Can we watch 3D (three dimensional) TV programs without the glasses? With the development of the technology, we can make it soon.

Lately, there has been much progress of this video system by some scientists at the University of Arizona. It is said that the researchers at the University of Arizona have created the world’s first 3D video display that uses an onboard memory and can also be updated. So far the 3D displays produced in the labs can be erased and rewritten in only a few minutes. For a 3D television to be created however, the display would need to be overwritten several times in a second, something to be achieved within the next decade.

This ability to erase and rewrite a 3D projected(投射)image is considered as a huge breakthrough in this field. Indeed it gives lots of hope that even the remaining bits can be achieved. The main challenge now is to come up with methods of continuously erasing and rewriting the image. According to most researchers, an eventual 3D television will have a flat screen construction, which is similar to the modern day displays with flat panels. However, for the case of the 3D television, the display would most likely need to be placed on the floor, right in the middle of the viewing room as is presently done with the coffee table. The image would then be projected above the display screen of the “coffee table”, where it would be viewable in 360 degrees.

While it is quite easy to demonstrate the great potential of the 3D TV in a laboratory setting, it is entirely a different thing to produce in mass. Furthermore, in order to watch a 3D TV, there would be required 3D TV programs. This is no small task as creating even a very cheap 30-minute comedy in the 3D format would need a vast amount of expensive equipment as well as technical knowledge.

It would therefore call for very serious duty by the television networks to adapt to the 3D. But because the technology is there, sooner or later, be put to good use. Even though 3D TVs may not be a reality within the next decade or so, it will eventually get there.

67. From Paragraph 2 we learn that ______.

A. the 3D TVs have begun to be produced in factories in large quantities

B. the 3D TVs are still being researched in spite of some pleasing progress

C. the 3D displays in the labs can’t be erased or rewritten in several minutes

D. the University of Arizona has updated the world’s first 3D video memory

68. What’s the main challenge at present in the field of research 3D TVs?

A. Promote the development of flat screen construction.

B. How to produce as many 3D TV programs as possible.

C. The remaining bits can hardly be achieved though there is hope.

D. How to solve the problem of erasing and rewriting the image non-stop.

69. What’s the main idea of Paragraph 4?

A. To project the 3D TV programs in a laboratory is easy.

B. People prefer a cheap 30-minute comedy to the 3D ones.

C. Nobody will show interests in watching 3D TV programs.

D. To produce 3D TVs in mass still faces a lot of other difficulties.

70. Why does the author write this passage?

A. To tell us how far the 3D TV is from us.

B. To tell people where to buy the 3D TVs.

C. To prove the basic need for the 3D TV programs.

D. To encourage people to research the 3D TV displays.
