Complete the clumsy spy's urgent message to headquarters by dragging the right verb forms into the gaps.

Boss, I have lost the top-secret gadget! I am so sorry. I left it on the subway this morning while I was eating a bagel.

Boss, I have lost the top-secret gadget!

We use the Present Perfect (have lost) to announce recent news or an action that has a direct result in the present (the gadget is still missing).

I left it on the subway this morning while I was eating a bagel.

Once we introduce the general news, we switch to the Past Simple (left) to give specific details about when, where, or how it happened.
