Ever since it was created 30 years ago, The Simpsons, the longest running prime-time (黄金时段) TV show in the country, has become part of US life. So when TV critics Alan Sepinwall and Matt Zoller Seitz ranked the 100 greatest comedies and dramas broadcast in the US, it came as no surprise that The Simpsons was their top choice.

    This was the show that changed the very concept (概念) of cartoons in Western society. Before it appeared, cartoons were considered a way to learn and have fun, not serious adult entertainment. The Simpsons changed this. The genius (过人之处) of the show is that it has something to offer both adults and children.

    It's a hugely entertaining program that's also full of satire (讽刺) and clever humor. A remark by Chitra Ramaswamy in The Guardian gave a sense of the esteem (敬重) in which The Simpsons is held: “Nothing before or since has matched its capacity to be at once so profoundly (深刻地) clever and so unbelievably stupid.”

    The show's creator Matt Groening, and the brilliant team that work with him, make fun of the US government, social customs, and of course, the idea of family life. But unlike classic US prime-time TV characters, the Simpsons are a dysfunctional (功能失调的) family.

    Bart, the boy, is always in trouble – both at home and at school. That may be in part because of his paternal (父亲的) example. Homer Simpson, perhaps the most iconic character, is a beer-swilling (喝着啤酒的), overweight slob (懒汉) who is normally found in front of the TV. And Marge, Homer's wife and the mother of the family, spends most of her time cooking, cleaning or trying to fix the messes that Bart and Homer make.

    The smartest member of the family is daughter Lisa, who excels (表现卓越) at school but is no goody-goody (讨好卖乖的人): Lisa never misses an opportunity to challenge authority. The youngest member of the family is baby Maggie, who will likely be as much a trouble as her brother and sister when she grows up – if she ever grows up, that is.

    But although the Simpsons are a problem family, viewers are always on their side. One of the reasons the show has remained so popular all these years is that the characters are so likeable. Millions of us identify with (同情) them. They are a working class family struggling to make ends meet. They aren't perfect, but then, who is? And after 30 years, this is still what strikes a chord (引起共鸣) with millions of viewers worldwide.

    Charlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the “thing”.

    He walked to the bedroom. He saw a jacket hanging in the bedroom and went up to it to have a closer look at the “thing”. The moment he touched it, the thing sprang into life. Now Charlie experiences fear like the rest of us but when this creature opened its wings, he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.

    For a moment the next-door neighbours thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.

Eventually Charlie managed to trap the bat in a box and took it to the garden to let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. “Oh, nothing to worry about”, he said casually hoping that the terror could not be seen in his eyes, “it was just a bat.”

    The popular wisdom for years has been that drinking in moderation (适度)—that's one “standard” drink a day for women and two for men-is linked to a lower risk of cardiovascular (心血管的) disease. But recent studies are casting some doubt on that long-held learning. Science now says it depends on your age and drinking habits.

    A 2017 study of nearly 2 million British with no cardiovascular risk found that there was still a modest benefit in moderate drinking, especially for women over 55 who drank five drinks a week. Why that age? Alcohol can influence the substance in the blood in positive ways, experts say, and that's about the age when heart problems begin to occur.

    Also, a 2018 study found that drinking more than 100 grams of alcohol per week—equal to roughly seven standard drinks in the United States or five to six glasses of wine in the UK—increases your risk of death from all causes and in turn lowers your life expectancy. Links were found with different forms of cardiovascular disease, with people who drank more than 100 grams per week having a higher risk of stroke, heart failure.

    Another 2018 study found that consistently drinking a moderate amount of alcohol, within recommended guidelines, had a protective effect on the heart over time. Unstable drinking habits were associated with a higher risk of heart disease, which the authors reflected might indicate broader lifestyle changes, such as poor health or stress. Former drinkers were also at greater risk.

    Overall, however, the latest thinking is that any heart benefit may be outweighed by other health risks, such as high blood pressure, certain cancers and liver damage.

Women who drink are at a higher risk for breast cancer; alcohol contributes about 6% of the overall risk, possibly because it raises certain dangerous hormones in the blood. Drinking can also increase the chance you might develop liver, mouth and oral cancers. One potential reason: Alcohol weakens our immune systems, making us more likely to inflame (发炎)—a driving force behind cancer.

    Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture.

    From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

    Around the world, people change sleep patterns thanks to the start or end of daylight-saving time（夏令时间）. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

    Russia's other late nights and early mornings generally correspond（相一致）to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

    Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

    Similarly, Americans' late nights, late mornings, and longest sleep fall on three-day weekends.

    Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey（冰球）final.

    The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the World Cup.

    It should be made clear that not everyone has a tool to record their sleep patterns; in some of these nations, it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case, the above findings are still striking. If the most health-conscious among us have such deep swings（明显改变）in our sleep levels throughout the year, how much sleep are the rest of us losing?

    In 1800, only three percent of the world's population lived in cities. Only one city — Beijing — had a population of over a million. Most people lived in rural areas, and never saw a city in their lives. In 1900, just a hundred years later, roughly 150 million people lived in cities, and the world's ten largest cities all had populations exceeding one million. By 2000, the number of city dwellers exceeded three billion; and in 2008, the world's population crossed a tipping point — more than half of the people on Earth lived in cities. By 2050, that could increase to over two-thirds. Clearly, humans have become an urban species.

    In the 19th and early 20th centuries, many people viewed cities negatively — crowded, dirty environments full of disease and crime. They feared that as cities got bigger, living conditions would worsen. In recent decades, however, attitudes have changed. Many experts now think urbanization (城市化) is good news, offering solutions to the problems of Earth's growing population.

    Harvard economist Edward Glaeser, author of The Victory of the Cir, is one such person. Glaeser argues that cities are very productive because "the absence of space between people" reduces the cost of transporting goods, people, and ideas. While the flow of goods has always been important to cities, what is most important today is the flow of ideas. Successful cities enable people to learn from each other easily, and attract and reward smart people with higher wages.

    Another urbanization supporter is environmentalist Stewart Brand. Brand believes cities help the environment because they allow haft of the world's population to live on about four percent of the land. This leaves more space for open country, such as farmland. City dwellers also have less impact per person on the environment than people in the countryside. Their roads, sewers, and power lines need fewer resources to build and operate. City apartments require less energy to heat, cool, and light. Most importantly, people in cities drive less so they produce fewer greenhouse gases per person.

    So it's a mistake to see urbanization as evil; it's a natural part of development  The challenge is how to manage the growth.
