NOT A TEACHER
1. Just a gentle reminder that in American English, one always uses a period after "Mr." For example, "Mr. Clinton visited our school."
2. "If he were the president, he would ask Congress to give free ice cream to all of us."
a. The "were" is the subjunctive. He is NOT the president, so traditionally one should use the subjunctive. For example: I am NOT intelligent, but I wish (that) I were intelligent.
b. It seems that the subjunctive is still quite popular in the United States.
3. "If he was the president, he would ...."
a. This is how many people would say that sentence. In other words, they would NOT use the subjunctive. For many people, "was" sounds more "natural." ("I wish I was / were intelligent.")
4. Mr. Clinton was NOT the president in 1950. But if he had been the president, he would have asked the Congress to give us all free ice cream.
