②(教材典句)No visitor would think it surprising that the island is a UNESCO World Heritage Site.

以上各句中it用作形式宾语,句①中it指代动词不定式短语,句②中it指代that从句,句③中it指代when从句。
[语法规则]
当动词不定式(短语)、动词-ing(短语)或从句作宾语时,为了保持句子结构的平衡,常用it作形式宾语,而将真正的宾语后置。此时it无意义。
it作形式宾语常用于以下几种情况:
1.动词+it+形容词/名词+(for/of sb.)+to do/从句
常用于该句型的动词有:think, believe, suppose, consider, feel, find, make, keep, regard等。

The professor considers it no good reading without understanding.
这位教授认为不理解便朗读不好。
He thought it no use trying to convince them.
他认为试图说服他们没有用。
3.动词+it+介词短语+that ...

Don't take it for granted that they will support you.
