Grammar explanation
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.
Zero conditional
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.
First conditional
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.
Second conditional
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.

Hello mary.j,
I think the reason the present is more natural in this sentence is because of the verb 'want'. Since 'want' speaks about an emotional state, which we general speak about from experience (i.e. we already feel the emotion), then it's more natural to use the present. It's not impossible to use 'want' in a future form to speak about a future emotion, but I think we generally use present here.
With verbs that are more actions than emotional, both present and future forms could generally work with 'unless'.
All the best,

Tanks dear Kirk Moore.
Hello,
I would ask you about the second conditional.
It is written:" The second conditional is used to imagine present or future situations that are impossible or unlikely in reality".
Regarding future situations that are possible or impossible, unlikely or likely in reality; future situations that can happen as not to happen, possible or not possible facts:
Can I use the form of the conditional second in the "if" clause?
E.g.
If the weather made things change...
Otherwise, what is the correct form in the if clause?
Thanks for help.
Hello User_1,
The so-called second conditional is not a verb form but a sentence pattern with two clauses: if + past > (then) would + verb.
As you can see, the form used in the if-clause is past tense. This may be past simple or past continuous, depending on the context. Thus, your example has the correct form, though it's not easy to think of a context where the sentence would be useful. Perhaps something like this:

Hello Peter,
Yes, Peter. Thanks for your explanation.
I know the sentence pattern of the second conditional, but in my case the context would be a wish... something like that:
"If the weather made things change, I hope you will remember..."
Could that be correct?
Thank you
Hello again User_1,
I see. In that case the answer is no. Generally, 'hope' implies a possible rather than a hypothetical situation so we would use 'will':
If the weather makes things change, I hope you'll remember...
I think the first part is rather awkward, incidentally. A more natural phrasing would be something like 'If the weather changes/improves)...' or 'If your plans change because of the weather...'

Hello again Peter,
sorry for asking more about it.
I would refer to a hypothetical context, so I will not use "hope".
Could you suggest me a form of wish in a hypothetical context that does not depend on will?
Thanks a lot!
Hello again User_1,
'Wish' is used for present or past counter-factual situations (I wish I were taller / I wish I hadn't taken the job), not for future events, however likely or unlikely. I think you're trying to fit 'wish' into a place that it just cannot go, I'm afraid.

Hello Peter,
I got it. Thanks a lot for your help!
Dear teachers,
Could you please tell me and explain me (giving me some grammar book references) if the following sentence is a zero ou first conditional: "If the child makes a request, such as asking for food, the caregiver may reward the child by providing it"?
Thanks in advance for your help and attention!
