一个初一语法
首先看一下例句：
1、I often hear them sing songs in the next room.
2、I saw you put the key in your pocket.
3、I hear them singing songs in the next room.
4、I heard her singing in the classroom.
第一问（1和2):难道差了一个often,动词的时态就不一样吗?
第二问（3和4）：为什么两个动词的时态不一样?
often后真是原型吗？那不是有一句：She often goes to shchool by bike.

关于1 2 句：
对啊 often后面接动词原形,表示经常性的动作
关于3 4 句：
时态不一样是因为动作发生的时间不一样,中文翻译过来一个是
3 我听见他们正在隔壁唱歌
4 我那时候听见他们正在教室唱歌
也就是一个是现在正在发生的动作,一个是过去正在发生的动作.
