比较级的含义及用法
比较级表示“更……”,常用于两者（人或事物）之间的比较，说明“前者比后者更……”,比较级前常用even, much, a little等修饰。
比较级的用法举例
Eg:Tom is tall. Jim is taller than Tom. （Jim比Tom 高。）
Jim is taller. 或Tom is shorter than Jim.(Tom比Jim 矮。)
Eg:Gina’s eyes are big.Mary’s eyes are bigger than Gina’s (eyes).
（Mary的眼睛比Gina大。）
Mary’s eyes are bigger.或Gina’s eyes are smaller than Mary’s.
(Gina的眼睛比Mary 小。)
总结：比较级的构成形式多为：主语+谓语+比较级+than+比较对象。
在上下文意思明确的情况下，也可以单独使用比较级。
Eg: This coat is too small. Do you have bigger one
