Conditionals describe the result of a certain condition. The if clause tells you the condition (If you study hard) and the main clause tells you the result (you will pass your exams). The order of the clauses does not change the meaning.
If you study hard, you will pass your exams.
You will pass your exams if you study hard.
Conditional sentences are often divided into different types.
We use the zero conditional to talk about things that are generally true, especially for laws and rules.
If I drink too much coffee, I can't sleep at night.
Ice melts if you heat it.
When the sun goes down, it gets dark.
The structure is: if/when + present simple >> present simple.
We use the first conditional when we talk about future situations we believe are real or possible.
If it doesn't rain tomorrow, we'll go to the beach.
Arsenal will be top of the league if they win.
When I finish work, I'll call you.
In first conditional sentences, the structure is usually: if/when + present simple >> will + infinitive.
It is also common to use this structure with unless, as long as, as soon as or in case instead of if.
I'll leave as soon as the babysitter arrives.
I don't want to stay in London unless I get a well-paid job.
I'll give you a key in case I'm not at home.
You can go to the party, as long as you're back by midnight.
The second conditional is used to imagine present or future situations that are impossible or unlikely in reality.
If we had a garden, we could have a cat.
If I won a lot of money, I'd buy a big house in the country.
I wouldn't worry if I were you.
The structure is usually: if + past simple >> + would + infinitive.
When if is followed by the verb be, it is grammatically correct to say if I were, if he were, if she were and if it were. However, it is also common to hear these structures with was, especially in the he/she form.
If I were you, I wouldn't mention it.
If she was prime minister, she would invest more money in schools.
He would travel more if he was younger.

I Have a question, what's the difference between:
I could have sat in the garden if it had not rained.
I would not have sat in the garden if it had rained.
I would not have been sitting in the garden if it had rained.
I would not sit in the garden when it rained.
I would not be sitting in the garden if it rained.
1, 2 and 3 are all third conditional sentences, which are explained on our Conditionals: third and mixed page. The phrase 'if it had (not) rained' refers to an imaginary past time, in other words, something that did not really happen -- it's just something we imagine.
The phrase 'when it rained' in 4 refers to the past. It is not a conditional. 'would' describes a habitual or repeated past action in this case. Another way of saying this is 'When it rained, I didn't sit in the garden' (referring to a past time in your life).
5 is a second conditional. It refers to an imaginary present or future time when it's raining and you are not in the garden. It could be used when you are sitting in the garden and it is not raining.
Hope this helps you make sense of these.
All the best,
Yes, It really help me a lot.
I have a question about 2nd conditional: in writing, in if clause, tobe -> were for all subjects? Included all pronouns and other subjects?
Ex: 1/ if the weather were good….
2/ if the weather was good …
Which one is correct in writing?
Neither is incorrect. I would say that 'were' is a little more traditional and so can be considered more 'correct' in formal contexts. In less formal contexts both are used. It's really more a question of formality and the attitudes of the people communicating than one of writing vs speaking.

Hello support team
I hope you are doing well.
Which of the sentences below is grammatically correct?
She seems as if she had seen a ghost.
She seems as if she saw a ghost.
Thanks! Hope you are doing fine as well.
Sentence 1 uses the past perfect ("had seen"), which should be used when the action happened before another past event. Sentence 1 does not mention any other past event, so there is no reason to use the past perfect and it is incorrect. However, "She seemed as if she had seen a ghost" is correct.
Sentence 2 is fine. However, the speaker's use of the present simple ("seems") shows that the action ("saw a ghost") probably happened just moments ago, it would be good to use the present perfect ("She seems as if she's seen a ghost"). Using the past simple ("saw") refers to a defined past moment or time, but if the event has only just happened then the present perfect would be preferred.
I hope that helps.
"Don't talk to me as if I were a child".
Please help me to understand is it "a mixture of the first and second type of conditional sentences" or "the verbal construction "as if" requires only the past tense after itself", or something else?
If a mixture of the first and second types of conditional sentences exists, then please send me a link to the material where this is clearly described
The structure here is an imperative followed by 'as if' plus a clause. 'as if' is being used to speak of an imaginary situation and so we use a past form to show that it is imaginary.
Hope that makes sense.
All the best,
Thank you very much!
