二、教学过程
(一)新课导学:
知识点讲解:
1.用形容词描述人或物时,可以放在名词前也可放在系动词后,
即:形容词+名词adj. + n. ;系动词+形容词 be + adj.
e.g. She has long hair. Her hair is long.
2.形容词比较级、最高级的构成
规则变化
(1)单音节词和少数双音节词
①一般情况在原级词尾加-er构成比较级,加-est构成最高级。
如:high→higher→highest。练习:tall_____ _____ short_____ _______
②以e结尾的词,直接加-r 或-st。如:large→larger→largest。
练习:late _____ ______ fine_____ ______ nice______ _______
③重读闭音节,末尾只有一个元音字母加一个辅音字母的词,先双写这一辅音字母再加-er或 -est。如:big→bigger→biggest。练习:fat _____ ______
hot______ ______ thin ______ _______ red______ ________
④以“辅音字母 + y”结尾的词,先变 “y”为 “i”,再加-er 或-est。如:happy→happier→happiest。
练: easy_____ ______ sunny______ _________ heavy________ ________
thirsty_______ _________ busy________ ______
(2)大部分双音节词和所有多音节词 在原级前加more构成比较级,加most构成最高级。如:dangerous→more dangerous→the most dangerous。
(3)不规则变化
有一些词的比较级、最高级变化是不规则的,需要特殊记忆。如:
good / well→better→best bad / ill→worse→worst
many / much→more→most little→less→least
far→farther→farthest(表示距离) / far→further→furthest (表示程度)
old→older / elder→oldest (表示新旧或年龄) / eldest (表示兄弟姐妹间的长幼关系)
①一些词的比较级和最高级,可以加-er或 -est,也可以加more或most,如:clever, polite等。
②一些词本身没有比较级和最高级形式,
如:right, wrong, full, empty, round, complete, wooden, dead, daily等。
3.形容词比较级的用法
(1)两者比较时用形容词比较级,其结构为“... 比较级 + than ...”。
如:Actions speak louder than words.
(2)在两者之间选择“哪一个更……”时,用句型 “Which / Who is +比较级, ... or ...?”。 如:Which sweater is cheaper, the red one or the yellow one?
(3)表示“两者之间最……的一个”时,用“the + 比较级”。
如:Lucy is the taller of the twins. 21世纪教育网
(4)表示“越……,越……”时,用“the + 比较级,the + 比较级”。
如:The more you eat, the fatter you will become.
(5)表示“越来越……”时,用“比较级 + and + 比较级”,多音节词和部分双音节词用“more and more + 形容词原级”。
如:We should make our country more and more beautiful.
(6)形容词比较级前可以用下列词修饰:much, a little, far, a bit, a few, a lot, even, still, rather等。如:It's much colder today than yesterday.
4.形容词最高级的用法
(1)三者或三者以上的人或物进行比较时,用形容词最高级形式。形容词最高级前通常需加定冠词the,句末常接in / of短语来表示范围。
如:He is the strongest of all the boys.
(2)表示“最……之一”时,用 “one of + the + 最高级”。
如:The light bulb is one of the most helpful inventions.
(3)形容词最高级前可以由物主代词、指示代词、名词所有格等修饰,此时不用定冠词the。如:Yesterday is her happiest day in her life.
