          教學步驟:

          一.學生看教材P.119 ,并完成下列小結

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

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

          2. 比較級:表示“較…” 或“更…些”。

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

          健康比財富更重要。Health is __________ _________than wealth.

          3. 最高級:表示“最…”

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

          ( 二).形容詞比較級、最高級的構成規(guī)則

          單音節(jié)詞和部分雙音節(jié)詞的構成方法:

          1.一般在詞尾加_________或_______,

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

          2.以字母_____結尾的詞加____或______,

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

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

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

          4. 以輔音字母 + y結尾的,先變y為___,再加___或______.

          如:heavy---___________-__________

          多音節(jié)詞和部分雙音節(jié)詞的構成方法:

          在原級前加______________ 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、最高級的用法

          1.學生小結

          2.教師點撥

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

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

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

          注:A應在那個范圍內程度最高

          誤:Tom is the tallest of all his classmates.

          ※同級比較: A=B A + as + 原級 + 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+as + B 表示A在某方面不及B,此類句型可以改為比較級形式。

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

          =He is shorter than I/me.

          這個男孩不如那個男孩細心。

          This boy is not as careful as that boy.

          =This boy is less careful than that one.

          =That boy is__________________________.

          二.比較結構中應注意的七個方面見教材P.120

          1.比較級與最高級可以轉化

          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.當某一事物與其他事物作比較時,被比較事物中不能包括本身。

          Eg1.他比班上其他學生高。

          He is _______ than any ________student in his class.

          Eg2.上海比湖北任何一個城市都大。

          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.

          4.兩個比較級用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,the + 比較級,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,用 “the + 形容詞比較級 + of 短語”來表達

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

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

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

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

          8..one of + 最高級+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+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..最高級前面要加 the ,但最高級前有指示代詞,物主代詞或名詞所有格修飾時,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和最高級
