2、the little finger that can be connected to any mobile handset using Bluetooth. Artist Sean Miles designed the new gloves that double as a phone in part of his project that shows the possibilities of gadget recycling. He uses outdated gloves and combines them with parts from mobile handsets recycled
3、through O2, which commissioned(承担)the project. Mobile phone users will be able to keep their hands warm while they chat without taking their phones out of their pockets or handbags. Mr Miles designed two pairs of the new glovesone in pink and the other in brown and yellow. They will appear in an exh

He said, “Theres a pressing need for all of us to look at outdated handsets, and all the gadgets that we

Sometimes, light slows a bit. The new research is“very impressive work, ”Robert Boyd said. “Its the sort
12、 of thing thats so obvious, you wonder why you didnt think of it first. ”Light travels as particles and as waves. Photons(光子)are the name given to those particles that represent the smallest possible amount of light. At their fastest, photons travel nearly 300 million meters in a single second. That
13、s fast enough to get to the moon and back in about 2. 6 seconds. Scientists had long known, though, that they could slow light photons down by shining them through a material such as glass or water. Still, light moving through a vacuum has usually been assumed to move at peak speed. That would seem
14、to make sense. In a new study, however, scientists show that even racing through a vacuum, light can slow. So the speed of light is more of a universal speed limit than an absolute rule for how fast photons travel. Miles Padgett and his colleagues showed that the key to slowing light is to change th
15、e shape of a light wave. His team raced a pair of photons. One traveled unchanged through a cable made from optical fibers. The other passed through a pair of devices that acted like lenses. A lens changes light: It can focus a spread-out beam of light into a point, for instance. The second photon p
16、assed through one device that changed the shape of its wave and another that changed it back to its original form. The first photon won the race. The second photon came in a tiny bit later, several quadrillionths of a second late for every meter of the race. The 4difference wasnt huge, but it was en
17、ough to measure. Most technology would not pick up such a small change, but it could be important to scientists who study short pulses of light. “Im not surprised the effect exists, ”Boyd said. “But its surprising that it is so large and strong. ”【文章大意】本文主要介绍了光的速度其实并不像人们所想象的那样, 总是很快。有的时候, 它可以慢下来。5.
18、What Boyd said in Para. 2 may mean_. A. it isnt surprising that light can slowB. it is clear that light has a constant speedC. it is a pity that he didnt slow light firstD. it is a wonder that light slows down【解析】选 A。推理判断题。根据第二段的 Its the sort of thing thats so obvious, you wonder why you didnt think
19、 of it first. 可知, 他认为这种现象其实是很明显的, 为什么自己没有提前想到, 说明这并不是一件令人吃惊的事情。6. According to the text, Miles thinks_. A. light photons dont slow down in a vacuumB. the speed of light isnt absolute for photonsC. there is really a limit to the speed of lightD. traveling photons keep an absolute rule of speed【解析】选 B
20、。细节理解题。结合第四段的 So the speed of light is more of a universal speed limit than an absolute rule for how fast photons travel. 可知, 光的速度更是一种普遍的速度限制, 而不是光子运行多快的绝对规则。7. How can people slow light efficiently? A. By keeping light traveling in a straight line. B. By sending light through a cable of optical fib
21、er. C. By focusing a spread-out beam of light into a point. D. By changing the direction of light constantly. 【解析】选 C。细节理解题。从倒数第三段的 It can focus a spread-out beam of light into a point, for instance. The second photon passed through one device that 5changed the shape of its wave and another that cha
22、nged it back to its original form. 及倒数第二段的 The second photon came in a tiny bit later 可知, 把分散的光聚集成一个点可减慢光速。8. What does the underlined word“it”refer to? A. The race. B. The photon. C. A second. D. The difference. 【解析】选 D。词义猜测题。根据倒数第二段的画线词前面的 The difference wasnt huge 可知, 这里的 it 指的就是这个差别。9. What migh
23、t be the most suitable title for the passage? A. Sometimes light is not so fastB. Light can slow in the endC. The light runs fastest in a vacuumD. Light speed is beyond measurement【解析】选 A。主旨大意题。本文主要介绍了有的时候光的速度并不像人们所想象的那样快, 它也有慢的时候。. 完形填空I had been writing in pen and ink before making the change to a
