2. It's a tragic stry that began in 1810 when humans arrived n the island. （教材p50）（本句是一个强调句，强调主语a tragic stry）这是一个悲惨的故事，始于1810年人类来到岛上。
在英语中，有时候句子的宾语比较复杂，很容易引起歧义。因此，为了平衡句子结构，避免误解，习惯上使用一个没有具体意义的代词it来作形式宾语，而将真正的宾语放在后面，这时，共分为两种情况：第一种情况为it后接宾语补足语；第二种情况为it后不接宾语补足语。如：1．I fund it imprtant t learn spken English.2．Rumr has it that the defence minister will sn resign.
