The stoplight on the corner buzzes when it is safe to cross the street. I was crossing with a co-worker of mine, when she asked if I knew what the buzzer was for. I explained that it signals to blind people when the light is green. She responded, appalled, “What on earth are blind people doing driving?”
當行人可以安全穿馬路的時候,馬路拐角處的指示燈就會發(fā)出響聲。我正和一位同事一起過馬路,她問我知道不知道這響聲是干什么用的。我說,這是給盲人的綠燈信號。她膽戰(zhàn)心驚地問:“盲人究竟為什么要開車?”
