  flood的可数性与及物性问题
  
  1. 用作名词，注意以下用法：
  (1) 若指一次洪水，为可数名词；若泛指一般意义的洪水，则为不可数名词。如：
  It was a serious flood. 那是一次严重的水灾。
  War, famine, and flood are terrible evils. 战争、饥荒、洪水都是可怕的灾难。
  但是，用作不可数名词时也可用复数形式，此时并不表示多次洪水。如：
  Floods in this area caused more than 500 deaths. 这个地区涨洪水造成了500多人的死亡。
  The heavy rain caused floods in the houses by the river. 这场大雨下得河边的房子都进了水。
  (2) 虽然本身表示“洪水”，但有时仍可用于water之前使用。如：
  The flood waters are going down. 洪水渐退。
  Flood water covered the fields by the river. 洪水淹没了
