Question

I’m only brave when I have to be. __________ doesn’t mean you go looking for trouble.

A．To have been brave	B．Having been brave
C．Being brave	D．Be brave

Answer 1

C

试题分析：根据语法动词不定式和动名词的完成式都表示它们的动作先于谓语动词的动作，这里不符合句意，故排除AB；Be brave不能做主语，故排除，所以选C。
点评：本题难度适中。非谓语动词是近几年高考的热点，本题是对已学知识点的回顾，需要考生能够理解该题的语言环境，进而作出正确的判断。会判断非谓语动词与它的逻辑主语之间是什么关系，需要考生掌握非谓语动词的不同形式的用法区别等。
