是啊，对于上海这样的超大型城市来说，要解决交通问题，还是要靠地下和地面的轨道交通。前几年，我们盲目追求私家车，认为这样出行方便。可是事实证明无止境地增加私家车数量不论给交通还是环境都带来了严重的后果。

Yes, for a city as huge as Shanghai, to solve the traffic problem you need to rely on underground and aboveground light-rail transportation systems. These past few years, we blindly sought after private owned vehicles, because we felt they were convenient for travel. However the facts bear out that increasing the numbers of privately-owned vehicles to no end, heedless of traffic or the environment, has brought serious consequences.
