A machine that takes sweat-laden clothes and turns the moisture 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 designed to only let water molecules get through.

Since its Monday launch, its creators say more than 1,000 people have "drunk other's sweat" 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 - 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."

Sit Up Straight: Tips for Improving Your Terrible Posture

The more time we spend sitting in front of our computers, the worse our posture gets. Modern technology is turning us into literally twisted creatures.

In addition to being detrimental to how your body functions, bad posture isn’t cute. It causes you to jut(突出) your hips forward, slump your shoulders, and even breathe inefficiently, according to Pat Davidson, a trainer with a PhD in Exercise Physiology who is the Director of Training Methodology and Continuing Education Coordinator at Peak Performance in NYC.

Davidson explained that bad posture compromises your diaphragm(隔离), the big muscle right below the ribs that helps you take deep breaths. So instead, you start using other muscles, like your shoulders, to help you breathe. It turns out that people with lousy posture don’t walk correctly, and they count on their lower back muscles to help propel themselves forward.

Here are a few quick fixes recommended for correcting your slump:

If you sit at a desk all day, don’t perch on the edge of your chair at work trying to sit up straight. The best thing you can do is keep your hips against the back of the chair and use it for support—that’s what it’s there for.

Get up frequently and walk around.

If you carry a heavy shoulder bag, make sure to carry it on both your right and left shoulder, switching off as each gets tired. Even better: wear a cross-body bag so that the weight’s more evenly distributed.

Work out your core muscles. You can try backwards jump-roping. If the rope hits you, you have the wrong posture. Hula hooping is also a good choice.

Focus on the upper back and shoulder muscles. One of her favorite exercises is having clients stand up against a wall, with your hips touching the wall. Put a tennis ball between your shoulder blades and try to squeeze the ball. Boating is also excellent for improving posture, since it causes you to pull your shoulders up and back.

【1】According to the passage, a bad posture can_____.

a. stop us from taking deep breathes

b. functionally change our body

c. hurt our diaphragm

d. make our walking posture incorrect

A. bcd B. acd C. abc D. abcd

Many people rely on a cup of coffee or two to wake them up in the morning or pick them up during the working day, but now a chemist has come up with a speedy alternative to crafting a cup of coffee.

U.S. biochemist Ben Yu has created `Sprayable Energy,` which claims to be the world`s first caffeine - based topical energy spray.He said tired workers can spray a `shot` of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee.

The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee.

Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe.The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure.Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup.

The website said: `The reason for this is our product not being ingested, isn`t almost entirely metabolised(新陈代谢) by the liver before entering your system and becoming available to your body.`

`Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee.`c`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day.

It claims that after spraying the product on the skin, users will feel `awake and focused without being over-stimulated,` which is common with coffee and energy drinks.

【1】What can we learn about Sprayable Energy from the passage ?_______.

A.A bottle of Sprayable Energyis cheaper than 40 cups of coffee. .

B.Sprayable Energy lets users not worry about taking in unnecessary calories..

C.Sprayable Energy can be used at least 20 sprays a day

D.The caffeine spray is a colorless liquid that is absorbed through the skin..

【2】What does the fifth paragraph mainly tell us ?____

A,Sprayable Energy is taken by mouth...

B.Before Sprayable Energy is absorbed by body, the liver entirely metabolizes it

C.How Sprayable Energy acts on users body and how users use the product.

D.Sprayable Energy is convenient but expensive.

【3】We can conclude from the passage that ____

A.Sprayable Energy can not be permitted to be used by people now.

B. Sprayable Energy has not already gone into mass production

C.each spritz of Sprayable Energy has the same effect as a full cup of coffee

D.Sprayable Energy is well received by flagging workers.

Its reported that powerful Cyclone Pam has impacted at least half the population of Vanuatu, which is a South Pacific island nation.

“Vanuatu is used to disasters but the indications are that Cyclone Pam has caused unprecedented damages,” said President Baldwin Lonsdale in a press release.

The leader of the island nation noted that following a direct hit from the Category 5 storm on Friday, at least two deaths have been confirmed and over 30 injured people are being treated in the Central Hospital in the capital, Port Vila where many people are now homeless and torrential rain has led to severe flooding. He also said bridges which link the capital with the rest of the island have been destroyed.

Mr. Lonsdale made his appeal from Sendai, Japan, where he has been attending since Sunday the Third UN World Conference on Disaster Risk Reduction. The Conference has drawn thousands of Government and civil society delegations to craft a new framework for managing disaster risk which will reduce mortality and curb economic losses.

The country is already threatened by coastal erosion and rising sea levels in addition to five active volcanoes and earthquakes. "This is why I am attending this Conference and why Vanuatu wants to see a strong new framework on disaster risk reduction which will support us in tackling the drivers of disaster risk such as climate change."

Meanwhile, the UN Children’s Fund (UNICEF) reports that it is estimated that at least half the population of Vanuatu has been affected by cyclone Pam. Of these, at least 54,000 are children.

Many homes in Vanuatu have likely been destroyed as they are built with natural and local materials such as thatched and corrugated roofs that are vulnerable to strong winds and floods.

Other Pacific Island countries have been severely impacted as well, including the Solomon Islands, Tuvalu and Kiribati.

A UN Disaster Assessment and Coordination (UNDAC) team was expected arrive in Port Vila late Saturday. OCHA was also expected to deploy three staff with information management, public information and humanitarian coordination as well.
