To stay on track means to pay attention to your goal or purpose. But getting sidetracked is just the opposite. A train that is sidetracked gets sent to a different station or down a different line. Talking about train tracks, a rail is a single piece of steel that is part of the larger railway. Some rails are dangerous to touch. In some cities, a third rail provides power to a subway train, usually operating underground; electricity passes through the rail._________________________To stay on track意思是要关注你的目标或目的.但是偏离目标(getting sidetracked)正好相反.被转入入支线(sidetracked)的列车会被送到一个不同的车站或进入一条不同的线路.说起铁轨,轨道是单节的钢材,它是大型铁路的一部分.触摸一些轨道会很危险.在一些城市,第三道铁轨(电动机车的输电轨)给通常在地下运行的地铁列车供电,电力通过这道铁轨传输.__________________________
