高手请帮忙分析句子！！

It might not be known to the public that the President was in poor health.
请分析这句话的语法重点

Answer 1

这句话主要考察主从句时态保持一致

主句 it might not be known to the public为一般过去时 (might)
意思为：公众可能不知道
从句 the president was in poor health也应该为一般过去时 (was)
意思为：总统身体情况很糟

另外，本句中it 代指the President was in poor health, 为避免主语过长, 将其置后构成主语从句。

Answer 2

主语是 the president was in poor health，整个句子是 主语从句。

Answer 3

it 代指the President was in poor health, 因为主语太长,所以必须置后,须加THAT. 这种句型叫做主语从句.

Answer 4

整个句子是个主语从句，重点嘛，也就是这个主语从句并且其中the public做了先行词后面又引导了个限制定语从句。

Answer 5

主语从句
