All the living things on Earth can't live without sunlight or water.用if改写
答

答
if there is no sunlight or water,All the living things on Earth can't live.
答
这句的翻译是“地球上所有的生物都不能离开阳光和水而存活”。这本来就是一个隐藏的虚拟语气，本来不会出现离开阳光和水的情况，是假的，用介词without代替了虚拟语气的动词表达。一旦用if来改写，说明有了从句，虚拟语气就要使用了。
If there were no sunlight or water, all the living things on earth could not live.
从句是对现在或者将来的虚拟表达式。
