[单项选择]Manners nowadays in metropolitan cities like London are practically non-existent. It is nothing for a big, strong schoolboy to elbow an elderly woman aside in the dash for the last remaining seat on the tube or bus, much less stand up and offer his seat to her, as he ought to. In fact, it is saddening to note that if a man does offer his seat to an older woman, it is nearly a Continental man or one from the older generation.

Are we really so lost to all ideals of unselfishness t
