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.

    The device was built for the United Nations' 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 the engineer Andreas Hammar, known locally for his appearances on TV tech show “Mekatronik”. He said the key part of the sweat machine was a new water purification part developed by a company named HVR.

    “It uses a technique called membrane distillation (膜蒸馏),” he told the BBC. “We use a special kind of material that only lets steam through but keeps bacteria, salts, clothing fibers and other things out. They have something similar to the International Space Station, but our machine is cheaper to build. The amount of water it produces depends on how sweaty the person is, but one person's T-shirt typically produces 10ml, about a mouthful.”

    The device has been put on show at the Gothia Cup-the world's largest international youth football tournament. Mattias Ronge, chief executive of Stockholm-based advertising agency Deportivo, 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,” Mattias Ronge said. “So we've equipped the machine with exercise bikes and volunteers are cycling like crazy. Even so, the demand for sweat is greater than the supply. And the machine will never be produced in large numbers, since there are better solutions out there such as water purifying pills.”

    Because of the Internet, people from different parts of the world can connect with one another, and get information about nearly everything in the world. {#blank#}1{#/blank#} They spend so much time online, hardly realizing that much of it is actually wasted on something meaningless.

    Robots come in many shapes and sizes. But most have one thing in common. They are built to help people. Lately engineers have been developing new kinds of humanoid robots. These high-tech machines are designed to lend a hand everywhere from hotels to disaster areas.

    "Robots help people by making their lives easier, safer, and more fun," says engineer Omar Abdelwahed.

    Since November, a robot named pepper has been on the job at the Mandarin Oriental hotel in Las Vegas, Nevada. When guests have questions or need directions, they can ask Pepper. They can also use the robot's touch screen to find the information they need. Pepper is able to talk with guests and entertain them with stories too. It can even tell what kind of mood they are in.

    "Pepper provides our guests with information in an exciting and new way," says hotel manager Donald Bowman.

    For a kid, being in the hospital can be boring and even scary. But a small robot called NAO is helping to make hospital stays easier. It was designed to keep people company.

    A Tennessee doctor named Phil Parker bought a NAO robot three years ago. He programmed it to talk to and play with young patients. He brings it to hospitals to help sick kids. When kids get medical tests, NAO explains what is going on. The robots also reads to kids and plays games with them like rock, paper, scissors.

    "The robot gets many kids to smile for the first time since they've been in the hospital," Parker says.

    Other robots are being developed to help in places where it's hard or risky for people to go. For example, disaster areas can be full of rubble and other dangers. Engineers in Japan are building a robot called E2-DR to go into those areas and search for people who are hurt.

How to escape from a car in water

    "If you get on your phone and call your parents or your sister, or 911, you will die," says Robert May, a 21-year-old veteran(老兵) of the Indiana State. No one else will arrive in time: you have to save yourself.

    Move quickly. Minivans(微型货车) might float for as long as10 minutes. {#blank#}1{#/blank#} In a study from the University of Manitoba, three passengers were able to exist with a child mannequin(人体模型) through a single driver-side window in just 3 seconds.

    Unbuckle(揭开)your seat belt, lower your window and climb out, ideally onto the roof of the vehicle. {#blank#}2{#/blank#}Unfasten them from the backseat, pull them into the front and push them out of your window, oldest ones first. In May's experience, electric car windows will continue to work after falling into water. {#blank#}3{#/blank#}

    Don't open the door, water will flood in. Once full of water, the vehicle will sink fast. {#blank#}4{#/blank#}Vehicle submersions (淹没) have one of the highest death rates of any type of single-motor-vehicle incidents, responsible for 400 deaths a year in North America.

    After you get on top of your car, figure out if it makes sense to stay put or swim for dry ground. {#blank#}5{#/blank#}Just get out first, May says.

A. From there, call for help

B. You will be then totally out of danger.

C. Research has been done to confirm this.

D. If there are children present, attend to them first.

E. In one study, a 65-passanger bus sank in nine seconds.

F. Still, keep a small glass-breaking tool on your key ring, just in case.

G. However, the chances of survival are highest if you get out in the first 60 seconds.

About 5% of all children experience anxiety over school. Not only can this affect their education, but it can also be difficult for you, especially if you have to take time off work because your child won't go to school. Luckily, there are tips that can help you.

{#blank#}1{#/blank#}

Speak with your child to find out why he is anxious. Your child may have a clear-cut reason for not wanting to attend school and knowing what it is that may help you to ease his anxiety. If your child cannot or will not explain the issue, talk with his teacher, who may also be able to help you develop a solution. What also deserves your attention is any recent change at home that may be causing anxiety. Common changes can be such as moving, the loss of a pet, or a divorce. {#blank#}2{#/blank#}

Encourage your child to return to school

{#blank#}3{#/blank#}He may lack the courage to go back to school. So, when you intend to encourage your child, don't ask your child how he feel or place emphasis on his anxiety. {#blank#}4{#/blank#}Wake your child up at the same time each morning, and encourage him to do the same things in the same order each day. If your child refuses to go to school one day, it's important to avoid anything that makes him want to do it again.

Promote self-confidence

This can be achieved in several ways. {#blank#}5{#/blank#}Try to get him involved in a club or activity that he can do outside of school hours, or at least arrange a few play dates for your child to help him see that being with other kids is fun. So, your child gets the confidence in joining others. Apart from that, teach your child self-comfort techniques so he may benefit from knowing how to calm himself down. All these do help him build self-confidence.

C. Make him forget about what makes him anxious

D. Instead, develop a routine to make your child feel safe

E. Encourage your child to participate in more social activities

F. As your child is not grown-up, he may have been trying to escape from it

G. When the cause of anxiety is found, you may consider inspiring your child
