If he had come earlier,		if they had read the book.
The water in the pool would have been warmer		he would have met Tina.
If you had phoned me,		she would have stopped .
They would have understood the film		I would have recorded the show.
If the car had turned left,		the old lady could have crossed the street.
The boys would have won the match		if the sun had shone more often.
If she had noticed the red traffic light,		if they had trained regularly.
