Zero Conditional - Grammar Notes

Point 1: The zero conditional shows a simple cause and affect. Action A causes Action B.
  1. Turn on the heater if it gets hot.
  2. I do not walk if it rains.
  3. I take the bus if I have time.
  4. I do not drive if the traffic is bad.
Point 2: The zero conditional uses when instead of if in some cases.
  1. I do not walk to work if it rains.
  2. I do not walk to work when it rains.
  3. I take the bus if I have time.
  4. I take the bus when I have time.
Point 3: Because zero conditionals are subordinating clauses, the order of the clauses can be reversed.
  1. He gets mood if he does not have coffee.
  2. If he does not have coffee, he gets moody.
  3. The beach is crowded if the weather is nice.
  4. If the weather is nice, the beach is crowded.
Point 4: The zero conditional uses the simple present tense because it expresses recurring actions.
  1. We play cards of the weekend if we feel like it.
  2. If she gets stressed, she starts acting strange.
  3. If the economy is good, people spend more money.
  4. When it rains, it pours. (idiom)
