人为什么会打嗝？

A hiccup is a sudden jump inside your chest. 打嗝，是你胸口里突然抽了一下。 It comes from the diaphragm under your lungs. 它来自肺下面那块叫横膈膜的肌肉。 Sometimes it tightens all by itself. 有时候，它会自己猛地一收缩。 Then your vocal cords snap shut, making a hic. 这时声带猛地关上，发出嗝的一声。 Eating too fast or cold drinks can cause it. 吃得太快、喝冰水，都可能引起打嗝。 Usually it stops by itself after a minute. 通常过一分钟，它自己就停了。 Holding your breath a little can help. 稍微憋一口气，能帮它快点停下来。
