Welcome to today's lecture on urban planning. One key challenge is balancing green spaces with housing needs. In many cities, parks are being replaced by apartment blocks, which reduces biodiversity. However, a recent study in Melbourne found that rooftop gardens can partially offset this loss. These gardens provide habitats for insects and birds, and also lower building temperatures. Interestingly, the study showed that vertical gardens on walls were less effective for cooling than rooftop ones, but they were better at reducing noise pollution. So, while rooftop gardens help with climate, wall gardens improve acoustic comfort.
❓ 墨尔本的研究发现，屋顶花园与垂直墙面花园相比有何不同？

C. 屋顶花园有助于降低温度，而墙面花园则能减少噪音。
D. 两种类型的花园对生物多样性同样有效。
✅ 正确答案
Rooftop gardens help with lowering temperatures, while wall gardens reduce noise.
