3.____is mentioned above ,the number of the students in high schools is increasing. a. Which b.As c.That d.It

我知道了答案 但却不知道为什么 我想要解释
第2道选择题是不是
it is ....that 的强调句型?

1. 在“序数词、最高级形容词、the only、the very + 名词”后面，定语从句确实要用 that 而不用 which.
2. ... that the moon travels round the earth once every month 是主语从句，位于句尾，而句首用 it 作形式主语。
3. 你或许已知道 which 引导非限制性定语从句时可以指代整个句子，如：The number of the students in high schools is increasing, which is mentioned above.
而 as 也有这一用法，且与 which 不同的是，which 从句只能位于主句之后，as 从句可在主句之前或之后，甚至插在主句中。
The number of the students in high schools is increasing, as is mentioned above.
As is mentioned above, the number of the students in high schools is increasing. （即本题）
The number of the students in high schools is, as is mentioned above, increasing.
as 的这种情形常见的还有：
As we all know, the moon travels round the earth once every month.
As is known to all, the moon travels round the earth once every month.

1 that 用法 the very接that表强调
2 it 用法 it作形式主语
3 as 用法 as引导的非限制性定语从句 as修饰后面整个句子

补充回答：
It 作形式主语和it引导强调句的比较
It 作形式主语代替主语从句，主要是为了平衡句子结构，主语从句的连接词没有变化。而it引导的强
