In which conditional sentences can we use the link-word “when” instead of “if”.Say why.
a) If water gets into the mechanism , it stops.
b) If she didn’t work well, they would not trust her.
c) If you take the bus, you will save time and money.
- If water gets into the mechanism, it stops.
Sentence “a” is in type 0, the situation is a general truth and its result is a 100% certain.
So we can also say:
When water gets into the mechanism, it stops.
c)When you take the bus, you will save time and money.
Sentence “c” is in type 1, the situation that will probably happen if a given action happens. We use “when” to say that this action will lead to a certain result and we use “if” to say that the result is probable or possible.
