王 朋 Dec. 17th, 2013,2013年秋季學期大學英語4視頻答疑,比較級和同級比較,Page 2,一、形容詞與副詞比較等級的構成方法 二、比較等級的常見句型 三、比較等級的特殊句型 四、比較級和最高級的常見修飾語 五、形容詞與副詞的比較等級用法注意 六、比較等級的重要考點 七、比較級練習題 八、主謂一致練習題,講 課 提 綱,Page 3,1. 單音節(jié)和部分雙音節(jié)形容詞或副詞通常加后綴er和est構成比較級和最高級。此時，還需注意：若原級以字母e結尾，則只加-r和-st；若原級以“輔音字母+y”結尾，則應將y改為i，再加-er和-est構成比較級和最高級；若原級為重讀閉音節(jié)結尾，且末尾只有一個輔音字母，則雙寫這個輔音字母后再加詞尾-er和-est構成比較級和最高級。如： longlongerlongest largelargerlargest busybusierbusiest bigbiggerbiggest,一、形容詞與副詞比較等級的構成方法,Page 4,2. 多音節(jié)和部分雙音節(jié)形容詞在其前加more和most構成比較級和最高級。如： usefulmore usefulmost useful difficultmore difficultmost difficult 常見的不規(guī)則形容詞與副詞的比較等級變化： goodbetterbest； wellbetterbest； badworseworst； badlyworseworst； illworseworst； muchmoremost； manymoremost； littlelessleast； farfarther / furtherfarthest / furthest；等。 注：less和least也用來構成比較級或最高級，表示“較不”和“最不”：carefulless carefulleast careful。,一、形容詞與副詞比較等級的構成方法,Page 5,二、比較等級的常見句型,(1)兩者相比，甲=乙，用“as +形容詞或副詞原級+ as”。如： He got up as early as I did. 他和我起得一樣早。 注：當asas中間有名詞時，名詞要放在形容詞之后。如： I can carry as much paper as you can. 你能搬多少紙，我也能。 (2)兩者相比，甲乙，用“not as/so+形容詞或副詞原級+as”。 Corn doesnt need as/so much water as rice. 玉米不需要稻谷那么多水。,Page 6,二、比較等級的常見句型,(3)兩者相比，甲乙，用“比較級形容詞或副詞+ than”。如： You are taller than I. 你比我高。 He reads more careful than I. 他比我看書更認真。 (4)多者比較，用“the+最高級+比較范圍”。如： Tom is the tallest in his class. 湯姆是他班里個子最高。,Page 7,三、比較等級的特殊句型,(1) less/least +原級：表示降級的比較級或最高級。如： I am even less lucky. This is the least useful of the four books. (2) the+比較級, the+比較級：表示后者隨著前者的變化而變化，意為“越就越”，前者相當于一個條件句，因此，要用一般現(xiàn)在時代替一般將來時。如： The harder you work, the better result youll get. (3) the+比較級(+of the two)：表示“兩者中較的那個人或物”。如： Tom is the taller of the two brothers.,Page 8,三、比較等級的特殊句型,(4) 比較級+and+比較級：表示“越來越”， 單音節(jié)形容詞或副詞用“-er+and +-er”，warmer and warmer 多音節(jié)形容詞或副詞用“more and more” more and more beautiful (5) 比較級+than any other+單數名詞：表示最高級意義。 Mike is more intelligent than any other student in his class.(=Mike is the most intelligent in his class.) (6) 否定詞語+比較級：表示最高級含義。如： Nothing is easier than this.(=This is the easiest thing.),Page 9,三、比較等級的特殊句型,(7) 否定詞語+ soas：表示最高級含義。如： Nothing is so easy as this. (8) more+形容詞或副詞+than：表示對同一人或物在不同方面進行取舍，意為“與其說倒不如”，不論形容詞或副詞的長短，一律用morethan。如： He is more hungry than tired. (9) no +比較級+ than：表示對兩者的否定，意為“和一樣不”，與neithernor或“as+相反意義的形容詞或副詞+as”相當。如 Tom is no taller than Mike. =Neither Tom nor Mike is tall. =Tom is as short as Mike.湯姆和邁克都不高(或一樣矮)。 比較：“not+比較級前+than”表示前者不如后者。 Tom is not taller than Mike.湯姆不比邁克高。,Page 10,四、比較級和最高級的常見修飾語,1. 比較級的修飾語 表示“稍稍”、“一點”意義的a bit, a little, rather, some, any ； 表示“得多”的 much, far, a great / good deal, a lot； 表示“更加”意義的 still, even, yet ； 表示確定程度的修飾語，如分數或有關長度、時間、重量等名詞詞組通常放在比較級前，也可由 by 引出而置于比較級之后。 It is even colder than yesterday. He looks a bit happier now. He is two years younger than me. This bridge is longer than that one by 10 meters. 注：quite, very, so 等不可修飾比較級。,Page 11,四、比較級和最高級的常見修飾語,2. 最高級的修飾語 最高級前可用 the very, the second, (by) far the, nearly, almost, by no means 等修飾。 This is by far the most important. Hainan is Chinas second largest island. This is quite far the most expensive bicycle in the shop.,Page 12,五、形容詞與副詞的比較等級用法注意,1. 比較級的基本用法 形容詞和副詞有三個等級，即原級、比較級和最高級。比較級主要用于兩者比較，最高級主要用于多者比較。 2. 不能使用雙重比較等級 構成比較級時不能既加詞尾-er，又在其前加more；構成最高級時不能既在詞尾加-est，又在其前加most，如不能說more better, most earliest 等。不過“比較級+and+比較級”這樣的形式卻完全可用。如： I am getting fatter and fatter. Were going more and more slowly.,Page 13,五、形容詞與副詞的比較等級用法注意,3. 使用比較等級要注意合乎邏輯 請看兩組正誤句： 我的電腦比她的貴。 誤：My computer is more expensive than her 正：My computer is more expensive than hers. 上海人口比中國其他城市的人口要多。 誤：The population of Shanghai is larger than that of any city in China. 正：The population of Shanghai is larger than that of any other city in China.,Page 14,五、形容詞與副詞的比較等級用法注意,4. 比較級和最高級的常見修飾語 比較級的修飾語：常見的有far, even, still, a lot, a great deal, a bit, rather, three times, any, no等。如： She felt a great deal more comfortable now. 最高級的修飾語：常見的有by far, nearly, almost, not quite, second, next 等。如： I want to give my children the very best education I can afford. The Yellow River is the second longest river in China. 注：very不能修飾比較級，卻可修飾最高級，但它與一般的修飾最高的副詞有所不同，即它要放在最高級前定冠詞之后，而不是之前(另外，second, third, next等也要入在定冠詞之后)。,Page 15,六、比較級的重要考點,1、考查比較等級的基本用法 1) Of the two sisters, Betty is _ one, and she is also the one who loves to be quiet.
