Этап 3: Аудирование и чтение/
3.1 Чтение текста (10 минут)
Текст для чтения вслух:
The cooling system in a vehicle is essential to keep the engine from overheating. The main components are the radiator, water pump, thermostat, cooling fan, and coolant. The water pump circulates coolant through the engine and radiator. The thermostat regulates the temperature by opening and closing to allow coolant flow. The radiator transfers heat from the coolant to the air, assisted by the cooling fan. If the system fails or the engine overheats, it can cause serious damage.
Answer the questions:
1. What are the main components of a cooling system?
2. What is the function of the radiator?
3. Why is the thermostat important?
4. What happens if the cooling system fails?
3.2 Упражнение на понимание — ответить на вопросы.
· После чтения ученики отвечают вслух или письменно. Могут работать в парах, обсуждая ответы.
Этап 4: Говорение и закрепление материала (15 минут)
4.1 Обсуждение вопросов в парах или группах:
· How does a cooling system work?
· What components are involved?
· What might happen if a component malfunctions?
4.2 Make up a dialogue. One of you is a mechanic. Another is a customer.
Пример диалога:
Customer: Can
you explain how the cooling system works?
Mechanic: Yes,
of course. The cooling system includes a radiator, water pump, thermostat, and
fan. The
water pump circulates coolant through the engine...
