more afraid, most afraid tired - more tired , most tiredfond - more fond , most fond glad - more glad , most gladbored - more bored , most bored pleased- more pleased , most pleased下列形容词和副词的比较级和最高级有两种形式，即：既可加-er/-est也可加more/mostcruel, strict, often, friendly, clever下列形容词和副词没有比较级和最高（即表示“最高程度”或“绝对状态”的形容词和副词没有比较级和最高级）empty, wrong, perfect, unique, extreme, excellent, favourite, true, right, correct, extremely .形容词副词比较级最高级使用注意事项比较应在同类事物之间进行。误：Your English is better than me.正：Your English is better than mine.比较级前可以有一个表示程度的状语，最常见的三大修饰词是：a little, much, even。以下单词也可用来修饰：any, far, still, a lot, yet, rather。My sister is a little taller than me.Their house is much larger than ours.另外，名词短语也可修饰比较级，说明程度。Im three years older than he.特别提醒：very, quite, too不可修饰比较级。避免重复使用比较级。误：He is more kinder to small animals than I.正：He is much kinder to small animals than I.误：He is more cleverer than his brother.正：He is cleverer than his brother.比较要遵循前后一致的原则，注意前后呼应。The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out.序数词通常只修饰最高级。Africa is the second largest continent.The Yellow River is the second longest river in China.This is the third most popular song of Michael Jackson.形容词副词比较级最高级重点句型归纳句型一：形容词或副词比较级+than注意事项：该句型为比较级的最基本句型。只要看到than，即可确定前面使用比较级。He is taller than I am.The boy does his homework more carefully than the girl.句型二：less + 形容词的原级 + than注意事项：该句型表示“不如、不及”，特别需要注意的是，less本身就是little的比较级，后面必须跟形容词的原级，否定就造成了比较级的重复使用。This puter is less expensive than that one.句型三：as +形容词或副词的原级+ as注意事项：该句型表示对比的两者程度相当，as之间必须跟形容词或副词的原级，决不能使用比较级。此外，还要确定使用形容词还是副词。确定的依据就是根据第一个as前的动词，如果是系动词（如be，感官动词look, sound, smell, taste, feel等），那么就用形容词的原级，如果前面的动词是一般的实义动词，那么就必须用副词的原级修饰动词。This lesson is as easy as that one.Lucy talks with old people as politely as her sister.特别提醒：asas之间也可以跟名词，句型如下：as +形容词+ a/an +单数名词+as He is as kind a person as his father. 他和他爸爸一样都是善良的人。as + many/much+不可数名词/可数名词复数+as I can carry as much paper as you can. 你能搬多少纸，我也能。 I have as many books as you do. 我的书和你的一样多。 Well give you as much help as we can. 我们将尽我们所能给你帮助。其它几个关于asas的句型：as as one can：尽其所能 He began to run as fast as he could. as as possible：尽可能Please helpusas quickly as possible. as soon as一就 He will call me as soon as he es here.句型四：not as/so +形容词或副词的原级+ as注意事项：该句型表示“前者不如后者”，往往可以与句型一和句型二替换。第一个as可以换为so。This classroom is not as bright as yours.I cannot run as fast as you.句型五：the +形容词或副词最高级+ in / of / among +比较范围注意事项：如果这里为副词最高级，前面的the常常省略。介词in和of的用法完全不一样。in表示“在某一范围内”，如：in the classroom，in the world。of表示“在同类之间”，of后面的词与主语同类，另名词前一般有冠词the。among表示“在（三者或三者以上）之间”，among后接代词或没有修饰语的名词。The Changjiang River is the longest river in our country.Peter is the tallest of the six students.This picture is the most beautiful among these.句型六：one of + 形容词最高级+可数名词复数形式注意事项：one of有三大考点：1. 后跟形容词最高级；2. 后接可数名词复数形式；3. 作主语时主语为one，谓语动词用单数形式。One of the smallest dinosaurs was about one metre long.句型七：比较级+and +比较级 / more and more +多音节词的原级注意事项：该句型表示“越来越”，如果该形容词比较级构成形式加er，则用前面的句型；如果该形容词比较级加more构成，则用后面的句型。It is getting hotter and hotter.The girl is being more and more beautiful.句型八：the +比较级+, the +比较级+注意事项：该句型意思为“越就越”，表示两种情况同时变化。The more you eat, the fatter you will be.In the test, the more careful you are, the fewer mistakes you will make.句型九：be different from注意事项：该句型没有运用比较级，但也是对两者事物进行比较。注意前后比较需在同类事物中进行。My schoolbag is different from yours.句型十：the same as / the sameas注意事项：该句型同样没有运用比较级，表示两者之间具有共同特性。注意这里的as和same为固定搭配，不能随便变换。I dont want to buy the same things as Amy did. 句型十一：比较级+than + any other +名词单数形式注意事项：any other 后面跟单数名词，表示“任何别的”，即主语在范围内，必须把自身从这一范围内除去，否则逻辑上不通。如果主语不在这一范围内，那么要把other去掉，只用any即可。Shanghai is larger than any other city in China. （上海在中国这个范围内，所以用any other）Shanghai is larger than any city in Jiangsu. （上海不在江苏，所以只需用any）句型十二：比较级+than + the other +名词复数形式注意事项：该句型相当于any other +名词单数形式，常用来进行同义句改写。该句型与句型十一虽然波表面上都是比较级，但实际上相当于最高级。以下三句表达的是同一个意思。Daniel is the most hard-working student in our class.Daniel is more hard-working than any other student in our class.Daniel is more hard-working than the other students in our class.特别提醒：表示两者(人或物)比较时，比较的对象应是同类事物，不同类的事物之间无法进行比较。形容词比较级最高级练习题一、写出下列形容词和副词的比较级形式。1. long_ 2.tidy_ 3.hot _4. large_ 5.thin_ 6.good_7. bad _ 8.little_ 23. thin _ _10.much_11.early_ 12.fast _13.hard _14.difficult_15.badly_16.far_17.carefully_20.often_21. old _ _22. busy _ _24. many _ _25. slow _ _ 二、用形容词的适当形式填空：1.Bob is_( young )than Fred but_(tall)thanFred.2.

There is a desk in the classroom. 在教室里有一张桌子。(2) There are + 复数名词+ 地点状语. E.g. There are 5 apples in the box. 盒子里有五个苹果。口诀：“有” 字放前面，有“啥”放中间； 时间地点放后面；单数is, 复数are；注意be的两变化。4、句型变化：(1)、否定句：there be的否定式通常在be后加not。E.g. There is a bike under the tree. 树下有一辆自行车There isnt a bike under the tree.E.g. There are 2 little girls in the room.在房间里有两个小女孩。 There arent 2 little girls in the room.(2)、一般疑问句及其答语：1、一般疑问句：把be动词提前,首字母大写,句末用问号即可。2、回答时，“用什么问，就用什么答”，用Is / Are there来提问，就用there is / are来回答。肯定回答：Yes, there is / are. 否定回答：No, there isnt / arent.E.g. 1、There are two cats in the tree.树上有两只猫。Are there two cats in the tree? Yes, there are. No, there arent.2、There is a puter on the desk . 在桌子上有一台电脑。Is there a puter on the desk？ Yes, there is. No, there isnt.课堂练习：1. There is a new bed and an old desk in the room .否定句：一般疑问句 ：否定回答 ：5、some和any在“there be”句型中的用法：some 一些（some用于肯定句） any 一些（any用于否定句和一般疑问句）注意：There be句型在变成否定句或一般疑问句时，要注意把句中的some变成any。E.g.1、There is some water in the bottle .在瓶子里有一些水。There isnt any water in the bottle.（否定句） Is there any water in the bottle？（一般疑问句）2、There are some children in the picture. 图片里有一些小孩。There arent any children in the picture. （否定句） Are there any children in the picture？（一般疑问句）课堂练习：1. - Are there _ shops near here? - No, there are _ shops near here.A. some, not B. some, any C. any, not D. any, no2There are some tables on the floor.（变为否定句）6、就近原则：若句子中有几个并列的主语时 be的形式要与离其最近的一个主语在人称和数上保持一致。E.g. 1.There is a pen, two pencils and some books on the desk. 书桌上有一支钢笔、两支铅笔和一些书。2.There are two pencils, a pen and some books on the desk. 书桌上有两支
