The man would laugh really ----and then he would pat me on top of the head.

问题描述:

The man would laugh really ----and then he would pat me on top of the head.
A differently B hard C less D untruly
please tell me why

laugh really ---
首先,得选一个副词,修饰动词laugh,所以C排除
其次,得使句子有意义,A differently (不同) D untruly(不真实)一般都不形容笑,所以只能是B hard .
那人笑的太厉害了,然后才拍拍我的头顶.
