There are several types of conditional statements in English, which are used to express a hypothetical situation and its consequences.

1. The zero conditional is used to describe a factual or general truth. It is formed with the present tense in both clauses.

Examples:

• If you heat ice, it melts.
• If you add salt to water, it boils at a higher temperature.
1. The first conditional is used to describe a possible future event and its probable consequence. It is formed with the present tense in the conditional clause and the future tense in the consequence clause.

Examples:

• If it rains tomorrow, we will stay inside.
• If you study hard, you will pass the exam.
1. The second conditional is used to describe an imaginary or unlikely situation and its consequence. It is formed with the past tense in the conditional clause and the would + infinitive form in the consequence clause.

Examples:

• If I won the lottery, I would buy a house.
• If I were you, I would apologize.
1. The third conditional is used to describe a past event that did not happen and its hypothetical result. It is formed with the past perfect tense in the conditional clause and the would + have + past participle form in the consequence clause.

Examples:

• If he had studied harder, he would have passed the exam.
• If she had left earlier, she would have avoided the traffic.

It’s important to note that the consequence clause in all types of conditionals is not a real consequence, but a hypothetical one.
