重難點(diǎn)知識(shí)講解(形容詞的比較級(jí)和最高級(jí))

1、重難點(diǎn)知識(shí)講解：形容詞的比較級(jí)和最高級(jí) 比較級(jí)的定義：大多數(shù)的形容詞都有三個(gè)級(jí)別：原級(jí)、比較級(jí)、最高級(jí)。其中比較級(jí)表示 更”，用于兩者之間的比較，用來(lái)說(shuō)明 前者比后者比較級(jí)前面一般用 much, even, a little 修飾，其中even, much 只能修飾 比較級(jí)。二、比較級(jí)的構(gòu)成：（1）規(guī)則變化：?jiǎn)我艄?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(jié)尾的直接在詞尾加-r:Eg: nice-ni cerfine-finerlarge-larger 以輔音+y結(jié)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(gè)輔音字母結(jié)尾的詞，雙寫(xiě)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(jí)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(jí)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(jí)的

3、用法：（一）當(dāng)兩個(gè)人或事物（A和B）進(jìn)行比較時(shí)，我們需要用到形容詞（副詞）的 原級(jí)或者比較級(jí)1表達(dá)“A口 B 一樣”，用asas的結(jié)構(gòu)。公式：A+be動(dòng)詞+as+形容詞原級(jí)+as+BA+實(shí)義動(dòng)詞+as+副詞原級(jí)+as+BEg I am as tall as you. 我和你一樣高。He doesn ' t run as fast as I.他沒(méi)有我跑得快。2. 表達(dá)“環(huán)如B”用not asas的結(jié)構(gòu)。公式：A+be動(dòng)詞的否定形式+as+形容詞原級(jí)+as+B A+助詞的否定形式+動(dòng)詞+as+形容詞原級(jí)+as+BEg I am not as tall as you. 我沒(méi)有你高。He ru

4、ns as fast as I. 他跑得和我一樣快。3表達(dá)“A大于B”用比較級(jí)+than ”的結(jié)構(gòu)。公式：A+be動(dòng)詞+形容詞比較級(jí)+than+BA+實(shí)義動(dòng)詞+副詞比較級(jí)+than+BEgI 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(jí)的更多用法1. 比較級(jí)前面可以加上表示 優(yōu)劣程度”的詞或短語(yǔ)，意思是更”, “得”。常見(jiàn)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(diǎn)點(diǎn)。想一想，這些詞能修飾形容詞或副詞的原級(jí)嗎？2. 比較級(jí)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(zhǎng)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(jí)+and+比較級(jí)”表示 越來(lái)越”。It is gett ing warmer and warmer .天氣越來(lái)越暖和。He is running faster and faster .他跑得越來(lái)越快。Our

6、 country is beco ming more and more beautiful.我們祖國(guó)越來(lái)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(cuò)就越少。5. “the more of the two表示兩個(gè)當(dāng)中較。的一個(gè)”The taller of the two boys is my brother.四. 當(dāng)三個(gè)或三個(gè)以上的人或事物進(jìn)行比較時(shí)，我們需要用到形容詞（副 詞）的最高

7、級(jí)1. 表達(dá)“是中最的”用“the形容詞（副詞）的最高級(jí)”的結(jié)構(gòu)。后面可 以加上表示范圍的介詞短語(yǔ)或從句。公式： 主語(yǔ)+be動(dòng)詞+the +形容詞最高級(jí)+ （名詞）+表示范圍的介詞短 語(yǔ)或從句主語(yǔ)+實(shí)義動(dòng)詞+ （the） +形容詞最高級(jí)+表示范圍的介詞短語(yǔ)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(gè)”用“one of +the +最高級(jí)+復(fù)數(shù)名詞”的結(jié)構(gòu)來(lái)表

8、達(dá)。Eg He is one of the best stude nts 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(jí)前面有定冠詞the ,而副詞的最高級(jí)前面定冠詞the 可以省略。但在形容詞最高級(jí)前有物主代詞時(shí)，不能要定冠詞the.（二）常見(jiàn)的用來(lái)表示范圍的介詞有in, of, amo ng五、運(yùn)用形容詞、副詞比較級(jí)應(yīng)當(dāng)注意的問(wèn)題：（一）、按語(yǔ)法規(guī)則，than后面的人稱代詞應(yīng)當(dāng)用主格，但口語(yǔ)當(dāng)中有時(shí)會(huì)用賓 格代替主格
