Even more serious difficulties include freezing weather conditions and heavy storms.
这句话中condition用了复数,但是练习题中condition答案给的单数,请问老师:怎么理解何时condition用单数,何时复数?
weather conditions 是正确的,而练习题中condition答案给的单数是错误的。如:
the worseening weather conditions 越来越糟糕的天气情况 (摘自《朗文当代高级英语辞典》第6版)
weather / atmospheric conditions 天气 / 大气情况 (摘自《韦氏高阶英汉双解词典》)
