Environmental authorities handed more than 2,000 cases of suspected environmental law violations to the police, more than double the figure for the past 10 years combined. Close to 3,400 companies and 3,700 construction sites were also found to have violated environment laws and more than 3,100 workshops were closed following air quality inspections by Ministry of Environmental Protection ( MEP) officials and drones , Chen said. The announcement came as a result of long lasting heavy smog in Beijing and the neighboring Tianjin and Hebei province for the better part of a week. The next step is to further optimize the country's industry, and energy structure and cut back one missions of air pollutants, Chen said. Authorities will go on cutting back on outdated factories this year, shut down l,000 small coal mines, improve the quality of coal on the market, guarantee stable supply of natural gas, and promote the use of clean energy and energy-saving buildings. Chen said efforts will also be made to improve the evaluation of governments' carrying out of air pollution control measures, deepen regional cooperation, step up technological research and sharpen laws and regulations in the field, to make polluters nay the "unaffordable price".

Article: Scientists from the Max Plank Institute for Biological Cybernetics in Tubingen, Germany, have presented the first experimental evidence that people do end up walking in circles if lost in unfamiliar areas.The study, published in the journal Current Biology, examined the tracks of people who walked for several hours in the Sahara desert in Tunisia and in the Bienwald forest in Germany.Researchers Jan Souman and Marc Ernst said the scientists used the global positioning system (GPS) to record these paths.The results showed that the walkers were only able to keep a straight line when the sun or moon was visible.As soon as the sun disappeared behind some clouds, people started to walk in circles without even noticing it. Souman said one explanation offered in the past for people walking in circles was that most people have one leg longer or stronger than the other, which would produce a systematic bias in one direction.To test .the researchers asked people to walk straight while blindfolded which removed the effects of vision.They found that these circles were rarely in a systematic direction, with the same person sometimes switching to the left and sometimes to the right. "Most of the participants in the study walked in circles, sometimes in extremely small ones.Walking in circles is therefore not caused by differences in leg length or strength, but more likely the result of increasing uncertainty about where straight ahead is," said Souman, "Small random errors in the various sensory signals that provide information about walking direction add up over time, making what a person perceives to be straight ahead drift away from the true straight ahead direction." Question: What is the probable reason for people's walking in circles? Yes or no, is the answer "The increasing uncertainty about directions."?
(Answer)
No

Article: People smile at times. However, the meaning of a smile in different cultures may be different. Depending on different cultures, smiling can express joy and amusement, but it can also show embarrassment . People in the United States smile a lot. Every one smiles at each other in order to show they are open and friendly. However, in China, smiling is not only an expression of happiness, but also a way to avoid being embarrassed. Chinese people like smiling when they are embarrassed in order to avoid embarrassment. Smiling is a kind of good will but not sneer . For example: When a child falls down from a bike, the adults in China may smile, which is a kind of gentle encouragement and not a kind of impolite laugh. When a person from the United States might blush with embarrassment or become offensive , a Chinese might blush with smile. To avoid serious misunderstanding, people who engage in intercultural communication should be able to understand the meaning of smiling properly. Question: What is mainly talked about in the passage? Yes or no, is the answer "Smiling can express different feelings depending on different cultures."?
(Answer)
Yes
