崔西，你教哪个年级？

What grade do you teach, Tracy?

你现在在哪个年级？

Which grade are you in now?

您教哪个年级? 教哪一门数学课?。

Which grade(s) do you teach? Which math subjects do you teach?

业主手册是你最好的指示器在哪个年级的使用。

The owner's manual is your best indicator on which grade to use.

但是，我想无论你有多大、在读哪个年级，许多人都打心底里期望此刻还在放暑假，以及这天不用那么早起床。

I imagine there are some seniors out there who are feeling pretty good right now -- (applause) -- with just one more year to go.
