Question

It is worth considering what makes “convenience” foods so popular，and ________better ones of your own.

A．introduces	B．to introduce
C．introducing	D．introduced

Answer 1

C

试题分析：句意：什么使快餐饭如此受欢迎值得考虑，也值得引进自己更好的食物。it是形式主语considering ...and introducing...：整段是真正的主语；what makes "convenience" foods so popular：是considering的宾语从句；introducing 和considering 是并列的，用在worth的后面，表示“值得做”。故选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。
即学即练：John is the only one of the students in the class that never ________ a mistake even when it is pointed to him.
A. admit making    B. admits making   C. admit to make D. admits to make
解析：B。admit doing表示“承认做过某事”的用法。定语从句中that代替the only one作主语，谓语动词用第三人称单数形式。
