113. The original building and loan associations were organized as limited life funds, whose members made monthly payments on their share subscritions, then taking turns drawing on the funds for home mortgages.

A.subscriptions, then taking turns drawing

B.subscriptions, and then taking turns drawing

C.subscriptions and then took turns drawing

D.subscriptions and then took turns, they drew

E.subscriptions and then drew, taking turns

我知道took turns与made平行，所以A,B,E错。请问：

 take turns 后为什么是drawing? take turns doing是固定搭配吗？

谢谢！

C: and then took turns，是一个完整的主谓成分，后面的they drew无论如何是run on

至于你说的那是不是一个短语，既然答案是，那么肯定是的。：）问题是。这个题目的本意不是考短语。

这里为什么用分词taking不好？
