In many places, if you do not take your wallet with you, you'll be in trouble. This is especially true in overseas airports when you want to pay for food or gifts. Luckily you can now pay without your wallet in some overseas airports.

    It's announced on Sept 26 that Chinese tourists can use the third party payment Alipay at ten airports across the world. The 10 airports are in Germany, Singapore, South Korea, New Zealand, Thailand and China's Hong Kong, Taiwan and Macao.

Digital wallets like Alipay, WeChat and Apple Pay have brought big changes to our lives.

    In April, CNN reporter Will Ripley spent a day in Beijing without his wallet. "In China's largest cities, you can definitely (肯定地) survive without carrying a pocket full of money and credit cards — as long as you've got your smart-phone," he wrote. "From small shops to large stores, a huge number of businesses in Beijing accept mobile payments."

    He paid for breakfast by scanning (扫描) a QR code on the window of a restaurant. All he had to do was enter a password.

    Then he also used his phone to pay for movie tickets, buy takeout food, order goods for delivery and hail a taxi.

    But, there is also concern about the safety of the digital wallets. "Don't think the largest payment technology has solved all of its security problems." commented Fox News.

    Laughter is natural for people. We start to laugh at about four months of age. We start to laugh even1 we start to speak.

    Laughter connects us with others. We laugh more when we are with other people. It's difficult to pretend to laugh. Laughter is2. When people pretend to laugh, most people know it's not real.

   When do people laugh?

    Only 10 to 20 percent of laughter is about something3. Most laughter is about being friendly with other people. Most laughter says, "I don't want to4 with you. I want to be friendly with you." This kind of laughter brings people together.

    We often laugh when we feel nervous. In movies, there is often a joke at an exciting moment when everyone feels nervous. It is usually a(n)5 joke, but we laugh a lot. Our laughter helps us6.

   Why doesn't everyone laugh at the same joke?

    Not everyone has the same sense of7. Some people think a joke is funny, but other people don't think so. People have different ideas about what is funny.

    Our idea of what is funny changes with8. For young children, the world is new. They are interested in many things, so they laugh9. Teenagers often laugh to protect themselves. Adults laugh at themselves and other people with similar problems. They laugh at things that give them stress. Our10 for laughter change gradually.

    If you had billions of dollars, would you donate almost all of it to charity? Well, that's what Mark Zuckerburg, CEO and founder of Facebook, just said he would do.
    Zuckerburg and his wife Priscilla Chan promised to give 90% of their Facebook shares to society. Right now that is about $45 billion, and they plan to donate the money to things like science and education.
    Many billionaires have done similar things. Bill Gates, creator of Microsoft, made The Giving Pledge, an activity in which billionaires promise donate more than half of their wealth to charities. This started in 2010, and now 139 people from 15 countries joined it.
    But giving back and helping others isn't just for big billionaires. People like Zuckerberg, and Gates may have more to give, but people with less are doing it, too.
    Especially around the holidays, people want to do their part and give back to people who are less lucky than them. Schools may have food collections where people bring a few food items, and together they can make a big donation to places like homeless people's homes.
    People also host special events like concerts of runs to be creative while raising money. Regular people donate whatever they can to US charities like the United Way and the American Red Cross.
    Then these charities are able to help US communities in different ways like education, health and improving the lives of the poor. These individual donations come together to make a big difference.

Imagine （想象） walking into a movie theater without being greeted by the smell of popcorn. It's hard to believe, isn't it? For many people, popcorn goes hand in hand with movies. They can't have one without the other. But 1  did this happen?

The 2  between the two is younger than you may think. In the mid-1800s, popcorn was already a popular snack in America. Vendors sold it on the 3  . People, especially kids, loved this street food. In the early 1900s, vendors started to sell popcorn 4  movie theaters.

However, theater owners didn't like popcorn. They believed it would make the experience of watching a movie 5  enjoyable. Eating it would make too much noise during the silent movies.

Later, when movies added sound, the 6  noise problem went away. More and more people went to the movies. Some of them even secretly（秘密地） took popcorn into the theaters. Later, more movie theaters 7  . Some of them agreed people to eat popcorn while they were watching movies.

In the 1930s, the theater owners found that people didn't need to buy popcorn from street vendors. Because popcorn was 8  to make, they could make and sell it themselves. They did that and the smell of popcorn drew more people to their theaters. The 9  made a lot of money, and people enjoyed themselves at the movies.

Today, popcorn is still an important part of the movie-going experience. Roles, a man who once ate three bags of popcorn, said, "People come to theaters sometimes just for the 10 . They don't even care what is playing!"
