考研英语长难句句子成分分析

考研英语长难句句子成分分析curbs on business-method claims would be a dramatic about-face,【because it was the Federal Circuit itself that introduce such patents with its 1998 decision in the so-called State Street Bank case】

问题：请把because引导的状语从句的句子成分划分一下，谢谢

Answer 1

because it was the Federal Circuit itself that introduce such patents with its 1998 decision in the so-called State Street Bank case
because引导原因状语从句，后面跟的是原因，这个从句中又有一个that的同位语从句。首先，主句it was the Federal Circuit itself的主语是it，谓语是was，宾语是 Federal Circuit，itself是同位语； that的同位语从句，先行词是itself，即the Federal Circuit, 充当从句主语；谓语是introduce，with后面是一串介词结构，表伴随；in后面是地点状语

追问

请问such patents 做什么成分呢

Answer 2

because it was the Federal Circuit itself that introduce such patents with its 1998 decision in the so-called State Street Bank case
because引导了个强调句，强调句要把it was....that...去掉，如果句子还完整，就是强调句。所以句子是这样的： the Federal Circuit itself introduce such patents with its 1998 decision in the so-called State Street Bank case，主语：the Federal Circuit itself 谓语：introduce

Answer 3

it was...that...是强调句吧
