During the Mid-Autumn Festival in China, families gather to admire the shining noon and enjoy delicious mooncakes.
句中用的是the Mid-Autumn Festival,可以改用 the Mid-Autumn Day 吗?
Mid-Autumn Festival 可以换成 Mid-Autumn Day,前者(多见于国外的出版物)比后者(多见于国内的出版物)更普通,且前者通常要用定冠词,而后者通常不用定冠词。比较:
The Mid-autumn Festival is a time for family union. 中秋节是家庭团圆之时。
The days are getting shorter and shorter after Mid-Autumn Day. 中秋节过后白昼就越来越短。
