It 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 fast

This 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，based 修饰that，而在此句中，that指代 hypothesis。

**形容词性从句的省略

当that/which在定语从句中充当宾语时，可将其省略。

This is the pig that/which I ate。

This is the pig I ate。

当that/which在定语从句中充当主语时，且从句的谓语动词为be动词时，可将其同时省略。

The house, which was built in 1919,was destroyed。

The house, built in 1919,was destroyed。

**个别情况下，which/as在引导定语从句时，也指代前面整个一句话。
