八上英语第六单元
形容词、副词比较级经典材料
初中英语中的比较用法
一、形容词、副词比的较级：
1、一般：加er、如：calmer、stronger、longer等
2、以e结尾的为了避免重复e;就直接加r;如nicer、finer
3、以辅音字母A 到Z 除掉A; E; I O; U; 一共21 个加y结尾的;把y改成i+er;如heavier、
4、以重读闭音节单个元音字母后面有辅字组r w y 除外且以辅字组big;top;stop结尾的;双写末尾辅音字母再加er;如bigger、thinner等
5、多音节和部分双音节的形容词、副词的比较级：前面加more;如：more interesting等
6、规则变化good/well---better;bad/ill---worse;much/many---more;little--less;far--farther/further 用法拓展：
一、Even甚至、a little、a bit ：略微;一点;much、a lot 、far等程度词+比较级
如：much stronger中much+stronger比较级；a little taller 比较级
a lot more fun ：fun的比较级为more fun 所以a lot +比较级
二、比较级的用法用than引出比较的对象
如he is more interested in PE than Chinese 中than 引出比较对象Chinese 语文
注意：有了than比就要跟比较的对象;且比较的对象之间要相一致
如：He has more books than Jim 对he 和Jim 是一致的：人与人比较;
His books are more than Jim 错因为His books 与Jim 不一致;故要改成Jim's books/Jim's
三：than引导比较时;有重复的成分;可以省略;不省略时用助动词代词
如：He has more books than Jim does这个does就是指代has;
因为重复出现;故省略;不省略时;应该用does
He is more ethletic than Jim is也是同理
四：than 后面可以加代词的宾格、也可以加代词的主格
He has more books than her宾格
He has more books than shedoes主格
五、无需引出比较对象时;就不用than;反之..有了than;就要有比较的对象
比较级的特别用法：
1、more and more;越来越........more指代形容词或副词的比较级;下同
2、the more;the more ：越......越........
3、less 、more都可跟部分双音节或多音节形容词或者副词构成比较级;两者意刚好义相反
4、the more of the two ：两者中更......的一个;
如the taller of the twin brothers 双胞胎兄弟中更高的一个
比较级易错题：
Who is good at PE;Tom or Jim good改成better看到or想到比较级
She is a little outgoing than me outgoing 改成more outgoing
This box is much heavy ..Heavy 改成heavier
John's homework is much more than Jim ..Jim 改成Jim's
看到a little、a lot、much、even、far想到比较级
He has much more homework than I do对
He has much more homework than me对
He has much more homework than me do错
than后可跟主格;省略助动词;如例句1中的do；也可以跟宾格;但是后面没有助动词
I have few books than you ..Few 改成fewer
He does much work than me..Much改成more
看到than;就用比较级
My hair is longer than her ..Her改成hers=her hair
比较的对象要一致;my hair 不能跟she 比较
注意：very、too 、quite、so、as....as只跟形容词、副词的原级;不跟比较级..
二、as ....as的形容词或者副词的原级比较;第一个as是副词;第二个as是连词;如：
1、He is as tall as Jim is
2、He is as good at PE as anyone elseis任何一个其它人
3、He has much money as she does
否定形式：not as ......as 或者not so ......As......或者never/seldom/hardly so/ as ....As
如He is not so/as tall as Jim is
He doesn't have so/as much money as she does
He never runs so/ as fast as Jim does
三、倍数的比较;经典例子：half an hou r;half倍数词为：半倍;an hour：名词
即：倍数词+名词：构成倍数的比较;
常见的倍数词用time可数；two times =double：双倍、两倍；half：半倍;一半
表示大小、尺寸的名词：size、width宽度、length长度、height高度;weight重量
This room is three times the size of that one ..这个房间的大小是那个房间的三倍..
The book is double=two timesthe weight of that one ..这书的重量是那本书的两倍..
拓展一、倍数词+as....as结构
This room is three times the size of that one ..这个房间的大小是那个房间的三倍..
=This room is three times as big as than that one..这个房间的大小是那个房间的三倍大.. The book is double=two timesthe weight of that one ..这书的重量是那本书的两倍..
=The book is double=two timesas heavy as that one ..这书的重量是那本书的两倍重..
拓展二、倍数词+比较级
This room is three times the size of that one ..这个房间的大小是那个房间的三倍..
=This room is three times bigger than that one ..这个房间比是那个房间大两倍..
