形容詞的比較級與最高級詳細(xì)講解(1)4頁

1、形容詞的比較級和最高級一、比較級的定義：大多數(shù)的形容詞都有三個級別：原級、比較級、最高級。其中比較級表示“更”，用于兩者之間的比較，用來說明“前者比后者更”，比較級前面一般用much, even, a little修飾，其中even, much 只能修飾比較級。二、比較級的構(gòu)成：（1）規(guī)則變化：單音節(jié)和部分雙音節(jié)的形容詞一般在詞尾加-er Eg: calm-calmer tall-taller smart-smarter以字母e結(jié)尾的直接在詞尾加-r Eg: nice-nicer fine-finer large-larger以“輔音+y 結(jié)尾的詞，變y為 i，再加-er” Eg: early

2、-earlier happy-happier busy-busier以重讀閉音節(jié)的單個輔音字母結(jié)尾的詞，雙寫輔音字母，再加-er Eg: big-bigger thin-thinner hot-hotter多音節(jié)或部分雙音節(jié)的形容詞在原級前面加more Eg: popular-more popular important-more important（2）不規(guī)則變化：少數(shù)形容詞的比較級變化是不規(guī)則的：good-better bad/ill-worse many/much-morelittle-less far-farther/further old-older/elder三、比較級的用法:(一

3、)當(dāng)兩個人或事物（A和B）進(jìn)行比較時，我們需要用到形容詞（副詞）的原級或者比較級1 表達(dá)“A和B一樣”，用asas的結(jié)構(gòu)。公式: A+be動詞+as+形容詞原級+as+B A+實義動詞+as+副詞原級+as+BEg I am as tall as you.我和你一樣高。 He runs as fast as I. 他跑得和我一樣快。2表達(dá)“A不如B”用not asas的結(jié)構(gòu)。公式: A+be動詞的否定形式+as+形容詞原級+as+B A+助詞的否定形式+動詞+as+形容詞原級+as+BEg I am not as tall as you.我沒有你高。 He doesnt run as fast

4、 as I. 他沒有我跑得快。2 表達(dá)“A大于B”用“比較級+than”的結(jié)構(gòu)。公式: A+be動詞+形容詞比較級+than+B A+實義動詞+副詞比較級+than+BEg I am taller than you.我比你高。 He runs faster than I. 他跑得比我快。(二)關(guān)于形容詞、副詞比較級的更多用法1比較級前面可以加上表示“優(yōu)劣程度”的詞或短語，意思是“更”，“得”。常見詞有much, a little, even, a lot, a great deal等。Eg He is much taller than I.他比我要高得多。 I jump a little hi

5、gher than he.我跳得比他高一點點。想一想，這些詞能修飾形容詞或副詞的原級嗎？2.比較級前面可以加上表示具體數(shù)量差別的結(jié)構(gòu),表示具體“大多少”，“小多少”，“長多少”，“短多少”等。Eg I am two years older than he.我比他大兩歲。This building is 20 meters higher than that one.3“比較級+and+比較級”表示“越來越”。 It is getting warmer and warmer天氣越來越暖和。He is running faster and faster他跑得越來越快。0ur country is b

6、ecoming more and more beautiful我們祖國越來越美了。4“the more， the more”表示“越，就越”，The more，the better.多多益善。The more careful you are,the fewer mistakes you will make.你越細(xì)心，犯錯就越少。5“the moreof the two”表示“兩個當(dāng)中較。的一個” The taller of the two boys is my brother.四、當(dāng)三個或三個以上的人或事物進(jìn)行比較時，我們需要用到形容詞（副詞）的最高級1表達(dá)“是中最的”,用“the+形容詞（副

7、詞）的最高級”的結(jié)構(gòu)。后面可以加上表示范圍的介詞短語或從句。公式：主語+be動詞+the +形容詞最高級+（名詞）+表示范圍的介詞短語或從句主語+實義動詞+（the） +形容詞最高級+表示范圍的介詞短語或從句Eg He is the tallest (student) in our class. He jumps the highest of the three boys. This is the best book that I have ever read.2表示“最的中一個”，用“one of +the +最高級+復(fù)數(shù)名詞”的結(jié)構(gòu)來表達(dá)。Eg He is one of the best

8、students in our class.他是我們班最好的學(xué)生之一。This is one of the most beautiful flowers in the garden.這是花園里最漂亮的花之。注意：(一) 形容詞的最高級前面有定冠詞the , 而副詞的最高級前面定冠詞the可以省略。但在形容詞最高級前有物主代詞時，不能要定冠詞the.（二）常見的用來表示范圍的介詞有in, of, among五、運用形容詞、副詞比較級應(yīng)當(dāng)注意的問題： (一)、按語法規(guī)則，than后面的人稱代詞應(yīng)當(dāng)用主格，但口語當(dāng)中有時會用賓格代替主格。 Eg He is more careful than I (

9、me).(二)、只有同類的事物才能比較 e.g Her bag is bigger than mine. 不能說 Her bag is bigger than I.The weather of Kunming is much better than that of Shenyang.不能說The weather of Kunming is much better than Shenyang.【語法專項練習(xí)題】1、That boy looks as as a boxer.A. strong B. stronger C. strongest D. more strong2、Then Summer
