关于此句A选项，笔记中说第2个more than...是做前面的同位语，请哪位帮忙解释下，形容词也可以引导同位语么？

第一个more than和第2个more than的含义应该是不一致吧？more than...more than...这是一个什么特殊的结构么？

希望nn能帮忙解答！先谢过了！

应该不是同位语，只是一个补充修饰的成分，比如，you get an unbelievable score,much high than mine. 就是对前面的score 做一个进一步的补充说明

这两个more than不是特殊用法，凑巧比较工整一些~

多谢了！后来在做PREP的时候也遇到过类似的情况，就是一个修饰成分，而不是同位语。所以PREP笔记还是需要谨慎的去看。多谢了
