请问这句话有什么语法错误?顺便改正.
He was the one who always chatted in class,procrastinated his homework and almost flunked every exam.
Microsoft-Word说procrastinated是verb confusion.but I don't know why.
1.To“tingting_175”，首先，thank you for painstakingly answering my question.
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“transitive senses:to put off intentionally and habitually”
