明确目的说明文章想要展现的个人/家乡变化，表达对比今昔的写作意图，写出自己从这些改变中感受到的成长与时代感悟。◆个人背景简述与变化相关的过往经历，比如自己过去内向不爱发言、家乡从前道路狭窄交通不便等，使用usedto句型交代旧时状态，为后文对比铺垫。

情感表达通过细节描写凸显对成长、家乡发展的真切感受，传递珍惜当下生活、感恩时代进步的正向情绪，强化文章感染力。

总结升华礼貌收尾概括全部变化，总结自身收获，抒发对未来生活、家乡发展的美好期盼，完成全文立意升华。主题写作写作思路开头总起点题：开门见山说出人/家乡发生了巨大变化，直接点明本文将对比过去与现在，引出下文对比内容。中间①描写过去的模样用usedto句型描写旧时状态：个人可写过去性格、爱好、学习习惯；家乡可写从前交通、环境、娱乐方式，铺垫旧生活细节。②对比如今的现状结合现在完成时写当下改变：写自身性格、能力的成长；或家乡道路、高楼、休闲设施的发展，写出生活变好的具体体现。③变化带来的收获分别写个人成长的感悟、家乡发展带来的便利，体现变化带给自己的积极影响。结尾抒发感悟：总结今昔对比带来的触动，感恩成长与时代发展；展望未来：表达对自己、家乡未来变得更好的期待。主题写作词汇运用1.利用词汇如change,usedto,past,now,different,memory,hometown,grow来表达今昔对比的写作核心意图，点明主题是人与环境的变化。2.使用

live,walk,travel,study,communicate,develop,improve

等动词搭配短语，描述过去与现在的生活方式、行为习惯。3.提及inthepast,nowadays,astimegoesby,besides,what’smore,however,greatly等连接词与副词，划分过去、现在两层内容，让对比逻辑清晰、行文层次丰富。4.用quiet,crowded,convenient,shy,outgoing,simple,modern,comfortable,hard,amazing等形容词丰富细节描写，刻画出过去、现在截然不同的场景与人物状态，让文章画面更生动、更有感染力。主题写作写作练习假设你是李华，你的英国笔友George来信询问你家乡近十年的变化。请你根据以下提示，用英语给他写一封回信。注意：1.词数100左右；2.可适当增加细节，以使行文连贯；3.开头和结尾已给出，不计入总词数。内容要点：1.交通：过去道路崎岖，现在新修公路，出行方便；2.住房：过去住小平房，现在搬进宽敞的新居；3.环境：过去山上光秃，现在绿树成荫；4.教育：新建了学校图书馆和多媒体教室；5.你的感受。DearGeorge,I’mgladtoreceiveyourletter.Youaskedaboutthechangesinmyhometown.Letmetellyousomethingaboutthem._____________________________________________________________________________________________________________________________________________________________________________________
