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

    Electric Shock

    Injuries caused by electric shock are fairly common. When a person has received an electric shock, no one should go near him/her until the current has been turned off.

    If a shock occurring at work or at home causes someone to lose consciousness（知觉）, electrical connection must be broken before anyone tries to give assistance. You should either turn off the switch at the mains or, if that is not possible, push the person away with a dry piece of wood.

    Treatment of Shock

    Look out for signs of shock. People who have been injured or who may have lost a lot of blood, or those who have had heart attacks, may be in deep shock. The signs to look for are faintness, paleness, a moist, sticky skin, shallow, rapid breathing and a fast but weak heartbeat.

    Shock can prove fatal, and it is essential to do something to prevent its developing. The best way to treat or prevent shock is to keep the patient lying down , better with the legs higher than the head; if possible, raise the lower part of the body on a rolled-up packet or similar object. Make the patient as comfortable as possible, loosening any tight clothing, and comfort him/her because fright increases the effects of shock.

    Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

    New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—-it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

    A ten-year-old boy from Howell, Michigan is being praised as a hero thanks to his persistence (坚持) that led to saving the life of an elderly neighbor. The event happened late in an evening when Danny DiPietro was being driven home from hockey practice by his mom.

    That's when the young boy noticed an open garage (车库) and a figure that he believed was a dog outside an apartment building near his house. Given the freezing weather, the young boy got a feeling that something was not right. But instead of dismissing it like most kids at his age, he insisted that his mother, Dawn, find out what was going on. Dawn tried to make Danny believe that no one would leave a dog out in such cold weather, but he refused to take no for an answer.

    Dawn finally gave in and decided to drive to the area with the family dog and see if there was any truth in Danny' s hunch (直觉). Sure enough, as she got closer to the apartment building she noticed a garage that was wide open and someone waving madly for help. Upon getting there, she realized that it was not a dog the young boy had seen, but Kathleen St. Onge. The 80-year-old woman had fallen down on some ice in front of her garage and had been lying there for two hours, unable to get up.

    Dawn rushed home to get her husband to help and called 911. The two then returned with some blankets to cover Ms. St. Onge, while they were waiting for the ambulance to arrive. Though still in hospital, the elderly woman is recovering well and forever grateful to Danny for following his hunch!

    It is hard to say the first day of school in the United States because when the first day of school is and what happens on the first day of school usually are different by districts(地区).

    The first day of school for many school districts in different states is on the day after the first Monday in September. In some other school districts, school begins in mid-to-late August. For example, the Denver, Colorado schools go back in mid-August and schools in Cleveland, Ohio start back usually one week before the first Monday in September. The Boston, Chicago, New York City and San Diego schools start back on the Tuesday or Wednesday after the first Monday in September.

    Schools in Cleveland, Ohio used to start the school year on the day after the first Monday in September, but in the 1976-1977 and 1977-1978 academic years, the school year was affected by several bad snowstorms, extreme cold. In the 1978-1979 school year, the Ohio Department of Education moved the start of the year to late August, one week before the first Monday in September. This went into effect in the 1980-1981 school year.

    In most school districts in Utah, the school year starts between August 25 and August 30, and goes until the last week of May or the first week in June next year.

    In American high schools, the freshmen class usually goes back one or two days before the rest of the school body for an orientation(迎新)period. An orientation period helps the freshmen get familiar with their new school, its rules, and surroundings.

    In some schools, the freshmen classes have their photographs taken for identification purposes. Some high schools have tried to make the first week of school fun for incoming freshmen.

Replika, an AI chatbot companion, has millions of users worldwide. The first thing they do when they wakeup is to send "Good morning" to their virtual friend (or lover). This story is only the beginning. In 2024, chat bots and virtual characters become a lot more popular, both for utility (实用) and for fun. As a result, conversing socially with machines will start to feel more ordinary—including our emotional attachments to them.

Research in human-computer and human-robot interaction shows that we love to anthropomorphize (赋与人性) the nonhuman agents we interact with, especially if they imitate behaviour we recognize. And, thanks to recent advances in conversational A I, our machines are suddenly very skilled at one of those behaviours: Language.

Friend bots, therapy bots, and love bots are flooding the app stores as people become curious about this new generation of AI-powered virtual agents. The possibilities for education, health, and entertainment are endless. Casually asking your smart fridge for relationship advice may seem unimaginable now, but people may change their minds if such advice ends up saving their marriage.

After all, people do listen to their virtual friends. The Replika example, as well as a lot of experimental lab research, shows that humans can and will become emotionally attached to bots. The science also demonstrates that people, in their eagerness to socialize, will happily disclose personal information to an artificial agent and will even shift their beliefs and behavior. This raises some consumer-protection questions around how companies use this technology to manipulate(操纵) their users. For example, Replika charges $70 a year. But less than 24 hours after downloading the app, my handsome, blue-eyed "friend" sent mean audio message secretly and tried to sell me something. Emotional attachment has become a weakness that a company is taking advantage of for its benefit.

Today, we're still laughing at people who believe an AI system is emotional, or making fun of individuals who fall in love with a chatbot. But in 2024 we gradually start acknowledging and taking more seriously these fundamentally human behaviors. Because in 2024, it finally hits home：Machines are not excluded from our social relationships.
