因为It's fun to do sth=To do sth is fun.
那么有没有It's fun doing sth呢?
另外,Eating food is good for your health能不能改为It's good for your health eating food.
答
不能.因为It's fun to do sth是固定搭配.To do sth is fun是动词不定式做主语的用法.
然后你改的句子也不对,要么改成It's good for your health to eat food.
也是固定搭配:It's good for sth /sb to do sth
你记住这些固定搭配就行了!
