(lǐng)導(dǎo)能力，培養(yǎng)了性格并支持了社區(qū)活動。41．答案與解析：C參加殘疾人奧運(yùn)會游泳比賽的志愿活動對作者來說有特殊的意義，because后的內(nèi)容說明作者在該活動中提高了領(lǐng)導(dǎo)能力，培養(yǎng)了性格并支持了社區(qū)活動，這些便是其意義所在。故選C項。42．答案與解析：D根據(jù)上文中的“helpedimprovemyleadershipskills”和本段中的“independentlydirectedeachswimmer”可知，此處指作者的領(lǐng)導(dǎo)力得到提高。故選D項。43．答案與解析：A此處指需要在比賽時通知每位參賽者什么時候開始游。inform意為“通知”。故選A項。44．答案與解析：A根據(jù)設(shè)空處后的“readytoperform”可知，此處指作者必須確保每個運(yùn)動員就位，bepositioned表示“已就位”。故選A項。45．答案與解析：C因為作者要確保游泳運(yùn)動員就位，所以作者需要知道每場比賽的時間和地點。故選C項。46．答案與解析：D此處與第一段三個意義中的“developmycharacter”呼應(yīng)，指志愿活動影響了作者的性格。故選D項。47．答案與解析：B雖然他們身有殘疾，但大多數(shù)游泳運(yùn)動員都比作者游得好，這給作者留下了深刻的印象。impressed意為“有深刻的好印象”。故選B項。48．答案與解析：D不管運(yùn)動員們是輸是贏，他們積極的態(tài)度使作者感到吃驚。故選D項。49．答案與解析：C此處指作者在此次志愿經(jīng)歷中擴(kuò)大了視野，有機(jī)會去遇見那些平時不能遇到的人。故選C項。50．答案與解析：A當(dāng)看到參賽者熱情洋溢的面孔時，作者感到自己的付出是值得的。rewarding意為“有意義的；值得做的”。故選A項。51．答案與解析：C此處呼應(yīng)第一段三個意義中的“supportmycommunity”，指為社區(qū)作貢獻(xiàn)。故選C項。52．答案與解析：D擔(dān)任志愿者給了作者一個改善社區(qū)的機(jī)會，使他熟悉了居住在這個社區(qū)的人們。becomefamiliarwith意為“熟悉……”。故選D項。53．答案與解析：B本文的主題是志愿活動的意義，據(jù)此可知，此處指志愿活動的重要性應(yīng)該被強(qiáng)調(diào)。故選B項。54．答案與解析：D根據(jù)空后內(nèi)容可知，此處指作者為自己能參加志愿活動而感到幸運(yùn)。故選D項。55．答案與解析：B本文主要講述了
