“创业的赞成者与反对者”是持不同观点的学生，是主句的主语，从句while at college就是while they are at college的省略。

各位老师好，想请教一下下面这个句子里，无动词分句使用是否正确？

There are pros and cons of starting a business while at college.

按理说无动词分句的主语要跟主句主语一致，但是这个句子里，主句是there be句型，这种情况下可以用无动词分句么？谢谢各位老师。

以上句子主语“省略逻辑主语”的语言现象。

There are pros and cons of (the students省略 )starting a business while (they are 省略)at college

参考译文：在大学期间，学生们创业有利和弊。
