人教版初二上英语第三单元课件--比较级.doc

【教师寄语：请你相信，态度决定高度！】比较级【基础知识】 一、比较级的意义：两个人或物之间的比较。表示“较”或“更一些”。标志词：than (比） 其基本结构：A + be动词 + 形容词比较级 + than + BHe is younger than me.他比我年轻。The cup is smaller than the desk.这个杯子比桌子小。My sister is elder than me.我姐姐比我大。二、形容词的比较级怎么构成？ 直接加er。如：darkdarker;talltaller; smallsmaller【即时训练】 strong_ small _ light_2. 以e结尾的形容词在词尾直接加-r构成。如：nicenicer【即时训练】 late_3. 重读闭音节双写末位字母再加er。 如：fatfatter 【即时训练】thin_run_4. 多音节形容词，在其前加more构成。 如： interestingmore interesting; 【即时训练】importantmore important。5.以辅音字母加y结尾的，把y变i，加er。earlyearlier【即时训练】 heavy_ easy _6.少数形容词的比较级是不规则的。原形比较级最高级good/wellbetterbestbad/illworseWorstmany/muchmoreMostlittlelessLeastfarfartherfurtherfarthestfurthestoldolderelderoldesteldest 三、重难点、考点。1、形容词/副词比较级前的修饰语. (1)much/a little/ a bit/ a lot / slightly. She is much taller than me. I am a little shorter than my mother. (2) 具体数量. My sister is ten years younger than me. (3) any/ no/ even/ some/ still Do you feel any better today? She is no older than mike.2、定冠词或指示形容词+比较级+名词表示比较。 The taller boy is John.3、不可使用双重比较级。错误My mother is more younger than my father.我妈妈比我爸爸小。正确My mother is younger than my father.4、与than搭配的词语形式。 （1）名词/代词 He is older than me.(2) 动名词/从句 Skiing is more exciting than skating. 5、asas中间用原级。 asas (与一样） not as(so)as （与不一样）6、表示倍数的词或其他程度副词做修饰语，放在as的前面。She can read twice as fast as you do.7、比较级与最高级可以转换，意思不变。如： She is taller than any other girl in Class5.=She is the tallest girl in Class5.8、比较的事物只能是同一级别的。如： My hair is longer than Marys. His shirt is more expensive than mine.9、如果比较对象相同，可用 thatthose代替第二个比较对象 。如： The weather in Shanghai is better than that in Wuhan. 10、比较级的特殊搭配。1）“比较级+and+比较级”表示“越来越”eg: He becomes fatter and fatter. 2）“The +比较级，the +比较级”表示 “越，越”The more ,the better.3）表示两者中”较“时，用the + 形容词比较级 + of 短语来表达。 He is the taller of the two.4）More than 不仅仅是，超过 ； Less than 不到5）more or less 差不多 The work is more or less finished.工作差不多完成了。【当堂练习】 一、写出下列形容词或副词的比较级。 old_ young_ tall_ long_ short_ strong_ big_ small_ fat_ thin_ heavy_ quiet_ nice_ good_ beautiful_ long_ fat_ slow_ far_ short_ good_二、根据句意填入单词的正确形式。1.Miss Chen is _ _than Mr. Wang.
