Una unreal conditional clause es normalmente comenzada con if pero cuando haces preguntas existen otras alternativas.
Como sabemos ya, una condicional se estructura en:
Conditional clause + Main clause
Conditional clause
If past simple
Imagine (that) past continuous
Supposing (that) subject were to + infinitive
Suppose (that) might
Assuming (that) past perfect
Main clause
would infinitive
(question word) could be + present participle?
might have + past participle
Ejemplos:
Imagine you were meeting someone for the first time, how would
you introduce yourself?
Suppose you didn't enjoy the first date, would you still go on a
second date?
Assuming that you were to go on another date, where might you
be planning to meet?
Supposing that neither of the dates had been successful, what
might you tell the person?
