保存按钮，为什么是块软盘？

The "save" icon looks like a floppy disk. 保存按钮的图标，长得像一块软盘。 Long ago, people saved files on floppy disks. 很久以前，大家把文件存在软盘里。 It was thin, and it could bend. 它薄薄的，还能弯一弯。 A floppy disk could only hold a little data. 它能装的东西，少得可怜。 People clicked it to keep their work safe. 点它一下，辛苦打的字才不会丢。 Today we use cloud storage instead. 现在我们都用云存储了。 But the old icon is still on every computer. 可这个旧图标，还留在每台电脑上。
