Conditional sentences with mixed time frames are those sentences in which the second conditional uses the simple past in the if clause and would have and a verb in past participle in the result clause for example:
If I weren´t a teacher, I would have been rejected.
I´m a teacher. I was not rejected.
This example shows how a situation in the present affects another situation in the past.
Thesecond contitional normally uses simple past and would plus a verb, but this does not occur in mixed time frames.
The third conditional in mixed time frame uses past perfect in the if clause and would plus base form of the verb in the result clause to show how a situation from the past affects another situation in the present for example:
If I hadn´t eaten so much, my jeans would fit now.
Iate a lot. My jeans don´t fit now.

Oraciones condicionales con plazos mixtas aquellas frases en las que el segundo condicional utiliza el pasado simple en la cláusula si y tienen que y un verbo en participio pasado en la cláusula de resultado, por ejemplo: 
Si yo no fuera un maestro, yo habría sido rechazada . 
soy un maestro. No fue rechazada. 
Este ejemplo muestra cómouna situación en la actualidad afecta a otra situación en el pasado. 
El segundo contitional normalmente utiliza el pasado simple y sería más un verbo , pero esto no ocurre en los marcos de tiempo desiguales.

Si yo no hubiese comido tanto, mis pantalones vaqueros cabría ahora. 
comí mucho. Mis jeans no se ajustan ahora.

MIXED CONDITIONAL SENTENCES
It is possible for the two parts of a conditional sentence to refer to different times, and the resulting sentence is a “mixed conditional” sentence. There are two types of mixedconditional sentence:
A. Present result of past condition:
1. Form
The tense in the ‘if’ clause is the past perfect, and the tense in the main clause is the present conditional:
‘IF’ CLAUSE | MAIN CLAUSE |
If + past perfect
If I had worked harder at school
If we had looked at the map | Present conditional
I would have a better job now.
we wouldn’t be lost. |
2. Function
In these sentences,the time is past in the ‘if’ clause, and present in the main clause. They refer to an unreal past condition and its probable result in the present. They express a situation which is contrary to reality both in the past and in the present:
‘If I had worked harder at school’ is contrary to past fact – I didn’t work hard at school, and ‘I would have a better job now’ is contrary to present fact – Ihaven’t got a good job.
If we had looked at the map (we didn’t), we wouldn’t be lost (we are lost).
Examples:
* I would be a millionaire now if I had taken that job.
* If you’d caught that plane you’d be dead now.
* If you hadn’t spent all your money on CDs, you wouldn’t be broke.
B. Past result of present or continuing condition.
1. Form
The tense in the If-clause is the simplepast, and the tense in the main clause is the perfect conditional:
‘IF’ CLAUSE | MAIN CLAUSE |
If + simple past
If I wasn’t afraid of spiders
If we didn’t trust him | Perfect conditional
I would have picked it up.
we would have sacked him months ago. |
2. Function
In these sentences the time in the If-clause is now or always, and the time in the main clause is before now. They refer toan unreal present situation and its probable (but unreal) past result:
* ‘If I wasn’t afraid of spiders’ is contrary to present reality – I am afraid of spiders, and ‘I would have picked it up’ is contrary to past reality – I didn’t pick it up.
* ‘If we didn’t trust him’ is contrary to present reality – we do trust him, and ‘we would have sacked him’ is contrary to past reality –...
