下边，大家就看来一个简易的事例吧。
Therefore，if the Earth began as a superheated sphere in space, all the rocks making up its crust may well have been igneous and thus the ancestors of all other rocks.
(独特构造may well have been――可能是)
因而，假如地球上刚开始时是外太空中一个超温的圆球，那麼全部构成地表的岩层都可能是火成的，因而变成全部别的岩层的先祖。
分析：
主句：all the rocks may well have been igneous and thus the ancestors of all other rocks
从句1：if the Earth began as a superheated sphere in space
从句2：making up its crust
主句中2个宾语一部分igneous和the ancestors of all other rocks并排
从句1做为标准状语从句，装饰主句
从句2非谓语动词后置摄像头装饰主句中的主语rocks
名词性从句 主语从句 宾语从句 同位语从句
引导词 (what/how/that/why/whether)
构造 主语从句
what VO=n. for eg
what SV=n. What you said is right.
形式宾语 Make it possible for sb.to do ?
that/how/why/whether SVO=n.
That the ancestors of birds are dinosaurs is known.It is known that the ancestors of birds are dinosaurs.(形式主语占多数)
形式主语和强调句的区别
形式主语 It v (that SVO)=n.
n.=it
强调句 It is/was A that B
SVO=A B
并且一般状况下 It is/was……是强调句
同位语从句
同位语的本质 n1,n2―n1=n2
S,n,VO.=S,引 svo,VO
前边的成分不理应在后面当做成分。
The fact, that the ancestors of birds are dinosaurs, is known.
可配同位语的专有名词多见抽象名词，比如：view/idea/suggestion/fact/reason/conclusion……
同位语和定语从句的区别
同位语的语句中，前边的成分不理应在后面当做成分。
The fact, that the sun is round.
定语从句中，引导词当做成分。
The book, that you bought for me. “that”当做宾语。
