热水壶在英语中叫做"water kettle"，它的来源可能源自早期人们用水壶来煮沸水，以便做茶或咖啡。

例句：

Could you please boil some water in the water kettle for me? (请问你能在热水壶里给我煮些水吗？)

I prefer to make my tea with boiling water from a water kettle. (我更喜欢用热水壶里的沸水来泡茶。)

The water kettle is a convenient kitchen appliance for boiling water quickly. (热水壶是一种方便的厨房电器，可以快速煮沸水。)
