Tea drinking was common in China for nearly one thousand years before anyone in Europe had ever heard about tea.People in Britain were much slower in finding out what tea was like, mainly because tea was very expensive. It could not be bought in shops and even those people who could afford to have it sent from Holland did so only because it was a fashionable curiosity. Some of them were not sure how to use it They thought it was a vegetable and tried cooking the leaves Then they served them mixed with butter and salt They soon discovered their mistake but many people used to spread the used tea leaves on bread and give them to their children as sandwiches

    Tea remained scarce and very expensive in England until the ships of the East India Company began to bring it direct from China early in the seventeenth century during the next few years so much tea came into the country that the price fell and many people could afford to buy it

    At the same time people on the Continent were becoming more and more fond of tea until then tea had been drunk without milk in it, but one day a famous French lady named Madame de Sevigne decided to see what tea tasted like when milk was added. She found it so pleasant that she would never again drink it without milk Because she was such a great lady her friends thought they must copy everything she did, so they also drank their tea with milk in it Slowly this habit spread until it reached England and today only very few Britons drink tea without milk

    At first, tea was usually drunk after dinner in the evening No one ever thought of drinking tea in the afternoon until a duchess (公爵夫人) found that a cup of tea and a piece of cake at three or four o'clock stopped her getting“a sinking feeling”as she called it She invited her friends to have this new meal with her and so, tea-time was born

    Have you ever had one of those days when all you wanted to do was read an emotionally powerful story that would cause you to tears? Most of us tend to be attracted by stories that reach us on multiple levels, including sadness. There are plenty of books that make you cry (and sometimes laugh) and that you can really sink your teeth into. Here are four of them.

    ⒈The Kite Runner

    This realistic and moving description of life in Afghanistan accounts for the people who were badly affected by the Taliban. You'll cry as you get to know the familial relationships and cruelty involved, but you'll also get a sense of hope as you quickly read through this appealing novel.

    ⒉The Book Thief

    Let's put it this way: Death itself is the narrator. The story is about a young girl named Liesel who has to live with foster parents during World War II. On the way to her new home, her brother dies, setting the gloomy tone for the story. There is hope, however, when Liesel discovers her love for reading and makes a relationship with a young Jewish man she helps hide from the Nazis.

    ⒊The Fault in Our Stars

    This is probably the most likely book on the list to make you cry, as it records the experiences of teens who are dying from cancer and living their last days in love. Their lifestyle is tragic and disturbing at the same time, as we watch their health worsen. The real tragedy is the love story between the main characters, who know that their romance is fruitless.

    ⒋A Child Called “It”

    Easily one of the saddest stories of abuse in recent decades, A Child Called It is based on the true story of Dave Pelzer, a boy from California who suffered at the hands of his cruel family. The tears will come from both sadness and the inspiration tied to Dave's fight for survival in an environment where he is believed worthless.

    We now think that chocolate is sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it's an ingredient（构成部分）in the main course of a meal. Mexicans make a hot chocolate sauce called Mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.

    Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say "Ugh!" and run away. Workers must first dry and then roast the beans. This removes the bitter taste.

    The word "chocolate" comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.

    When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao, too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.

    In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.

    Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are the chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.

    Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.

    Certain microorganisms(微生物)cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放)poisons that make people sick.

    Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

    Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.

    When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

    Most people recover from food poisoning after a few days of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.

    Allen Cook and his daughter Melissa were renovating(整修) her house, when they found a beautiful, heart-warming love story. "The envelope in the ceiling was old and yellow. It had never been opened, It was unbelievable when my son-in-low started reading it. In the letter she was talking about the baby she was going to have," Allen Cook said.

    The story began in May 4, 1945, the typed letter was written by a woman named Virginia to her husband, Rolf Christoffersen. At the time, he was a sailor in the Norwegian navy. The envelope was marked "return to sender" and never found its way to her husband. Allen's daughter used the Internet to find the phone number of someone named Rolf Christoffersen and gave him a call, leading her to his son in Santa Barbara, California.

    "Someone called me at my office. They just googled my name because I have the same name as my father. Melissa asked me where I grew up and I told her. She told me she had the letter," Christoffersen's son, 66 now, said. The younger Christoffersen wasn't yet born when his mother Virginia wrote the letter, but he said her words were very special to him. His mother, who died six years ago, wrote about her love for her husband.

    "I love you Rolf, as I love the warm sun, and that is what you are for my life, the sun about which everything else revolves around me," she wrote. Seventy-two years later, her words were finally heard by her husband. Christoffersen immediately called his father, who is now 96. And read the letter to him over the phone. "I was so surprised after all these years. I was very emotional," the elder Christoffersen said.

    The long-lost letter was finally received just before Mother's Day; it was another tangible connection to Virginia Christoffersen. "It's Mother's Day and reading her words reminded me just what a wonderful person she was and how much she loved us" her son said, through tears.

At just seven years old, Angelina Tsuboi discovered her passion for innovation. It all began with a simple game she programmed in her Los Angeles public school's Grade 2class. Today , at18, the Grade 12 student's initial curiosity has evolved into a deep-seated desire to use technology to decode (解码) real-world problems. 

In 2021, she co-developed Megaphone, one of her first apps, to tackle unanswered post-class questions and poor communication about events and announcements. Her problem-solving ability kept building from there. 

When she took online CPR classes at the start of the pandemic, she figured it couldn't be just her who was struggling with the steps. So she created an app called CPR Buddy ― a winner in the 2022 Apple Swift Challenge ― which guides users through CPR using vibrations (震动) to regulate breath. After winning the award, Angelina presented her work to Apple CEO Tim Cook, a highlight in her young career, but one she didn't lose her cool over. "There's no point putting people on a pedestal (神坛)," she says. 

The next year, Angelina built an app called Lilac, designed to assist nonEnglish-speaking single parents with resources for housing, job opportunities and translation support. She was inspired by her own experiences as a child of a single mother who immigrated to the US. 

When Angelina decided to pursue pilot training at the age of 16, she was struck by how difficult it was to find financial support, which encouraged her to create yet another app, Pilot Fast Track, which helps those longing to be pilots find scholarships for flight training. 

Looking to the future, besides applying to colleges with great labs, Angelina is exploring the field of aerospace cybersecurity and mechatronics ― combining computer science, electrical engineering and mechanical engineering. 

"There's not enough optimism in the world," she says. "I have also been in situations in my life where I've lost a lot of hope. But in the end, it is a mindset, and there are ways in any situation you're in to make it somewhat better. "
