城里的孩子都熟悉这段经历：初次踏上地铁站台有多惊险，多刺激。我记得那时妈妈紧紧地握住我的手，要知道，那画满涂鸦的银色巨龙可是以玩命般的速度呼啸疾驰而至的。岂止厉害呀!
City kids know the deal; the excitement and danger of stepping onto a subway platform for the first time. I remember my mom holding my hand tight, with good reason, as this massive, screeching silver dragon （tattooed with graffiti） came hurdling around the comer at breakneck speed. It was beyond AWESOME!
