ESL/EFL Worksheets for Conditional Forms Here is a quick review of the first and second conditional forms. Both first and second conditionals  are used to imagine situations in the present or future. In general, the first conditional, or real conditional is used to express what will happen if a certain event takes place in the present or future. It is called the real conditional because it refers to situations which are truly possible. First/Real Conditional If Subject Present Simple (positive or negative) Objects, Subject Future with Will (positive or negative) Objects Examples: If he finishes the work on time, we will play a round of golf this afternoon.If the meeting is successful, we will become partners with Smith and Co. Unless can be used in the first conditional to mean if not. Examples: Unless he hurries up, we will be late.Unless it rains, we wont get wet. The if clause can also be placed at the end of the sentence. In this case, no comma is required. Examples: They will be very happy if he passes the exam.Jane will marry Tom if he asks her tonight. Second/Unreal Conditional The second  or unreal conditional is used to speculate about things that are impossible or improbable. If Subject Past Simple (positive or negative) Objects, Subject Would Verb (positive or negative) Objects Examples: If he won the lottery, he would buy a new home.If they were happy, theyd have more fun. Were is used for all subjects. Some universities such as Cambridge University also accept was as being correct. Others expect were for all subjects. Examples: If I were you, Id buy a new car.If she were American, she could remain in the country. The if clause can also be placed at the end of the sentence. In this case, no comma is required. Examples: They would be rich if he were to invent a new type of battery.Angela would be proud of her son got straight As at school.
