Conditional sentences type 0Conditional sentences type 0 describes an action, events always right, type a truth.The structure-the formula conditional sentences type 0: If + S + V, S + VFor example, If you heat ice, Arctic melts it-if we heat the stones, it will melt.2. Conditional sentences type IConditional sentences type I is also known as conditional sentences in the present.We use conditional sentences type I to set up a condition that can be implemented in the present and the stated results can occur.Structures-recipe-form conditional sentences type I: If + S + V, S + will + VIn other words, in conditional sentences type 1, clause IF using present simple, the main clauses used simple future tense.For example:If you come into my garden, my dog will bite you. (If I step into my garden, my dog will bite him.)If it is sunny, I will go fishing. (If the Sun sunshine good, I'll go fishing.)3.

P-from two), S + would + have + V (P. P-from two) In conditional sentences type III, the verb of the clause if divided in the past participle, also of the main clause verbs divided into in complete condition (conditional perfect).
