英語比較級和最高級的用法
一、形容詞、副詞的比較級和最高級的構(gòu)成規(guī)則
1.一般單音節(jié)詞和少數(shù)以-er,-ow結(jié)尾的雙音節(jié)詞，比較級在后面加-er,最高級在后面加-est;
(1)單音節(jié)詞
如：small→smaller→smallest short→shorter→shortest
tall→taller→tallest great→greater→greatest
(2)雙音節(jié)詞
如：clever→cleverer→cleverest narrow→narrower→narrowest
2.以不發(fā)音e結(jié)尾的單音節(jié)詞，比較在原級后加-r,最高級在原級后加-st;
如：large→larger→largest nice→nicer→nicest able→abler→ablest
3.在重讀閉音節(jié)(即：輔音+元音+輔音)中，先雙寫末尾的輔音字母，比較級加-er,最高級加-est;
如：big→bigger→biggest hot→hotter→hottest fat→fatter→fattest
4.以“輔音字母+y”結(jié)尾的雙音節(jié)詞， 把y改為i,比較級加-er,最高級加-est;
如：easy→easier→easiest heavy→heavier→heaviest
busy→busier→busiest happy→happier→happiest
5.其他雙音節(jié)詞和多音節(jié)詞，比較級在前面加more,最高級在前面加most;
如：beautiful→more beautiful→most beautiful

easily→more easily→most easily
注意：(1)形容詞最高級前通常必須用定冠詞 the,副詞最高級前可不用。
例句： The Sahara is the biggest desert in the world.
(2) 形容詞most前面沒有the,不表示最高級的含義，只表示“非常”。
It is a most important problem.
=It is a very important problem.
6.有少數(shù)形容詞、副詞的比較級和最高級是不規(guī)則的，必須熟記。
如：good→better→best well→better→best
bad→worse→worst ill→worse→worst
old→older/elder→oldest/eldest
many/much→more→most little→less→least
far →further/farther→ furthest/farthest
二、形容詞、副詞的比較級和最高級的用法
1.“A + be +形容詞比較級 + than + B” 意思為“A比B更……”。
如：This tree is taller than that one. 這棵樹比那棵樹高。
注意：
�、� 在含有連詞than的比較級中，前后的比較對象必須是同一范疇，即同類事物之間的比較。
�、谠诒容^級前面使用much,表示程度程度“強得多”。
如：A watermelon is much bigger than an apple.

�、�. A is …times larger /higher/longer/wider than B.
如：Our school is twice bigger than yours.
我們學(xué)校比你們學(xué)校大兩倍。
6.形容詞、副詞的最高級形式主要用來表示三者或三者以上人或事物的比較，表示“最……”的意思。

7.修飾比較級和最高級的詞
1)可修飾比較級的詞
�、�.a bit, a little, rather, much, far, by far, many, a lot, lots, a great deal, any, still, even等。
�、�. 還可以用表示倍數(shù)的詞或度量名詞作修飾語。
�、�. 以上詞(除by far)外，必須置于比較級形容詞或副詞的前面。
注意： 使用最高級要注意將主語包括在比較范圍內(nèi)。
(錯) Tom is the tallest of his three brothers.
(對) Tom is the tallest of the three brothers.
2)下列詞可修飾最高級：by far, far, much, mostly, almost.

注意：

A. the happiest time B. a more happier time
C. much happiest time D. a much happier time

比較級和最高級的用法
1. 兩者相比(甲=乙)，用“as+原級+as”表示
Tom is as tall as Mike.
2. 兩者相比(甲〈 乙)，用“not as(so) +原級+as”或"less than"表示
I didn’t do my homework so(as) carefully as you.
The picture is less attractive than that one.
3. 兩者相比(甲〉乙)，用“比較級+than”表示
Our city is more beautiful than any other city in our country.
注意：1) 為了避免重復(fù)，在從句中常用one, that, those等詞來代替前面提過的名詞。
The weather here is warmer than that of Shanghai.
The radios made in our factory are better than those in your factory.
2) 比較等級應(yīng)注意避免和包括自己的對象比。
比較級+than+
any other + 單數(shù)名詞
all the other + 復(fù)數(shù)名詞
anyone else
any of the other + 復(fù)數(shù)名詞
3 )如果形容詞作定語修飾一個單數(shù)可數(shù)名詞，一般將不定冠詞a/an放在形容詞之后。
Our neighbour has _____ ours.
A. as a big house as
B. as big a house as
C. the same big house as
D. house the same big as
4 )比較級前一般不用冠詞，但若表示“兩者中較……時”。比較級前要加定冠詞。若比較級后有名詞，常在比較級前加不定冠詞，表示泛指。
E.g. 他是兩者中較高的一個
He is the taller of the two.
她唱得真動聽!我可從未聽過比這更好的嗓音了。
How beautifully she sings! I have never heard a better voice.
4. 三者或三者以上相比，表示最高級時，用“the +最高級”的結(jié)構(gòu)表示，這種句式一般常有表示比較范圍的介詞短語。
Zhang Hua is the tallest of the three.
He works (the) hardest in his class.
That was the least exciting football game I’ve ever watched.
This hotel is the most comfortable I’ve ever stayed.
注意：當(dāng)最高級的前面無限定詞the或有不定冠詞a/an時，僅表示“很……，非常……”
Monday is my busiest day.
星期一是我很忙的一天。
Qingdao is a most (very) beautiful coastal city.
青島是一個非常美麗的海濱城市。
