形容词比较级的用法形容词比较级通常可分为原级、比较级、最高级三种基本形式，具体而言，它们分别以下列形式出现在句中：它们分别以下列形式出现在句中：(1)as+原级+as(2)比较级+than(3)the+最高级+of (in)．．．需注意的原级的用法：(1)否定结构有A．．。
not as+形容词原级+as B及A．．．not so +形容词原级+as B两种结构。
(2)表示倍数有．．．times as+形容词原级+as的句型。
如：This garden is ten times as large as that one．This room is twice as large as that one．(3)half as+形容词原级+as表示“……的一半”。
如：This book is half as thick as that one．需注意的比较级的用法：(1)than后面接代词时，一般要用主格，但在口语中工也可换成me。
(2)比较级前还可以用much，even，still，a little来修饰。
(3)表示倍数时，试比较Our room is twice as large as theirs．我们的房间是他们的两倍那样大。
Our room is twice larger than theirs．我们的房间比他们的大两倍。
(4) I’ m two years older than you．我比你大两岁。
(5)“比较级+and+比较级”表示“越来越……”。
如: He becomes fatter and fatter．(6)"The+比较级…，the+比较级”表示“越……，越……”。
如：The busier he is，the happier he feels．他越忙就越高兴。
需注意的最高级的用法：(1)常见结构有：“of+复数意义的词”表示“在……之中的”，“在……中”；“in+范围、场所”表示“在……之中”。
如：He is the tallest“all the boys”．China is the greatest in the world．初中英语语法：比较级容易出现的问题一? 比较对象不明使用比较级时,前后两个比较项要保持一致?若前一个比较项是不可数名词,则后一个比较项可为替代词that?若前一个比较项是可数名词,则后一个比较项可为替代词one, ones 或those?此时,这些替代词是绝不可少的?例如:The books on this shelf are more interesting than the ones on that shelf.这个书架上的书比那个书架上的书有趣?These soldiers on top of the mountain can see further than those in the wood.山顶上这些士兵能比树林中的那些士兵看得远?另外还要注意,前后比较对象不能处于同一范围内?例如:Li Ming is cleverer than any other student in his class. 李明在他班里比任何学生都聪明?句中的other 不可少,因为any student 也包括李明在内?依照常理,在同一时期或同一个方面,人或物自身不能与自身相比较?在any 之后加上other,就是要从any student 中排除李明本人?如果二者不是在同一范围内,后一个比较对象就可为“any + 单数名词”?例如:Shanghai is larger than any city in Africa.上海比非洲任何一个城市都大?二? 误用修饰语如果句意上需要,比较级前面可以有much, no, rather, far, a little, a lot, even, still等修饰语?例如:Be united as one, and you’ll win still great er victory.团结起来,争取更大的胜利?Canada is much larg er than Mexico.加拿大的面积比墨西哥大得多?三? 词序有误在安排比较结构中的词序时,有些学生只考虑中文意思,却忽略了英语的习惯表达方式?例如:1. 他比我高一头?误:He is taller a head than I.正:He is a head taller than I.2. 这个房间是那个房间的两倍大?误：his room is as twice large as that one.正：his room is twice as large as that one.3. 汤姆似乎不像吉姆那样是个好孩子?误T om doesn’t seem to be as a good boy as Jim.正T om doesn’t seem to be as good a boy as Jim.4. 她工作越努力,取得的进步就越大?误he harder she worked, the more she made progress. 正:The harder she worked, the more progress she made.四? 随意省略the?形容词最高级前面要加定冠词the,而形容词的比较级前边通常不加定冠词the?如果两者进行比较,形容词比较级后面没有than,而用of 短语来明确说出两个比较的对象时,形容词比较级前面必须加定冠词the?例如:莉莉是双胞胎中较高的那个?误: Lily is taller of the twins.正: Lily is the taller of the twins.1. 表示两者之中“较...”，用the+比较级+of the two。
I'll give you the bigger of the two steaks; I'm not very hungry.我要把这块比较大的牛排给你，我不怎么饿。
2. 定冠词或指示形容词+比较级+名词表示比较。
The taller man is the boss of the restaurant and the shorter one is his brother.那个身材较高的男人是餐馆老板。
较矮的那位是他弟弟。
3. 有少数以-ior结尾的属于拉丁语的形容词，如inferior(次于), junior(年幼的;下级的), posterior(之后), prior(之前), senior(年长的,上级的), superior(优于)等本身就有比较的意思，后面不接than，常与介系词to连用，后面用宾格。
I am two years junior to you.我比你小两岁。
该句相当于?I am two years your junior.I am your junior by two years.I am two years younger than you (are).类似结构还有?be senior to(年长于)+宾格?be older than+主格be superior to(优于)+宾格?be better than+主格be inferior to(劣于)+宾格?be worse than+主格4. 比较形容词可以被修饰语如a little(一点), much(得多), even(更加), still(更加), far(...得多), very much, any, no, rather, a lot (a great deal), a little (a bit)等修饰，但不可用very修饰，表示某种程度。
The sun is a lot bigger and brighter than the moon.太阳比月亮大得多、亮得多。
