Good morning, everyone. Today, I'd like to continue our discussion on urban planning. We've talked about the importance of green spaces, but let's focus on a specific challenge: the 'heat island' effect. In cities, concrete and asphalt absorb heat during the day and release it at night, making urban areas significantly warmer than surrounding rural areas. One effective solution is to increase the number of parks and rooftop gardens. However, a recent study in Manchester found that while parks help cool their immediate vicinity, their effect diminishes beyond about 300 meters. Therefore, planners should distribute smaller green spaces throughout neighborhoods rather than concentrating them in one large central park.
❓ Según la conferencia, ¿qué reveló el estudio en Mánchester sobre los parques?
A. A. Los parques son más efectivos cuando se concentran en una gran área central.
B. B. El efecto de enfriamiento de los parques se limita a una corta distancia del parque.
C. C. Los jardines en azoteas son más efectivos que los parques para reducir el calor.
D. D. Las áreas urbanas son más frescas que las áreas rurales debido a los espacios verdes.
✅ 正确答案
B. The cooling effect of parks is limited to a short distance from the park.
