Answer:
a) Lea will go to NUST next year if she meets the requirements. First conditional.
b) If you freeze water, it becomes solid. Zero conditional.
c) If I get $1 million in my life, I will marry the most beautiful woman in the universe. First conditional.
d) Had I studied this course ten years ago, I would have become a lecturer. Third conditional.
e) If I hadn't withdrawn from the gang, I would also be in prison now. Second Conditional
Step-by-step explanation:
There are four types of conditionals, each of them expresses different situations.
- Zero conditional: we use it to talk about things that are always true. like sentence B, "If you freeze water, it becomes solid." To use the zero conditional, we use the If + clause in present simple,+ clause in present simple.
- First conditional: we use it to talk about things that may happen in the future or hypothetical situations. Sentence A, "Lea will go to NUST next year if she meets the requirements." uses the first conditional to talk about an event that is likely to happen in the future. Sentence c, "If I get $1 million in my life, I will marry the most beautiful woman in the universe." use this conditional to talk about a hypothetical situation. To write a sentence, we first use the If + clause in the present simple,+ will + clause with the verb in the infinitive. Also, we can write the if + clause at the end. In this case, we do not add a comma after the will + infinitive.
- Second conditional: we use this conditional to talk about an imaginary or hypothetical situation in the present or future. It is present in sentence E "If I hadn't withdrawn from the gang, I would also be in prison now.". To use it, we have to write the if + clause in past simple, + would + clause in the infinitive.
- Third conditional: we use this conditional to talk about something that we wish we had done in the past and its hypothetical outcome. It is present in sentence D "Had I studied this course ten years ago, I would have become a lecturer." We can see that the person is expressing a hypothetical situation in the past and how things would be. To use the third conditional, we write the if + clause in the past perfect, + would have + clause in the infinitive. In sentence D, instead of using if, there is an inversion of the auxiliary and the subject.
