引擎对于机器犹如心脏对于动物.
Engines are to machines_____________hearts are to animals.
答案是what,但我不懂这里是什么从句,而且为什么是用what,犹如的话应该用as啊
Engines are to machines_____________hearts are to animals.
答案是what,但我不懂这里是什么从句,而且为什么是用what,犹如的话应该用as啊
从结构上看,what分别做Engines are的表语和hearts are 的表语,同时,what应该理解成something as,也就是,原句可以理解为：
Engines are something to machines as hearts are (something) to animals.
Engines are something to machines as hearts are (something) to animals.
