(A)

(B)

(C)

(D)

(E)

答案是C，我的问题是：Iguana s have been an important food source in Latin
America since prehistoric times and it is still prized as a game animal by the campesinos, who typically cook the meat in a
heavily spiced stew.

如我改后的句子，先不考虑此句语法、逻辑错误；但说这种句子结构对不对？算不算run-on?and到底可否连接两个并列的句子？

谢谢！

用it是不对的，因为前面是Iguanas是复数，it没有指代物。

OG中有很明确的解释。**and连接句子前面一定要都逗号隔开。

and连接parts of sentences前面是否需要逗号呢？答案是：不一定！

examples:
Theoretically, this convection would carry the continental plates along as though they were on a conveyor belt and would provide the forces needed to produce the split that occurs along the ridge.
and 连接两个句子，主语一致省略，但前面并没有用逗号隔开！
The enclosed seas are an important feature of the earth’s surface, and seriously require explanation because, in addition to the enclosed seas that are developing at present behind island arcs, there are a number of older ones of possibly similar origin, such as the Gulf of Mexico, the Black Sea, and perhaps the North Sea.
and 连接两个句子，主语一致省略，但前面用逗号隔开了！

 

so...

Iguana s have been an important food source in Latin America since prehistoric times and it is still prized as a game animal by the campesinos, who typically cook the meat in a heavily spiced stew.

can be changed like this:

Iguana s have been an important food source in Latin America since prehistoric times and are still prized as a game animal....

run-on的句子:

1.主语相同,用and连接无逗号即:A do X and A do Y

2,主语不同,用and连接无逗号即:A do X and B do Y

正确句子:

1.主语相同: A do X and do Y

2,主语不同：A do X；B do Y 或 A do X，and B do Y

再次看到这题,又有一点想法:

1.主语相同时重复主语(或用代词指代)或多套主谓,且没有",and"肯定是run-on,

2.但如果有",and",第2个主语用代词指代则不属于run-on.

根据楼上ＭＭ总结也就是

run-on:A do X and A do Y

       A do X and B do Y

对的句子：　A do X , and A do Y(这个ＭＭ的意思是只能用代词代替Ａ才有效　而直接重复主语还是算错吗？？？）

            A do X , and B do Y

           A do X; B do Y 

 哪位ＮＮ都解答一下呢？？谢谢！！！
