Paul is the man who we believe has the best understanding of what it is that m
akes our products different from others on the market.
请问 what it is 中的 it is 可以省略吗？
that makes… 是形容词子句还是名词子句？
烦请解惑，感谢。

1. 如果要省略，it is that 要同时都拿掉2. 形容词子句 修饰前面的what

that 引导形容词子句，为何不直接放在what后面？it is是指什么？

句形是Paul ... best understanding of (something)然后 something = what it... market 这一句it is 就是指那个 what (倒装句) 那个what就是that makes our products different的东西原句是 It is XXX that makes our product different.现在XXX没写出来，用what代替。
