这东西形状奇特:是一个有洞的座位,还可能只是一个洞,只不过旁边带有搁脚板。它外表光滑,闪闪发亮,但又冷又硬。它通常为明亮的白色,尽管也有可能是用不锈钢制成的,或有着柔和的彩色外表。我们都见过它,我们都用过它。它令我们舒适,也给我们方便,是保持洁净的必需品,也是进步的象征。如果没有它,城镇生活就无法正常进行,旅行也会变得艰难。它可能是这个世界上我们见过的最大的“救生员”。 This thing is peculiarly shaped: a hole in the seat, it may be just a hole, but with a footrest next to it. It looks smooth, shiny, but cold and hard. It is usually bright white, although it may be made of stainless steel, or it has a soft, colorful appearance. We’ve all seen it before and we’ve used it. It makes us comfortable and convenient for us. It is a necessity to keep clean and a symbol of progress. Without it, urban life will not work properly and travel will get tougher. It may be the largest “lifeguard” we’ve ever seen in this world.
