As our family are getting ready for the annual holiday of Thanksgiving, which is probably the most important holiday in the U.S because it's celebrated by people of all faiths. I think back to a cold November day more than twenty years ago. It was a day when my husband and I, married just about three months, got stuck on I -89 in Vermont when our car broke down.

    We had just visited my husband's parents in Vermont, and with a huge turkey they gave us slowly thawing (解冻）in the trunk of our old car, we were heading back to our apartment in Boston to celebrate our first Thanksgiving together. Our car broke down half an hour after we got on the highway. And it was raining. Back to then, not everyone had a cell phone, and in those days if you broke down along a lonely stretch of a highway far from the nearest emergency call box in cold November rain, it wasn't fun.

    Fortutiously for us, a van with a bunch of people coming back from a ski trip stopped andasked if we needed help. They gave us a ride to the nearest gas station, from where we could phone my father-in-law and asked him for help. My father-in-law arranged for :he car to be towed (拖引), and drove us all the way to Boston that day.

    So as we sit down to dinner and think of all the things we can be thankful for tonight, I want to say “thank you” to the strangers on I -89 some twenty years ago for giving a young couple a ride when their car with a frozen turkey in the trunk broke down.

    Never underestimate the difference you can make to the lives of others by one small act of kindness. Step forward, reach out and help. This week, reach to someone that might need a lift.

    These days, young people in some English-speaking countries are speaking a strange language, especially when communicating on social media.

    Look at these words chosen by The Washington Post: “David Bowie dying is totes tradge,” and “When Cookie hugged Jamal it made me totes emosh.” Or this sentence: “BAE, let me know if you stay in tonight.”

    What on earth do they mean? Well, “totes” is a short form of “totally”. Similarly, “tradge” means “tragic” and “emosh” means “emotional”. It seems that, for millennials（千禧一代）, typing in this form is not only time-saving but fashionable.

    As you can see, many millennial slangs（俚语）are formed by so-called “totesing”—the systematic abbreviation（缩写）of words. The trend might have started with “totally” becoming “totes”, but it now has spread to many other English words.

    The origins of other millennial slangs are more complex than “totesing”.“Bae”, for example, has been widely used by African-Americans for years. It can be an expression of closeness with one's romantic partner or, like “sweetheart”, for someone without romantic connection. After pop singer Pharrell used the word in his work, “bae” became mainstream.

    Some people might think millennial slangs lower the value of the English language, but Melbourne University linguist（语言学家）Rosey Billington doesn't agree. She says when people are able to use a language in a creative way, they show that they know the language rules well enough to use words differently. Two other linguists, Lauren Spradlin and Taylor Jones, share the same view. The two analysed hundreds of examples of totes-speak and discovered totesing has complex roots.

    It isn't simply an adult version of baby talk, nor a clever way to minimize your word count. Rather, it is a highly organized system that relies on a speaker's mastery of English pronunciation. It is about sounds, follows sound system of English and has strict rules.

    “Hot potato” is a children's game similar to musical chairs (抢座位游戏), in which participants sit in a circle and pass a potato or any other object to others around the circle as quickly as possible.{#blank#}1{#/blank#} This game is popular for entertaining large groups of kids at parties, school, or other events that include children.

    “Hot potato” was originally played with a real potato.{#blank#}2{#/blank#} No single version is the right way to play. Changes can be made to suit nearly any theme and any situation.

    The game of “hot potato” is easy to play with large groups of kids outdoors.

    {#blank#}3{#/blank#} It's common for physical education teachers to play this game with smaller children, using a ball in order to help children improve their catching skills.

    {#blank#}4{#/blank#} Variations, also called passing the potato or passing the pumpkin (南瓜), are great school party ideas. You can easily create a themed version of the game for Halloween. Have children sit in a circle indoors and hand one child a small pumpkin. The teacher can play Halloween music, but he or she should not look at the circle of kids.

    You can create similar versions for Christmas, Valentine's Day, Thanksgiving Day, or a birthday party.{#blank#}5{#/blank#} It is highly suggested that all players receive a small prize for playing, such as a piece of candy, and the winner can be provided with a slightly larger prize.

A. Above all, laughter is the goal.

B. Players can even stand up if space permits.

C. Hot potato isn't limited to outdoors by any means.

D. In fact, hot potato can be adapted to any children's party.

E. But today there are many other versions of hot potato.

F. Of course, that person singing or calling should not watch the game.

G. The aim of the game is not to be the one holding the potato when music stops.

    When thinking about quitting(停止) smoking…

    List all the reasons why you want to quit. Every night before going to bed, repeat one of the reasons 10 times.

Decide positively that you want to quit. Try to avoid（避免 ）negative（负面的） thoughts about how difficult it might be. Develop strong personal reasons as well as your health and responsibility （责任）to others. For example, think of all the time you waste taking cigarette breaks, rushing out to buy a pack, hunting a light, etc. Set a date for quitting — perhaps a special day like your birthday, a holiday. If you smoke heavily at work, quit during your vacation. Make the date holy seriously, and don't let anything change it. Begin to condition yourself physically; start a modest (适当的) exercise; drink more water; get plenty of rest.

    Immediately after quitting...

    The first few days after you quit, spend as much free time as possible in places where smoking is prohibited, e.g. libraries, museums, theatres, department stores, etc.

    Drink large quantities of water and fruit juice. Try to avoid wine, coffee, and other drinks which remind（提醒 ）you of cigarette smoking. Start a conversation with someone instead of a match for a cigarette.

    If you miss the feeling of having a cigarette in your hand, play with something else - a pencil, a pen, a ruler. If you miss having something in your mouth, try a fake (仿制的) cigarette.

New research into a long-lived tree has shown some of the tricks that have helped it survive for thousands of years. The ginkgo(银杏树) is a huge, slow-growing tree with fan-shaped leaves, native to China, but planted in parks and gardens across the world. Some of the largest ginkgoes are said to be more than 3, 000 years old.

In order to discover how these and other trees can live for so long, scientists from the US and China studied 34 healthy ginkgoes of different ages. The team studied growth rings in each tree's trunk(树干), as well as cells(细胞) from the bark, leaves and seeds. They found that 600-year-old trees were just as healthy as 2-year-olds.

To learn more, the team then looked in detail at the DNA of nine trees aged between three and 667 years old. DNA is the chemical in the cells of plants and animals that holds instructions that tell any living thing how to grow and develop-including what to do at different times in its life At the beginning of a tree's life, DNA instructs the cells in a seedling to divide quickly so the tree grows rapidly. The cells also make special chemicals to help the young plant survive difficult situations, such as disease. As most trees grow older, their DNA tells their cells to divide more slowly (so growth slows down) and to make fewer chemical defenses(防御).

Ginkgoes, however, do things differently. The team found that although their growth finally slows, both young and old trees make protective chemicals." The secret is keeping a really healthy defense system," said researcher Richard Dixon." As ginkgoes age, they show no sign of weakening their ability to defend themselves from things like disease. "Other trees that live for a long time may have the same ability.

For all their defenses, though, ginkgoes cannot live forever--they finally meet with deadly accidents such as fire, disease and storms. While they last, however, these leafy trees are some of the most beautiful trees in the world.

Quantum mechanics (量子力学) is a branch of science that studies the smallest particles (粒子) in the universe, like atoms (原子) and even smaller things. It might sound super complex, but let's break it down in simple language.

Imagine you have a small particle, like an atom. In the world of quantum mechanics, these particles don't behave like the things we see in our everyday lives, like balls or cars. Instead, they act kind of like waves and particles at the same time, which is really strange!

One of the most famous ideas in quantum mechanics is the "Uncertainty Principle", raised by physicist Wemer Heisenberg. This principle says that we can't precisely know both the position and the speed of particle at the same time. It's not because our measuring tools are bad; it's because the particles themselves are naturally uncertain.

Another weird thing about quantum mechanics is something called "Entanglement". Imagine you have two particles that are connected in a special way. If you change one of them, the other instantly changes, no matter how far apart they are. It's like they're talking to each other faster than the speed of light, which goes against what we know from everyday experiences.

Quantum mechanics also deals with probabilities. Instead of saying, "This particle will be here at this exact time," scientists say, "There's a certain chance it'll be here, and a certain chance it won't." It's like predicting the weather, but on a super small scale.

In a nutshell, quantum mechanics is a strange and fascinating world where particles act both like waves and particles, where you can't know everything about a particle at once, and where particles can be mysteriously connected no matter how far apart they are. It's a mind-boggling field that challenges our understanding of how the universe works, and even though it's tough to grasp, it's an essential part of modern physics.
