Choose the correct verb form to complete the sentence. Remember: The progressive aspect expresses an unfinished action and/ or an action that is temporary. The perfect aspect expresses a connection between two time periods and can convey that one action or event took place before another. For an action completed at one time or within a period of time, choose the simple present, the simple past, or the future with WILL or BE GOING TO.
