新概念英语第三册问题——第十课,第一段最后一句for she went down on her first voyage with heavy loss of life 和第二段最后一句as there were not enough lifeboats for everybody,1500 lives were lost.
为什么life一个是复数一个是单数.

优质解答

with heavy loss of life -------- 这里的life泛指“人命,生命”,是不可数名词
1500 lives ------ 这里的lives指的是people's lives,1500 lives----一千五百条人命.是可数名词.
