Unreal past structures
Use past forms after would rather, it is time and as if to express preference, criticism or unreality.
When do we use it?
Distinguish present unreal past forms from past-perfect reference.
Form
Use would rather + subject + past, it’s time + past, and as if + past/past perfect.
- I’d rather you stayed.
- It’s time we left.
- He talks as if he knew everything.
Key contrast
At C1, grammar choices shape emphasis, stance, information flow and register as well as basic correctness.
Common mistakes
I’d rather you stay yesterday.→ I’d rather you had stayed yesterday.It’s time we leave.→ It’s time we left.
Remember
Use past forms after would rather, it is time and as if to express preference, criticism or unreality.
Quick check
- Identify the focus, stance or relationship between clauses.
- Check inversion, complementation and reference carefully.
- Prefer the option that is both grammatical and appropriate for the register.
