有些时候是可以互换的.但是个人觉得It is natual that能换成naturally的机会要大些natuarally换成 It is natual that的时候要注意语序和时态的变化：比如：Naturally,you were keyed up when you went on the platfo...Living in such a strange place, it is natural that I have no inclination to settle my heart here. 这句话中living....跟后面的形式主语it is natural that....是不是不搭配？这句话是不是语法有错误
