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.(形式主语居多)**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 + BSVO=A+B而且通常情况下 It is/was……是强调句同位语从句同位语的实质 n1,n2—n1=n2S,n,VO.=S,引+svo,VO前面的成分不应当在后面充当成分。The fact, that the ancestors of birds are dinosaurs, is known.可接同位语的名词多为抽象名词，例如：view/idea/suggestion/fact/reason/conclusion……**同位语和定语从句的区别同位语的句子中，前面的成分不应当在后面充当成分。The fact, that the sun is round.定语从句中，引导词充当成分。The book, that you bought for me. “that”充当宾语。ExampleIt is generally accepted that the single super continent known as Pangaea indeed existed, that Pangaea subsequently broke apart into two giant pieces, Gondwanaland in the south and Laurasia in the north, and that the continents attached to the various crustal plates separated and drifted in various directions.人们普遍接受，Pangaea 以一个特别大的陆地形式存在，后来他被分为两个大块，在南边的Gondwanaland 和在北边的Laurasia，他和那些在不同地壳上的大陆分开了并且向不同方向上漂移。**如何找出复杂句中的谓语？先找引导词，然后去掉随后的动词，还有动词的话，这个动词就是谓语。2、形容词性从句=定语从句引导词 （1）that/which/who(whom)（代词性）（2）whose/when/where(非代词性)结构 （1）that/which/who(whom)=S+VO=a.This is pig that/which is very fat.（1）that/which/who(whom)=O+SV=a.因为代词性的引导词可以充当主语或宾语This is the pig that/which I ate.(作宾语可省略引)This is the pig from which I make fun.引导词前的介词取决于后面的动词This is the pig,which is very fastThis is the pig, (which)I ate.This is the pig, from which I make fun.（2）whose/when/where(非代词性)+SVO=a.The book, whose cover is red, is quite interesting.This is the place where(=in which 定语从句) I grew up. When 用在后面也可能是状从,也有可能是定从。**具体分析举例In his hypothesis that he developed based on it……看上去该句的based 是一个n-ed的形式，但是她又是修饰谁呢？In his hypothesis() he developed that based on it….因此可以看出，base
