再来巩固下主谓宾It's my business to look after your health
1.这儿my business是形式主语,真正的主语是to look after your health因为主语是名词所以your health也要的 2.这儿用这个to是因为表示计划想好要做某事而且是主动 3.如果是被动是不是to就不用了,如:to refer to…as,如果不是因为被动把to给省略掉了,那这儿的to refer to中的第一个to又为什么没有呢People who work in offices are frequently referred to as 'white collar workers' for the simple reason wear a collar and tie to go to work.4.我知道这儿主语是不定式,不定式能做同位语和补语么,这儿to是business的同位语和补语么,这4个问题对么

好像有问题,It's my business to look after your health这一句中it是形式主语,替代“to look after —”的不定式短语,并有表强调的意思.
it作形式主语代替不定式短语.如:
It is necessary for us to learn something about the use of “it”.
对我们来说了解一些“it”的用法是必要的.
it作形式宾语
代替不定式(短语).如:
I found it very interesting to study English.
我觉得学习英语很有趣.
it强调句的几种强调情况
要强调句子的某一部分(通常是主语、宾语、状语)时,通常用 “It is(was)+被强调部分+that(who)+句子的其余部分”这种句子结构.强调部分指人时用who或that,指其他成分时用that.假如原来的句子为:
David bought a walkman from a store yesterday.
大卫昨天在商店买了一台随身听.
下面四个强调结构分别强调句中的主语、宾语和两个状语.
It was David who/that bought a walkman from a store yesterday.(强调主语 David)
It was a walkman that David bought from a store yesterday.(强调宾语walkman)
It was from a store that David bought a walkman yesterday.(强调地点状语 from a store)
It was yesterday that David bought a walkman from a store.(强调时间状语 yesterday)
