What Would Happen?
Second Conditional
The second, or 'unreal', conditional is used for improbable situations that are purely hypothetical. Use the second conditional when imagining various situations.
'If' clause - past simple + , + result clause - would + verb (conditional tense)
Examples of Unreal Situations
I would respond to the backorder if I were in charge.
She would bring back more on the backhaul if the warehouse staff would help her load.
She would use a laser-guided system if the company could afford it.
She would get through the backlog faster if she had access to the computer system.
Exception!
'Were' is often used for all subjects in the second conditional.
Example:
I would use the bandsaw if I were trained to use it properly.
I would apply for the position if I weren't concerned about the learning curve.
Differences Between First and Second Conditional
The choice between the first or second conditional is often based on the probability of a given situation. If something is truly possible, choose the first conditional.
Example:
They won't produce the product with the proper dimensions, if we don't get them the information they need.
We'll switch to a direct ship model if we find an online retailer who can provide us with buyers.
If something is not very possible or improbable, choose the second conditional.
Example:
She would bring back more on the backhaul if the warehouse staff would help her load.
He would use the lathe on the metal if it weren't jammed.
Do not use a comma, when placing the result clause first.
He would use the lathe on the metal if it weren't jammed.
She would get through the backlog faster if she had access to the computer system.
