B
The latest technology inventions in 3D printing are rapidly changing how things are being made.
At the International Manufacturing (制造業(yè)) 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(裝配) 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.

26. What do we know about the “Strati” car?

27. The questions in Paragraph 5 are raised to.
A. analyse the latest technology
B. challenge traditional car makers
C. explain how the change happened
D. show the advantage of the technology
28. What is John B. Rogers Jr's attitude towards the technology?

B篇(現(xiàn)代技術)
本文是說明文。3D打印汽車的亮相改變了人們對傳統(tǒng)汽車制造業(yè)的認識,將來人們能真接從網(wǎng)上訂購滿足個性化需求的汽車。
25. B. 細節(jié)理解題。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,在本次展覽會上最使人印象深刻的是一輛3D打印汽車。
26. D. 細節(jié)理解題。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,這輛被稱作Strati的汽車是一臺真正的運轉(zhuǎn)正常的汽車,在四天之內(nèi)就完成了打印和裝配。
27. D. 寫作手法題。由第五段中的第一句可知,本段提出的這幾個問題都是為了 說明用3D技術打印汽車的優(yōu)勢。
28. A. 推理判斷題。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.對于這一技術的前景很有信心,故選A項。

C
Crime-fighdng technology is getting more sophisticated(高級的) and rightly so. The police need to be equipped for the 21st century. In Britain we ve already got the world's biggest DNA database. By next year,the state will have access to the genetic(基因的) data of 4. 25 million people: one British-based person in 14.Hundreds of thousands of those on the database will never have been charged with a crime.
Britain is also reported to have more than four million CCTV (closed circuit television) cameras.
There's a continuing debate about the effectiveness of CCTV. Some evidence suggests that it's helpfiil in reducing shoplifting and car crime.It has also been used to successfully identify(識別)terrorists and murderers. However,many claim that better lighting is just as effective when it comes to preventing crime, and that cameras could displace (轉(zhuǎn)移) crime. A police report said that only one crime was solved for every l,000 cameras in London in 2007. In short,there's conflicting evidence about the effectiveness of cameras,so it's likely that the debate will continue.
Professor Mike Press,who has spent the past decade studying how design can contribute to crime reduction,said that,in order for CCTV to have any effect,it must be used in a targeted way.
Most cameras that simply record city centres continually — often not being watched 一 do not produce results. CCTV can also have the opposite effect of that intended,by giving citizens a false sense of safety and encouraging them to be careless with property(財產(chǎn)) and personal safety.
Professor Press said:“All the evidence suggests that CCTV alone makes no positive influence on crime reduction and prevention at all. The weight of evidence would suggest' the investment is more or less a waste of money unless you have lots of other things in place.”He believes that much of the increase is driven by the marketing efforts of safety companies who promote the crime-reducing benefits of their products. He described it as a “l(fā)azy approach to crime prevention" and said that authorities should instead be focusing on how to change the environment to reduce crime.
28. Why did Britain set up a DNA database?
A. To beat crime.
B. To lead the world.
C. To access other countries’ database.
D. To improve their medical technology.
29. What does Paragraph 2 mainly talk about?
A. CCTV has many negative effects.
B. CGTV is ineffective in reducing crime.
C. People's views on the effectiveness of CCTV vary.
D. Better lighting leads to a greater crime reduction than CCTV.
30. What is Professor Mike Press's attitude toward CCTV?
A. Unconcerned. B. Unsatisfied.
C. Positive. D. Cautious.
31. According to Professor Press,a good way to prevent crime is .
A. to change the environment
B. to use more cameras in the future
C. to promote the marketing of safety products
D. to remind citizens to be careful with their property
