Dear Jim,

　　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.

　　Yours,

　　Li Hua

　　Nowadays，public square dancing is becoming more and more popular. Most of the public squares are crowded with dancers，especially in the morning and evening.

　　We all agree that public square dancing is a good way to keep healthy，especially for the old. Besides，it is money-saving. But it also causes noise pollution. Many people suffer from the noise caused by the loud music. They can't work，study or sleep well. They feel very angry and some even argue with the dancers.

　　In my opinion，the dancers should turn down the volume while dancing. In addition，our government should build more public places for them，such as squares and parks. Then people can have fun dancing without disturbing other people.
