如果您只订购一件东西或者订购“x单位”的其他东西，那么更改模板使其说出“1单位”应该不是很困难。
It shouldn't be difficult to change the template to say "1 unit" if you ordered only one of something or "x units" otherwise.
使用这个模板定义的惟一问题是，Cheetah在单位中的一个单独行上打印s。
The only problem with this template definition is that Cheetah prints s on a separate line from unit.
注意：模板按原样使用 src 属性，而处理器根据需要将长度单位添加到 width 和 height 属性。
Notice that the template uses the src attribute as-is, and the processor adds the unit of measurement to the width and height attributes as needed.
