# 1. Introduction

Hello dear student and welcome to today English lesson!

In the last lesson, we started a new block learning about Conditionals. We use Conditionals all the time in English, so it is very important that you learn them and feel comfortable using them in your writing and speaking.

There are four types of Conditionals:

- Zero condional
- First condional
- Second condional
- Third condional

Conditional allow us to express things that can happen in the present and future. We use them for real or unreal situations. Take a look at these questions: pay attention to see if the situation is real or unreal. How does the structure change in each question?

What happens If we heat water to 100°?

What will you do if you miss the train?

What would you do if you were the president?

What would you have studied if you hadn’t done social science?

Last session we learned about zero and first conditonals. We also learned that conditional sentences always have two clauses. The "If" clause and the "main clause" (sometimes called the "Result" clause).

In the introductory clip below, I will briefly review the last lesson, give an overview of today's lesson and explain how to work with this website.
