专题09 形容词和副词比较等级易错点解题方法-2020年高考英语词汇语法易错点解题方法（上）

专题09 形容词和副词比较等级易错点解题方法 英语中的形容词和副词有三个等级，即原级、比较级和高最级。比较级主要用于两者比较，最高级主要用于多者比较。注意：不能使用双重比较等级。即构成比较级时不能既加词尾-er，又在其前加more；构成最高级时不能既在词尾加-est，又在其前加most，如不能说more better, most earliest 等。不过“比较级+and+比较级”这样的形式却完全可用。如：I am getting fatter and fatter. 我越来越胖了。  使用比较等级要注意合乎逻辑，高考常见考点及解题方法： 考点1：原级比较一般结构  as … as ; not as … as ; the same … as ; There are as good fish in the sea ___ ever came out of it.   A. than      B. like      C. as     D. so 【答案】: C. 【解析】：最佳答案C. as. 结构  as … as ; 意思是：.海里的好鱼是取之不尽的。 考点2：A is to B what / as X is Y ; 1.
