比较级用法
形容词比较级用于两者(人或物)之间的比较,表示一方比另一方“更……”或“较……”,后面通常用比较连词than连接另一方所比较的人或物。than引导的是比较状语从句,但为了避免重复,从句中有些与主句相同的部分常常省略,而把相比较的部分省略出来。另外,在上下文明确时,形容词比较级也可以单独使用
例如:
This room is smaller than that one (is).
这个房间比那个房间小。
He is younger than I(am).
他年纪比我小。
His English is better than his brother 's (is). 他的英语比他哥哥的好。
