Answer:
We use Conditional tenses to talk about hypothetic situations in the future, in the past, and to talk about events that would have happened.
a. If we were to be hit by an iceberg, we would die.
b If my cat were to eat a mouse, it would be a predator.
c If I were never to go in the sun, I would be extremely pale.
Explanation:
Conditional tenses communicate hypothetical situations in the past, theories about what might have happened, what happens concerning facts that are always true, and events with a low probability to occur in the future.
The sentences in this exercise are using conditionals to talk about situations in the present or future that probably will not happen.
We use:
the word if + the subject + were to,.... + subject + would + verb in the infinitive....
In formal writing, we can use the subjects he, she, and it with the auxiliary were instead of was and then the verb in the infinitive. For example, If he were to fail his test, he would be sad.
Although it was early the heart already hung heavy in the air.
