CONDITIONALS

CONDITIONALS

1. Objective: Understand and use conditional sentences in real-life and professional contexts.

2. WHAT ARE CONDITIONALS?

   • Conditional sentences describe possible situations and their results.
   • They usually contain two clauses:
   • If-clause: the condition
   • Main clause: the result
   • Example: If you study hard, you will pass the exam.

3. TYPES OF CONDITIONALS

   • Zero Conditional – If + Present Simple → Present Simple → Facts
   • First Conditional – If + Present Simple → will + verb → Real Future
   • Second Conditional – If + Past Simple → would + verb → Unreal Present/Future
   • Third Conditional – If + Past Perfect → would have + past participle → Unreal Past

4. ZERO CONDITIONAL (Facts and Rules)

   • Form: If + Present Simple, Present Simple Used for scientific facts or rules.
   • Examples:
     • Mechatronics: If a sensor fails, the engine stops.
     • Electricity: If current exceeds the limit, the fuse melts.
     • Nursing: If the patient has a fever, the nurse checks temperature.
   • Activity: Write two zero conditional sentences from your field.

5. FIRST CONDITIONAL (Real Future)

   • Form: If + Present Simple, will + verb Used for possible future events.
   • Examples:
     • Mechatronics: If you replace the faulty part, the car will run smoothly.
     • Electricity: If you don’t turn off the power, you will get shocked.
     • Nursing: If the patient follows the treatment, they will recover faster.
   • Activity: Write a short dialogue using first conditional.

6. SECOND CONDITIONAL (Hypothetical Present/Future)

   • Form: If + Past Simple, would + verb Used for imaginary or unlikely situations.
   • Examples:
     • Mechatronics: If I had a diagnostic scanner, I would check the system faster.
     • Electricity: If I worked at a power plant, I would improve energy efficiency.
     • Nursing: If I were the head nurse, I would change the shift schedule.
   • Activity: Write one hypothetical situation from your field.

7. THIRD CONDITIONAL (Imaginary Past)

   • Form: If + Past Perfect, would have + past participle Used for unreal past situations.
   • Examples:
     • Mechatronics: If we had checked the brakes, the accident wouldn’t have happened.
     • Electricity: If I had worn gloves, I wouldn’t have been injured.
     • Nursing: If the patient had taken the medicine, they would have improved.
   • Activity: Share one example of a past situation that could have been avoided.
