When you think of 3D printing, you may think of small objects. But three companies are working together to print something much bigger. They're using a large 3D printer to create the first two-storey(两层的) 3D-printed house in the US.
Usually, 3D printing involves(涉及) a machine building something by putting down many layers(层) of a material—often hot plastic. When the material gets hard, the layers stick together to create a finished object. The method here is similar, but uses concrete(混凝土).
3D printing has been around for a while. But until recently, it hasn't been used much in the US for building houses. Now, that's changing. Several 3D-printed houses have been built in the US and more are planned. So far, no one in the US has created a two-storey 3D-printed house. And this one will be a large, 3-bedroom house. The house, which is in Houston, Texas, was designed by a company called HANNAH. Another company, PERI 3D Construction(建造), provided the 3D printer. And a construction(建造) company called CIVE is doing the actual building.
3D-printed concrete houses are stronger and hold up better in serious storms(暴风雨) than houses built with wood. This can save money in the long run. Since the machine is doing the building, fewer workers are needed, which also saves money.
Ms Lok, who designed the house, says that with 3D printing, it's easy to make each house different from other houses. For example, she's using the 3D printer to create special shelves all through the Houston house. These kinds of changes can be applied(应用于) to almost anything. "The printer doesn't care if you print the same chair 100 times or you print 100 different chairs," says Ms Lok. That means that in the future, each house could be created specially for its owners.

答案
B
【文章大意】本文是一篇说明文，主要介绍了在美国，三家公司正在合作使用大型 3D 打印机打印一座两层房屋。这种房屋使用混凝土作为材料，比木材建造的房屋更坚固，更能抵御严重的风暴。此外，3D 打印还可以根据业主的个人风格定制房屋。
21. B 细节理解题。根据“When the material gets hard, the layers stick together to create a finished object. The method here is similar, but uses concrete.”可知，这座两层的 3D 打印房屋使用的是混凝土作为材料，故选 B。
22. A 细节理解题。根据“The house, which is in Houston, Texas, was designed by a company called HANNAH.”及“Ms Lok, who designed the house, says that with 3D printing, it's easy to make each house different from other houses.”可知，设计这座房屋的是 HANNAH 公司，Ms Lok 是设计师，故选 A。
23. D 段落大意题。根据第四段内容可知，第四段主要介绍了 3D 打印房屋的优点，包括更强的抗风暴能力、节省长期成本、减少工人需求等，故选 D。
24. D 推理判断题。根据最后一段的描述“That means that in the future, each house could be created specially for its owners.”可推断，3D 打印可以帮助人们根据他们的个人风格建造房屋，故选 D。
25. C 标题归纳题。文章主要介绍了在美国，三家公司正在合作使用大型 3D 打印机打印首座两层的房屋，故选 C。
