Today in our environmental science lecture, we'll discuss urban green spaces. A recent study in Melbourne found that increasing tree coverage by just 10% can reduce local temperatures by up to 2 degrees Celsius during heatwaves. However, the study also noted that the benefits are not evenly distributed. Wealthier neighborhoods tend to have more mature trees, while poorer areas often lack sufficient green cover. To address this, the city council has proposed a new policy: planting at least 500 trees annually in underprivileged districts. But funding remains a challenge, so they are seeking partnerships with private companies.
❓ メルボルンでの研究は、樹木被覆率を増やすことの効果について何を明らかにしましたか？
A. 熱波の際に気温を華氏2度下げることができます。
B. 地域の気温を最大2度 Celsius 下げる効果があるが、その恩恵は地域によって不均等である。
C. それは裕福な地域だけを助けることになる、なぜなら彼らにはより多くの木があるからだ。
D. 効果を上げるには、毎年500本の木を植える必要がある。
✅ 正确答案
It reduces local temperatures by up to 2 degrees Celsius, but benefits are unequal across neighborhoods.
