What do astronauts eat in space, and why? How did astronaut food come into being? How do astronauts preserve food for long periods of time in space? NASA(the National Aeronautics and Space Administration) has been researching food for space travel since the 1960's to find the best way of keeping astronauts from going hungry. The research could date from an accident that took place on the first manned Gemini mission in 1965. astronaut John Young managed to sneak a corned beef sandwich onto the Geminni III capsule to eat during its orbit around Earth. To Young's surprise, the sandwich plan did not go as expected; instead the sandwich began to break apart and scatter through the Geminni IIIcapsule. This could have resulted in disaster, since a small piece of food could have stuck in the air vents and other equipment. The sandwich was stuffed into a pocket to avoid the further mess inside the small space capsule This incident caused NASA to enforce strict rules on what types of food can be taken into space. Space food has come a long way since then. During the Gemini period, the astronauts mostly ate cubed, compressed foods high in calories and lightweight. NASA expects a long shelf life for space food. The majority of food taken into space has been dried out or heat-treated. These process and use of sodium , make the food taken into space last longer. Research is ongoing into space food to seek out healthier ways to preserve it. Too much sodium is unhealthy, and can badly change the taste of some foods. What is the text mainly about? A) How to make space food B) The history of space food C) A food incident in the Gemini capsule D) The process of making space food

(CNN)-China will sometimes say "no" and the world should get used to it. That message came through when China joined Russia in blocking action on Syria. "Do not mistakenly think that because China takes a careful and responsible position on the Syria issue, China will not use its veto power or will always abstain ," said Cui Tiankai, China's vice foreign minister, "When China must use its veto power to say no, it will surely use it." On Saturday, Susan Rice, the U.S. ambassador to the United Nations, called the vetoes "disgusting and shameful." He Wenping, director of African Studies at the Chinese Academy of Social Sciences, said the veto shows China's confidence in foreign affairs. "A country expressing its true opinion - that's progress. China opposes the use of threat or force to achieve regime change in other countries. This agrees with China's long-standing diplomacy principle. It is also not acceptable for China to rush a U.N. vote without sufficient discussion." So why did China use its veto this time? China's critics say China's veto of the U.N. draft proposal was in part due to Beijing's fear that allowing a regime change in Syria could encourage the spread of the Arab revolution and eventually threaten China. He Wenping disagrees, "China has a completely different political system and economic development path. If someone in the international community thinks that the Arab Spring will happen in China, then I think they misjudge the situation in China, exaggerate some problems in the Chinese society and underestimate the ability of the Chinese government to control the situation in China." Which of the following is TRUE according to the passage? A) China often uses its veto power on international issues. B) China never uses its veto power on international issues. C) China's normal practice in the U.N. is to abstain rather than veto. D) China should not have veto power in the U.N.

Q: To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount.That is according to a study published this Monday in the Public Library of Science Medicine Journal. After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't. "We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, "said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council."The benefit was also seen regardless of whether or not people were fat and what social class they came from." Study participants scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake. Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes.But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years. "We can't say that any person could gain 14 years by doing these things, "said Dr.Tim Armstrong, a physical activity expert at the World Health Organization."The 14 years is an average across the population of what's theoretically possible." "Most people know that things like a good diet matter and that smoking isn't good for them, "Susan Jebb said."We need to work on providing people with much more practical support to help them change." We can learn from the passage that _ . A) Susan Jebb did not take part in the study. B) the study observed people as well as tested specific changes. C) there's no need for people under 45 to adopt these good habits. D) only those from first class can benefit from these healthy behaviors.
