2、crophone into 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 He uses outdated gloves and combines them with parts from mobile hand

The 41-year-old said, “I hope that myTalk to the Handproject will get people to think again about the waste created by not recycling gadgets
6、. If a few more people recycle their gadgets rather than send them to trash, I think this project will have fulfilled its aim. ” Bill Eyres, head of O2 Recycle, urges people to recycle their phone responsibly. He said, “Theres a pressing need for all of us to look at outdated handsets, and all the g
7、adgets that we move on from or upgrade each year. Whether they are consoles 1 or cameras, we should think of them as a resource that we need to recycle responsibly rather than throw them away. ” 【文章大意】本文主要介绍了一种利用废弃的东西制成的新型的手套, 这种手套可以用来打 电话。 1.

New experiments show that may not be true, even within a vacuum. Sometimes, light slows a bit. The new research is“very impressive wo
12、rk, ”Robert Boyd said. “Its the sort 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 mi
13、llion meters in a single second. Thats 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
14、 move at peak speed. That would seem 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
15、 key to slowing light is to change the 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 poi
16、nt, for instance. The second photon passed 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
17、difference wasnt huge, but it was enough 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
18、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. What Boyd said in Para. 2 may mean_. 3 A. it isnt surprising that light can slow B. it is clear that light has a constant speed C. it is a pity that he didnt slow light first D. 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 that
19、s so obvious, you wonder why you didnt think 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 vacuum B. the speed of light isnt absolute for photons C. there is really a limit to the speed of light D. traveli
20、ng photons keep an absolute rule of speed 【解析】选 B。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.
21、B. By sending light through a cable of optical fiber. 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 c
