    It's(well)worth doing…
    It's(well)worth one's while doing/to do…
    It's(well)worth while doing/ to do

    2.作形式主语替代主语从句
    1. It is clear ( obvious,true,possible,certain....) that.....
    该句型中it 是形式主语,真正的主语是that 引导的主语从句,常译为"清楚(显然,真的,肯定...)" 是主语从句最常见的一种结构。例如:
    It is very clear that he's round and tall like a tree.
    It is strange that it hasn't been noticed before.真奇怪,它以前没有引起注意。
    2. It is v-ed that…=sb/sth is to do
    It is said (reported/ learned/believed/thought/known/told/hoped.....) that...

    It is a pity that he is ill. 他生病了,真遗憾!
    四、it作形式宾语
    当复合宾语中的宾语是不定式、动名词宾语从句时,往往把宾语放在它的补足语后面,而用it 作形式宾语,放在宾语补足语之前。
    该句型中的it 作形式宾语,常用的动词有think, believe, make, find, consider, feel等。
    I think it no use arguing with him.
    我认为和他争吵没有用。
