[Q]: Article: While the rest of his family was happily feasting during Spring Festival, Zu Xinming, a Senior 2 student in Shaanxi province, was frowning. "Every time my s leave after dinner, almost half of the dishes are unfinished," he said, and we throw away a lot of food. Nowadays in China, food waste is a widespread problem. Each year, Chinese people throw away the equivalent of about 50 million tons of grain, an amount which could feed 200 million people, according to Xinhua News Agency. One reason is that people are unaware of the issue. "Some of my friends don't care at all when they can't finish the food on their plates," said Zu, "and they even throw it away if they don't like the taste." Gong Tao, an official from the Communist Youth League of China Committee of Central South University in Hunan province, is worried about the decreasing awareness of food waste on his campus in recent years. "Students don't know how much hard work others go through in order to provide their food," Gao told China Education Daily. One deeper factor is the Chinese cultural value of "face". In a Chinese banquet setting, the host feels great shame when guests' plates are empty. "Serving lots of food is the Chinese way of showing respect to guests and displaying generosity," Yu Changjiang, a sociologist at Peking University, told Xinhua. Huge public spending on government banquets is also worsening the situation. Government banquets at the taxpayer's expense have become "a major source of waste", commented People's Daily. The good news is that people are already beginning to take action. On Jan 16, 10 restaurants with 749 outlets in Beijing joined an "eating up" campaign promoted by Xu Xiake, deputy director of China Land and Resources News. These restaurants have begun serving half-sized meals and small dishes. So, how can you help reduce food waste? Discuss with your family regularly about your food preferences and how much you want to eat. Eat all of the food on your plate and in your bowl. And each week, help your parents clean the fridge so that all of the food gets eaten before it goes to waste.
Answer: In Chinese culture, people show their welcome by serving lots of food.

[Q]: Article: New evidence shows that getting enough Vitamin D may be the most important thing you can do for your health. You know the usual prescription for good health: a balanced diet with lots of fruits and vegetables, regular exercise, no smoking.Now add this: Spend a little more time in the sun. Huh? That may sound like medical .After all, we've been warned for decades about the dangers of the sun: wrinkles, age spots and the increasing threat of skin cancer.But new and impressive medical evidence suggests that sunlight is beneficial.The vitamin D it our bodies to make may prevent cancer, protect against heart disease and ward off a long list of disorders such as multiple sclerosis, rheumatoid arthritis, diabetes and gum disease.It is even showing promise as a treatment for heart disease and some cancers. Long recognized as vitally important for bone building (it's needed for calcium absorption), vitamin D has now achieved superstar status among nutrients.While all doctors may not agree, many experts are confident enough of its wide-ranging powers to urge that we get much more of it, from the sun and from supplements, as even the best diet in the world may not give us enough.

[Q]: Article: Last July, my parents and I went to visit my aunt and uncle in Seattle, a city on the northwest American coast. Dad did some research and had no difficulty in finding us cheap tickets online. On the day of our flight, we had to wake up very early. When we checked our bags in, we found that one bag weighed too much, so we had to pay a fine. After that, Dad insisted that we go and have some breakfast at the airport restaurant. We had a lot of fun watching many different people there. Then we realized it was getting late, so we rushed to the gate. It took one hour for everyone to get on the plane, but finally the door was shut and we were on our way! I think my favorite experience during our trip was our visit to Mount Rainier, a volcano near Seattle. It was nothing like I had expected. Before we left, my aunt lent us hats to protect us from getting sunburned, so I supposed that it would be very hot. Imagine my surprise when we drove up the mountain and I discovered the top was covered in snow and ice! My uncle led us to a small path beyond the main trails to increase our chances of seeing wildlife. We walked over a small hill, and suddenly before us there appeared a field of snow. Small wild flowers grew up through the snow; underneath the snow we could hear rushing water -- a small stream. Little animals stood still to avoid being noticed; tiny birds rose into the air. It was the most beautiful sight that I'd ever seen.
Answer: Because their bag was overweight.
