我听学姐说过，如果到规定时间还没交三方协议的话，老师会在论文上卡你，让你通不过论文答辩。
wǒ tīng xuéjiě shuō guo ，rúguǒ dào guīdìng shíjiān hái méi jiāo sānfāngxiéyì dehuà ，lǎoshī huì zài lùnwén shàng qiǎ nǐ ，ràng nǐ tōngbuguò lùnwén dábiàn 。
I heard my classmate say that if you don't hand in the three party employment agreement before the stipulated time, teachers will block your thesis and not allow you to get past your thesis defense.
