　　请问这句话有什么语法错误?顺便改正.

　　Hewastheonewhoalwayschattedinclass,procrastinatedhishomeworkandalmostflunkedeveryexam.

　　Microsoft-Word说procrastinated是verbconfusion.butIdon'tknowwhy.

　　1.To“tingting_175”，首先，thankyouforpainstakinglyansweringmyquestion.

　　BUT

　　procrastinated与chatted和flunked并列，一起充当从句的谓语应该是可以的吧。

　　2.merriam-webster对procrastinate的解释是“transitivesenses:toputoffintentionallyandhabitually”
