Today in our environmental science lecture, we'll discuss the impact of urban green spaces. A recent study in Melbourne found that adding parks and community gardens can reduce local temperatures by up to 3 degrees Celsius during summer heatwaves. Interestingly, the cooling effect is strongest within 50 meters of the green area, but it diminishes beyond 200 meters. The study also showed that vertical gardens on building walls are less effective than ground-level parks because they provide less shade and water evaporation. However, vertical gardens are valuable in cramped city centers where ground space is scarce. So, while ground-level parks are the priority, we should consider a mix of both designs for maximum benefit.
❓ Согласно лекции, что выявило исследование в Мельбурне об охлаждающем эффекте зелёных зон?
A. A. Наиболее силён он в пределах 50 метров от зелёной зоны.
B. B. Он лучше всего подходит для вертикальных садов на стенах зданий.
C. C. Это снижает температуру на 5 градусов по Цельсию.
D. D. На расстоянии более 200 метров оно не оказывает никакого эффекта.
✅ 正确答案
A. It is strongest within 50 meters of the green area.
