请教英语语法结构
汤姆叔叔的小屋里有一句话：He was short,thick-set man,with coarse,commonplace features,and that swaggering air of pretension which marks a low man who is trying to elbow his way upward in the world.
请问：从and that...往后是不是一个并列句?如果是的话,它的主语是that swaggering air of pretension吗?
那么which marks a low man 是不是那个主语的主语从句?
who is trying to elbow his way upward in the world应该是修饰a low man的从句.
这样,and that...这个句子是不是就没有谓语了?
