  下面是和谐英语网整理的2021托福阅读指导之从句例子整理,供大家参考。

  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.

  (特殊结构may well have been——可能是)

  因此,如果地球开始时是太空中一个过热的球体,那么所有组成地壳的岩石都可能是火成的,因此成为所有其他岩石的祖先。

  解析:

  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

  主句中两个宾语部分igneous和the ancestors of all other rocks并列

  从句1作为条件状语从句,修饰主句

  从句2非谓语动词后置修饰主句中的主语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)

  结构 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 + B

  SVO=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=n2

  S,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。
