分析一下英语句子成分

Gold is precious only so long as enough people agree that it is

Answer 1

Gold is precious only so long as enough people agree that it is.
Gold 主语
is 系语（联系动词）
precious 表语
so long as enough people agree that it is 这个是so long as引导的条件状语从句，意思是“只要有足够多的人认为（同意）是”，从句里面的成分如下：
enough people 主语
agree 谓语
that it is 是that引导的宾语从句，这个宾语从句里面，it是主语，is是系语

Answer 2

Gold is precious only so long as enough people agree that it is.
这句话可以翻译为: 只要有足够多的人认为金子是宝贵的，那它就是宝贵的。

主语Gold
谓语 is
表语 precious
条件状语 so long as enough people agree that it is.
that it is引导的宾语从句做agree的宾语。
