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.

在地铁或公共汽车上，一个身强力壮的男学生在冲向最后一个座位时，用胳膊肘把老妇人推到一边，这算不了什么，更不用说他本应站起来给她让座了。

Once the bike's seat tube forms a lock, the only way to steal the bike would be to cut through it, destroying it in the process.

一旦自行车车座杆形成一把锁，偷车的唯一办法就是把车切开，这样做的话自行车也就毁了。

I would tuck the rear wheel in a little closer and steepen the seat tube Angle, for compactness and to distribute a little weight to the feet.

我想抱膝的后轮在更接近和陡所在地管的角度，为紧凑和分配有点重量的脚。
