Unit 8 - Life-Changing Decisions

Revision of Conditional Types

Compare all conditional structures to choose the one that communicates your meaning precisely.


1. Zero to Second Conditional – Quick Refresh

  • Zero: If you heat water, it boils.
  • First: If it rains, we will stay at home.
  • Second: If I had money, I would buy a car.

These B1 examples anchor the basic patterns. At B2 we add nuance and Type 3.


2. Summary Table

SecondIf + Past Simple, would/could + V1Unreal present/futureIf she studied harder, she would pass.
ThirdIf + Past Perfect, would/could/might + have + V3Unreal past (regret)If they had left earlier, they would have caught the train.

3. Mixed Conditionals

  • Present result of a past condition

    • If he had listened to the advice, he would be more confident now.
  • Past result of a present condition

    • If I were more organised, I wouldn’t have missed the deadline.

Use mixed forms to connect different time frames.


4. Advanced Connectors

  • As long as / provided that / on condition that
    Provided that you send the data today, we will finalise the report.

  • Even if / whether or not
    Even if it snowed in summer, people would be surprised.

  • In case / in the event that
    Take an umbrella in case it rains later.


5. Common Challenges

IssueTipExample
Verb form mix-upsKeep the if-clause tense consistent with the type.✅ If you had arrived, you would have seen it.
Overusing willOnly the result clause takes will in Type 1.✅ If she calls, I will answer.
Forgetting contractionsMake speech natural with I'd, we'd, they'd.I'd help if I had time.

6. Practice Tasks

  1. Convert real events into each conditional type.
  2. Write two mixed conditionals about your life now.
  3. Re-work simple sentences using advanced connectors like provided that or even if.
