语篇解读：本文是一篇说明文，主要介绍了中国的传统节日重阳节的历史发展、名称由来等。
1．on 重阳节是在农历九月初九这一天。在特定的某一天用介词on。
2．is regarded 在中国，九被视为阳数。主语nine和动词regard之间是被动关系，表示“被视为”，故用被动语态；此处是对客观情况的描述，应用一般现在时。
3．how 九月的第九天含有两个阳数，“重”在汉语中表示“双倍”的意思，这就是重阳节名称的由来。根据语境可以判断，设空处表示“重阳节名称的由来”，故用how引导该表语从句。
4．formally 根据设空处后的动词set可知，设空处修饰该动词，故用副词形式。
5．declared 根据该句中的时间状语“In 1989”可知，该句陈述的是发生在1989年的事情，故用一般过去时。
6．the the＋形容词，表示一类人。the elderly表示“老年人”。
7．themselves 1989年，中国政府宣布农历九月初九为“敬老节”，以此来尊敬老人，并让他们过得愉快。enjoy oneself为固定搭配，意为“过得愉快”。
8．being promoted 根据设空处前的介词of可知，设空处用动词的ing形式；根据语境可知，主语people和动词promote之间是被动关系，表示“被提升”，故用being promoted。
9．disasters 人们常常认为菊花酒能消除各种疾病和灾难。根据该句中“diseases and”可知，设空处用复数形式。
10．to show 如今，人们举办许多活动如组织老人旅游、给老人送礼物以表达对老人的尊敬。根据句意可知，设空处表示目的，故用动词不定式。
