Just put your special clothes on in the morning and you could jump 3 meters into the air and even carry more than 60 kilograms without getting tired. The walk to school would be very, very easy. Such supercharged clothing is one of the products that could be created using "wearable robotics” technology.
Designed to improve a person's senses and skills, the device could be as simple as a hearing aid. Or it could be a full-body suit that senses what you're going to do, then helps you do it better.
“A superman suit would be the final result in wearable robot i cs ”,s a id Francois Pin, head of robotics and energy systems at the Oak Ridge National Laboratory(橡樹林國家實(shí)驗(yàn)室), US. While these suits are at least ten years away, in some areas the technology is already in use.
Researchers are developing artificial- arms and legs that allow old,disabled or injured people to move freely. Thus US Army is interested in using wearable robot legs to help soldiers run faster, carry more equipment and be stronger in battle. Jobs that involve lifting heavy loads or saving lives from the rubble of an earthquake could also become much easier.
A robot is a device that responds to a command. You're probably with simple robots, such as toy cars or airplanes that respond to buttons you push on a remote control.
Wearable robotics goes further. Instead of just receiving information through a wire or remotecontrol- the robotic device can send information back to its controller.
Suppose you wore a sleeve that has sensors where your joints are. Every time you move your arm, the sleeve senses your movements and sends the information to a robot, which then moves its arm just as you did. When the robot hits or touches something, it sends a signal back to the sleeve and you sense the action.
In this way,scientists are working to wrap the robot around the person. Their goal is to make the sleeve, shoe or suit help you do what you want to do.
1.Which of the following can replace the underlined word “supercharged” in Paragraph One?
A, expensive B. overcharged C. advanced D. full of electricity
2.Products resulting from this wearable robotics technology do not include _______.
A.remote controls B.hearing aids C.wearable robot legs D.superman suits
3.From the passage, we can infer that .
A.it will be ten years before robotic devices are in use
B.the wearable robotics technology has been employed in some areas
C.the robots in the robotic devices will do whatever you want to do
D.people must become lazier and less healthier in the future
Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The flood waters also poured vast amounts of raw sewage(未經(jīng)凈化的污水) into the rivers and streams that flow into Narragansett Bay.
It sounds like the makings of an environmental nightmare. But in fact it’s just the opposite. To scientists’ delight. The sewage-loaded floodwaters have caused a well-timed growth of phytoplankton. The microscopic creatures that form the foundation of marine(海洋的) food chains. With more food available for fish. Clams and other sea creatures. The bay’s fisheries industry is expected to benefit.
In decades past. Narragansett Bay typically experienced a late winter early spring algal(海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansen Bay warmed greatly, meriting this seasonal event.
Mark Berman, an oceanographer with the Nationa. Marine Fishertes Service. Said the flood seemed to have sent the bay back in its normal state.
However, local, mutate and federal officials in Rhode Island leave been batting other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runnel flows into the bay. Causing large blooms. But inseam of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow last in the warmer waters. The rapid bacteria growth leads to hypoxia decrease of oxygen in the water that can cause large fish tools. One such die-off occurred in 2003. when millions of oxygen-starved fish washed up on the belches of Narragansett Bay.
The flood’s positive impact will probably be a one-time event, Mr Berman said. Mcanwhile efforts to curb the harmhl summer honors continue; in 2003. for instance, Providence completed a $359 million sewage tonal under the city designated to reduce the polluted storm overflow into Narragansett Bay.
71.Scientists believe that the row sewage flowing into the bay will .
A.pollute the island’s environ mean B.cause lots of property damage
C.increase the fisheries production D.destroy the food chains in the bay
72.The potential benefit of fisherics industry rclics on the .
A.warm temperatures of the bay. B.growth of phytoplankton
C.large summer alga blooms D.consumption of oxygen by beaters
73.People struggle against the summer blooms because they will .
A.pollute the local natural environment
B.increase the prcducmon of fishery industry
C.cause large fish kills of the bay indirectly
D.provide too much food ior sea creatures
74.It can be inferred that .
A.money spent on the summer blooms has been wasted
B.the government is inverting to promote the local fisheries
C.research of accanology should he encouraged
D.she raw sewage impacts are currently con radiator
75.The underlined word “carb” n the hast postage can be defined as “ ”.
A.control B.consume C.cause D.cure

All That noise is damaging Children’s Hearing
Michel become hooked on headphones in his early teens. He walked in the streets of Brooklyn day after day with his favorite music blasting directly into his ears. By his early 20s, Michel had lost much of his upper-range hearing.
The Children’s Hearing Institute reports that hearing loss among children and young adults is rising in the United States, and that one third of the damage is caused by noise.
Surrounded By Noise
We live in a noisy world. Young and old alike are beset by sounds over which we may have little or no control: power mowers, leaf blowers, snow blowers, cars and house alarms, sirens, motorcycles, Jet Skis, loudspeakers, even movie previews.
We attend rock concerts, weddings, parties and sports events at which the music is so loud you can hardly hear the person sitting next to you. At home, televisions, stereos and computer games are often turned up so loud that listeners can not hear a doorbell or telephone. Many “modern ” restaurants have chosen noise enhancement instead of abatement(減輕). Any time you need to shout to be heard by someone near you, your hearing is most likely to be in a decibel(分貝) danger zone.
As if environmental noise were not enough, now we surround children with noisy toys and personal listening devices that can permanently damage their hearing. Toys that meet the safety standards of the American Society for Testing and Materials can produce sound up to 138 decibels, as loud as a jet plane taking off. Yet workplace rules require hearing protection for those exposed to noise above 85 decibels.
Protecting Young Ears
Before buying noisemaking toys, parents would do well to listen to how loud they are. If the toy comes with a volume control, monitor its use to make sure it is kept near the lowest level. Consider returning gifts that make loud noises, disable the noise-making function. Or limit the use of noisy toys to outside play areas.
Children who play computer games and stereo equipment should be warned to keep the volume down. Time spent in video arcades, where the noise level can be over 110 decibels, should be strictly limited. Most iPods have a control that allow parents to set a maximum volume.
Don’t take children to loud action movies. If you do go and the sound seems deafening, ask the manager to turn down the volume or insist on you money back. Children who play in bands and teenagers who use power tools, gardening equipment or guns should be made to wear hearing protection, available at sporting goods stores.
The League for the Hard of Hearing urges parents to encourage participation in quiet activities, like reading, watching family-oriented films, doing puzzles, making thins with construction toys, playing educational computer games, drawing and painting, and visiting librarians and museums.

My house is made of wood, glass and stone. It is also made of software.
If you come to visit, you'll probably be surprised when you come in: Someone will give you an electronic PIN to wear. The PIN tells the house who you are and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights near you, and then turns them off as you walk away from them. Music moves with you, too. If the house knows your favorite music, it plays it for you. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to want something. There is a home control console (控制臺) which is a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you the key to my car, you can use my car. The car works for you because you have the key. My house works for you because you wear the PIN or hold the console.
I believe that in ten years from now, most new houses will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've got.
I like to try new ideas. I know that some of my ideas will work better than others'. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, ”How did I live without them?”
