[Q]: Article: On Jan 23, 2012, I was aboard a ship on the Yangtze River, listening to the sound of fireworks and eating plate after plate of dumplings. On Sunday Feb 10, 2013, I was preparing to celebrate Chinese New Year again - in London's Chinatown. It was raining. It was cold. But ever since I left Beijing in August, I had promised myself I would celebrate Chinese New Year - if only to help with my Beijing "homesickness". Central London was dressed up for the occasion. There was a stage for a big fireworks display for the evening. Even so, it wasn't like my real Beijing chunjie. Even buying a baozi didn't cheer me up. It cost about 10 times as much as the real thing does in Beijing and got stuck to its rain-ruined paper bag. Cold, wet and depressed, I ran into a shop for shelter. Suddenly, there it was. Between the packets of dried meat and fish, the bags of rice and the smell of dried noodles in this little Chinese supermarket, I had found home. An hour later, I hurried into my house with bags of frozen jiaozi, packets of sauce and a large bottle of vinegar. I boiled water, tore open the packets, grabbed my chopsticks and settled down to a feast. This, I thought, is a Happy Chinese New Year. I even watched the fireworks on TV. After all, why face the British weather when I can bring China home in one bite?
Answer: very depressed

[Q]: Article: How would you like to brush a crocodile's teeth? Or give a shark a bath? Cats are well-known for the way they keep themselves clean by licking , but other animals have their own ways to stay clean as well. And tidiness can be important for their survival. Even cockroaches have to keep their feelers clean to help them into food. Many animals in the wild, such as deer, wolves and bears, have an automatic cleaning system. Insects like to attach themselves to animals to feed on the skin or blood. These parasites can be unhealthy. But their "host" animals are constantly dropping skin and fur by a natural process. They also like to rub up against trees or rocks to comfort themselves, and this removes additional skin and fur. Along with old fur goes the dirt and parasites living in the fur. While these animals may sometimes take a bath when they enter or cross a river or lake, they don't need the water to stay clean. They don't get sweaty, because they don't have sweat glands all over their bodies the way people do. Growing new skin and fur is enough to keep them clean. Some animals and birds use dust to get clean. Chinchillas, a kind of small animal that lives in the mountains of South America, have a very fine fur. (They are raised for their fur, in fact.) If they took water baths, they might get too cold. So, instead, they roll around in fine dust, raising quite a cloud as they "bathe". The dust helps to keep their fur and skin dry. This protects them from bacteria and parasites that enjoy warm and wet places. And the fine dust doesn't stick in their fur for long. It falls off or blows away. As for lions and tigers, their rough tongues act like combs and can remove dirt and loose fur. Why is it important for them to stay clean and smooth? It helps them stay cool in very hot summer or feel warm in cold winter.
Answer: For animals, cleanliness is a survival skill.
