explanation
Science to the human mind is what water is to the body
科学对于人类的思想就像水对于我们的身体一样
what = just as,意为“恰像,犹如,好比”用作连词,引导比较状语从句。(见新编高二英语上册p.21)
⑴ 惯用句式是:A is to B what C is to D. 意为“A对B而言正如C对D一样”例如:
Air is to us What water is to fish. 空气对于我们犹如水对于鱼。(介词to 表示两者的关系)
⑵ 也有“A is for B what C is for D.”句式。例如:
Poultry is for the cook what canvas is for the paint. 厨师离不了家禽正如画家离不开画布一样。(介词for表示“供…使用”)
⑶ what 引导的从句也可以放在句首,其句式是: What C is to D, that A is to B.(= A is to B what C is to D.)
在这一结构中,喻体在前,主体在后,相当于“just as...,so...”结构,意思也是“A对B而言正如C对D一样”例如:
What blood vessel is to a man’s body, that railway is to transportation.(=Just as blood vessel is to a man’s body ,so Railway is to transportation.)
铁路对于运输,好比血管对于人体一样。
呵呵,这下大家明白what的特殊用法了吧
