it's up to everyone to decide what is right for them.帮我分析下句子

1.It's up to everyone to decide what is right for them.
It是形式主语,不定式短语to decide what is right for them是真正的主语.
is up to everyone是系表结构,做句子的谓语.
不定式中,what is right for them是decide的宾语从句.
2.三楼解释基本正确.
She是主语；
was looked after是谓语；
by her mother是状语.

这个句型是形式主语句型 It is up to sb. to do sth. 中文意思是：由某人决定做某事
it 是形式主语，to decide what is right for them 是真正的主语，原来句子应该是这样的：To decide what is right for them is up to everyone. 意思是: 由每个人自己决定什么对自己是合适的。
He...

我的理解是想表达的意思是谴责她忽视你的努力有什么不对吗. what is wrong to condemn her for her overlook your hard work.

属于一般陈述句。it是主语，is是谓语，up to you是宾语，to decide是动词不定式做状语，what引导的从句是decide的宾语，所以是宾语从句，从句中what是主语，后面自己应该会了吧。
