My friend, Jack, will have a holiday as soon as he ________ his work next week.

There _______a class meeting this afternoon?

Not only Jim but also his parents ______ a few places of interest since they came to China.

—Hey, Jack. You ________ on the phone just now. But you weren’t here and the man left a phone number. —Oh? I was in the library.

When the teacher ______ how to do the experiment, the bell rang.
