语法专项突破专题七 形容词和副词考点一 形容词、副语的句法功能不少学生对如何排列形容词的词序颇感困惑。
在此，我们向同学们介绍一个简易的记忆村子附近有一座漂亮的古代石桥。
I bought a cheap blue plastic pencil box yesterday.昨天我买了一个便宜的蓝色塑料铅笔盒。
They have got such a round brown wooden table.他们有一张褐色的木制圆桌。
考点三 形容词变副词的方法1．大多数形容词在词尾加ly。
careful —carefully ，quick —quickly ，bright —brightly2．以“辅音字母＋y”结尾的形容词，把y 变成i ，再加ly。
easy —easily ，happy —happily ，lucky —luckily3．以“元音字母＋e”结尾的形容词，去e 再加ly。
true —truly4．以le 结尾的形容词，去e 再加y。
terrible —terribly ，simple —simply ，possible —possibly考点四 形容词、副词的比较等级1．形容词和副词的比较级和最高级的概念和构成：英语中的形容词和副词常用三种形式来表达事物的等级差别，分别是原级、比较级和最高级。
大部分形容词和副词的比较级和最高级是在词尾加er/est或在词前加more/most，属于规则变化，但也有少数是不规则的变化。
先双写辅音字n is lesshe（1）比较级的特殊用法①比较级＋and＋比较级“越来越……”（“more＋原级”构成的比较级用more and more＋原级）China is becoming stronger and stronger.中国正变得越来越强大。
②the＋比较级．..，the＋比较级．..，“越……，就越……”The more we do for the people，the happier we'll be.我们为人民做得越多，我们就越幸福。
