[2025 原创] A California company called Savor has created a butter - like spread that's made from carbon dioxide (${CO_{2}}$) (二氧化碳) instead of milk. ${CO_{2}}$ is a greenhouse gas that traps heat and causes climate change.
Traditionally, butter is made from the fat in milk or cream from farm animals. But raising the animals produces about 14.5% of the world's greenhouse gases. Plant - based butter also requires land, water, and space to grow.
Savor wanted to create a kind of butter that tasted great and was also planet - friendly. Fats like butter are made up of chains of the elements hydrogen (氢) and carbon. Elements are simple chemicals that can't be broken down into smaller parts.
Scientists at Savor pulled ${CO_{2}}$ from air and combined it with hydrogen and oxygen to create fat, then mixed the fat with water to turn it into butter. They added a substance (物质) called beta - carotene (β胡萝卜素) for color and rosemary (迷迭香) for taste.
Savor's animal - free butter helps the earth in two ways: It removes ${CO_{2}}$ from the air, and it does not rely on limited resources to raise farm animals or grow crops. And, according to early reports, it tastes good, too. “I couldn't believe I wasn't eating real butter,” said a person, who has funded Savor. The product will be available to consumers within a year or two.
() 1. What gas does Savor use to make its butter?
A. Methane.
B. Carbon dioxide.
C. Nitrogen.
D. Ozone.
() 2. Why is traditional butter production harmful?
A. It uses too much water.
B. It costs too much money.
C. It tastes very bad.
D. It pollutes the environment.
() 3. What can we learn about traditional butter and plant - based butter from the text?
A. Both do no harm to the environment.
B. Plant - based butter produces more greenhouse gases.
C. Neither of them avoids environmental influence.
D. Traditional butter uses less water than plant - based butter.
() 4. What does the underlined sentence mean about Savor's product?
A. It is the same as dairy butter.
B. The person was disappointed by its taste.
C. It tastes almost like real butter.
D. The product requires more development.
() 5. What is the best title for the material?
A. Savor used ${CO_{2}}$ to make butter
B. A new company was started
C. ${CO_{2}}$ was turned into beta - carotene
D. Rosemary makes butter taste better

1. B 细节理解题。根据文章第一句可知,这个公司使用二氧化碳来制作黄油,因此 B 项正确。
2. D 细节理解题。根据第二段前两句可知,传统黄油生产有害的原因是饲养动物会产生温室气体,从而污染环境,因此 D 项正确。
3. C 细节理解题。根据第二段可知,传统黄油生产会产生温室气体,以植物为基础的黄油生产也需要土地、水和空间,所以它们都不能避免对环境的影响。故选 C 项。
4. C 词义猜测题。根据画线句可知,这个产品尝起来几乎和真正的黄油一样。故选 C 项。
5. A 主旨大意题。根据全文内容可知,文章主要介绍了一家公司利用二氧化碳制作的新型人造黄油,A 项符合文章主旨。故选 A 项。
