  托福阅读中常见句型结构剖析

  一、英语句子结构的原则

  1、谓动单一性原则 在一个句子里,有且只有一个谓语动词。

  2、主句单一性原则 在一个句子中,有且只有一个主句。(从句可以有若干个)

  二、三大从句

  1、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 It + v + (that +SVO)=n.

  n.=it

  **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。
