【题目】_________a few activities successfully, Jackson becomes much more confident about himself and determines to be a host.
A.OrganisingB.Having organised
C.OrganisedD.To organise
在线课程【答案】B
【解析】
考查非谓语动词。句意：已经成功地组织了一些活动，Jackson对他自己变得更自信，并决定当一个主持人。分析句子可知，此处应用非谓语动词作状语，逻辑主语Jackson和organize之间是主动关系，且该动作发生在谓语动作“变”之前，应用现在分词的完成式having done，故选B项。
