There's no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there's little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?

    You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.

    So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?

    The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.

    The truth is, there is no magic standard for hydration—everyone's need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you'll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you're thirsty.

    Slowly, so slowly that we never even noticed how it happened, our family stopped talking to each other. Our own worlds opened up to us through the computer or the cell phone or the CD player.

    Family Night was born when Mom called us for dinner. Jessica and I came and sat down. Dad loaded his plate and started to rise from the table.

    “Where are you going?” Mom questioned.

    “To the living room. I have some work,” Dad replied as he hurried away. Mom's face got tight, but she said nothing. About two minutes later, my cell phone buzzed. Jessica kept her earphones on during most of the meal. Mom was clearly upset.

    Family Night started the next week. Mom established three rules: no phones, no music, and no leaving the table. Everyone would eat together and play a game together “like a real family.”

    All seemed to be going according to Mom's plan until the first buzz of a cell phone. After dinner, we had been playing the board game for only ten minutes when another cell phone let out a shrill scream. This time the phone belonged to my father.

    “Work's calling. I have to answer,” he whispered as he hurried out of the room.

    Mom sighed, but she forced a smile and encouraged us to continue with the game. We kept playing through every interruption afterwards: the beeping of Jessica's phone, the buzz of another text message from Darnell, the soothing voice announcing the arrival of an e-mail on Dad's computer. When the game was over, Mom released us to our rooms.

    That first Family Night was not a success, but Mom soldiered on. Every Monday evening we silenced our electronics and gathered around the table; and each time, setting aside our technological toys became a little easier. The next two months my father would be taking business trips. We wouldn't be able to have Family Night every Monday.

    To my surprise I realized that I would miss those few hours each week when the house was filled with my family's laughter and conversation. I was also glad to know that when we really wanted to, we could silence the electronic buzz and just be a family again.

    From ancient stories to modern researches, the label（标签）attached to being left-handed is undeniable. Left-handed people, or "lefties" as they are often called, are generally believed to be good at art — Leonardo da Vinci, Picasso and Michelangelo are all left-handed.

    Our brain is divided into two parts: the left hemisphere(大脑半球)and the right hemisphere. The left hemisphere, linked to logic and analysis, is responsible for the right side of the body. The right hemisphere, linked to creativity and imagination, controls the left side of the body. So, people tend to believe lefties are controlled by the right side of the brain, and are more creative than right-handers. Some also think that lefties may not be as good as right-handers in mathematics and problem-solving skills.

    However; a recent study carried out by scientists from the University of Liverpool in the UK and the University of Milan in Italy proved this theory wrong. The study involved(涉及)more than 2,300 students in Italy aged between 6 and 17 years old. They were asked to complete several mathematical tasks of different levels. It turned out the left-handers outperformed the others when the tasks involved difficult problem-solving. This pattern was particularly clear in male adolescents. However; when it came to simple arithmetic, there was no difference between left-handers and right-handers.

    It was also discovered that those who are "severely" right-handed performed less well in all the experiments compared to "medium" right-handers and left-handers.

    "Taken together, these findings show that handedness does influence abilities to some degree," the study's authors wrote. However, "handedness is just an indirect expression of brain function," wrote psychology professor Giovanni Sala from the University of Liverpool in the UK, the lead author of the study. Sala also noted that only one third of people with a highly-developed right side of the brain are left-handed. It means that there are lots of right-handed people with a similar brain function as left-handers.

    There is an old saying that America and Britain are "two nations divided by a common language." No one knows exactly who said this, but it reflects the way many Brits feel about American English. But are American and British English really so different?

    Vocabulary

    The most obvious difference between American and British English is vocabulary. There are hundreds of everyday words that are different. For example, Americans go on vacation while Brits go on holidays; New Yorkers live in apartments while Londoners live in flats. There are far more examples than we can talk about here. Fortunately, most Americans and Brits can usually guess the meaning through the context of a sentence.

    Past Tense Verbs

    You'll also find some differences with past forms of irregular verbs. The past tense of "learn" in American English is "learned". British English has the option of "learned" or "learnt". The same rule applies to "dreamed" and "dreamt", "burned" and "burnt", and "leaned" and "leant". Americans tend to use the -ed ending; Brits tend to use the-t ending.

    Spelling

    There are hundreds of slight spelling differences between British and American English. Noah Webster, an author, politician and teacher, made an effort to reform English spelling in the late 1700s.

    Webster wanted to spell words the way they sounded. You can see Webster's legacy(遗产) in the American spelling of words like color (from colour), honor (from honour), and labor(from labour).

    Not So Different After All

    British and American English have far more similarities than differences. With the exception of some regional dialects, most Brits and Americans can understand each other without too much difficulty. They watch each other's TV shows, sing each other's songs and read each other's books. They even make fun of each others' accents.

At a snow park in Zhangiakou, Hebei, Chinese teenage snowboarder Su Yiming won a silver in the men's snowboarding competition on February 7, 2022. It was the first time that a Chinese snow boarder had ever competed in this event at any Olympics. 

Su was introduced to snowboarding at the age of 4 by his parents who were both snowboarding fans. Su fell in love with the sport the first time they took him to a ski center. Later he kept on practicing after class. To save up more time for snowboarding, he would get up at 5 a. m. and finish his homework early. Su just saw snowboarding as a hobby in the beginning. However, on July 31, 2015, when he knew that 2022 Winter Olympics would be held in Beijing, his mind tuned to professional (职业性的) competition. He dreamed of joining in the Winter Olympics. And he decided to go professional. 

In 2018. Su became a member of China's national snowboarding team. In 2020 and 2021, he took home gold medals (奖牌) in all national competitions. In January 2021, he became the first Chinese male snowboarder to finish the Cab 1800-one of the most difficult snowboarding skills. 

Behind his success is Su's hard work. He has made full use of every chance to train more. Usually he arrived at the training center earlier than his teammates. In that way, he could practice more. He even broke several snowboards in one week because of heavy training.
