it做形式主语的问题
比较下面2个句子:
It's necessary to take exercise .
The chair looked rather hard, but in fact it is very comfortable to sit on.
对第一句来说,it做形式主语,真正的主语是不定式,改过来应该是 To take exercise is necessary.但是在第二句中,如果it也是形式主语的话,那么应该也有不定式做真正的主语吧,但把不定式直接放到前面的去变为To sit on is very comfortable.好像少了点什么吧?为什么呢?求解释!
it在it is adj to do句型中非得做形式主语吗??理解为代词,代替前面某个词(这里代chair)不可以吗?

第二句你看错了.it=the chair
The chair is comfortable to sit on.
英语中的句型:It's +adj.to do sth.---Sth is +adj.to do.如:
It's hard to learn English.=English is hard to learn.
由于夲句用it代替了the chair,故带来了一定的麻烦.
