Today in our environmental science lecture, we're discussing the impact of urban development on local wildlife. One key point is that many cities have introduced green roofs, which are covered with vegetation. These roofs not only reduce heat absorption but also provide habitats for insects and birds. However, a recent study in London found that while green roofs attract more species than traditional flat roofs, they don't support the same diversity as natural ground-level habitats. The researchers suggest that to maximize biodiversity, we should connect green roofs with ground-level parks through 'green corridors'. Unfortunately, this is often overlooked in city planning due to cost and space constraints.
❓ ロンドンでの最近の研究は、緑の屋根について何を明らかにしましたか？
A. それらは、自然の地上レベルの生息地よりも多くの種を支えている。
B. それらは伝統的な平らな屋根よりも少ない種を引き寄せます。
C. 它们拥有比地面公园更高的生物多样性，但低于自然栖息地。
D. ほとんどの都市計画者にとって、それらは高すぎて考慮に入れることができません。
✅ 正确答案
They have higher biodiversity than ground-level parks but lower than natural habitats.
