think 后面可以接if引导的从句吗？

问题描述

下面这个句子出自2012年的一道高考题（安徽省考题），这里think后面怎么接了if引导的从句呢？

Grace doesn’t want to move to New York because she thinks if she were to live there, she wouldn’t be able to see her parents very often.

请问：think if…与think that…有何区别？

老师答疑

张老师：

换句话说，就是从句里面套从句。不过把if she were to live there, she wouldn’t be able to see her parents very often. 看做I think的宾语从句也未尝不可，只不过这个宾从又是有一个复合句构成，从句为条件句，主句为最后一句。

罗老师：

Grace doesn’t want to move to New York because (she thinks) if she were to live there, she wouldn’t be able to see her parents very often.

because引导原因状语从句，she thinks是插入语，去掉插入语，这个句子结构就更清晰了，if she were to live there是原因状语从句中的一个虚拟条件句。并非您所说的think后面接if还是接that区别的问题。
