重難點知識講解(形容詞的比較級和最高級)

1、重難點知識講解：形容詞的比較級和最高級 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-calmertall-tallersmart-smarter 以字母e結尾的直接在詞尾加-r:Eg: nice-ni cerfine-finerlarge-larger 以輔音+y結尾的詞，變y為i，再加-er ”Eg: ea

2、rly-earlier happy-happier busy-busier 以重讀閉音節(jié)的單個輔音字母結尾的詞，雙寫輔音字母，再加-er :Eg: big-biggerthin-thinnerhot-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 popularimportant-more importa nt（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：（3）good-betterbad/ill-worsemany/much-morelittle-lessfar-farther/further old-older/elder三、比較級的

3、用法：（一）當兩個人或事物（A和B）進行比較時，我們需要用到形容詞（副詞）的 原級或者比較級1表達“A口 B 一樣”，用asas的結構。公式：A+be動詞+as+形容詞原級+as+BA+實義動詞+as+副詞原級+as+BEg I am as tall as you. 我和你一樣高。He doesn ' t run as fast as I.他沒有我跑得快。2. 表達“環(huán)如B”用not asas的結構。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 ru

4、ns as fast as I. 他跑得和我一樣快。3表達“A大于B”用比較級+than ”的結構。公式：A+be動詞+形容詞比較級+than+BA+實義動詞+副詞比較級+than+BEgI am taller than you. 我比你高。He runs faster than I. 他跑得比我快。（二）關于形容詞、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

5、 little higher 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)量差別的結構，表示具體 大多少” 小多少”長多少”短多少”等。Eg I am two years older tha n 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 gett ing warmer and warmer .天氣越來越暖和。He is running faster and faster .他跑得越來越快。Our

6、 country is beco ming 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. 你越細心，犯錯就越少。5. “the more of the two表示兩個當中較。的一個”The taller of the two boys is my brother.四. 當三個或三個以上的人或事物進行比較時，我們需要用到形容詞（副 詞）的最高

7、級1. 表達“是中最的”用“the形容詞（副詞）的最高級”的結構。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EgHe is the tallest （stude nt） 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+復數(shù)名詞”的結構來表

8、達。Eg He is one of the best stude nts in our class. 他是我們班最好的學生之一。 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, amo ng五、運用形容詞、副詞比較級應當注意的問題：（一）、按語法規(guī)則，than后面的人稱代詞應當用主格，但口語當中有時會用賓 格代替主格
