The Subjunctive Mood is used <em>express possibilities, not facts</em>. This form of verb is used after some expressions that contain wish, a hypothetical, an order or request. Example: <em>They demanded that he </em><em>apologize</em>.<em> I suggested</em> <em>that she </em><em>see</em><em> a doctor</em>. These sentences generally stress importance. The <em>present subjunctive</em> has exactly the same form as the infinitive (to be is be <em>for</em> <em>all persons</em>.)
