小升初--形容词三个级别.doc

形容词三个级别

（一）形容词三个等级
1.原级，即用形容词原形，表示双方程度相同（具有某一相同特征）；
2.比较级，表示“较……”，“更……一些”的意思；
3.最高级，表示“最……”的意思。
PS:在英语里两个人或物体进行比较时要用比较级。三个人或三个物体(或三个以上的人和三个以上的物体)进行比较时要用最高级。

Examples
He is taller than me.他比我高。
His room is bigger than my room. 他的房间比我的房间大。
She is younger than my sister. 她比我妹妹年轻。
He is the tallest in our class.他在我们班最高。
Mike is the smartest student in our class.他是我们班最聪明的。
