1. (2023·邹平模拟) 阅读下面短文，从每题所给的 A、B、C、D 四个选项中，选出能正确回答所提问题或完成所给句子的最佳答案。

Did you know the colour of the paint on the outside of a building could influence the temperature inside? Scientists have created the whitest paint in the world. They say the paint is so white that it could finally reduce or even avoid the need for air conditioners (空调). The paint made it in the 2022 edition of Guinness World Records as the whitest ever made.

           It turns out that breaking a world record wasn't their goal; controlling global

warming was.

"When we started this project about 7 years ago, we had saving energy and fighting climate change in mind," said Xiulin Ruan, a professor at the university. The idea was to make a kind of paint that would reflect sunlight away from a building. The paint reflects 98. 1% of sunlight while also giving out heat. Because the paint takes in less heat from the sun than it gives out, a surface（表面）with this paint is cooled below the nearby temperature without using power.

Using this new paint is more powerful than the air conditioners.

Two features make this paint super-white. One of this is that the paint has a special chemical called barium sulfate. This chemical is also used in photo paper. Now, the scientists are going to work with a company to put this super-white paint on the market.
