26、“Thisorganizationsmeetings”可知，此处指作者参加志愿者组织的一次会议(meeting)。3答案与解析：A根据第一段的“PeertoPeer”和空后的“everyoneisconsideredapeer”可知，此处表示正如这个志愿者组织的名字表明的那样，这里的每个人都被认为是同龄人，因此该空用name。4答案与解析：A根据本句中的“bytheirfirstnames”可知，作者他们直呼领导们的名字。address在此是及物动词，表示“称呼(某人)”。5答案与解析：B由句中的“askourleadersforhelp”可知，在生活中有困难时可以向领导们求助，并且领导们从不

28、acandy”可知，作者参加的是一些有意义的活动，因此该空用meaningful“有意义的”。11答案与解析：C根据活动的主题“GiveacigaretteTakeacandy”可知，用香烟换糖，其目的当然是鼓励人们少吸烟。故C项decrease“减少”符合语境。12答案与解析：B由上文的“Atthisorganizationwearefriendswitheachother”可知，在这里作者他们彼此是朋友，此处应表示他们是一个亲密的团体，因此该空用tight“亲密的，密切的”。13答案与解析：B作者参加的这些志愿者组织确保自己有发展个性的绝好机会，因此该空用guaranteed“确保，保证”。14答案与解析：D根据全文的感情色彩和第一段中的“whichchangedmylife”可知，参加志愿者组织使作者的生活发生了巨大变化，因此此处指“让我的人生好得令人难以置信”。D项“非常好的，令人难以置信的”符合语境。15答案与解析：A作者相信随着年龄的增长，自己会有很多与青春有关的美好回忆(memories)。
