形容词比较级 一 什么是形容词比较级 在英语中，形容词有原级、比较级和最高级三个等级。一般情况下在表示某人或某物的特征时用原级（即原形）；在表示两者（或两方面）之间的比较时要用形容词的比较级；在表示三者或三者以上的比较时要用形容词的最高级。 二 形容词比较级的构成 一般情况 加er small---smaller 以e结尾的形容词 加-r large--larger 以“辅音字母＋y结尾”的形容词 变y为i，再加-er easy--easier 末尾只有一个辅音字母，倒数第二个是元音字母的形容词 将这辅音字母双写再加-er hot—hotter thin—thinner 双音节和多音节形容词 用more 和 most 加在形容词前面 beautiful difficult 有少数形容词的比较级是不规则变化。 如：good—better, much—more 等。 三 形容词比较级的用法 1 在英语中，两者进行比较，强调“一方比另一方……”，可使用“形容词比较级 ＋ than”结构。比较级后面往往用连词than连接另一个比较的人或事物，但在上下文明确的情况下，形容词比较级可单独使用。 如： The ruler is longer than that one. 这把尺比那把尺更长。 This ruler is very long, but that one is longer. 这把尺子很长，那把尺子更长。 2. 形容词前有时还用much；a lot; a little; still; even等词修饰，但不能用very, so, too, quite等词修饰。 如：This box is much heavier than that one.这只箱子比那只箱子重得多。 四 形容词最高级的用法: 形容词最高级用于两个以上的人和物进行比较, 其结构形式为: 主语+谓语(系动词)+the+形容词最高级+名词+表示范围的短语或从句。 　She is??the best??student??in?? her class. 　她是班上最好的学生。? 　Shanghai is one of??thebiggest? cities??in??China. 上海是中国最大城市之一。 常用的不规则变化的形容词的比较级和最高级: 原级------比较级------最高级? good------better------best many------more------mostmuch------more------most bad------worse------worst far------farther, further------farthest, furthest 下面我们来做一点练习吧~ 1 ( )1.
