Today in our environmental science lecture, we'll discuss urban heat islands. Cities tend to be warmer than surrounding rural areas due to concrete and asphalt absorbing heat. However, one effective mitigation strategy is increasing green spaces. A study in Melbourne showed that adding parks and street trees can reduce local temperatures by up to 4 degrees Celsius. Interestingly, the placement of green spaces matters more than their total area. For example, small distributed gardens are more effective than one large park. This is because they create cooling corridors that allow air to circulate. Additionally, green roofs on buildings can help, but they are less impactful than ground-level vegetation.
❓ Согласно лекции, что выявило исследование в Мельбурне о зеленых зонах и городской жаре?
A. A. Крупные парки снижают температуру больше, чем небольшие сады
B. B. Расположение зелёных зон важнее, чем их общая площадь
C. C. Зеленые крыши являются наиболее эффективным методом охлаждения
D. D. Бетон поглощает меньше тепла, чем асфальт
✅ 正确答案
B. The location of green spaces is more important than their total size
