How is your survey on mobile payment going？
How is your survey on mobile payment going? I’m glad I can help with it.
It is generally believed that China is the largest mobile payment market. Nowhere else is the cashless trend more obvious than in China. Most of us are used to paying by scanning QR codes whatever we buy—books, clothes, and electronic devices, to name a few, which is a glimpse into the life of most Chinese like me and my family.
With the widespread use of mobile payment, Wechat or Alipay is the most convenient and safest way to pay. We rarely need to carry a wallet or cash at all. Besides, never will we worry about getting fake notes or having to count change. In short, mobile payment has greatly changed people's life in China.
Personally, I think mobile payment should be encouraged. First, it has won over consumers with its convenience. Another advantage is that there are often discounts if you make mobile payment, as major online payment platforms are competing to have more consumers use their service.
I hope my explanation can be of some help to you. Wish you good luck.

I am glad to hear from you.
I am glad to hear from you. As your close friend, I’d like to talk about the harm of Internet addiction to you as I feel worried to know that you have wasted lots of valuable time playing the Internet games.
As we know, the Internet is a convenient tool to improve our knowledge and skills. However, our life will be greatly affected if we are addicted to it. For example your grades may go down and your health will be going from bad to worse. To make things worse, it can also damage the relationship with your family. So I think it is high time that you got rid of the bad habit. It is a good idea for you to read some meaningful books and do some physical exercise.
I am looking forward to hearing your good news soon．
现在越来越多的人成为低头族（People who can’t help checking their phones all day are known as phubbers. Phubbing trends to involve not only the young people, but also the elderly.)，如何引导低头族抬头？你们班举行了以“拒为低头族”为主题的班会。假设你是学生李华，请为班会写一篇100词左右的发言稿。
Nowadays, we can see many people are watching their mobile phones in subway, restaurants, elevators, roads and so on. There is no denying that people who like the mobile phone are concerned about its attractive functions. Phubbers can’t stop sending messages, surfing the Internet, listening to music and even taking photos by using the mobile phone. Moreover, some people have less time to relax themselves. They make use of the time when they are on the way to school or other places to play mobile games.
However, phubbing disturbs not only our study but also our life. On the one hand, phubbers waste lots of time playing cell phone games and sending messages, particularly in class. Other people also complain they are disturbed when phones ring in classrooms. On the other hand, it can lead to health problems. For instance, using a mobile phone on the sofa can cause back and neck pain.
As far as I am concerned, it is high time that we threw away the phone and raised our heads up. Do cherish everything around us and appreciate the scenery ahead of us. What’s more, we should do more exercises and take part in real-life activities. In a word, only when we use the phone reasonably, can we realize the happiness of life.
