John and I have worked on our games so much.

She had worked on the report but was not getting very far.

We set out in the morning and came back at night, working hard on the way.

I can always work on the other one after they are gone.

She is just about the only one who doesn't work on programs.

The school is working on another performance for the 2013 show.

He was working on something big but wouldn't say what.

He is now working on a history of the state's public schools.

In a way I am already working on the case.

The three worked on the project from 1934 to 1936.
