3. 用于强调结构 要强调句子的某一部分, 通常是主语、 状语、宾语, 可以把it当作先行词。 这种句子的结构是：
“It is/was+被强调部分+that/who+句 子的其他部分”。如果强调的是人, 可以用who, whom代替that。
e.g. It is Prof. Lin who teaches us English. (强调主语) It is English that Prof. Lin teaches us (强调宾语) It was in Shanghai that I saw the film. (强调状语) It was in 2001 that I went to university. (强调状语)
there → it
