6、hinnesthothotterhottestbigbiggerbiggest 特別提醒：new, few, slow, clean等詞含有字母組合，且發(fā)的是長元音，不用雙寫。大部分雙音節(jié)詞和多音節(jié)的詞(即音標中含有三個或三個以上元音音素的詞)，要在前面加 more，most原級比較級最高級beautifulmore beautifulmost beautifulimportantmore importantmost importantinterestingmore interestingmost interestingexpensivemore expensivemost expensive

7、popularmore popularmost popular特別提醒：以形容前綴un構(gòu)成的三音節(jié)形容詞不適合上述情況，如unhappy-unhappier-unhappiest,untidy-untidier-untidiest以形容詞+ly構(gòu)成的副詞要在前面加 more，most原級比較級最高級slowlymore slowlymost slowlyquicklymore quicklymost quicklyangrilymore angrilymost angrilysoftlymore softlymost softlynoisilymore noisilymost noisily特

9、littlelessleastfarfarther/furtherfarthest/furthestoldolder/elderoldest/eldest特別提醒further不僅可以指“距離更遠”，還可指“程度更深”。記住以下三個詞組：further study(進修)further education(繼續(xù)教育)further information (進一步的信息)elder僅用于同輩之間的排行，如: elder sister(姐姐) elder brother (哥哥)less作為“更少”僅用來修飾不可數(shù)名詞，修飾可數(shù)名詞表示“更少”要用fewer。以下內(nèi)容不作為初中英語教學內(nèi)容，僅供

10、拓展之用。少數(shù)單音節(jié)詞前面加 more, most 構(gòu)成比較級和最高級，這類形容詞一般為表語形容詞和由過去分詞變成的形容詞。afraid - 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下列形容詞和副詞的比較級和最高級有兩種形式，即：既可加-er/-est也可加more/mostc

11、ruel, strict, often, friendly, clever下列形容詞和副詞沒有比較級和最高（即表示“最高程度”或“絕對狀態(tài)”的形容詞和副詞沒有比較級和最高級）empty, wrong, perfect, unique, extreme, excellent, favourite, true, right, correct, extremely .形容詞副詞比較級最高級使用注意事項比較應在同類事物之間進行。誤：Your English is better than me.正：Your English is better than mine.比較級前可以有一個表示程度的狀語，最常見

12、的三大修飾詞是：a little, much, even。以下單詞也可用來修飾：any, far, still, a lot, yet, rather。My sister is a little taller than me.Their house is much larger than ours.另外，名詞短語也可修飾比較級，說明程度。Im three years older than he.特別提醒：very, quite, too不可修飾比較級。避免重復使用比較級。誤：He is more kinder to small animals than I.正：He is much kinde

13、r to small animals than I.誤：He is more cleverer than his brother.正：He is cleverer than his brother.比較要遵循前后一致的原則，注意前后呼應。The population of Shanghai is larger than that of Beijing.It is easier to make a plan than to carry it out.序數(shù)詞通常只修飾最高級。Africa is the second largest continent.The Yellow River is the

14、 second longest river in China.This is the third most popular song of Michael Jackson.形容詞副詞比較級最高級重點句型歸納句型一：形容詞或副詞比較級+than注意事項：該句型為比較級的最基本句型。只要看到than，即可確定前面使用比較級。He is taller than I am.The boy does his homework more carefully than the girl.句型二：less + 形容詞的原級 + than注意事項：該句型表示“不如、不及”，特別需要注意的是，less本身就是li

15、ttle的比較級，后面必須跟形容詞的原級，否定就造成了比較級的重復使用。This computer is less expensive than that one.句型三：as +形容詞或副詞的原級+ as注意事項：該句型表示對比的兩者程度相當，as之間必須跟形容詞或副詞的原級，決不能使用比較級。此外，還要確定使用形容詞還是副詞。確定的依據(jù)就是根據(jù)第一個as前的動詞，如果是系動詞（如be，感官動詞look, sound, smell, taste, feel等），那么就用形容詞的原級，如果前面的動詞是一般的實義動詞，那么就必須用副詞的原級修飾動詞。This lesson is as easy

16、as that one.Lucy talks with old people as politely as her sister.特別提醒：asas之間也可以跟名詞，句型如下：as +形容詞+ a/an +單數(shù)名詞+as He is as kind a person as his father. 他和他爸爸一樣都是善良的人。as + many/much+不可數(shù)名詞/可數(shù)名詞復數(shù)+as I can carry as much paper as you can. 你能搬多少紙，我也能。 I have as many books as you do. 我的書和你的一樣多。 Well give you

17、 as much help as we can. 我們將盡我們所能給你幫助。其它幾個關(guān)于asas的句型：as as one can：盡其所能 He began to run as fast as he could. as as possible：盡可能Please helpusas quickly as possible. as soon as一就 He will call me as soon as he comes here.句型四：not as/so +形容詞或副詞的原級+ as注意事項：該句型表示“前者不如后者”，往往可以與句型一和句型二替換。第一個as可以換為so。This clas

18、sroom is not as bright as yours.I cannot run as fast as you.句型五：the +形容詞或副詞最高級+ in / of / among +比較范圍注意事項：如果這里為副詞最高級，前面的the常常省略。介詞in和of的用法完全不一樣。in表示“在某一范圍內(nèi)”，如：in the classroom，in the world。of表示“在同類之間”，of后面的詞與主語同類，另名詞前一般有冠詞the。among表示“在（三者或三者以上）之間”，among后接代詞或沒有修飾語的名詞。The Changjiang River is the longe

19、st 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 + 形容詞最高級+可數(shù)名詞復數(shù)形式注意事項：one of有三大考點：1. 后跟形容詞最高級；2. 后接可數(shù)名詞復數(shù)形式；3. 作主語時主語為one，謂語動詞用單數(shù)形式。One of the smallest dinosaurs was about one metre long.句型七：比較級+and +比較級 / more and more +多音節(jié)詞

20、的原級注意事項：該句型表示“越來越”，如果該形容詞比較級構(gòu)成形式加er，則用前面的句型；如果該形容詞比較級加more構(gòu)成，則用后面的句型。It is getting hotter and hotter.The girl is becoming more and more beautiful.句型八：the +比較級+, the +比較級+注意事項：該句型意思為“越就越”，表示兩種情況同時變化。The more you eat, the fatter you will be.In the test, the more careful you are, the fewer mistakes you

21、 will make.句型九：be different from注意事項：該句型沒有運用比較級，但也是對兩者事物進行比較。注意前后比較需在同類事物中進行。My schoolbag is different from yours.句型十：the same as / the sameas注意事項：該句型同樣沒有運用比較級，表示兩者之間具有共同特性。注意這里的as和same為固定搭配，不能隨便變換。I dont want to buy the same things as Amy did. 句型十一：比較級+than + any other +名詞單數(shù)形式注意事項：any other 后面跟單數(shù)名詞

22、，表示“任何別的”，即主語在范圍內(nèi)，必須把自身從這一范圍內(nèi)除去，否則邏輯上不通。如果主語不在這一范圍內(nèi)，那么要把other去掉，只用any即可。Shanghai is larger than any other city in China. （上海在中國這個范圍內(nèi)，所以用any other）Shanghai is larger than any city in Jiangsu. （上海不在江蘇，所以只需用any）句型十二：比較級+than + the other +名詞復數(shù)形式注意事項：該句型相當于any other +名詞單數(shù)形式，常用來進行同義句改寫。該句型與句型十一雖然波表面上都是比較級

23、，但實際上相當于最高級。以下三句表達的是同一個意思。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.特別提醒：表示兩者(人或物)比較時，比較的對象應是同類事物，不同類的事物之間無法進行比較。形容詞比較級最高級練習題一、寫出下列形容詞和副詞的比較級形式。1. long_ 2.tidy_

37、hy he didnt go to school.打電話時用this介紹自己，用that詢問對方This is Mike speaking.Who is that speaking?That,those 常用在比較句型當中(as.as同級比較, .than 不同級別比較)The weather in Shenzhen is different from that in Beijing.The population of China is larger than that of Japan.The apples in this shop are much cheaper than those i

38、n that shop.There be句型一、專題講解1、定義： There be 結(jié)構(gòu)“某地有某人(某物)”。其基本句型為“There be + 某物或某人(主語) + 某地”。2、be動詞的選擇： There be 結(jié)構(gòu)中的謂語動詞be（is / are）在人稱和數(shù)上應與其后的主語保持一致。主語是不可數(shù)名詞或單數(shù)可數(shù)名詞時用is ；主語是復數(shù)時用are。3、具體結(jié)構(gòu)：(1) There is + 單數(shù)可數(shù)名詞/不可數(shù)名詞+ 地點狀語.E.g. There is a desk in the classroom. 在教室里有一張桌子。(2) There are + 復數(shù)名詞+ 地點狀語. E

39、.g. There are 5 apples in the box. 盒子里有五個蘋果?？谠E：“有” 字放前面，有“啥”放中間； 時間地點放后面；單數(shù)is, 復數(shù)are；注意be的兩變化。4、句型變化：(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. 樹下有一輛自行車There isnt a bike under the tree.E.g. There are 2 little girls in the room.在房間里有兩個小女孩。 There arent 2 little girls in the ro

40、om.(2)、一般疑問句及其答語：1、一般疑問句：把be動詞提前,首字母大寫,句末用問號即可。2、回答時，“用什么問，就用什么答”，用Is / Are there來提問，就用there is / are來回答?？隙ɑ卮穑篩es, there is / are. 否定回答：No, there isnt / arent.E.g. 1、There are two cats in the tree.樹上有兩只貓。Are there two cats in the tree? Yes, there are. No, there arent.2、There is a computer on the des

41、k . 在桌子上有一臺電腦。Is there a computer on the desk？ Yes, there is. No, there isnt.課堂練習：1. There is a new bed and an old desk in the room .否定句：一般疑問句 ：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問句）注意：There be句型在變成否定句或一般疑問句時，要注意把句中的some變成any。E.g.1、There is some water in the bott

42、le .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？（一般疑問句）2、There are some children in the picture. 圖片里有一些小孩。There arent any children in the picture. （否定句） Are there any children in the picture？（一般疑問句）課堂練習：1. - Are there _ shops near here? - No, there are _ shops

43、near here.A. some, not B. some, any C. any, not D. any, no2There are some tables on the floor.（變?yōu)榉穸ň洌?、就近原則：若句子中有幾個并列的主語時 be的形式要與離其最近的一個主語在人稱和數(shù)上保持一致。E.g. 1.There is a pen, two pencils and some books on the desk. 書桌上有一支鋼筆、兩支鉛筆和一些書。2.There are two pencils, a pen and some books on the desk. 書桌上有兩支鉛筆、一支

44、鋼筆和一些書。3.There some books，two pencils and a pen on the desk. 書桌上有一些書、兩支鉛筆和一支鋼筆。課堂練習：There milk and eggs on the table .在桌子上有牛奶和雞蛋。There eggs and milk on the table.7、“there be” 和“have”的區(qū)別There be表示“存在有” ；have（has）表示“所屬有”。他們都翻譯為“有”，但具體用法不相同，且兩種結(jié)構(gòu)不能同時合用。E.g.1、I have a book .我有一本書。（注：書歸我所有，我是書的主人。 所屬有）2、

45、There is a book on the desk .在桌子上有一本書。（書只是存在于桌子上，但書不屬于桌子所有。）8、常見的的介詞和介詞短語：介詞：at 在. in 在.里面 on 在.上面under 在.下面 behind 在.后面 near 在.附近介詞短語舉例：at home 在家 in the box 在盒子 on the floor 在地板上 in front of 在前面under the tree 在樹下 behind the door 在門后面 near the zoo 在動物園附近（2）變式練習一、用恰當?shù)腷e動詞填空。1.

54、enth eighth ninth tenth語法拓展：可數(shù)名詞&不可數(shù)名詞一、可數(shù)名詞與不可數(shù)名詞的區(qū)別普通名詞所表示的人或事物是可以按個數(shù)計算的，這類名詞叫可數(shù)名詞?？蓴?shù)名詞分為個體名詞（表示某類人或事物中的個體，如worker, farmer, desk, factory等）和集體名詞（表示作為一個整體來看的一群人或一些事物，如people,family 等）。如果普通名詞所表示的事物是不能按個數(shù)來計算的，這類名詞就叫不可數(shù)名詞。不可數(shù)名詞分為物質(zhì)名詞（表示無法分為個體的物質(zhì)，如meat, rice, water, milk, orange 等）和抽象名詞（表示動作、狀態(tài)、情況、品質(zhì)等抽

55、象概念，如work, homework, time, health, friendship等）。二、關(guān)于可數(shù)名詞可數(shù)名詞有單數(shù)和復數(shù)兩種形式。指一個人或一件事物時，用單數(shù)形式；指兩個或多個人或事物時用復數(shù)形式。名詞由單數(shù)形式變成復數(shù)形式的規(guī)則如下：1. 一般的名詞詞尾直接加-s 。如：book books room rooms house houses day days2. 以s, es, ch, sh, x 結(jié)尾的名詞，在詞尾加-es 。如：bus buses glass glasses watch watches dish dishes box boxes3. 以輔音字母+y結(jié)尾的名詞，要

56、先將y改為i再加-es。如：city cities body bodies factory factories等等。4. 以f 或fe 結(jié)尾的名詞，要將f或fe改為v再加-es。如：half halves leaf leaves knife knives wife wives5. 特例 悄悄話：特例常?？?，要記住。 child children man men woman women policeman policemen（規(guī)律：man men） tomato tomatoes potato potatoes NegroNegroes heroheroes初中英語以o 結(jié)尾的名詞變復數(shù)時只有這

57、兩個詞加-es，其余的加-s！如：photo photos foot feet tooth teeth悄悄話： oo變成ee。 sheep, Chinese, Japanese單、復數(shù)同形悄悄話：變復數(shù)時詞形不變。 people單數(shù)形式表示復數(shù)意義，要求謂語動詞用復數(shù)；people的復數(shù)形式peoples通常指“多個民族”。三、關(guān)于不可數(shù)名詞1. 不可數(shù)名詞沒有復數(shù)，當它作句子的主語時，謂語動詞要用單數(shù)形式。如：The food is very fresh.食品很新鮮。2. 有的不可數(shù)名詞也可以作可數(shù)名詞，有復數(shù)形式，但他們的意義往往發(fā)生變化。如：water （水） waters （水域） o
