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.

    When parents send their children to school，often they don't know what happens day to day. Parents depend on what their children tell them about they are doing and what they are learning. Generally schools will host parent-teacher meeting at least twice a year. Parent-teacher meetings are short meetings between parents and their children's teacher. Usually they are held when teachers give put a student's grades for the term. The parent-teacher meetings give teachers a chance to let parents know how their child is doing. A teacher will let a parent know the student's advantages and bring to the parent's attention any problems with grades or behavior(行为).The meetings also offer parents the chance to ask questions and see what their child is learning.

    Most children do not go along with their parents to the meetings. This allows both the parent and teacher to talk honestly about the child's progress without making the child feel bad. Usually a teacher will offer advice to the parent on how to support their child's education.

    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.

    The world is in danger. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain(剩余). The others have been destroyed(破坏) by man. We are changing the earth, the air, the water and everything that grows and lives. We can't live without these things. If we continue doing like this, we will destroy ourselves.

    What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation(对自然环境的保护) is necessary. Many are helping to save our world. They plant trees and protect animals in forest. In a small town in the United States, a large group of volunteers cleaned the banks of their rivers. Young people may hear about conservation through a record called No One's Going to Change Our World. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to protect wild animals.
