Today we're discussing the impact of urban green spaces. A recent study in Manchester found that adding trees and parks to city centers can reduce summer temperatures by up to 4 degrees Celsius. This is mainly because plants provide shade and release moisture through transpiration. Interestingly, the effect is strongest within 50 meters of the green area, but it diminishes rapidly beyond that. The researchers also noted that vertical gardens on buildings have a smaller cooling effect compared to ground-level parks, though they save space. However, the study warns that increasing green spaces alone won't solve heat issues unless combined with lighter-colored paving materials.
❓ ¿Qué reveló el estudio de Mánchester sobre el efecto de enfriamiento de los espacios verdes urbanos?
A. A. Los jardines verticales enfrían de manera más efectiva que los parques a nivel del suelo.
B. B. El efecto de enfriamiento es más notable dentro de los 50 metros de las áreas verdes.
C. C. Los árboles reducen la temperatura de las ciudades en un promedio de 6 grados Celsius.
D. D. Los espacios verdes no tienen impacto en la temperatura a menos que se combinen con pavimentos claros.
✅ 正确答案
B. The cooling effect is most noticeable within 50 meters of green areas.
