记忆方法
每年的：anniversary
该词源自拉丁语anniversarius，由annus'year’和versus'turning’两部分组合构成，整个词含有returning every year或the turn of the year之意。
因此，英语中的anniversary就很自然地被赋予了“周年纪念（日）”一义。
另一英语单词annual（每年的）也源于拉丁语annus。
词根词缀：-ann-年+-i-+-vers-转+-ary名词词尾→一年转一次；

小知识
When something is annual, it happens once a year. An annual holiday party should be a time for fun, but it also can be a sad yearly reminder of the passage of time.
An annual event happens every year: “I always forget to take sunglasses to my annual eye exam and am left wearing those horrible disposable shades.” Annual earnings are made over the course of a year: “His annual income is on a steady decline.” And an annual plant lives for only a year: “My neighbor Shirley always plants the most garishly bright annuals instead of more subdued perennials.” Whether it's eye exams, income, or plants, you can expect to see something annual again in about 365 days.
