【翻译原文】
中国的重阳节(Double Ninth Festival)由来已久。人们普遍认为重阳节源于“辟邪”(warding off evil)。 这一天的活动，包括登山、赏菊(chrysanthemum)、喝菊花酒等。随着时间的推移，它变成了一个庆祝的节日。 这天，家人团聚在一起，也会纪念家族的祖先。1989年，我国把这一天定为老人节(Seniors' Day)，表达我们对老人的尊敬与爱戴，使这个节日在新的历史时期继续发挥文化传承的作用。
1.第1句中的“由来已久”可用has a long history来表达。
2.第2句中的“人们普遍认为”可以直译为people commonly believe that，但英语更为地道的表达是it is widely believed that，因为根据上下文来看，施动者不言自明，故没必要译出。
3.第5句“这天，家人团聚在一起，也会纪念家族的祖先”，可译成用and引导的并列结构people come together for family reunion and remember their ancestors.
4.第6句中的“我国”可直译为our country，但因为此动作属于政府行为，故译成the Chinese government更准确。“把这一天定为老人节”可套用结构make sth. sth.（使……成为……），故表达为made this day Seniors' Day.因本句较长，结构复杂，宜采取“分译”法，故“使这个节日……”另起一句。
