Article: 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 others' sweat(h)" 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 ," 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 - 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... Question: What does Mattias Ronge think of the machine? _ Yes or no, is the answer "The machine is not worth popularizing."?
No

Article: FROM 1964 to 1978, Dazhai, with a population of 500, was the most famous village in China. Millions of Chinese came to the Shanxi village to visit its terraced fields and "splendid" irrigation systems. It was not until 1978 when Guo Fenglian, head of the village, paid a visit to the US that China's model village found how far it had fallen behind those in developed countries. "I was astonished at their modern equipment in harvesting, which could even separate big tomatoes with small ones," said Guo. "American farmers' life quality also impressed me a lot. Every day they had two cups of milk, which is something we don't have even in our wildest dreams." "We have to learn their advanced technology and administration for our own development," said then first Deputy Prime Minister Deng Xiaoping who was planning China's reform and opening up policy then. "Through opening our doors, we would not only take advantage of foreign funds , but also create job opportunities and cultivate talents." In 1978 Japanese electricity giant Panasonic came to China as the first foreign business to invest here and its success attracted other world brands into exploring the Chinese market. So far China has for 15 years taken in the world's second biggest foreign investment, following the US, to help set the country in a fast growth. However, China's 30-year road of reform was not always smooth. Doubts on the reform began to rise at the end of the 1980s as many people worried the country would turn to capitalism . "The criterion for our judgment is whether it helps develop socialist productive forces, whether it helps increase the overall national strength of a socialist country, and whether it brings about better living standards," said Deng. "China's reform and opening up is a unique success story. It has brought benefit to both China and the world," said William Keller, chief manager of a Swiss pharmaceutical company. Question: Many people have doubts about the reform _ . Yes or no, is the answer "at the end of the 1980s"?
