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(橡树林国家实验室), 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

A machine that takes sweat-laden clothes and turns the moisture（分子） into drinking water is in use in Sweden. The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane(膜) designed to only let water molecules get through.
Since its Monday launch, its creators say more than 1,000 people have “drunk others’ sweat（h汗液）" in Gothenburg. They add the liquid is cleaner than local tap water.
The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water.
The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik. He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology.
"It uses a technique called membrane distillation(膜蒸馏)," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine(尿液) - but our machine was cheaper to build. Volunteers have been sampling the treated sweat since the start of the week in Gothenburg .“The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful."
The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament. MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt(惊人的表演) - said the machine had helped raise awareness for UNICEF, but in reality had its limitations.
"People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for sweat is greater than the supply. And the machine will never be mass produced - there are better solutions out there such as water purifying pills."
1.What can we infer from the passage ?_______.
A. The water processed by the machine is cleaner than local tap water .
B. The machine can help raise awareness of lacking water in the world .
C. The machine is cheaper than the similar one on the International Space Station
D. The amount of water the machine produces is roughly a mouthful.
2.What is the main idea of the fifth paragraph ?
A. How the machine works.
B. Who developed the machine.
C. How the machine was invented.
D. Why the machine was invented..
3.What does Mattias Ronge think of the machine?____
A. The machine can solve the severe water shortage in the world.
B. People do not like the water the machine processes
C. The machine should be used in rather hot areas in summer.
D. The machine is not worth popularizing.

A machine that takes sweat-laden (浸满汗水的) clothes and turns the sweat into drinking water is in use in Sweden. The machine makes the clothes turn round quickly, heats them to remove the sweat, and then passes the steam through a kind of special material to make purified water.
Since it has been brought into use, its creators say more than 1000 people have drunk others’ “sweat” in Gothenburg. They add the liquid is cleaner than local tap water.

1.Which of the following is the disadvantage of the sweat machine?
A.The amount of water the machine produces is rather limited.
B.It takes too long for the machine to produce water.
C.It costs a large amount of money to build the machine.
D.The water processed by the machine is not clean enough.

A.780 million people in the world lack access to clean water
B.a machine which turns sweat into drinking water is invented
C.a better solution to purifying dirty water is discovered
D.the pill which turns dirty water into clean water is produced
