Conditional Sentences These sentences are sometimes called if-clauses. The conditional tense says that an action is reliant on something else. The two most common conditionals are real and unreal.

Слайд 3

The real conditional (often named 1st Conditional or Conditional Type I) describes situations based on fact. The unreal conditional (often named 2nd Conditional or Conditional Type II) describes unreal or imaginary situations. There is also what we call the 3rd conditional (often named Conditional Type III), used to express no possibility of something having happened in the past, and the 0 conditional (often called the zero conditional),used to express absolute certainty.

1st Conditional / Conditional Type I The first conditional is used to express situations based on fact in the present or future (things which may happen). (IF Clause) (Main Clause) Present Simple Future If I see you tomorrow, I will buy you a drink. or… (Main Clause) (IF Clause) I will buy you a drink if I see you tomorrow .

For example: If I have time today, I will phone my friend . = I will phone my friend if I have time today. (It is possible that I will have time - therefore the condition is real). If I go to England, I will buy some Cheddar cheese . = I will buy some Cheddar cheese, if I go to England. (It is possible that I will go to England - therefore the condition is real). Note ! We never use will , or won't in the if clause

Слайд 7

(IF Clause) (Main Clause) Past Simple Conditional If I won the lottery, I would buy a new house. or... (Main Clause) (IF Clause) I would buy a new house if I won the lottery.

For example: If I were you, I wouldn't do that. = I wouldn't do that, if I were you. (I am not you - therefore the condition is unreal) If I had more time, I would do more on my websites. = I would do more on my websites, if I had more time. (I don't have more time - therefore the condition is unreal). Note! We never use would , or wouldn't in the if clause

Слайд 12

Zero Conditional / Conditional 0 The conditional 0 is used to express general truths and facts (often things based on scientific fact). We use the simple present tense. (IF Clause) (Main Clause) If you heat water to 100°C, it boils . or... (Main Clause) (IF Clause) Water boils if you heat it to 100°C . Note ! Most zero conditional sentences mean the same thing if " when " is used instead of " if ".

For example : If you drop an apple, it falls. = An apple falls, if you drop it. (This is an absolute truth based on scientific fact - gravity). If you don't do your homework, I will be disappointed . = I will be disappointed, if you don't do your homework. (This is a general truth based on previous knowledge - you know that I am disappointed if people don't do their homework).
