Hello! I am a teacher of English from school N 1253 and in this video I’m going to explain Conditionals to you. If you mix vinegar and baking soda you get some gas, carbon dioxide. Look! It’s a fact from chemistry but grammatically it’s a conditional sentence.
Conditionals start with IF and consist of 2 parts. In the first part we have a condition. In the second part we have a result. IF you DO this, you GET that.
The main problem with Conditionals is how to use tenses correctly. I have invented a simple scheme which will help you organize it in your mind.
All the conditionals can be divided into 2 big groups. Real and Unreal. Real are about facts and possibilities. Unreal are about dreams and imaginary events.
This is my scheme for the real Conditionals. It’s where the sentence starts. This circle stands for the first part – a condition, this green circle is for a comma. And this is for the result. The clock hand symbolises how the sentence goes – from “If” to the full stop.
In real Conditionals we can only use a Present Tense after “IF”. If it’s a fact – we use Present once again. If it’s a real possibility in the future, we need Future Simple after the comma. For example: “If you mix soda and vinegar, you get carbon dioxide. IF you learn this trick, you will surprise your friends.”
This is The Persistence of Memory by Salvador Dali. Dali got the idea for the picture when his breakfast cheese melted under the sun. There are melted pocket watches and an eye of a dreamer in the picture. Probably Dali wanted to say that when you dream or imagine something, time goes differently.
What’s interesting, in English when we talk about imaginary events, we only use past Tense forms. If the condition is in the Imaginary Present, we use Past Simple. If it’s in the past, we need Past Perfect. If the result is in the Present or Future, we use Would + infinitive. If it’s in the Past, we take Would have and Past Participle.
For example: If Dali hadn’t eaten cheese for breakfast, he wouldn’t have painted the Persisnance of Memory. If we didn’t have this picture by Dali, there wouldn’t be numerous posters and souvenirs with melted watches now.
We can also mix these tenses as we need. If Dali hadn’t eaten cheese for breakfast, there wouldn’t be numerous posters with melted watches.
All you have to memorise now is a couple of diagrams.
