半夜里我起来上厕所,看到儿子房间还亮着灯,我看到他正全神贯注地盯着电脑,手不停地按着鼠标。当时我觉得他看电脑的表情怪怪的,什么东西让他这么着迷了? When I got up to go to the bathroom in the middle of the night and saw my son’s room was lit up, I saw that he was concentrating on the computer with his hand on the mouse. At that time I think he looked at the computer’s expression weird, what made him so fascinated?
