参考词汇：垃圾分类 trash sorting
Having learned that you are interested in the trash-sorting program promoted recently in China, I am here writing to give you a brief introduction.
As far as I know, Shanghai has become the pioneer of our country's waste sorting policy. As of July 1st this year, the residents in Shanghai have not been able to dump their waste bags in whichever bin was closest. On the contrary, domestic waste is required to be classified into four categories: dry refuse, wet trash, recyclable waste and hazardous(dangerous) waste.
Faced with the new rule, many citizens in Shanghai are finding it a little too complicated, with every item of waste now under careful scrutiny(examination) and classification. Still, there are more people who warmly support the policy because it helps people to cultivate greener lifestyle habits and helps China to become a more beautiful country.

I’m glad that you are caring about the development of my hometown. Now I will tell you something about it.
Great changes have taken place since the19th National Congress of the Communist Party of China. The targeted poverty reduction has reached its ideal aims. Many poor families have got effective help from local government and have improved their life greatly. Many old houses are replaced by new tall buildings which are surrounded with green trees and colourful flowers. The rivers that had been polluted seriously before are getting clearer and clearer. Besides, all kinds of fishes return the rivers. The sky is filled with white and cleaner clouds.
Please come to visit my hometown in the near future.
The Advantages of Online Payment
Online payment has been advocated around the world, which is the future way to pay bills. In China, Alipay is popular everywhere, even the small business can be finished by this advanced way. People play the joke that they don’t need to worry about the lack of cash. The advantages of online payment are obvious.
Firstly, it saves people’s time to pay bills. The use of online payment is carried out with a smart phone. Especially when we go to the supermarket, there are always a lot of people waiting in the long line. The process of costing customers’ time is to take out the cash or use the credit card, because both customers and cashiers need to count the money or check the bills. But now the cashier can just scan the phone and the bill will be paid and the customer can check quickly.
Second, people don’t have to worry about getting the fake cash. Many years ago, people were easy to get fake money as they received the change. But now, as the cash have been used less, people won’t receive the fake cash without paper money. With the development of new applications, our life will be much convenient.

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．
I'm glad to hear from you. And now I’m very happy to share something about Chinese tea culture in reply to your last e-mail.
Chinese tea culture started about 4,000 years ago and drinking tea gradually became an amazing tradition. In China, people drink tea almost everywhere and in most of their spare time. Some Chinese believe that tea benefits people’s health a lot. Drinking a cup of tea makes people relaxed and refreshed. Others treat guests or friends to tea drinking in social communication.
Probably, you’ve got a general picture of tea culture after my introduction. Then, how about coming to China to experience it yourself? Maybe, you will fall in love with it.

假定你是李华, 你的美国笔友Mark本学期开始选修汉语课程。最近，他给你发来电子邮件，询问如何学好汉语。 请给他回一封邮件，针对如何学好汉语提一些建议。
I know from your e-mail that you are learning Chinese this semester and ask me for some advice. Here are my suggestions.
First, you should listen carefully to your teacher in class and practice as often as possible after class because mastering a language requires a lot of practice. Second, I’d like to recommend you to read some Chinese story books, which helps you enlarge your vocabulary and understand the different meanings of the words. Third, I think it is a good idea to communicate with Chinese native speakers. Last but not least, watching Chinese movies and listening to Chinese songs are good ways to learn idiomatic Chinese.
I hope my advice will be helpful.
How is it going? Our school is going to hold a Chinese Summer Camp for international students this summer vacation. Knowing that you are keen on Chinese culture, I am writing to invite you to join in it.
