答案选B.determining
determine一词的现在分词形式在句中作伴随状语.又如：
He telephoned his parents,telling them that he was getting on well with his new job.
欢迎提问,答案好像是A。能否帮忙确认一下。谢谢继续回答：答案如果是A，就应在determined前加一个and,使 determined与 has learned 构成并列谓语 ，否则就是答案不对。又如：He telephoned his parents, and told them that he was getting on well with his new job. 欢迎追问，乐意解答；愿你满意, 望你采纳。
