刚看到有关大全72，A选项

(A) Aho, a Kiowa matriarch, held festivals in her home, they featured 是一个ETS称为run-on的结构，精简后是Aho held festivals, they featured。2个句子不能这样并列

不太明白，什么是RUN-ON结构呢？

请NN们指点~

不间断句子(run-on sentences)
　　什么叫run-on sentence?请看下面的例句。

　　例1. there are many ways we get to know the outside world.

　　剖析：这个句子包含了两层完整的意思：“there are many ways.”以及“we get to know the outside world.”。简单地把它们连在一起就不妥当了。

　　改为：

　　there are many ways for us to learn about the outside world.或：

　　there are many ways through which we can become acquainted with the outside world

RUN-ON SENTENCES
When a sentence consists of more than one clause, those clauses must be joined properly. It is never acceptableto hook two clauses together with a comma, as the “sentence” below does. That’s called a run-on sentence.
Wrong: Nietzsche moved to Basel in 1869, he planned to teach classical philology.
There are a number of acceptable ways to fix a run-on.
1. Make two separate sentences:
Nietzsche moved to Basel in 1869. He planned to teach classical philology.
2a. Change the comma to a semicolon:
Nietzsche moved to Basel in 1869; he planned to teach classical philology.
2b. Join the clauses with a semicolon and a transition word such as however or therefore.
Nietzsche planned to teach classical philology; therefore, he moved to Basel in 1869.
