从句语法 a connunications satellite is an artificial satellite stationed in space for the purposes of telecommunications和each of which provides a large-capacity communication channel分别什么从句?
前一句分为两部分:stationed in space 是定语从句修饰an artificial satellite ,省略了that或which,后边 for the purposes of telecommunications是介词结构状语后置,也是修饰an artificial satellite . 第二句定语从句,of是与前边each有关的,不影响从句.
