[Q]: Article: It is a reply to a letter written by Zhai Mingjun, a 16-year-old girl in the class. The two astronauts thank the student for her concerns and wish the class luck in their future studies. "I' m so happy that the two space men replied with a few encouraging words," said Zhai. Her letter was one of the 10 winning letters taken into space by Fei and Nie, who have succeeded in traveling space in the Sixth Shenzhou Spaceship. Zhai wrote the letter as if she were a younger sister of the astronauts. "As the single child in my family, I always hoped that I would have an elder brother that I could be proud of," Zhai said. "I thought that the astronauts would be lonely during such a long space trip. I hoped they would feel happy and warm when reading my letter." Many of Zhai' s classmates also wrote their words of encouragement and admiration to the astronauts. "The letter to the astronauts made us believe that we can also be part of the manned space programme," said Zhao Dongxu. All the students have high expectations for China' s future space programme. "I heard that Snoopy is the mascot for US astronauts. I hope I can design a mascot for our heroes," said Liu Mengjie, 16. "A physics class taught by astronauts in outer space would be very interesting. I want to be the astronaut who teaches students about zero gravity with my head upside down in the spaceship," said Han Yinan. Many students think that the manned space program is still far away from them. But they feel proud that ordinary students could participate in such a great scientific achievement and hope there will be more possibilities to take part.
Question: The best title of this passage can be _ .

[Q]: Article: A young man approached the foreman of a logging crew and asked for a job. "That depends," replied the foreman. "Let's see you fell this tree." The young man stepped forward and skillfully felled a great tree. Impressed, the foreman said, "You can start Monday." Monday, Tuesday, Wednesday, Thursday went by -- and on Thursday afternoon the foreman approached the young man and said, "You can pick up your wages on the way out today." Shocked, the young man replied, "I thought you would pay me on Friday." "Normally we do," said the foreman. "But we're letting you go today because you've fallen behind. Our daily felling charts show that you've dropped from first place on Monday to the last place today." "But I'm quite hardworking," the young man disagreed. "I am the first to arrive and the last to leave and even have worked through my coffee breaks!" The foreman thought for a minute and then asked "Have you sharpened your axe?" The young man replied, "No, sir. I've been working too hard to take time for that!" Our lives are like that. We sometimes get so busy that we don't take time to "sharpen" the axe. In today's world it seems that everyone is busier than ever, but less happy than ever. Why is that? Could it be that we have forgotten how to stay sharp? There's nothing wrong with hard work. But we shouldn't get so busy that we ignore the truly important things in life. We all need time to relax, to think, to learn and to grow. If we don't take time to sharpen the axe, we will become dull and lose our effectiveness.

[Q]: Article: Outdoor air pollution leads to more than 3 million premature deaths each year, and more than two thirds of them occur in China and India, according to new research. The authors estimate that without government intervention, the total number of deaths could double by 2050. The study, published in the journal Nature, identifies particulate matter as the prime pollutant leading to premature mortality. Particulate matter, a substance formed as a combination of different materials released into the air, is thought to be harmful to human health once it exceeds 2.5 micrometers in diameter. Researchers also identified ozone as a contributor to dangerous air quality. The causes of air pollution vary dramatically from place to place. In India and China, the study says, emissions from residential heating and cooking drive air pollution by creating unhealthy quantities of smoke. Overall, residential heating emissions cause one third of air pollution-related deaths worldwide. In highly regulated areas, like the United States, Europe and Japan, emissions from agriculture tend to be primary contributors to air pollution. Fertilizer used in agriculture releases ammonia into the atmosphere, a process that creates harmful particulate matter. Globally, air pollution from agriculture kills more than 600,000 people annually, the study finds. The findings are consistent with a 2014 report from the World Health Organization that suggested that 7 million deaths occur annually due to both indoor and outdoor air pollution. The study's conclusions give a sense of urgency to efforts to reduce air pollution but present challenges because of difficulty regulating heating activity in people's homes, according to study author Jos Lelieveld. People who live in the most affected areas should be provided with information about less toxic heating methods, he said. "It's important to reduce emissions from residential energy use," Lelieveld said on a conference call for journalists. "You can't ask people to stop eating and cooking, but you can provide better technologies." Air pollution contributes to a variety of ailments that eventually lead to premature mortality like lung cancer, stroke and heart failure, according to the study. Another study published this week in the journal Environmental Health Perspectives reached similar conclusions showing the devastating effects of pollution on individual health. Researchers found that chronic exposure to particulate matter increases the chance of early death by 3%. That risk is especially high for heart disease; the chance a person will die of heart disease increases by around 10% with chronic exposure to particulate matter. Researchers found that the number of deaths is expected to double by 2050 without new government policies. Nearly all of the increase will occur in Asia, according to the report.
