Possible Future Situations

→ If I finish work early, I will go shopping.

Imaginary or Unlikely Situations
Rewrite the sentences using “if”.
Example:
I have more money. I would buy a bigger house.
→ If I had more money, I would buy a bigger house.

For this exercise, understand that the first sentence is an imagined situation, so the verb changes to the
past form.

Past Situations That Cannot Be Changed
For this exercise you need to understand what actually happened in the past before rewriting it.
Example:
I didn't study hard. I didn't pass the exam.
→ If I had studied hard, I would have passed the exam..
Now you can clearly see: this happened → imagine a different past
