Standing in front of the blackboard，Christina Xu announced（宣布） the start of the class.Eighteen students stood up，shouted their greetings of "good morning" in Chinese，and started the 90-minute class.This is a usual Chinese class at Walter Payton High School in Chicago（芝加哥）. （1）这18个学生被分成几个小组练习中文说和写的技能。
        Xu tried her best to make it easier for students to learn Chinese well. （2）In sentence-making part，the students were encouraged to write down as many Chinese sentences as they can.Mistakes were seen very often.But Xu would correct the mistakes together with humorous comments，then the students laughed and easily remembered the correct ones.
        （3）This school is one of the 41 public schools in Chicago that offer Chinese classes. "In Chicago，public schools offer 12 foreign languages for students to choose.In 2018，Chinese became the second most chosen foreign language.I think it was because of the rapid development and rising of China on the world's stage." said Jane Lu，CPS （Chicago Public Schools） Chinese World language coordinator and director of the Confucius Institute（孔子学院） in Chicago.
        Steven，a sixteen-year-old junior at Walter Payton started to learn Chinese in primary school and has kept learning ever since. "（4）我选择中文是因为我认为它将会是最有价值的语言。" Steven said， "More and more people speak Chinese around the world and the United States has a lot of relations with China，so I believe learning Chinese will help me in my career in the future."
        CPS started to offer Chinese as a second language choice in 1999 Only several schools had Chinese classes until 2006，when the Confucius Institute in Chicago was built.The institute is responsible for planning Chinese courses and training Chinese teachers in CPS.It also sends more than 20 CPS students to China for exchange and study every year.
