First built in 2005, the Wuhan-Guangzhou high-speed railway went into operation on December,26th,2009. Overall length of its main line is 1068 kilometers, and it goes through the following three provinces: Hubei, Hunan and Guangdong.
The speed of the Wuhan-Guangzhou high-speed railway is 350km/h,the fastest speed in the world now, which makes it only three hours needed from Wuhan to Guangzhou, seven hours less than before. Besides, there are all kinds of facilities in the train, which make your trip safe and comfortable, so it is more humanitarian.
However, the only fly in the ointment is that the train fare is too high and the station is quite far away from the downtown area.
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’m writing to tell you more about the new form of sharing bike--mobike mentioned in your latest letter.
It’s very convenient to use if you have a smartphone. What you do is to find a nearest mobike through the APP, scan the QR code on the bike, and enjoy your trip.
Compared to other forms of sharing bike, the greatest advantage of mobike is that you can easily find one and never worry about where to park it. It is becoming a new trend as a means of transportation, which relieves the traffic pressure and does good to the environment as well.
Hope to ride a mobike with you in China.
With the development of the Internet and the popularization of computers, shopping on the Internet has become a commonplace in our life. Here consumers can buy almost everything they need.
Shopping on the Internet has a lot of advantages, of which themost important is perhaps its convenience. People don't haveto waste a lot of their energy and precious time to go from one shop to another to choose the commodities they like. This is especially desirable to the old, the sick and the busy people who cannot go to the shops in person（亲自）. The goods come in all shapes, sizes and colors on the Internet. All they need to do is to sit in front of their computers and click the mouses（点击鼠标）. The commodities they order will be delivered（运送）to them promptly.
However, shopping on the Internet also has its disadvantages. The first disadvantage is that the consumers can't see the goods or try them on（试穿，试验） personally. Sometimes, the real goods may not be the same as what they have seen on the computer. The second disadvantage is that some shops on the Internet are not registered（注册）. They will never deliver anything to you after they get the money from you. Once cheated, you will find that you have nowhere to go to complain.

Recently, students in our class have had a discussion on whether space is worth exploring.
30% of us thinkspace exploration is not worthwhile. They think space is too far away from us and our daily life. And the money spent on space exploration can be used to solve the earth’s problems such as starvation and pollution.
On the other hand, 70% thinkspace is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast. What’s more, with further space research, we may solve the population problem by moving to other planets one day. Also, space research will enable us to find new sources to solve the problem of energy shortages on the earth.

Good afternoon, ladies and gentlemen, I am Li Hua, from Yucai Middle School. It is a great honor for me, on behalf of our school, to deliver a speech about the changes of our village to you.
Our village is a small one with nearly 100 famrilfes and a bout500 people. It used to be very dirty and its people led a poor life . However, great changes have taken place since 1978 when the reform and opening-up policy was carried out. Now it is taking on a new look. Piles of tall buildings stand beside the clean streets and the people here enjoy acomfortable life.
In the past, many people did not have enough money to feed their family, let alone went to school. But now, not only can we study in theclear and clean classrooms. but we receive free compulsory education.Thanks to the Chinese Communist Party, without which, our life won't become better and better. May our hometown more and more beautiful.
“ New Wenchuan， Great Changes＂为题，向 China Daily写一篇通讯稿，对帮助过的社会各界人土表示感谢
As the picture shows that ten years ago on May12, a big earthquake struck Wenchuan, causing many houses destroyed and thousands of people losing their fives in a short time. Many more were homeless. It was such a disaster that almost everything was in ruins.
Now a decade past, with the help of people from all walks giving a helpful hand ,a new Wenchuan appears in front of us. Piles of tall buildings stand where it used to be ruins. The city looks like a beautiful garden. People here recover from the earthquake both physically and mentally, enjoying a comfortable life.
In my opinion, without the support of our Motherland,the survivors in Wenchuan can not lead so comfortable a life as it is now. I am proud that I live in such a mutual-aid country.
