而且让作者在发生车祸后无论是心态还是生活上都有了积极的改变。由此推知,志愿者工作带来了“双赢”的结果。故选B项。11.C 解析:标题归纳题。根据最后一段的“Thejourneybackhasbeenpainfulbutworthwhile.Now,fourteenyearslater,Iamadifferentperson.”可知,是志愿者工作让作者在车祸后接受了自己,找回了自己,志愿者工作对作者的意义重大。文章前面的段落也是围绕着作者的志愿者工作展开介绍的。因此,C项“志愿者工作:回归之旅”符合文章主旨,是最佳标题。故选C项。【帮你拓知识】重点语块①anarmyofvolunteers一大批志愿者②mentaldisabilities心理障碍③turn...around扭转;好转
