Dear Sir or Madam,

尊敬的先生或女士：

I bought an electronic dictionary from your online store on January 1st,but I found it has some problems after using it for a short period of time.

1月1日我在贵网店购买了一部电子词典，但在使用了一段时间以后，我发现它有一些问题。

To begin with, the battery needs recharging after a mere 2 hours of use.

首先，在仅仅使用两小时后，电池就需要充电。

This means that I need to carry my charger with me when I go out for a day.

这就意味着当我出门一天时，就需要随身携带充电器。

In addition, the buttons on the electronic dictionary are so small that it is nearly impossible to type anything with them.

此外，这部电子词典的按键如此之小，以至于几乎无法通过键盘输入任何东西。

Personally, I find this to be completely unacceptable.

对我个人而言，我认为这一点完全不能接受。

Therefore, I would like either to change for another model that works well or a full refund.

因此，我希望要么为我换一个能正常运行的型号，要么全额退款。

Your help is greatly appreciated.

非常感谢您的帮助。

Yours sincerely, Zhang Wei

您真诚的，张伟
