形容词、副词的比较等级

　　1.原级：表示A与B在某方面相同。

　　句型：1) A + 谓 + as + 原级 + as + B

　　 2) A + 谓(否定) + as/so + 原级 + as + B

　　 A与B在某方面不同

　　注意：not as / so... as = less than 不及；不如

　　eg. 1)This girl is as beautiful as that one.

　　 2)You don't eat so much as I

　　 3)This book isn't as interesting as that one

　　 = This book is ___ ________ _____ that one

　　2.比较级：两者进行比较（常与than连用）

　　1)I am cleverer than you 我比你聪明。

　　2)He runs faster than Jim 他比Jim跑得快。

　　3)I picked more apples than Jim.我比你摘的苹果多。

　　4)Which is more interesting, this one or that one? 哪本书更有趣，这本还是那本？

　　3.最高级：三者（或三者以上）进行比较（常与表范围的in , of短语连用）

　　( 注意：of + 个体名词单数 in + 集合名词 )

　　eg. 1)Shanghai is the biggest city in China.

　　 2)He runs fastest in our class.

　　 3)He is the tallest of the three boys.

　　 4)Which is the easiest, Lesson1, Lesson2 or Lesson3 ?

　　4.形、副比较等级的其他用法

　　 1) "比较级and 比较级" 表示 "越来越......"

　　eg. lazier and lazier 越来越懒

　　(但注意：如果多音节词用此结构时应为 more and more + 形、副)

　　eg. more and more beautiful 越来越漂亮

　　 2) "the比较级，the比较级" "越......，越......"

　　eg. the more, the better 多多益善

　　 _________ you are, _______ you will get.

　　 你越懒，收获越少。

　　 3) "the比较级of +二者" "二者中较......的一个"

　　eg. 1) Lucy is the younger of the twins.

　　 2) Of(A) the two books(B) this one(C) is thicker(D). _________

　　 4)表示二者相差多少用 "具体数量 + 比较级"

　　eg. He's a head taller than me.

　　 My brother is two years older than me

　　5)表示"是......几倍"时用"twice; three times等 + as...as"

　　eg. 1)This book costs twice as much as that one. 这本书的价钱是那本书的两倍。

　　 2)He has four times as many books as I have 他拥有的书是我拥有的四倍。

　　6)区别older / elder与farther / further

　　 older（年龄较老的）

　　 elder（指兄弟姐妹中排行在前的）

　　 farther (指距离"较远的")

　　 further(指抽象事物的"更进一步的")

　　eg.1)He went abroad for ________ studies.

　　 2)Fusun is _________ from our school than Zhaohua. 形、副比较等级还应注意

　　1.比较级前用a little ; much / a lot ; even / still来加强语气，表示"......一点儿；......得多 ； 更......"

　　eg. 1) a little bigger 大一点儿

　　 2)much more 多得多

　　 3)even heavier更重

　　但注意：不能在比较级前加so; too; very; quite等。

　　2.比较级必须是同类事物相比（即as; than后的词应与主语是同类事物），注意常用漏的代词有：that; those; one; ones

　　eg. 1)The apples (A) in this basket (B) are redder (C) than in that basket(D). _________

　　2)This knife (A) isn't (B) so (C) new as that (D). _______________

　　3)Our classroom (A) is (B) bigger (C) than Lily(D). _______________

　　3.个体与整体相比，不能包括个体，常用"any other + 单数名词"来进行比较。

　　eg.1）Betty(是个体) is cleverer than any student in her class(是整体). ( × )

　　正：Betty is cleverer than any other student in her class.

　　=Betty is cleverer than anybody else in her class.

　　=Betty is the cleverest in her class.

　　(特别注意以上三种句型的转换)

　　 2)China is bigger than any country in Africa.

　　 中国比非洲的任何一个国家都大。

　　 3) China is bigger than any other country in Asia. 中国比亚洲的任何一个其他国家大。

　　*4.使用最高级时应把主语包括在范围内。

　　eg. Mary is the tallest of all her sisters.( × )

　　(all her sisters已排除了Mary)

　　改：Mary is the tallest of all the sisters.

　　5.表示"第二、第三......"时，可在最高级前加"second , third, ..."（但"第一"不能用first）

　　eg. The Changjiang River is the first longest river in China. 改错：________________
