高三英语单选的问题

Question

Having a talk with the student, I believe, and you will find Tom is very outgoing.
这话哪儿错了？为什么说主语不一致？

Answer 1

两个逗号之间的语句你可以把它当成插入语，那么就成了Having a talk with the student and you will find Tom is very outgoing.这是个错句型。我们学过的是“祈使句加由and引导的并列句，并列句用一般将来时。”把having改成原型have 就对了。

Answer 2

应该删去and you wil……中的and
因为“I believe”为插入语，不影响句子结构，删去插入语来看是非谓语结构：
Having a talk with the student,you wil find Tom is very outgoing.
而and是连词，连接两个句子的，应该删去。

Answer 3

这句话主语是I，而have a talk 的主语是you，所以说主语不一致。
可以把and去掉，这样I believe 就变成插入语，不做成分，句子就可以写成Having a talk with the student, you will find Tom is very outgoing. 逗号前为非谓语动词做状语，且逗号后面具备完整的句子成分。
