The construction of the Great Wall was not that

The construction of the Great Wall was not that easy, and drew heavily on the local resources for building materials.这个句子中的and为什么要改成which啊？and连接不也可以吗？

Answer 1

不可以。and是连词，必须连接两个完整的句子，用and的话后面的句子缺少主语。

追问

请问and除了连接动词之外还能连接什么词呢？

追答

不是连接动词，是连接两个完整的句子，完整的句子必须有完整的成分，比如主谓宾、主系表等。

你这题考的是非限制性定语从句的考点。

Answer 2

语感问题拉。明显是用which读起来更通顺。用and也可以理解，就是总觉得读起来怪怪的，逻辑不顺畅。

Answer 3

既然用逗号隔开，说明这是两个句子，但 and 后面的句子没有主语。有两种改法：
* 改为并列句 The construction of the Great Wall was not that easy, and it drew heavily on the local resources for building materials.
* 改为非限制性定语从句 The construction of the Great Wall was not that easy, which drew heavily on the local resources for building materials.

Answer 4

根据本句内容判断，本句如果用and则是并列两个句子，drew前面应该加it。本句用which引导的是非限制性定语从句，说明前面整个句子的内容。

一般来说，which 引导的非限制性定语从句，也可以用and 加并列句表达。例如：
In the presence of so many people he was little tense, which was understandable.
=　　In the presence of so many people he was little tense, and this was understandable.在那么多人面前他有点紧张，这是可以理解的。
