….and…. 表“两者都”，连接两个主语时视为复数。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：
① He isn’t a teacher, ___________ ?
② She can dance, _________ ? ③ He 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。
Something is wrong, __________ ? Everyone likes English, _____________ ? (3)反意疑问句的陈述部分带有little, few, never, hardly, seldom等否定意义的词时，问句部分用肯定式。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 ?）
1. 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 →friendlier 3. 同级比较：表两事物是一样的，形容词和副词用原形。
(1)A +be +as +形容词原形 + as +B ( A和B是一样地…) Jane is as tall as Kate. (2)A +动词+as +副词原形 + as +B ( A和B做某事一样地…) Tara works as hard as Tina. (3) not as…as = not so…as表“不如...”, 常可以与比较级转换。如：
Jane is not as/so tall as Kate. (Jane不如Kate高。) = 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/ great 5. 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. ( learn ) 二、重点句子 1.He has shorter hair than Sam. 他的头发比萨姆的短。
than 比……（用于形容词，副词的比较级之后）
当两个人或者物进行比较时，要用形容词的比较级。“比较级 + than” 表示“比......更......”。一般形容词或副词的比较级是在词后加-er。但要注意比较的对象。如：
I am taller than Jim. 我比吉姆高。
His hair is shorter than Sam’s. 他的头发比萨姆的短。
This book is more interesting than that one.这本书比那本书有趣。
形容词和副词的比较级、最高级 大多数形容词和副词有三个等级：1）原级（不作比较），修饰词very,so,too,pretty,really；
2）
比较级，表示“较……”或“更……”的意思（两者之间进行比较）, 标志词than,A or B,of the two, 修饰词much,a lot,a little；
3）
最高级，表示“最……”的意思（三者或三者以上作比较），形容词最高级前面一般要加定冠词the，后面可带in（of）短语来什么比较的范围。
形容词和副词的比较级和最高级规则变化：
构 成 方 法 原 级 比 较 级 最 高 级 单音 节词 和部 分双 音节 词 一般在词尾加-er或-est high short higher shorter highest shortest 以字母e词尾的词，加-r或-st late fine later finest latest finest 重读闭音节词词尾只有一个辅音字母时，先双写辅音字母，再加-er或-est hot big thin fat hotter bigger thinner fatter hottest biggest thinnest fattest 以“辅音字母+y”结尾的双音节词，先把“y”改为“i”，再加 -er或-est funny easy early funnier easier earlier funniest easiest earliest 多音节词和部分双音节词 在词前加more或most beautiful athletic outgoing more beautiful more athletic more outgoing most beautiful most athletic most outgoing 形容词和副词的比较级和最高级不规则变化：
原 级 比较级 最高级 good/well better best bad/badly worse worst many/much more most little less least far farther（更远）
further（更深远）
farthest(最远) furthest（最深远）
2. 反意疑问句 ①肯定陈述句＋否定提问 如：Lily is a student, isn’t she? Lily will go to China, won’t she? ②否定陈述句＋肯定提问 如：She doesn’t come from China, does she? You haven’t finished homework, have you?
③提问部分用代词而不用名词如：Lily is a student, isn’t she?
④陈述句中含有否定意义的词，如little, few, never, nothing, hardly等。其反意疑问句用肯定式。
如：He knows little English, does he? 他一点也不懂英语，不是吗？ They hardly understood it, did they? 他们几乎不明白，不是吗？ 3. No,I am a little taller than her. a little, much a lot a bit ,far,any,no等可以+比较级 4. Tara works as hard as Tina. 塔拉学习跟蒂娜一样努力。
“...（not）as + 形容词或副词原级+ as...”是一种原级比较，意思为“......和......(不) 一样”。
1）
...not as + 形容词或副词原级+ as...表示双方在某个方面不同。如：
His English is not as good as hers. 他英语不如她的好。
He doesn’t work as hard as his brother. 他没有他哥哥工作努力。
2）
as + 形容词或副词原级+ as 表示双方在某个方面一样。如：
She is as tall as me. 她跟我一样高。
I run as fast as he does. 我跑得跟他一样快。
1. 比较级的几种特殊用法：
(1) “比较级 + and + 比较级”或“more and more +多音节词”表示“越来越……” 如：① warmer and warmer ② more and more beautiful. (2) “the +比较级+句子, the+比较级+句子”，表示“越……，越……”。
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。
The weather in Beijing is much colder than that in Hubei. （that=the weather）
The trees are greener in the country are much greener than ________in the city. (5) less与more 的转换：
Math is less interesting than English. (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：① I’m louder than the other ______ in my class. (kid) ② I’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. ( tall ) 2. hard-working勤奋的；

truly副词，真地，truth名词，事实 ①That’s_________. ② He _______ cares about me. ③Tell me the ________. 4. care about 关心，在乎 Nobody cares about me. take care of = care for = look after 照顾 I can take care of myself. 5. 使令动词有：make, let, have，它们都可以表“使、让某人做某事”，使令动词后接动词原形，即：make/ let/ have sb do sth. 如：
①It makes me ______ . (laugh) ②Let me ______ you. (help) ③He had her ______ there. ( go ) 6. laugh at 嘲笑某人 It’s not good to laugh at others. 1. be like 像；
look like 看起来像（强调外表）
The teacher ____________ my mother to me. 2. be serious about 对…是严肃认真的 I’m serious about that. 3. do sth. together 一起做某事 We enjoy studying together. 4. 句型：It’s + 形容词+ （for sb.）+ to do sth. 表“（对于某人来说）去做某事是…的”。
It’s not easy for me __________friends. ( make) It’s not necessary to be the same. 【总结】it是形式主语，它代替后面的不定式短语。
5. make friends with sb. 和某人交朋友 I want to make friends with you. 6. as long as 只要 As long as you study hard, you’ll get good grades. 7. be the same as “与…一样”，be similar to “与…相似”，be different from “与…不同” 题：His eating habits aren’t the same as mine. = Her eating habits are mine. 8. bring out the best in me 我最好的方面表现出来 9. be/get good at 擅长，be better at 更擅长，get better at 变得更擅长 I’m getting better at tennis.
