13、cept, which allows materials to “self-assemble 自行组装 into 3D structures, was initially proposed by Massachusetts Institute of Technology faculty member Skylar Tibbits. Tibbits and his team combined a strand 缕 of plastic with a layer made out of “smart material that could self-assemble in water. They

14、advanced this concept by creating materials that can change into several different complicated shapes, though this kind of material remains the bottleneck of 4D technology.To many people that are just starting to get used to the idea of 3D printers, the name 4D is causing confusion because they cann

15、ot understand where this fourth “dimension coming from. 4D technology shares many of the same principles of 3D printing and is essentially still about creating a new, 3D structure out of certain component; however, Tibbits states the fourth dimension at work here comes from concept of the fourth dim

16、ension of time. The difference between these 3D and 4D creations is that these new forms have the ability to transform and adapt over time.4D printing works through self-assembly a system where “disordered elements form an “ordered structure via an interaction. With these 4D printed materials, these

17、 disordered materials are strands or sheets of specially designed materials. Environmental changes then stimulate 刺激a response from them so that they form a preprogrammed shape.The idea of having adaptable technology that only relies on energy and non-human interactions raises some interesting quest

18、ions about where 4D printing can be used and the practical applications in dangerous environments. This could mean improved infrastructures in extreme conditions, leading to a reduced need for workers to put themselves at risk, but the potential goes even further than that. The technology promises e

19、xciting new possibilities for a variety of applications. A solar panel or similar product could be produced in a flat shape onto which functional devices can be easily installed. It could then be changed to a compact shape for packing and shipping. After arriving at its destination, the product coul

20、d be stimulated to form a different shape that serves its function. Also it could be used to build furniture, bikes, cars and even buildings. As with many of the ideas being put forward, it is easy to go a step too far into the extreme, but this just shows the potential of 4D in comparison to 3D.The

21、 next stage for the research is to move from printing single strands to sheets and eventually whole structures. And water need not be the processs only energy source.1. Which of the following displays the fourth dimension of 4D printing?A. 4D printing creates a new, 3D structure out of certain compo

22、nent.B. 4D technology reduces need for workers to put themselves at risk.C. 4D technology can be used in many more fields than 3D printing.D. 4D printed materials reshape themselves with conditions changing.2. The major problem concerning the development of 4D printing lies in_.A. producing essentia

23、l 4D printersB. creating proper smart materialsC. providing a suitable environmentD. promoting practical applications3. What does the passage lead you to believe?A. 4D printing will take the place of 3D printing in the near future.B. Most aspects of our daily life can be affected by 4D printing.C. 4

24、D printing will benefit humans by saving labor somehow.D. Smart materials can be transformed into other types of material.4. It can be inferred from the passage that_.A. electricity is not used in 4D technologyB. 4D printing has been applied in industryC. more potential of 4D is to be discovered四、短文
