Romeo tells Gary he will only travel with him if they go in a car. He says, “If you were willing to drive, we could do that.” He uses the second conditional.
We use the second conditional (also sometimes called the “present unreal conditional”) to talk about a situation that is not real or is unlikely to happen and what might happen as a result.
For example, I might say, “If I had a million dollars, I would go on a trip around the world.” I don’t have a million dollars. That situation is unreal. But if I did have a million dollars, an around-the-world trip might happen.
The second conditional is formed with two clauses. The first clause consists of if + subject + past tense verb, as in “If I loved him…” The second clause is formed with “subject + would + verb, as in ”…I would marry him.” All together, the sentence looks like this: “If I loved him, I would marry him.”
