Условни изречения: първи и втори тип (Conditionals 1 and 2)
Урокът обяснява първи и втори тип условни изречения. Първият тип (If + Present Simple, will + глагол) е за реални и възможни ситуации в бъдещето. Вторият тип (If + Past Simple, would + глагол) е за нереални или малко вероятни ситуации в настоящето или бъдещето. Учениците учат и unless (ако не) и формата If I were you за съвет.
Какво да запомним
- Тип 1: If it rains tomorrow, we will stay at home.
- Тип 2: If I had a lot of money, I would build a wildlife centre.
- If I were you, I would... : съвет (were за всички лица).
- unless = if not: Unless we act now, the problem will get worse.
- В частта с if не се слага will или would.
Пример
