The document discusses the different uses of conditional sentences in English grammar. It provides examples of the three main conditional types: first conditional to discuss possible future events using "if + present, will/won't"; zero conditional to state general truths using "if + present, present"; and second conditional to discuss imaginary present or future situations using "if + past, would". Learners are asked to match example sentences to their corresponding conditional use.

2. If you have children, you worry about them all the time. If I arrive home early, I will cook a nice dinner. If I were rich, I would buy a new house. Work in pairs. Match the sentences with their uses. Use 1: To talk about the result of a possible event or situation in the future. Use 2: To talk about imaginary situations in the present or future.
