Soru: Complete the sentence with the correct form of the verb in parentheses: "If I ______ (have) more time, I ______ (visit) my grandparents last weekend."
Çözüm: This is a third conditional sentence about an unreal past situation. The structure is: If + past perfect, would have + past participle. First, identify the verb "have" needs to be in past perfect form: "had had" (but we usually say "had" for simplicity). Second, "visit" needs to be in "would have visited" form. So, the complete sentence is: "If I had had more time, I would have visited my grandparents last weekend." We use this to talk about something that didn't happen in the past.
