Question

                                        B 

           The latest technology inventions in 3D printing are rapidly changing how things are being made. 

           At the International Manufacturing (制造业) Technology Show in Chicago,a little-known car maker became popular by manufacturing a car at the show.

           It was a fully functional car that was 3D printed in 44 hours and assembled(装配) in two days. The car is called a “Strati”，Italian for layers,so named by its designer Michele Anoe because the entire structure of the car is made from different layers of materials.

            The average car has more than 20,000 parts but this latest technology reduces the number of parts to 40. uThe goal here is to get the number of parts down and to drop the tooling costs to almost zero,” said John   B. Rogers Jr.? chief manager of Local Motors. “Cars are ridiculously complex,” he added,referring to the thousands of bits and pieces that are sourced,assembled and connected to make a vehicle.

             This technology can use a variety of materials to manufacture anything in complicated detail. Imagine if you could order a new car online according to your needs and pick it up of have it delivered to you the next day at a small part of the cost of buying one from a shop? What if you could make small parts at a lower cost rather than buying them from a parts supplier? What a great change would that be for the industry? It's already happening.

              One of the challenges with collecting antique (古老的) cars is replacing parts. You can't buy them because they're not in use and it's difficult to find the parts that fit. But now people can use 3D printing technology to make parts for their cars.

               John B. Rogers Jr. believes that in the near future a car will be made in just 60 minutes. The company is already organizing a worldwide network of “Microfactories” where you can order and pick up your personalized car.

Answer 1

25. B 26. D 27. D 28. A

B篇(现代技术)

本文是说明文。3D打印汽车的亮相改变了人们对传统汽车制造业的认识，将来人们能真接从网上订购满足个性化需求的汽车。

25. B. 细节理解题。由第一段中的3D printing are rapidly changing how things are being made和第二段中的a little-known car maker became popular by manufacturing a car at the show 可知，在本次展览会上最使人印象深刻的是一辆3D打印汽车。

26. D. 细节理解题。由第三段中的It was a fully -functional car that was 3D printed in 44 hours and assembled in two days. The car is called a “Strati”可知，这辆被称作Strati的汽车是一台真正的运转正常的汽车,在四天之内就完成了打印和装配。

27. D. 写作手法题。由第五段中的第一句可知，本段提出的这几个问题都是为了 说明用3D技术打印汽车的优势。

28. A. 推理判断题。由最后一段中的John B. Rogers Jr. believes that in the near future a. car will be made in just 60 minutes 及 organizing a worldwide network of “Microfactories” 可知，John B. Rogers Jr.对于这一技术的前景很有信心，故选A项。
