你问题还比较有代表性,问了这么多,说明你是个爱学习的孩子,挑重点的说了,像标点符号、语序之类的就不详细回答了,建议你对语义类小问题先自己去查字典,实在不懂的语法类再问别人,学英语要“求大同,存小异”,大块的语法一定要搞清晰,小疑问慢慢随着学习的提高以后自然会理解.
at one time "一度、曾经",像这种状语类位置跟副词一样灵活,如果做插入语用逗号.
enjoy享有（利益、声誉.）、这里指的是享有高度的文明.
must have been 过去在完成时,情态动词中表肯定推测must,can,could,may,might都可表推测.其中must的可能性最大,can/could次之,may/might最小, 疑问和否定中只用can和can't,must在这里表示肯定推测.
for是并列连词,放在另一句后作补充说明原因,because是从属连词,放在主句前引导原因状语从句.
岛的名字叫kea
用破折号内的部分做插入语可对之前的部分做补充说明,跟中文一样.
beneath和under 可以互换.
worship还有礼拜的意思
两个词你都打错了,sacred和holy可以互换
date from追溯到,始于.现在分词做后置定语,
even then 即使在那时,不是现在
双手支撑在臀部,就是双后叉腰.可以用put 但没有支撑形象.
是turn out to,原来是,竟然是,为系动词短语
