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.

     Xinhua News Agency reported 3,000 yellow school buses started their service in Chongqing1the end of 2011. These school buses are like the ones in the US as we usually see on TV and in 2 .

    The school buses are bright yellow in colour. They are 3than the army's cars. They are from the US. The yellow school bus has a big 4.This keeps the students safe when other cars crash into the school bus. The bus also has some   5devices(设备), such as warning lights and a stop signal arm.

    With more and more cars on the road, the traffic jam will happen. How do we see it and how can we solve the problem?

    We know that the traffic jam(堵塞)happens in many places, especially in big cities. What are reasons for the problem? On one hand, some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable. On the other hand, a growing number of people hope to use their cars to show off (炫耀). What's more, years of research has shown that one of other reasons for the traffic jam is the driving habit. For example, many young people enjoy driving very fast, so they can feel excited. At last, most of them hardly care about the speed rules.

    Many governments are working at how to make the traffic better. In my opinion, firstly, the governments should educate those people who have cars or plan to buy cars. The governments must make them know that the traffic jam is very serious, and set up a much more perfect traffic system (体系)to solve the traffic pressure.

    It is difficult for the parents of every family to teach their children to be responsible (有责任的) for housework.

    The Shatian School in Shanghai is making its students do housework for their parents. The third graders(三年级学生) must learn how to cook and clean, sixth graders do the laundry(洗衣服) and seventh and eighth graders cook balanced meals with 15 yuan.

    Many parents think it's a good way for children to try housework but they don't know how to do it at home. With the following ideas, you really can get your children to help at home.

    If you want to make your children think that they can do everything quite right, please don't always scold(批评) if them but give them lots of praise at home. Talk more about what they did right, not about what they didn't do. If your child finishes some difficult work, give him or her a Sunday trip or a ball game with Dad as a reward.

    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.
