本周旅游提示。

去美国前，你应该查看你的电器所支持的电压范围。在中国，我们用的是220V，而美国用的是110V。所以在出发前，看看你的手机、照相机、平板电脑以及其他电器的电压范围是否在100V到240V之间。如果是，这些电器就可以在美国正常使用；如果不是，你就需要准备一个转换器，在一般超市都可以买到。

Before you go to the United States, you should check the wattage of your electrical appliances. In China, we use 220V, and in the United States they use 110V. So before you leave, see if you phone, camera, laptop and other electrical appliances have a range between 100V-240V. If they do, then you can use them in the US as you usually would: if not, you should prepare an adaptor, which you can find at a typical supermarket.
