[试题]PROTECTING EYES FROM COMPUTER SCREENS[部资料]
Many of us spend the bulk of the day looking at computer screens Reading this article means there＇s a good chance you＇re looking at one right now
But does looking at computer screens damage your eyes？Professor Nathan Efron does not consider computer screens harmful to our eyes
But he admits if you use one a lot you increase your risk of becoming slightly more shortsighted–where your eyes focus well only on close objects while more distant objects appear blurred This is especially the case for children and young adults whose eyes are still developing
In the shorter term prolonged viewing of a computer screen can make any slight existing vision defects more noticeable It can also give you what is sometimes known as computer vision syndrome–eye strain headaches gritty eyes and blurry vision But this is only temporary and can be minimized by
Adjusting the screen display so the contrast is high and the brightness feels comfortable
Having lighting that does not produce glare on the screen
Giving your eyes regular rests from looking at the screen (The Optometrists Association of Australia recommends you do this for five to ten minutes every one to two hours of computer use It＇s a good time to make phone calls or do other tasks)
1Many of us spend much time looking at computer screens [答案]T
2Looking at computer screens for long time doesn＇t damage children and young adults＇ eyesight [答案]F
3Computer vision syndrome cannot be weakened [答案]F
4It＇s good taking breaks during screen watching [答案]T
5Proper lighting is important to protect our eyes [答案]T
[试题]NEW MATERIAL CAN COOL BUILDINGS[部资料]
Researchers at Stanford University have developed a new material that can move heat out of buildings and into space The material can cool buildings even on hot days
The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels However instead of turning sunlight into energy as solar panels do the material turns heat into infrared radiation
Shanhui Fan is an electrical engineering professor at Stanford University He says that the panels have a layer of material that is like sand The panels also act like a mirror They take heat out of buildings and reflect the light from the sun Both the heat and sunlight are sent 100 kilometers into outer space
The panels are cool to the touch even in the sun Researchers say they can reduce the indoor temperature to nearly 5 degrees Celsius below the temperature outside
Mr Fan says it is like having a window into space He says the heat is sent directly into space without warming the air Buildings in developing countries that do not have electricity or air conditioning could use the panelsIn areas where one is offgridthere is a significant potential benefit for storing medicine or even food In many of these situations being able to reduce the temperature is important And this would provide a way to do it
The Stanford researchers described their technology in the science publication Nature They say the main problem is creating actual cooling systems using the hightech panels It may be possible to develop a cooling spray technology in the next three to five years that could be used on existing solid structures
1The material can cool buildings only on cold days [答案]F
2The material turns heat into infrared radiation because it is a very thick sheet with many layers that could be placed on a roof like solar panels [答案]F
3The heat of the buildings and sunlight are sent 100 kilometers into outer space by the panels [答案]T
4The offgrid areas may use the panels to reduce the temperature of buildings to store medicine or even food [答案]T
5A cooling spray technology may be developed in the near future that could be used on existing solid structures [答案]T
[试题]WILL EREADERS REPLACE THE CONVENTIONAL PAPER BOOK？[部资料]
Kindles Nooks and other ereaders are threatening the future of printed books But reading itself may get a boost from the devices For example a study found that the kids felt better about reading after a course in which they used Amazon Kindles The research is in the International Journal of Applied Science and Technology
For two months 199 middleschool students in a reading improvement class in Texas had 15 to 25 minutes every day when they were free to read on the Kindle In general the students felt the device improved their reading ability And they tended to enjoy using an ereader
They noted the ease of carrying multiple books in one device and the feeling that reading was suddenly a hightech 21stcentury activity rather than a boring waste of time And some lowlevel readers who might otherwise be embarrassed to be seen with a simple book liked keeping their peers in the dark about what title they were reading In the old days one had to use a fake bookcover to achieve that level of secrecy
1Amazon Kindles is a kind of ebooks [答案]T
2The research done in the International Journal of Applied Science and Technology has lasted for two years [答案]F
3The students felt ebooks could not improve their reading ability [答案]F
4Many students tended to enjoy using an ereader [答案]T
