Present Perfect Practice
For each sentence below, insert the appropriate form of the present perfect according to the verb indicated in parentheses.
You should type your answer in the uppermost box, then hit the TAB key. As soon as your cursor
leaves an answer box, the correct answer will appear in the box immediately below it. The asterisk erases both answers
to allow you to try again. To produce an accented letter, hold down the ALT key while you type in the
appropriate ASCII code from the list in the status bar at the bottom of your screen. ¡Buena Suerte!
