Question

___ against cancer for many years, Steve Jobs, the co-founder of Apple, who died at the age of fifty-six, made technology fun.

A．Fighting

B．To fight

C．Fought

D．Having fought

Answer 1

D

试题分析：非谓语动词做状语，看它和句子主语之间的关系，并判断与谓语动词发生的先后。 Steve Jobs为句子的主语，与fight之间构成主动关系，排除Ｃ，从状语for many years可以得知fight发生在made之前，故用现在分词的完成式。故选Ｄ。Ｂ不定式位于句首只能做目的状语，与句意不合。
点评：非谓语动词部分的知识点除了记忆一些特殊的用法外,还要注意非谓语动词与逻辑主语之间的主被动关系。
