Unreal conditional clauses - alternatives to if

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?
