Another issue is that, while climate change is well integrated into some subjects and at some ages-such as earth and space sciences in high schools - it is not as well represented in curricula for younger children and in subjects that are more widely taught, such as biology and chemistry.Another issue is that, while climate change is well integrated into some subjects and at some ages-such as earth and space sciences in high schools - it is not as well represented in curricula for younger children and in subjects that are more widely taught, such as biology and chemistry.Another issueisthat, 【whileclimate change is[well]integrated intosome subjectsand at some ages-{such as earth and space sciences in high schools} - itis not as well represented[in curricula for younger children] and [in subjects(thatare[more widely]taught), {such as biology and chemistry}】.[主干]Another issue is that...“另一个问题是...” ，主系表结构|--[状语从句--从句]while climate change is well integrated into some subjects and at some ages“尽管气候变化很好地融入了一些学科和某些年龄段的教学中” ，让步状语从句 while“表尽管、虽然”|--[插入语]such as earth and space sciences in high schools“例如高中阶段的地球和空间科学” ，进一步解释是什么学科，什么阶段的孩子|--[状语从句-主句]it is not as well represented in curricula for younger children and in subjects that are more widely taught, such as biology and chemistry |--[谓语]is not as well represented“没有被很好的体现”，被动语态 |--[状语1]in curricula for younger children”更幼年儿童的课程里” |--[状语2]and in subjects that are more widely taught “在教授范围更广阔的学科里” |--[定语从句]that are more widely taught 修饰前句的subjects,并运用被动语态 |--[插入语]such as biology and chemistry“例如生物学和化学”is not as well represented 1、区分下curriculum，subject
curriculum（课程）是宏观的整体规划，而 subject（科目/学科）是微观的具体分类
这里用的是复数，指的是针对不同年龄段的一整套教学计划。
curricula for younger children 意思是"针对低龄儿童的整套课程方案"。这是一个宏观的计划，不仅包括教什么学科，还包括怎么教、用什么教材、达到什么目标。
这里指的是具体的学科门类。
subjects that are more widely taught 意思是"教授范围更广的具体学科"。它强调的是一个个具体的知识领域，比如生物、化学。
2、represent 在这句话的语境中，它既不是最常见的“代表”，也不是“象征”。
在这句话里，represent 最准确的理解是：（被）包含、（被）体现、（被）涉及= be included 或 be covered
1、“得意”--得到了句子的灵魂，获取核心意思与逻辑本句主要指出关于气候变化，教育的覆盖面不均衡；虽然它已经较好地融入了高中的地球与空间科学，但在低龄阶段的课程中，比较起生物、化学这些基础的学科里，气候变化的内容仍然相对缺失。
另一个问题是，尽管气候变化议题已经很好地融入了某些学科和特定年龄段的教学（例如高中的地球与空间科学），但在低龄学生的课程中，以及在生物、化学等教授范围更广的学科里，它的体现还远远不够。
