Question

英语语法：请从语法角度分析这个句子的成分。

So we should realize how ridiculous it is that we are wasting food without limitation.

Answer 1

we是主语；should realize是谓语；how ridiculous it is that we are wasting food without limitation是宾语从句; ridiculous是表语； it 是形式主语；that we are wasting food without limitation是主语从句

Answer 2

1 we (主语)should realize（谓语） how ridiculous it is that we are wasting food without limitation（宾语）

2 how ridiculous （表语）it（形式主语） is （系动词）that （主语从句连接词）we are wasting food without limitation（真正主语）

3 你的句子是 宾语从句（+主语从句部分）

Answer 3

it is riduculous that we...it 这里作为形式主语，that后面所跟的整个从句才是真正的主语。

we should realize how...这一句就是how引导的宾语从句。

Answer 4

we should realize 后边是宾语从句
how ridiculous it is . it做形式主语，真正的主语是that从句的内容

Answer 5

realize后面是宾语从句。
而that后面又是主语从句，it是形式主语。
