Good morning, everyone. Today, we're going to discuss the role of urban parks in reducing heat island effects. A recent study in Melbourne compared three types of green spaces: small gardens, medium-sized parks, and large forested areas. The researchers measured air temperature during a heatwave. Surprisingly, the small gardens had a cooling effect of only 1 degree Celsius, while the medium parks reduced temperatures by 3 degrees. However, the large forested areas showed the most significant drop, up to 5 degrees, but only if the tree canopy was dense. The study also noted that water features, such as ponds, did not enhance cooling unless combined with shade.

A. A. 작은 정원이 중간 규모의 공원보다 더 효과적이었다.
B. B. 울창한 수관을 가진 대규모 산림 지역이 가장 큰 냉각 효과를 제공했다.
C. C. 수경 시설만으로도 온도를 크게 낮추는 효과가 있었다.
D. D. 모든 녹지 공간이 동일한 냉각 효과를 가지고 있었다.
✅ 正确答案
B. Large forested areas with dense canopy provided the greatest cooling.
