来自《哈佛大学公共课-公正：该如何做是好第1集》

you're an onlooker.

只是一名旁观者
You're standing on a bridge overlooking a trolley car track.

你站在一座桥上俯瞰着电车轨道
And down the track comes a trolley car,

电车沿着轨道从远处驶来
at the end of the track are five workers,

轨道的尽头有五名工人
the brakes don't work,

电车刹车坏了
the trolley car is about to careen into the five and kill them.

这五名工人即将被撞死
And now, you're not the driver, you really feel helpless

但你不是电车司机你真的爱莫能助
until you notice standing next to you,

直到你发现在你旁边
leaning over the bridge

靠着桥站着的
is a very fat man.

是个超级大胖子
And you could give him a shove.

你可以选择推他一把
He would fall over the bridge onto the track

他就会摔下桥
