第二章 詞 類,第五節(jié) 形容詞和副詞,知識(shí)梳理,一、形容詞 1.形容詞是主要用來(lái)修飾名詞的詞，表示人或事物的性質(zhì)、狀態(tài)、特征或程度好壞等。 2.形容詞可以直接修飾名詞，表示“的”。 如：a good student,a busy bee 3. 形容詞也可以放在句末。 如：That girl is smart.,二、副詞 1.副詞是用來(lái)修飾動(dòng)詞、形容詞或全句的詞，表示時(shí)間、地點(diǎn)、程度、方式等概念。 2.副詞表示動(dòng)作是“地”，一般放在動(dòng)詞之后。 如：The girls sing happily. Joe draws very well. 【注】在be，feel，smell，taste，get，become，sound，look，turn等連系動(dòng)詞之后，應(yīng)該用形容詞而不是副詞。 如：I feel sad when I see the film. It sounds good. You look terrible. Whats the matter? Leaves turn yellow in autumn. The food tastes delicious.,三、形容詞變副詞的規(guī)則 1.大部分形容詞在其詞尾直接加ly變成副詞。 如：realreally， quietquietly， helpfulhelpfully，slowslowly， carefulcarefully，quickquickly 【注】此類以ly 結(jié)尾的形容詞變比較級(jí)時(shí)，在前面加 more 2.以輔音字母加y結(jié)尾的形容詞要變y為i，然后再加ly變成副詞。 如： busybusily，easyeasily 3.某些以輔音字母加不發(fā)音的字母e結(jié)尾和以u(píng)e結(jié)尾的形容詞要先去掉e，然后再加y或ly變成副詞。 如： gentlegently ， truetruly,【注】(1)部分名詞加ly變成副詞。如： partpartly (部分地) (2)并不是所有以ly結(jié)尾的詞都是副詞，有的名詞加ly是形容詞。 如：friendfriendly(友好的)， mothermotherly(母親般的)， fatherfatherly(父親般的)， sistersisterly(姐妹般的)， brotherbrotherly(兄弟般的)， lovelovely(可愛(ài)的)，daydaily(每日的) (3)有些名詞加y變成形容詞。若名詞以重讀閉音節(jié)結(jié)尾且詞尾只有一個(gè)輔音字母，需雙寫(xiě)該輔音字母再加y。 如：rainrainy，snowsnowy，cloudcloudy，windwindy，fogfoggy，sunsunny，saltsalty，lucklucky，healthhealthy,四、形容詞和副詞的比較級(jí)和最高級(jí) 大多數(shù)形容詞和副詞都有等級(jí)的變化，表示“更”或“最”。 1. 形容詞和副詞的比較級(jí)和最高級(jí)的變化規(guī)則 (1) 規(guī)則變化,續(xù)表,(2) 不規(guī)則變化,【注】形容詞最高級(jí)前一般要加the。,2. 形容詞和副詞的比較級(jí)和最高級(jí)的用法 (1) 比較級(jí)常用于兩者之間的比較，一般結(jié)構(gòu)為：主語(yǔ)謂語(yǔ)形容詞或副詞的比較級(jí)than其他。同時(shí)，在比較級(jí)前可以用much，rather，a little，even等表示程度的副詞修飾。 如：She is taller than me. He runs faster than Tom. This house is much bigger than that one. Lily is a little thinner than Lucy. (2) 形容詞比較級(jí)and形容詞比較級(jí)，表示“越來(lái)越”。 如：It is getting hotter and hotter. (3) the形容詞比較級(jí)，the形容詞比較級(jí)，表示“越就越”。 如：The more， the better. 越多越好。,(4)最高級(jí)用于三者或三者以上的人或物的比較，表示人或物在某個(gè)范圍內(nèi)“最”。 如：Jack is the cleverest in the class. Shanghai is one of the biggest cities in China. 【注】(1)形容詞和副詞的原級(jí)可以用“as形容詞或副詞的原級(jí)as”結(jié)構(gòu)對(duì)兩者進(jìn)行比較，表示“和一樣”。其否定形式為“not as/so形容詞或副詞的原級(jí)as”，表示“不如/沒(méi)有”。 如：Lily is as old as Lucy. Tom is not as/so clever as Jim. (2)副詞的最高級(jí)前面的the 可以省略。 如：She is the best singer in our school.
