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."

3 Ways to Keep Tabs on Your Weight

1. WAIST-TO-HIP RATIO

Measuring your waist-to-hip ratio is an accurate way of monitoring changes to your body shape. 【1】 Grab a tape measure and wrap it around your middle, where your belly button sits. Then do the same around your hips’ widest point. 【2】 A ratio of above 0.8 indicates you could be carrying an unhealthy amount of abdominal fat.

2. BODY MASS INDEX (BMI)

It’s thrown around a lot these days – but your BMI is a number that indicates your weight in relation to your height. 【3】 A BMI above this can mean an increased risk of heart disease and type 2 diabetes, both common weight-related conditions. What’s your BMI? 【4】 Easier still, Google “BMI Calculator” and enter your measurements.

3. WAIST MEASUREMENTS.

Your essential organs – liver, spleen, heart, kidneys and lungs – are located just above the waist region. Carrying any extra weight around your waist brings additional burden to these organs, making it harder for them to work efficiently. 【5】 For men, try to stay under 94cm and for women 80cm.

A. How can we do it?

B. How do you do it?

C. How big is too big?

D. A healthy BMI is between 18.5 and 25.

E. A new standard of BMI will come out soon.

F. Then divide the waist measurement by the hips measurement.

G. Simply divide your weight in kilograms by your height in metres squared.

【题目】Are you single or married? Are you a cat or a dog owner? Do you exercise, or are you a “couch potato” (a person who sits on the sofa all day watching TV, eating and basically doing nothing)? These questions and many others are about your lifestyle.

People in the United States feel that they can choose their lifestyles and even shape their own identities. The great variety of lifestyles leads to constant national discussion of choices that people make. This freedom of choice is fun and exciting, but it also creates stress and uncertainty. In newspapers, lifestyle issues are discussed in the features or style section. In The Chicago Tribune this section is called “Tempo”. People turn to this section for lively discussion on lifestyle choices they face with regard to their personal identities, their families, and their social lives.

Many American people believe that they can make their lives happy and satisfying despite their problems. If they lack confidence or tend to feel anxious, shy, angry, or depressed, they believe that they can change themselves. Self-help books, magazines, and feature articles are filled with advice from experts about steps to take to become a happier or more satisfied person and to improve one’s self-respect. Part of this research for self-improvement is a belief that even one’s own appearance can be controlled. This is why there are so many articles in the newspaper about looking young, wearing the latest fashions, and becoming physically fit.

Lifestyle choices also involve moral and social issues. How should children be raised? How should people behave on a date? How should elderly people be treated? How can people stay happily married? All these kinds of issues are constantly discussed and are constantly changing. Not only are experts such as psychologists consulted, but stars from the political and entertainment worlds are held up as lifestyle leaders as well. In the newspaper, feature articles called profiles（简介）discuss in detail the personal lives or public work of movie stars, authors, artists, and excellent individuals who are not stars. The lifestyle choices these people make contribute to the public discussion of all the issues that people think about.

A well-known advertising slogan is “Just do it.” In the culture of the United States, people believe that they can take action and become the kind of people they want to be and live the way they want to live.
