Dr Jackson ...... (hide) his research results last month. Honestly, I have no clue why he did it.

The singer ...... (make) an awful performance last Saturday. Something must have been wrong.

The heavyweight boxing champion ...... (crack) some cheesy jokes tonight. I wonder what's wrong with him.

The local hunters ...... (kill) the poor deer last night. They say it was too sick to be nursed to good health again.

The rocket engineer ...... (draw) a new series of plans for the engine. He keeps changing his mind all the time, really.

Monica ...... (lose) my ID card on her way home. Now I've got to get a new one, damn.

Martin ...... (talk) back to his teacher in the morning. That's why he's got to see the headmistress now.

You ...... (give) away our secret, Matthew. I wish you hadn't done so.

The commander ...... (embezzle) funds last month. Honestly, I've got no idea why he did such a stupid thing.

Joe ...... (argue) about last Monday for hours. Still, he didn't persuade the boss to give him an extra day off.

The skydiver ...... (jump) off the plane and open his parachute right away!

The astronauts ...... (send) us some blurred pictures, but nothing else, Dr Handerson.
