找到 TA,面对面的说:
I appreciate your trust when you needed a hand lately. I hope I was able to help.
I have trouble during the past a few days because I could not tie my labor hours to the tasks from you so I am getting concerned in my performance in the view of my (or our?) supervisor.
May I ask you please to pass work through my (or our?) supervisor so that TA knows how to match my work to payroll hours?
I simply don't want to get myself into troubles and I hope you can understand. If you have urgent things and you need my assistance, I will be more than happy to do so after work.
