That he will refuse this piece of advice is impossible.
It is impossible that he will refuse this piece of advice.
It作形式主语 句1的主语是从句That he will refuse this piece of advice是正常的语序，放 在句首。但是这样的主语会给人一种头 重脚轻的感觉，所以为了保持句子的平 衡，常用it作形式主语置于句首，而将真 正的主语放在句尾，如句2。
句1中表语为名词a pity/shame。句2中表语为形 容词impossible。
常用的名词有：a pity, a wonder, a good thing , a surprise, an honor, a miracle, a secret, common knowledge ... 常用的形容词有：necessary, obvious, wonderful, unusual, surprising, ertain, worthwhile... （记忆技巧：p,wonder,good,s和miss know.n,o,won,u 是e, worth.）
真正 主语
be+表语（表语：名词， 形容词）
It
不及物动词
主语 从句
be+过去分词/动词的被动语态
记忆技巧：“it”形“从”真，成句型，主语从句构成形。

Her job is teaching. What she does is teaching.
句1和句2中is teaching是系表结 构，所以句1的主语是Her job,句 2的主语是What she does。句2 的主语是一个句子。
