【问】 (1) News services make____for newspapers to give their readers news from aroundthe world.

A. it is possible B. it possible

C. possible D. possible that(TOEFL，87.12)

(2) A microphone enables a soft tone to be amplified，thus making it possible the gentle renditions of romantic love songs in a large nall. (TOEFL，91.10)

为什么试题(1)要求用it (make it possible)，而在试题(2)中却要求取消it (make possible)?

【答】 首先要明确试题(2)的语法结构：名词短语the gentle renditions...是宾语，而possible是宾语补足语。由于宾语长，宾语补足语短，而将宾语补足语提到宾语的前面去了(参见ob-ject complement²)。其次应当牢记，只有动词不定式、动名词或从句充当宾语时，才需要用it来作它的形式宾语，如试题(1)。而名词短语充当宾语时，是不需要用it来作形式宾语的，如试题(2)。
