【題目】Having Fun "Growing" and "Stealing"

【題目】C

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(膜蒸餾)," 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(驚人的表演) - 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】Which of the following is the disadvantage of the machine?_______.

A.The water processed by the machine is cleaner than local tap water .

B.The amount of water the machine produces is too small.

C.the machine is cheaper than the similar one on the International Space Station

D.The machine can help raise awareness of lacking water in the world .

【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 Mttias 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..

【4】The passage is most likely to be____

A.a tourist brochure.

B.a book review

C.a news report

D.a blog.

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.
