each of which引导从句,拓展了句子意思,避免了run-on错误;called 修饰 the opening, located 修饰projection。
考点:句子结构(Grammatical Construction), 逻辑表达(Logical Predication), 指代一致(Agreement) 若划线部分采用each of them,则不能出现谓语动词,否则句子出现多套主谓,构成run-on sentence的错误。这种情况下可以采用独立主格结构。另外一种解决方案是用which替代them, 构成非限定性定语从句,进一步扩展句子意思 该句多个从属关系、修饰关系并存,在建构句子时要保证修饰关系清晰正确each作主语为单数,要求单数谓语
