6. Last Saturday while Sandy (clean) was cleaning out the attic, she found her grandmother's wedding dress.

7. It started to rain while I (drive) was driving to work this morning. I didn't have an umbrella with me. I (get) got very wet when I stepped out of my car.

8. When we looked outside during the storm, we saw that the wind (blow) was blowing very hard, and the trees (bend) were bending over in the wind.

9. When the teacher came into the room, most of the children ( play) were playing together nicely. But over in the corner, Bobby ( pull) was pulling Annie's hair. The teacher quickly ran over and pulled Bobby away from Annie.
