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.

    Are you good with money? Do you get pocket money from your parents or do you work to make money? Read on to find out about British teenagers and their money!

    Pocket money

    Most teenagers in Britain receive pocket money from their parents. They might have to do some housework to get pocket money, including cleaning, cooking, washing dishes and so on.

    Part-time work

    A part-time job is a choice for teenagers who don't have pocket money or who want to get extra money. About 15% teenagers have a job. Only children over the age of 13 can work. Popular part-time jobs for teens include babysitting, delivering (递送) newspapers, restaurant work and shop work. Children in Britain can work two hours a day at the most on a school day but not during school hours. During weekends and school holidays, they can work longer hours.

    Bank accounts (账户)

    Some children and teenagers have a bank account. There is no age limit at which you can open a bank account, but a bank manager can decide whether to open an account for a child or a young person. Parents can put pocket money directly into their child's bank account. Most banks have a prepaid bank card designed for young people.

    Mobile apps

    Many companies have made mobile apps for children, including GoHenry, Osper and Gimi. Parents can add money to their children's accounts and check to see how the money is spent. Children can choose to save their money or spend it using a card. The apps suggest that kids from 8 to 13 can use the cards.

    So, many teenagers are getting experience working part-time, dealing with banks and deciding whether to save or spend their money. These are all steps towards becoming a financially independent (经济独立的) person and making and looking after your own money.

    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.

Mobile phones are becoming more and more popular not only with adults but also with students. However, they also have become a problem for middle schools in the last few years.

Some children have got mobile phones as Christmas or birthday gifts, and more will ask their parents to buy phones for them.

Many students like mobile phones because they are easy and quick. Some parents feel it convenient because they can get in touch with their children. Some teachers think using mobile phones is a distraction(分心的事)to students during school hours and mobile phones also give them much trouble in their classrooms. Sometimes students send phone messages to cheat(作弊)during exams. A new study says that some teenagers even hurt their fingers because of the over-use of mobile phones. They keep using mobile phones for more than ten hours during a day.

Many teachers suggest that students should not have phones at school, but if there is a good reason, they can leave their phones at the school office. Many people think they understand why parents would want their children to have them, but they agree school should let the students know when they can use their mobile phones.
