There are three types of conditional sentences. But now, I will tell you only types of conditional sentence first.

1. Expressing Possibilities

If + simple Present, S + Will

The pattern above is used when you think about a real possibility in the present and future.

Examples:

¨ If you know the function of these buttons, you will certainly understand how to use them

¨ If I have time, I will learn how to browse on the internet

2. Expressing Imaginary Situation

If + simple Past, S + Would

When what you say is unreal (never happens now nor in the future) you use past tense

Examples:

¨ If I used the internet chat, I would get some e-friends

(It means you don’t use the internet chat)

¨ If I were a rich man, I would build a cozy house

(It means you are not rich)

Note:

Were is used for both singular and plural subjects

Examples:

If Agung were a wise man, he would be a good leader

If you were an artist, you would be a famous person
