本来谈到短缺第一个想到的是 lack ,第二个才是shortage 然后查了一下词典
Shortage is synonymous with lack in designating a partial insufficiency, but more than lack it suggests an insufficiency of some established, required or accustomed amount：There was a shortage of bottled beer last week because of a delivery strike. Shortage also means the amount by which something is deficient: The total shortage amounted to $500.
