定语从句在春节场景中的应用

通过'饺子（dumplings）which symbolize wealth'等典型表达，掌握which/that引导的限制性定语从句。特别注意当先行词是'tradition/custom'等抽象名词时，关系代词选用that更符合英语母语者习惯。对比分析'The lion dance that originated in Han Dynasty'与非限制性从句'Spring Festival, which falls on lunar January 1st'的用法差异。

现在完成时的节日语境

描述春节习俗延续性时，'Families have gathered for reunion dinners for over 2000 years'完美呈现has/have+过去分词结构。需注意'since+时间点'与'for+时间段'的搭配区别，如'People have worn red clothes since ancient times'和'The custom has existed for millennia'。该时态特别适合表达年俗的古今传承。

被动语态的文化表述

在说明春节传统时，被动语态能突出文化主体性。例如'Red envelopes are given to children for good luck'比主动语态更符合英文表达习惯。重点训练'be+过去分词'结构在不同时态中的变化，如过去时'The lantern festival was first celebrated in Han Dynasty'与现在时'Zongzi are made with glutinous rice'。
