中文原文
早上你在地铁站等车，地铁晚点了。你拿出手机看消息，发现老板发来信息，让你到公司之后先去参加一个临时会议。你有点担心会迟到，开会来不及准备。
My translation
I was waiting at the subway station in the morning. The train was late. I took out my phone to check messages, and found that my boss had asked me to attend an unscheduled meeting after I arrived the company. I was worried about being late and having not enought time to prepare.
Revised version
This morning, I was waiting for the train at the subway station, but it was delayed. I pulled out my phone to check messages and noticed my boss messaged me, asking me to go to an impromptu meeting right after I arrived at the office. I was concerned I’d run late and wouldn’t have time to get ready for it.
