复合词构成规律：修饰词+核心名词=新的复合名词
1.组合方式:左边的词(多为名词/形容词)+右边的词(多为名词) =新的复合名词。green (形容词)+ huse (名词)= greenhuse (温室)sand (名词)+ strm (名词)= sandstrm (沙尘暴)2.语义逻辑:前一个词用来修饰 / 限定后一个词,表达一个更具体的概念。high (高的)+ way (路)= highway (高速公路，即 “高等级的路” )farm (农场)+ land (土地)= farmland (农田，即 “用于农场的土地” )rail (铁轨)+ rad (路)= railrad (铁路，即 “铺有铁轨的路” )

本单元的写作围绕“变化”这一核心主题展开，引导我们从个人生活与生态环境两个层面，用今昔对比的方式记录变化，并在变化中提炼不变的精神内核：在个人生活变迁的微观视角上，以学生从小学到初中的成长为载体，从上学方式、居住环境、学习模式等方面，用used t... Nw...句型描述具体变化；在生态环境变迁的宏观视角上，以塞罕坝的绿色奇迹为典型案例，展现生态治理的宏大变化；写作核心要求为采用“个人变化＋环境变化＋不变内核”的三段式结构，用对比逻辑清晰呈现内容，熟练运用used t... Nw...句型描述今昔差异，结合单元词汇(如sandstrm, bush, capital等)丰富表达，并在描述变化的基础上点明“变化中的不变”——个人层面的亲情与社会层面的奋斗精神，让文章有温度、有深度。
