For the Present Subjunctive, we use the Past Simple and say, "If I took; if I opened" etc., whilst for the Past Subjunctive, we use the Past Perfect and say, "If I had taken; If I had opened" etc. SENTENCE STRUCTURE: -I've just got home at 6:45pm. -My cat is in my room. -An open conditional expresses a probability. -Its construction is "If + present + future". -If I am hungry, I will eat something. -A Present Subjunctive conditional expresses a supposition in the present; something that, in fact, does not happen. -Its construction is: "If + Past + Conditional'' -If I worked hard, I would be tired.
