问题补充：

that he has wasted too much time, the boy is determined to stop playing video games.

A. Realized

B. Realizing

C. To realize

D. Having realized

答案：

A. Realized

(答案→)B. Realizing

C. To realize

D. Having realized

解析：考查非谓语动词。主语the boy与realize之间是主动关系，故排除A。这里分词作伴随状语，故C不正确；realize与be determined to几乎同时发生的动作，故不需要用现在分词的完成式。
