Today, in our environmental science lecture, we're discussing urban green spaces. A recent study in Melbourne found that adding more parks and trees can reduce the city's average temperature by up to 2 degrees Celsius during summer. However, the researcher noted that the cooling effect is strongest within 400 meters of a green area, and it diminishes with distance. Interestingly, the study also showed that vertical gardens on buildings have a minimal impact compared to street-level trees. Therefore, city planners are now prioritizing the creation of small pocket parks in densely populated neighborhoods rather than large remote parks.
❓ Согласно лекции, что выявило исследование в Мельбурне об охлаждающем эффекте зелёных зон?
A. A. Оно наиболее сильное в пределах 400 метров от зелёной зоны.
B. B. Он одинаково эффективен для вертикальных садов и деревьев.
C. C. Это работает только для больших парков за городом.
D. D. Это снижает температуру на 2 градуса зимой.
✅ 正确答案
A. It is strongest within 400 meters of a green area.
