Why do Chinese like drinking hot water?
In Western countries, drinking hot water isn't common. 1.
2..A British man, who has been in Beijing for over five years, visited local cafe during his trip in England. He said to a friendly waitress in a classy British accent, “Can I have a glass of hot water, please?” The waitress' eyes widened. She was so confused. “To...to...to drink?” she replied. Eventually, the man received the steaming liquid but felt cold stares from every corner of the cafe. Westerners are as curious about why Chinese people drink hot water as Chinese are curious about why Westerners drink cold water.
This cultural difference is not a simple issue, but related to history, culture, and science. When did Chinese start to drink hot water?3.. Archaeologists found pottery dating to 20,000 years ago. They believe the pottery was used to cook food and heat water.
Drinking hot water is considered to be healthier among Chinese people.4. Bodies’ normal temperature is 37℃, which keeps the smooth flow of blood cycle and the regular operation of the body's organs. Cold water has the effect of slowing.
5.If the body is too weak to warm up, some syndromes（症状）may present themselves, like cold hands and feet, Raynaud's phenomenon(the fingers turning white after exposure to low temperature or emotional events),a weak desire to eat food, poor digestion or body pain.
A. The answer lies in history.
B. There is a story online.
C. It is easy to provide an accurate answer.
D. Westerners often drink with ice almost every day.
E. Drinking cold water leads to an imbalance of temperature inside a body.
F. Hot water was reserved for the pregnant women, the elderly and the sick.
G. When drinking cold water, you will consume more energy to warm up.
Scientists have recently discovered a major habitat where live more than 1.5 million Adelie penguins(企鹅）near the Antarctic Peninsula. Based on direct ground counts and computer counts, the researchers found a total of 751,527 pairs of Adelie penguins on the Danger Islands in the Weddell Sea on the east side of the Antarctic Peninsula. The Adelie penguins discovered here is more than the rest in the other places of Antarctic Peninsula, which was published in the journal Scientific Reports.
Moreover, the number represents the first complete census of Adelie penguins in the Danger Islands, the researchers added. “Until recently, the Danger Islands wasn't known to be an important penguin habitat.” Heather Lynch, an ecologist from Stony Brook University who led the study, said, “These super habitats have gone undiscovered for decades partly because the islands themselves are distant and the dangerous waters that surround them.” The Danger Islands appears to have avoided recent loss in penguin population documented on other parts of the Antarctic Peninsula.
Another study published earlier suggested that more than 70 percent of king penguins may disappear by the end of the century as a result of global warming and overfishing. As the Danger Islands is likely to remain important islands for many penguins under climate change, scientists believe it deserves special consideration in the design of Marine Protected Areas in this area. “Now that we know how important this area is for penguin, we can better move forward designing Marine Protected Areas and managing the fishery,” said Lynch.
The idea of building the Marine Protected Areas, which covers 1.8 million square km of the Weddell Sea and around the Antarctic Peninsula, was first put forward by the European Union and supported by nongovernmental organization Greenpeace. In January, a global campaign has been started in the vast fishing-free zone to better protect wildlife.

Something makes your throat strange. It night be a piece of dust or some food that went down your breathing tube by mistake or mucus(黏液）that dropped down from your nose. You cough.
Sometimes you cough on purpose because you want to clear your throat. Other times you don't have to cough. Cough are useful. They clear your main breathing tube, the same way you clear a straw when you blow through it.
If you have mucus or dust or food in your throat, a cough will help to clear it out. But if you have an infection, a cough won't make it go away. That's why, sometimes, you keep coughing. If you do a lot of coughing, your stomach and chest muscles might ache from extra exercise.
Every cough happens in the same way: Firstly, you take a breath so that you have air in your lungs. Secondly, you close your throat and tighten up some of the muscles in your chest, getting them ready for the big push.
Coughs make an exploding sound because of the air that is pushed out of your lungs through closed lips in the back of your throat. These vocal cords(声带)are forced open by the air causing the explosion that we call a cough. They are the same vocal cords that make the noise when you sing or talk; you sound like you because of your vocal cords.
You can tell who is talking by the sound of a person's voice, but it's hard to tell who is coughing by the sound of the cough. People with high voices sometimes have low coughs. People with low voices sometimes have high coughs. That's because the sound of a cough depends upon how much air is blown out and whether or not the vocal cords are swollen from an infection.

I am Duncan Bannatyne. I am a successful businessman with a chain of health clubs and hotels.I also appears on the BBC series Dragons Den,where I judge new business ideas. The only thing I enjoyed at school was maths. I had the ability to add up, but my maths teacher didn't have much time for me because I couldn't write down how I got the answers. I hated things like English-I slightly had difficulty in reading. I was hopeless at sport, too. I could see that the kids who went to high school had better toys than me so I made up my mind to do as well as I could, so that I could pass the exam and get into the best school. I worked very hard, and then I made it. I was the only one in the family who did, so my parents were so proud of me.
I started delivering newspapers when my mother said I couldn't have an ice cream because we were too poor. When I went to the newsagent's (报纸杂志店)，the owner told me that there was no need for a delivery boy. I said that my mother would like her paper delivered. But he told me, “That's one person. I need 100.”At last, I knocked on 150 doors. When the ice cream van(箱式货车)came around again, I had enough money to buy ice creams for my whole family.
When I left school, I didn't use my business skills for fifteen years. I was in the Navy and then worked as a garage mechanic. It was always in my mind, though. When I was twenty nine, I was on a beach in the Channel Islands with my girlfriend and we decided to go back to the mainland and make money. Believe it or not, my first company was Duncan's Super Ices which expanded from a single ice cream van to a large group of ice cream vans.
