1）新定义3|4：
Peoplewho work in offices are frequently referred to as "white|collar workers'for the simple reason that they usually wear a collar and tie to go to work.
Such is humannature, that a great many people areoften willing to sacrifice higher pay for the privilege of becomingwhite|collar workers.
2）新定义3|27：
Thereare times when we would willingly give everything we possess to save our lives,yet we might grudge paying a surgeon a high fee for offering us precisely thisservice.
Theconditions of society are such that skillshave to be paid for in the same way that goods are paid for at a shop. Everyonehas something to sell.
请教语法网的专家们：
a）上面2句都出现了suchthat，新定义书上都将这2种剖析为such+ that 同位语从句，是不是正确？？
b）上面2个句子中的such分别是什么词性？到底指代了“什么”？？非常困惑！
c）怎么样正确理解剖析1）新定义3|4中的such,that 语法含义？？又该怎么样正确理解剖析2）新定义3|27中的such,that语法含义呢？？二者是一样的吗？
麻烦专家老师们答疑解惑，谢谢！

此句中，such 为代词，指代前面提到的，如大家喜欢做白领的心态，或许是出于虚荣或面子等缘由。 that 引导结果状语从句。that =so that.

依据《朗文词典》：
