《2025年高考模拟试题汇编高中英语》

C
Concrete has served as the foundation stone of the construction industry for hundreds of years. However, the process of producing concrete is one of the most environmentally unfriendly processes in the world. In the process, not only is carbon dioxide(二氧化碳) released into the air by the energy used to heat the limestone, but the limestone itself also gives out a huge amount of the element.
Luckily, a number of start-ups throughout the world are using creative thinking to make the construction industry a whole lot more friendly for the planet.
A Canadian company called CarbonCure has found a way to inject(注入) concrete with carbon dioxide itself. Not only does this trap the carbon dioxide into the concrete, keeping it from running away into the atmosphere, but it also creates a super strong material called calcium carbonate, which reduces the total amount of concrete that needs to be used.
California-based Brimstone, is creating carbon-negative concrete by doing away with limestone entirely and instead using silicate rock, a material that does not release carbon dioxide when heated. Instead, the process produces magnesium(镁), which absorbs carbon dioxide, as the basis for their concrete.
Additionally, researchers at Australia's RMIT University have recently released a study showing that adding coffee grounds instead of sand to concrete could make it much stronger, reducing both the amount of sand used, as well as the amount of concrete that would need to be used in the final product.
The biggest barrier at this point is convincing members of the industry that the new types of concrete are safe to be used, according to Stacy Smedley, director at a nonprofit focused on decarbonizing construction.
Hopefully these new solutions to the environmental problems of concrete will soon be widely adopted. Given the significant part the construction industry has in releasing carbon dioxide into the atmosphere, great improvements can be made when more environmentally-friendly materials are used.
28.What is the environmental issue associated with traditional concrete production?
A. The high demand for energy.
B. The processing of waste materials.
C. The mass release of carbon dioxide.
D. The use of non-renewable resources.
29.How does CarbonCure deal with the environmental impact of concrete production?
A. By using silicate rock as the basis.
B. By putting carbon dioxide into concrete.
C. By replacing sand with coffee grounds.
D. By absorbing carbon dioxide with magnesium.
30.According to Smedley, what is the major challenge facing these solutions?
A. Difficulty in making profits.
B. Convincing the public of the convenience.
C. Lack of funding for research.
D. Removing the industry members' safety concerns.
31.What is the author's purpose in writing the text?
A. To promote an alternative to concrete.
B. To advocate environmental protection.
C. To introduce new ways to produce concrete.
D. To emphasize the significance of creativity.
