President Obama told television viewers that he saw ______ as his duty to run for a second term.

A．one

B．that

C．this

D．it

答案

D

解析

试题分析：考察it作为形式宾语。本句指的it是形式宾语，真正的宾语是后面的不定式to run for a second term。在英语中只有it可以作为形式主语或形式宾语。句意：奥巴马总统告诉电视观众他把做第二任总统当成是自己的职责。故D正确。
点评：it做形式宾语，通常和下列动词连用： consider, think, make, find, believe,  feel, guess...。一般说来，当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末。
