★形容詞的比較級和最高級：
形容詞有三種等級：原級、比較級、最高級。
3．原級：句中只有一者時用原級，其標(biāo)志詞是very, so, too, quite等。
e.g. His handwriting is very good.他的書法很好。 （一個人不作比較。）
太陽、月亮和地球那個大？
★ 形容詞比較級和最高級的構(gòu)成：
1.一般在原級后加er 構(gòu)成比較級，加est構(gòu)成最高級。
e.g. small smaller smallest
young younger youngest
2.以不發(fā)音的字母e 結(jié)尾的形容詞，直接加r 或st 構(gòu)成比較級和最高級。
e.g. nice nicer nicest
late later latest
3.以輔音字母+y 結(jié)尾的形容詞，變y為i ，再加er 或est, 構(gòu)成比較級和最高級。
e.g. busy busier busiest
heavy heavier heaviest
4.在重讀閉音節(jié)中，末尾只有一個輔音字母的形容詞，要先雙寫這個輔音字母，再加er或est， 構(gòu)成比較級和最高級。
e.g. hot hotter hottest
big bigger biggest
5.個別形容詞的比較級和最高級是不規(guī)則變化，需個別記憶。
e.g. good (well) better best
bad (badly, ill) worse worst
many(much) more most
little less least
far father farthest
或 further furthest
★ 副詞的比較級和最高級：
1.以ly 結(jié)尾的副詞，除early 變?yōu)?earlier 和 earliest 外， 其余一律在其前加more 和most。 如：carefully ? more carefully ? most carefully
2.規(guī)則變化直接加er 和 est 。 如：fast ? faster?fastest
3.個別詞是不規(guī)則變化，需要特別記憶。
如：well ? better ? best
far ? farther ? fastest
badly ? worse ? worst
4.句子中，副詞最高級前的the 可省略也可以不省略，但形容詞最高級前面的the 絕對不能去掉。
e.g. Who runs (the) fastest, Tom, Jim or Mike?
形容詞變副詞的規(guī)則：
1.一般情況下直接加“l(fā)y”，如quick---quickly 2.以“y”結(jié)尾的,先將“y”改成“i”,再加“l(fā)y”，如happy---happily
少數(shù)以e結(jié)尾的形容詞，要去掉e再加-ly。例如：true-truly等。
但絕大多數(shù)以e結(jié)尾的形容詞仍然直接加-ly。例如：polite-politely, wide-widely等。
形容詞變副詞通常是加ly,其變化有規(guī)律可循,請記住以下口訣：
一般直接加，“元e”去e加，“輔y”改i加，“l(fā)e”結(jié)尾e改y。
分別舉例如下：
quick?quickly,
true?truly,
happy?happily,
possible?possibly.
另外：
一、在形容詞詞尾直接加-ly。如:real-really; helpful-helpfully; careful-carefully; hopeful-hopefully; slow-slowly; quick-quickly; quiet-quietly
二、以輔音字母加y結(jié)尾的形容詞要變y為i,然后再加-ly。如:busy-busily; angry-angrily; easy-easily
三、某些以輔音字母加不發(fā)音的字母e結(jié)尾和以-ue結(jié)尾的形容詞要先去掉e,然后再加-y或-ly。如: terrible-terribly; true-truly; gentle-gently
另外,副詞還可以由形容詞加前綴a-得來,如:loud (adj.)-aloud (adv.)
此外,部分名詞加后綴也可變成副詞,如:part-partly。
例句: It is partly her fault. 有部分是她的錯。
需注意: friendly; motherly; lovely等詞是形容詞而非副詞。
再看轉(zhuǎn)化副詞。在英語中,有些詞既可以作形容詞,又可以作副詞,如early, much, fast, little, wide, loud等。 由于這類詞詞性雖不同,但詞形卻一樣,這就需要大家學(xué)會在特定語境中判斷它們各自的詞性。例句:Thank you very much. (adv.) 多謝。There is much water in the river. (adj.) 河里有很多水。The music is too loud. Please turn it down. (adj.) 音樂聲太大,請調(diào)低點。He speaks loud enough. So everyone in the room can hear what he said. (adv.) 他說話的聲音很大,所以房間里每個人都能聽到他的話。
另外,還有一類副詞和形容詞詞義相同,但拼寫卻不同,如well和good。例句He speaks good English. 他講一口流利的英語。He speaks English well. 他英語講得不錯。
多音節(jié)y結(jié)尾的詞 將y改為i后加ly easy-easily
happy-happily
heavy-heavily
單音節(jié)y結(jié)尾的詞 直接加ly gay-gayly (gaily)
sly-slyly (slily)
以ve結(jié)尾的詞 去e加ly true-truly
以le結(jié)尾的詞 去e加y gentle-gently
possible-possibly
其他以e結(jié)尾的詞 一律加ly nice-nicely
wise-wisely
polite-politely
以ll結(jié)尾的詞 只加y full-fully
以ic結(jié)尾的詞 加ally automatic-automatically
energetic-energetically
其他形容詞 均加ly careful-carefully
glad-gladly
形容詞的比較級專項
一、 變化規(guī)則；
1、 規(guī)則變化：（1）單音節(jié)詞和少數(shù)雙音節(jié)詞一般在詞尾加er或est：bright _____ ______; 以不發(fā)音的e字母結(jié)尾的加r,或st：large; 以輔音字母加y結(jié)尾的變y為I加er或est:easy； 以一個輔音字母結(jié)尾的重讀閉音節(jié)詞雙寫最后一個輔音字母再加er或est: big 以er，ow結(jié)尾的雙音節(jié)詞加er 或est:clever slow
（2）多音節(jié)詞前加more或most, 副詞最高級前省略the.
(3) 部分形容詞本身表示最高級，因此他們沒有比較級和最高級形式：favourite round
2、 不規(guī)則變化： good, well; bad, badly, ill; much, many; little; far; old;
注：只有少數(shù)形容詞和副詞有兩種比較級和最高級形式：clever old far
二、 形容詞各等級的用法：
1、 原級（同級）比較：as…as…; not as(so)…as…
We’ll give you as much help as we can.
She isn’t as(so)active in sports as before.
2. 比較級：表示兩者之間比…… 更……可用狀語much, a little, even等修飾： He made fewer mistakes than I did.
He is even richer than I.
3、 高級：形容詞最高級前必須加the, 副詞最高級前常省略the，后面多用of……， in……短語表示范圍：
It was the most/least interesting story I have ever listened.
He is the tallest of the three.
4、 如果在兩者之間表示“最……”時要在比較級前加the，而且還用of the two, of the pair短語：
John is the clever of the two boys.
Of the two boys, John is the clever.
三、 重點與難點：
1、 as…as…結(jié)構(gòu)：你和湯姆是一樣好的孩子。
You’re a boy as good as Tom.=You’re as good a boy as Tom.
2、 (1)too…to與 so…that sb.can’t…的句型轉(zhuǎn)換：前者為簡單句，主語只有一個，而后者為復(fù)合句，主語有兩個，試比較：
The man was too angry to be able to speak.
The man was so angry that he wasn’t able to speak.
The milk was too hot to drink.
The milk was so hot that we can’t drink it.
(2) too…to…與 not enough to句型的轉(zhuǎn)換：
He is too young to get married.=He is not old enough to get married.
The book is too difficult for me to read.=
The book is not easy enough for me to read.
3、 形容詞原級表示比較級含義：
約翰不象邁克那么苯。John is not so stupid as Mike.
John is less stupid than Mike.
John is cleverer than Mike.
4、 用比較級表示最高級：約翰是班里最高的男生。
John is taller than any other boy in the class.
John is the tallest boy in the class.
John is taller than :any other boy.
any of the other boy.
all the other boy.
any of the others.
any one else.
5、 the more….. the more….表示“越……越……”:
The more books you read, the wider your knowledge is.
The more food you eat, the fatter you are.
6、 more and more….表示“越來……越……”:
More and more students realized the importance of a foreign language.
Our country is getting stronger and stronger.
