We use “some” in three specific situations: 1)In positive affirmative sentences with countable nouns in the plural and with uncountable nouns. Example “There are some apples” and “there is some rice.” 2)In questions asking to receive something for example: “Can I have some apples?” or “Can I have some rice?” 3)We use “some” in questions offering something to someone like “Would you like some apples?” We use the word “any” in two situations: 1) In normal questions for countable plural nouns and uncountable nouns, like for example “Do you have any apples?” and “Do you have any rice?” 2) We can also use “any” in negative statements: “I don’t want any apples” and “I don’t have any rice.”

FORM

In a Type 2 conditional sentence, the tense in the ‘if’ clause is the simple past, and the tense in the main clause is the present conditional or the present continuous conditional.

As in all conditional sentences, the order of the clauses is not fixed. You may have to rearrange the pronouns and adjust punctuation when you change the order of the clauses, but the meaning is identical.

FUNCTION

The type 2 conditional refers to an unlikely or hypothetical condition and its probable result. These sentences are not based on the actual situation. In type 2 conditional sentences, the time is now or any time and the situation is hypothetical.

It is correct, and very common, to say “if I were” instead of “if I was” (subjunctive mood).

In type 2 conditional sentences, you can also use modals in the main clause instead of “would” to express the degree of certainty, permission, or a recommendation about the outcome.

THE PRESENT CONDITIONAL TENSE

The present conditional of any verb is composed of two elements:
would + the infinitive of the main verb, without “to”
