Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli , “it has to be so much better that it replaces what we have already.” The Internet is one example --what will be the next?

    Deborah Cohen is a senior natural scientist at the Rand Corp and the author of the book A Big Fat Crisis: The Hidden Forces Behind the Obesity Epidemic and How We Can End It. According to the book, there are lots of misunderstandings of obesity.

1).If you're obese, blame your genes.

    Obesity rates have increased. Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible.

    At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2).If you're obese, you lack self-control.

    Research shows that if we are faced with too much information, we have a tendency to make poor dietary choices. Our world has become so rich in temptation that we can be led to consume too much in ways we can't understand. Even the most vigilant (警觉的) people may not be up to the task of controlling themselves.

3).Lack of access to fresh fruits and vegetables is responsible for obesity.

    Although the US Department of Agriculture estimates that fewer than 5 percent of Americans live in the “food deserts”, about 65 percent of the nation's population is overweight or obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4).The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. But there was no significant decrease in physical activity levels as obesity rates climbed in the 1980s and 1990s. In fact, although a drop in work-related physical activity may account for up to 100 fewer calories burned, leisure physical activity appears to have increased. The problem is that we eat too much.

    Spend any time in London, England's capital, and you'll quickly gather that it's a multicultural (多元文化的) community. Look around at your fellow passengers on the Tube(地铁) or the bus. They're of every skin color and dress differently to one another. Listen, and you'll hear many other languages besides English spoken. Some of these people, no doubt, will be tourists who are in London to see the sights. But others — in fact probably most — will be living their lives there, along with millions of others.

    Along with white British people, there are Britons from, or with parents and grandparents from, the Caribbean, India, China and most other places. This makes London a fascinating place in which to live. The reason is that when people settle in a place, they don't just buy a house and live there, but bring aspects of the culture of their “old country” with them.

    The most visible sign of this is the number of restaurants offering dishes from different parts of the world. In a city in which it's estimated 250 different languages are spoken, you can expect a similarly wide range of foods to be available. You would expect in one of the world's leading cities to encounter(遇到) French, Italian, Chinese and Indian eateries. But in London you'll also find Polish, Patagonian and Palestinian restaurants.

    However, London's multiculturalism isn't just about food. Many types of people are gathered in one space, but the way they live differently shows in that space. They worship(崇拜) differently, for one thing. Alongside the famous old English churches by Nicholas Hawksmoor and Christopher Wren — responsible for one of the capital's most famous landmark, St Paul's Cathedral—you'll find mosques(清真寺), temples and synagogues (犹太教堂).

    London even speaks its own special kind of English. Language experts created the term “Multicultural London English” to identify the dialect of English that appeared at the end of the last century.

    All of this makes London a very surprising and varied place to call your home. But, in a way, this has long been true. In the 18^th century, the compiler(编纂者) of the first English dictionary, Samuel Johnson, once said: “ He who is tired of London is tired of life.”

    In the online world, it's very difficult to talk to Chinese people without using emojis. However, did you know that people in different age groups have totally different preferences for choosing their emojis? The result is based on a report released by Tencent's WeChat, China's most popular messaging app, on its official weibo account on Wednesday.

    Specifically, for users who were born in the 2000s, their favorite WeChat emoji would probably be the widely used "facepalm", rumored to be based on the famous Hong Kong movie star Stephen Chow. They also may be a night owl without much sleep, while iced beverages and desserts are their cup of tea.

    For China's post-90s WeChat users, they are likely to get out of bed later in the morning compared with other groups, and the emoji "face with tears of joy" may rule their online social life. Also, their reading materials have shifted from entertainment and gossip three years ago to the current relationship and lifestyle pieces.

    For those born in the 1980s, their tastes have remained the same, as they are still fond of reading news on national affairs. And "smiling widely" is their emoji of the year.

    WeChat users born in the 1970s are called the optimistic group, who like to use the emoji "laughing quietly" and go through their moments frequently every day. Their bed time usually takes place around 11:30 pm.

    Users over 55 are the early-bird group with rich entertainment activities in WeChat platforms, such as looking through moments, reading and shopping. They like to cheer up other age groups, so their favorite emoji is "giving a thumbs-up".

    The report also indicates that WeChat boasts more than 1.08 billion active users with 45 billion messages being sent and 410 million calls getting through the app each day in 2018. In addition to covering users' socializing, WeChat has gradually come into our daily lives. Compared to the year before, people used WeChat 4.7 times more to purchase public transport tickets, and 2.9 times more to pay for medical expenses. Also, the app was used 1.5 times more over the previous year to pay for meals, with Beijing, Guangzhou and Shenzhen ranked as the top three cities in dining purchases through WeChat.

    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.
