No plan should ever be so rigid that it is unable to adapt...句子结构分析
No plan should ever be so rigid that it is unable to adapt to changing circumstances.As your career develops,opportunities will arise,and you will have choices to make that may lead you down quite different paths from those which you originally envisaged.
我看解析说最后一个that 定语从句是修饰前面choices ,我也认为可以理解.但是不理解的是choices是复数,怎么用that去修饰复数呢?
是最后一个that啊

that 并非定语从句的引导词,而是so...that(如此……以至)句式中的that,
句子的意思是:
任何计划都不应如此僵化,以至于其不能够适应境况变化

that本来就可以修饰复数啊!
