        教學(xué)步驟:

        一.學(xué)生看教材P.119 ,并完成下列小結(jié)

        (一)形容詞比較等級(jí)的含義 :形容詞有________,_________,_________,三個(gè)比較等級(jí)。

        1. 原級(jí)(原形)如:他的頭發(fā)很長。His hair is very ___________.

        2. 比較級(jí):表示“較…” 或“更…些”。

        如:我的頭發(fā)比他的長。My hair is ________ ________his.

        健康比財(cái)富更重要。Health is __________ _________than wealth.

        3. 最高級(jí):表示“最…”

        如: 快樂是最好的藥。Happiness is the ____________ medicine.

        ( 二).形容詞比較級(jí)、最高級(jí)的構(gòu)成規(guī)則

        單音節(jié)詞和部分雙音節(jié)詞的構(gòu)成方法:

        1.一般在詞尾加_________或_______,

        如:small---smaller---smallest, long---_________--__________

        2.以字母_____結(jié)尾的詞加____或______,

        如:large-larger---largest, nice---__________ -____________

        3.以重讀閉音節(jié)結(jié)尾并且末尾只有一個(gè)輔音字母的應(yīng)先__________,再加________ 或__________.

        如;big----_______--__________; fat-________-__________

        4. 以輔音字母 + y結(jié)尾的,先變y為___,再加___或______.

        如:heavy---___________-__________

        多音節(jié)詞和部分雙音節(jié)詞的構(gòu)成方法:

        在原級(jí)前加______________ 或 __________________,

        如popular,-more popular-most popular

        Interesting-______________ -__________________

        特殊的:good/well---- better best bad/ill --- worse worst

        Manny/much--- more most little ---- less least

        far---- farther/further 或 further/furthest

        old – older/elder---oldest/eldest

        (三). 形容詞比較級(jí)、最高級(jí)的用法

        1.學(xué)生小結(jié)

        2.教師點(diǎn)撥

        比較級(jí):A +比較級(jí) + than + B (A.B不能相互包括;A比B在某方面程度更高)

        如:貓比其他動(dòng)物更可愛。 Cats are more lovely than other animals.

        最高級(jí):A +the +最高級(jí) +in/of(A在某方面程度最高 ,)

        注:A應(yīng)在那個(gè)范圍內(nèi)程度最高

        誤:Tom is the tallest of all his classmates.

        ※同級(jí)比較: A=B A + as + 原級(jí) + as + B 表示A.B在某方面程度一樣。

        如:圣誕樹幾乎和房間一樣高

        The Christmas tree is as tall as the room.

        A不如 B A not as/so+原級(jí)+as + B 表示A在某方面不及B,此類句型可以改為比較級(jí)形式。

        如:他沒有我高。He is not as (so) tall as I/me.

        =He is shorter than I/me.

        這個(gè)男孩不如那個(gè)男孩細(xì)心。

        This boy is not as careful as that boy.

        =This boy is less careful than that one.

        =That boy is__________________________.

        二.比較結(jié)構(gòu)中應(yīng)注意的七個(gè)方面見教材P.120

        1.比較級(jí)與最高級(jí)可以轉(zhuǎn)化

        如:在中國,長江比其他任何河流都長。

        The Yangtze River is _______than any other river in China.

        = The Yangtze River is _____ ________ river in China.

        2.當(dāng)某一事物與其他事物作比較時(shí),被比較事物中不能包括本身。

        Eg1.他比班上其他學(xué)生高。

        He is _______ than any ________student in his class.

        Eg2.上海比湖北任何一個(gè)城市都大。

        Shanghai is __________ than ________ ________ city in Hubei.

        3.如果比較對象相同,可用 that/those 代替第二個(gè)對象。

        Eg1:重慶的天氣比上海的天氣要好。

        The weather in Chongqing is better than that in Shanghai.

        Eg2:第二冊的課文比第三冊的容易得多。

        The texts in Book2 is much easier than ________in Book3.

        4.兩個(gè)比較級(jí)用and 連接,表示“越來越…”

        (e.g) bigger and bigger 越來越大

        more and more beautiful 越來越美

        5.the + 比較級(jí),the + 比較級(jí),表示“越….越…..”

        越多越好。The more ,the better.

        你練得越多,做起來就變得越容易。The more you practice , the easier it becomes.

        6.表示“兩者較…..”時(shí),用 “the + 形容詞比較級(jí) + of 短語”來表達(dá)

        他是兩人中較高者。He is the taller of the two.

        7、形容詞的比較級(jí)可以用much , a little , a lot ,even ,three years, third, twice等修飾,使原來的比較級(jí)在語意上更加明確,

        vv如: 雞要比奶牛小得多。Chickens are much smaller than cows.

        我比你大點(diǎn)。I am a little older than you.

        8..one of + 最高級(jí)+單數(shù)名詞 表示“最…之一”

        One of the most famous rock bands

        9..序數(shù)詞+最高級(jí)+單數(shù)名詞 表示“第幾…”

        如:我是班上第三高的男生。I’m the third tallest boy in our class.

        10..最高級(jí)前面要加 the ,但最高級(jí)前有指示代詞,物主代詞或名詞所有格修飾時(shí),其前不能再加the

        (e.g) 這是我最好的一本書。This is my best book.

        鞏固提高

        一.寫出下列形容詞的比較級(jí)和最高級(jí)
