英语语法求助:这个句子里from修饰的是谁?
The transfer of heat and water vapor from the ocean to the air above it depends on a disequilibrium at the interface of the water and the air.
这句话里的from是修饰的heat and water这两样东西还是仅仅修饰water?为什么?
顺便也解释一下and并列的是transfer of heat 和water vapor，还是说heat和water vapor？（也就是说of后面heat和water vapor是不是作为一个整体接在of后面？）

答案

transfer of.from.to.
修饰的是heat and water vapor
因为只要在tranfer of 与 from之间的都被修饰（）
The transfer of heat and water vapor from the ocean to the air above it depends on a disequilibrium at the interface of the water and the air.
若这句话里的from是仅仅修饰water,则 （The transfer of heat ）主语一
and water vapor from the ocean to the air above 主语二
应当后接 depend
