Question

改错air is to man is what water is to fish
这是个改错题。原句是air is to man water is to fish，然后老师让我们改，改完后是air is to man what water is to fish。再然后老师加了个“is”变成→“air is to man is what water is to fish”再让我们改。怎么改？
重点是加了个is后，怎么改？才是对的？不需要翻译。

Answer 1

what air is to man is what water is to fish
what引导air is to man，做全句主语
意思是：空气对人来说就好比水对鱼一样。
说说要求的具体改法，如加入成分或是去掉什么的。
去is吧：air to man is what water is to fish
