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.

Article: As I was busy working on my work plan in my bedroom, I could hear my four children playing upstairs. Suddenly, I heard the children running down the stairs and shouting, "Freddie, Freddie." _ My three-year old son Freddie was lying on his side on the ground. I cried for my husband Simon to dial 999 and within minutes the air ambulance arrived. They quickly took him in the helicopter. During the flight, Freddie was looking at me and I remember thinking was a good sign, but then his eyes began to roll. As the doctors tried to stabilize him, I couldn't believe what was happening. When we arrived at the hospital in Portsmouth, there were some doctors and nurses waiting for us and they immediately set to work on Freddie. I was hopelessly wishing everything would be alright, but Freddie had broken his skull in two places and blood clots were forming in his brain. He needed surgery , and only a surgeon at another hospital in Bristol could do it. This meant another helicopter ride, but we couldn't go with Freddie because there was no enough space. Simon and I drove the long 130 miles from our home in north Devon in silence. Neither of us dared say what we were thinking, "What if we get there and he's dead?" "Is he going to be brain-damaged?" Freddie was just coming out of surgery when we arrived. The surgeon said it had gone well. When I finally saw him, I hardly recognize my child--he was covered in tubes and there were wires coming out of his head. On the third day, Simon went home to see our three girls and to pick up some clean clothes for us. While he was gone, the pressure in Freddie's brain suddenly increased. He was taken into theater again and this time I fell apart. Luckily, the surgery managed to stabilize Freddie. After almost a week, Freddie was finally woken up. When he opened his eyes, he looked at me. He didn't say anything, but I knew straight away that it was my old Freddie, and that he was going to be alright. Over the next two weeks, his recovery went well. After help with learning to swallow again and encouragement with speaking, he was soon playing with his Gruffalo cards and eating meals by himself. I still don't know how the accident happened, but we got some idea from our girls. Clearly Freddie and Minnie had been sitting on the window ledge, and Freddie must have opened it to look out and fallen 20 feet onto the ground below. The guilt I feel is awful-- for weeks I was full of " if onlys", and we put window locks everywhere. Six months later, although the accident seems a lifetime ago, it has changed me. I feel differently about life now. I've left my job to put my children first. I want to spend every minute with them.

Article: What is it that makes people laugh? More than two thousand years ago the ancient Greek philosopher Aristotle defined jokes as the pleasure that results from a feeling of triumph by showing we're better than someone else in a certain way. According to Aristotle and many other philosophers,all jokes depend mainly on showing _ in another person or group of persons -- that is,putting it clearly,on showing that they are worse off than ourselves. Jokes raise our good opinion of ourselves at someone else's expense. Showing how much better than other people we are is only one reason we like jokes. Someone may also use a joke to express their anger or their cruelty or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a banana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes,especially those involving cruelty,are so popular with certain people. Besides,all jokes depend on our enjoyment of laughing at something that is strange and out of place because it's different from things which are happening around it. The same situation can be either sad or pleasant,depending entirely on how strange and out of place it is. If a girl in a bathing suit falls into a swimming pool,we don't laugh because nothing unusual has happened. But if a man in a smart suit falls in,the situation is at once unusual in a pleasant way and we laugh. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens,and so we laugh.
