My sister and I ________ in No.7 Middle School.,

There ______ some milk in the cup.

I wonder whether the teacher is one of those who _______ to the mountain village to help the children there.

—Remember that where and when two different English question words___________. —I see, but can you tell us how to use them, sir?

Not only he but also I ______ able to solve this kind of problem.
