选A，请问怎么才算是run on错误？prep解释写的：

1. Intar has moved away from the Spanish classics and now draws on the works of contemporary

Hispanic authors.

2. Intar has moved away from the Spanish classics, and now it draws on the works of

contemporary Hispanic authors.

第一个句子中and前没有逗号,因此and连接的两个并列句中第二个并列结构应该省略重复的主语.
而第二句子中and前有逗号,因此and连接两个独立的句子,每个句子都需要自己的主谓宾,因此第二个句

子中的it不能省略.

这个A选项不就是and前面没逗号，而连接了2个句子吗？算run-on吗？

and的作用就是连接并列结构啊，所以and前后要严格对称（时态、结构、形式等等）：A选

项里面and前后都是完整句子，并列在although之后，没有语法问题。至于主语，这两个句子没

有共用主语啊，一个是company,一个是sales，所以没有办法省略啊~

B：and前后句子时态不一致；
C：and前后句子时态不一致；its指代不清楚；company's表达不好；
D：and前后不对称；语法上面首先having done很少放在句首修饰，而且having added这个动作

应该是company发出的，但是主句的主语却是sales，所以动作发出者有问题
E：add动作发出者不是sales

请看这个句子是不是run on错误？and 后面的it就是Erie Canal ，所以it应该省略吧？
