Write a sentence in the subjunctive verb mood (using words that show that something is hoped for, but is unlikely). How can you tell if a sentence is written in the subjunctive mood?

If only he were to show up to the party tonight, we would have such a great time.

A sentence is written in the subjunctive mood if it expresses a desire, a suggestion, a request, a necessity, a doubt, a condition contrary to fact, or a hypothetical situation. The verb form used in the subjunctive mood often differs from the indicative form.
