Tap water and ice自来水和冰块

Do not drink tap water. Use bottled water. This is what the UK FCDO and the US State Department tell visitors.

不要喝自来水，喝瓶装水。这是英国 FCDO 和美国国务院对旅客的说法。

Treat ice the same way if you do not know how it was made. Brush teeth with bottled water if you want to follow the same advice strictly.

不知道冰块怎么做的，按同样原则处理。想严格执行，刷牙也用瓶装水。
