形容词、副词比较级和最高级
语法精讲
1.句型: as+形容词/副词原级+ as“和......一样”
2.句型: not as/so+ 形容词/副词原级+as“不如”
not as (so)...as=形容词/副词反义词的比较级+ than
3.表示倍数:倍数+as+形容词/副词原级+as
形容词和副词的比较等级是中考的必考点。而在词形转换题型中，则需先判断用原级还是比较等级。
1.原级的判定方法
1）由表示程度的副词very， so， too， enough， quite等修饰时，用形容词原级。
The film is too boring. 这部电影太无聊了。
2）A+be+as+原级+as+B，意为“A与B一样……”，表示相同或相等。
My best friend is as tall as her mother. 我最好的朋友和她妈妈一样高。
3）A+be+not+so/as+原级+as+B，意为“A不及B那样……”，表示不如或不相等。
This red skirt is not so beautiful as that blue one. 这条红色的短裙不如那条蓝色的漂亮。
4）A+be+倍数+as+形容词原级+as+B，表示“A是B的……倍”（常见倍数：一半half，一倍once，两倍twice，三倍及以上：数字+times）。
Our school is twice as large as theirs. 我们学校是他们学校的两倍大。
5）as much/many...+as，表示前后的数量相同。
John earns as much money as his brother.约翰挣的钱和他的哥哥一样多。
6）as+原级+as+用作比喻的名词，意为“像……一样”，此结构可形成许多习惯用语，多用于口语。
He is as busy as a bee.他像蜜蜂一样忙碌。
2.比较级的判定方法
1）由表示程度的副词a little, a bit, a few, a lot, much, even, still, far, rather, any等修饰时，用形容词或副词的比较级。
It is even colder today. 今天甚至更冷了。
2）“the+比较级...，the+比较级...”表示“越……，就越……”。
The more fruit you eat, the healthier you are. 你吃的水果越多，你就越健康。
3）“比较级+and+比较级”，表示“越来越……”。
注意：若比较级是在原级前加more构成的，则用“more and more+原级”表示“越来越……”。
Our city is becoming more and more beautiful. 我们的城市变得越来越漂亮了。
4）表示两者进行比较时用比较级，其结构为A+be+比较级+than+B表示“A比B……，”即A>B。（注意比较的对象要一致）如果加入数字，则表示确切的量的关系。
My bike is more beautiful than hers. 我的自行车比她的（自行车）漂亮。
比较级的常见结构有：
1.A+be+less+多音节形容词原级+than+B，表示“A不及B……”。
The film was less funny than the book.这部电影没有这本书有趣。
2.表示两者之间进行选择时，用句型：Which/Who+be+比较级，A or B 。
Which is nearer to the sun, the moon or the earth 哪个离太阳更近，月亮还是地球？
3.表示两者之间较……的一个（of the two）时，常用the+比较级结构。
He is the thinner of the two.他是两个中较瘦的那个。
4.表示几倍于……时，用倍数+比较级+than表示。
The Yangtze River is almost twice longer than the Pearl River.长江大概比珠江长两倍。
3.最高级的判定方法
1）表示三者或三者以上的人或物进行比较时，用最高级形式。形容词最高级前必须加定冠词the，副词最高级前可以不用。句末常跟一个in/of/among 短语来表示范围。即用“A+be+the+最高级（in/of/among）...” 表示。
This picture is the best of all. 这幅画是所有的画中最好的。
2）表示“A是……中最……之一”时，用“A+be+one of+the +形容词最高级+名词复数形式”
Deng Ziqi is one of the most popular singers.邓紫棋是最受欢迎的歌手之一。
3）表示在三者或三者以上的人或物中进行选择时，用句型：Which/Who be the +最高级，A， B or C
Who is the tallest, Tom, Kate or Bill 汤姆、凯特、比尔，谁最高？
