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.”

    Whether you're up for a Crocodile Dundee's adventure or you'd just like a taste of the Australian sun, the beaches in and around Sydney can offer you all that and more.

Sydney Beach

    Sydney Beach is located at Sydney's northernmost tip on an extension(延伸) of land ending at Palm Beach. Before checking out the golden sand, take a quick tour of the houses of millionaires from the art and film industries.

Palm Beach

    Only about an hour from downtown Sydney, Palm Beach offers a long stretch(延伸) of clean sand and water. With parking near the center of the beach, that leaves the rest of it as a peaceful location with a sparse population, from which you can go surfing but take care — without the huge crowds of other Sydney's beaches, Palm Beach doesn't afford quite the safety level to be found elsewhere. Volunteer lifesavers are on duty only on weekends and holidays.

Bondi Beach

    For the famous beach, Bondi Beach has to be your choice. Parking is difficult to find even on slow days, so consider taking public transport to this world—known beach in the eastern Sydney suburbs. Easily reachable by taxi, bus, and rail, Bondi Beach offers sun bathing, swimming, snorkeling, and all sorts of water sports fun. If you're in the mood for a bit of exercise, two scenic coastal walks will afford you great views and sights along the shore. Take in views from Mackenzie's Point. It starts at Bondi and heads south to Bronte Beach. But don't try to swim in Mackenzie's Bay — it holds dangers such as hidden rocks.

Bronte Beach

    Your second choice for a scenic coastal walk covers a few miles and takes you from Bronte Beach to Waverly Cemetery, where many famous Australians are buried, including the poet Henry Lawson.

Whenever the sun dropped and the blue sky came up, my father and I used to climb the mountain near my house. Walking together, my father and I used to have a lot of conversations through which I learned lessons from his experiences. He always told me, "You should have goals like climbing the mountain. " without the mountain-climbing that we both enjoyed, we couldn't have enough time to spend together because my father was very busy. I really got a lot from mountain-climbing. It gave me time to talk with my father and to be in deep thought as well as develop my patience.

Once we climbed a very high mountain. It was so challenging for me because I was only ten years old. During the first few hours of climbing, I enjoyed the flowers and trees, and the birds'singing, but as time passed, I got a pain in both of my legs. I wanted to quit climbing. In fact, I hated it at that mountain, but my father said to me, "You can always see a beautiful sky at the top of the mountain, but you can't see it before you reach the top. Only there at the top can you see all of the nice things, just like in life. "

    At that time, I was too young to understand his words. But later after that, I got new hope and confidence. I found myself standing at the top of the sky, which was as clear as crystal.

    What do you do when you need to look something up? Go to the library? Open an encyclopedia(百科全书)? Click onto the Internet? These days, most people go straight to Wikipedia, the online encyclopedia. But how reliable is it?

    There's no denying the popularity and usefulness of Wikipedia. It attracts as many as 78 million visitors every month, and the site is available in more than 270 different languages. It's one of the most comprehensive resources available, which includes almost all details, facts and information that may be concerned. It's got much more information than an ordinary encyclopedia. The site is updated on a daily basis by thousands of people around the world. Anyone with an Internet connection can log on and edit the contents or add a new page. And you don't need any formal training.

Of course, there are some controls. Wikipedia has a team of more than 1,500 administrators who check for false information. And main targets for harmful comments(such as politicians) are off-limits to public editing. But with more than 16 million articles to keep an eye on, it isn't easy. So, while Wikipedia benefits from being constantly updated with information from all over the world, it's also open to “vandals”（恣意破坏公共财物者）.

    Some of the damage is easy to notice. One person drew devil horns and a moustache on Microsoft chairman Bill Gate's photo, while another edited Greek philosopher Plato's biography to say he was a “Hawaiian weather man who is widely believed to have been a student of 'Barney the purple Dinosaur'.

    But other things are harder to spot. The most common form of vandalism (恣意破坏公共财物罪)involves adding tiny items of false information into the biography of a famous person. Unbelievably, some of this misinformation has appeared in newspapers, with The Daily Mail, The Guardian and The Independent all having fallen victim to the dirty tricks. For example, in an article about British comedian Sir Norman Wisdom, one newspaper claimed that he co-wrote Dame Vera Lynn's wartime hit There'll be bluebirds over the White Cliffs of Dover. He did no such thing. And in other article, it was reported that TV Theme tune composer Ronnie Hazlehurst had written the S Club 7's hit Reach again, not true. So, if you're going to use any information from Wikipedia, make sure you double-check it first.

    The weather affects many aspects of people's daily life. Knowing and understanding what the weather is doing is useful.

    However, the weather is also one of the most unpredictable elements in the world. Although many people watch the morning news and gather the information about the weather, this is often wrong. Whole days can be ruined by believing that the weather will be one thing, when it turns out to be another. However, owning wireless weather stations allows the owners to monitor the weather for themselves.

    Not only will these weather stations allow the owners to see what the weather is doing, but it is personalized(个性化)to them and their area. Wireless weather, stations are specifically prepared for the immediate neighborhood. Plans will be able to be made, and important decisions will no longer be ruined by bad weather.

    Although these weather stations are typically seen in homes, they can also be used very easily on farms and fishing boats. Both farmers and fishermen rely on the weather for their business and using up-to-date weather information is quite indispensable. By using the wireless weather stations, it can determine for them when to harvest crops and head back to the shore. Because of the size of the weather station, they can be moved very easily and used wherever necessary for people.

    The wireless weather stations are great for all homes, especially for areas that suffer from extreme weather conditions. The up-to-date, instant weather reports will allow a person to monitor what the weather is doing and if the bad weather is heading in their direction. Extreme weather tends to come very quickly; therefore, any information that is received is helpful.

    The weather stations are very simple to set up and are run by solar panels(太阳能板), ensuring they will work even if there is a power-cut. They are far smaller than those in previous years and give a couple of very simple read-outs for the owner. They are easy to use and fascinating to understand.

The last few days before Christmas passed quickly and it was soon Christmas Eve. That night when everyone went to bed, Bunny couldn't sleep. He still couldn't think of what he wanted his Christmas gift to be. He wondered how Father Christmas would know what to bring him if he didn't know himself.

As he was sitting up in bed, Bunny heard a big noise on the roof (屋顶) and a sound downstairs. It was Father Christmas, he realized. Bunny jumped out of bed and raced down the hall to the stairs hoping to have a look at the old man with his own eyes.

By the time Bunny reached the bottom of the stairs, though, everything was again silent. Beautiful gifts were piled (堆积) under the Christmas tree, but Father Christmas was gone. He looked for him for a few minutes, but it was already too late. Bunny turned to climb back upstairs when he heard a cry.

"Hello," said Bunny. "Is anybody there? "

He was answered by another cry. Bunny looked around the big pile of gifts to see what was making the noise. Right under the tree was a funny looking brown animal with big feet and sad eyes. Bunny might have mistaken it for a dog, if it hadn't been for the antlers (鹿角) on its head.

"Are you a reindeer (驯鹿)?" asked Bunny.

"Yes," replied the animal. "My name is Ralph."

"And you were pulling Father Christmas's sled (雪橇)?"

"I was until I got airsick (晕机), " replied Ralph. "I'm afraid I wasn't cut out for the job. Now I'm stuck here and I don't know how to get back to the North Pole."

"Well, if you like, yon can stay with us as a friend," said Bunny. As he made the offer, Bunny suddenly realized the gift he wanted from Father Christmas was a new friend!
