Thepromotional pack will be on sale for a limited period only.
这句的 only 为何放在句末? only 有如此的使用方法吗?
语法上将 only 划为焦点副词（使所修饰的词汇成为注意焦点的副词）。在一般情况下，only一直放在它所修饰的词汇之前，当only所修饰的词汇坐落于句末时，则也可以将only放在所修饰的词汇之后（即句末）。你的句子意思是：
The promotional pack will be on salefor a limited period only.=Thepromotional pack will be on sale onlyfor a limited period. 营销包仅在限时内折价销售。
