在本周牛津大学的演讲中，朱博士建议我们将市镇的屋顶以及路面都漆成白色，因为这将有助于地球反射而不是像以前那样保留太阳的热量。

Speaking at Cambridge University this week, Dr Chu suggested we paint the roofs and pavements of our towns and cities white, as it will help the planet reflect, rather than retain, heat from the sun.

他们的救星是一种新型的屋顶：一种闪亮的白色塑型覆盖材料。 专家们说，这种新型屋顶不仅仅是一种保温材料，还能帮助我们的地球降温。

Their solution was a new roof: a shiny plasticized white covering that experts say is not only an energy saver but also a way to help cool the planet.

这主意看起来很酷：将全世界的屋顶刷白来反射更多的阳光，它能帮助城市和地球降温。

Seemed like a cool idea: paint the world's roofs white to reflect more sunlight, and it could help cool down both cities and the planet.
