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.
