内文: This chapter analyzes some of these factors, shows where improvements are
most sorely needed, and points to the directions where we shall be looking for
solutions in the rest of our journey.

where improvements are most sorely needed.
多加了个where让我觉得很不自然，感觉这句应该不是个完整的句子?
improvements are most needed.
这句我没问题，进步是最需要的
where improvement are most needed.
哪里进步是最需要的(???有点怪怪的)
还请各位帮忙解惑，谢谢

请连 show 一起看，这句是名词子句，是 show 的受词，整句意思是“显示出非常需要改进的地方”，where 类似“的地方”，其实就算翻“哪里/什么地方”在中文也不会看不懂：“（本章）显示出哪里/什么地方是非常需要改进的”

谢谢你!!!!!!!
