Dear Eric，

I’m glad to hear that you are interested in Chinese cross talk and I’m writing to introduce Ma Sanli， one of the most famous Chinese performing artists of cross talk.

Ma Sanli was born on September 25， 1914 and died on February 11， 2003. At an early age， he had cross talk because of his poor family. It was in 1930 that he started to perform on stage. During his whole life， he created a large number of excellent works， many of which are still popular among people now. His unique style has a positive effect on the development of Chinese cross talk and he is considered as a master of humor. You can appreciate his works on Chinese artist website.

Wish you great progress in your learning Chinese cross talk.

Yours，

Dear Adam，

How are things going？ I’m glad to tell you something about fishing.

On a sunny morning in summer， my father and I drove to the seaside to fish. We took some clam worms， some bread and water. On arriving at the seaside， I felt excited. We took our fishing poles out， put clam worms on the fish hooks and threw them into the sea. Then we waited patiently. After a while， my father got a fish. However， I am not good at fishing and got nothing. So my father continually gave me some advice， which helped me greatly. Then I caught a lot of fish. At five o’clock， we returned home， feeling very happy.

Last Saturday， a basketball game between Class 1 and Class 2 began on the basketball court.

The two teams spent much time preparing for the game before the sports event. And each team fought for winning the game. At first， Class 2 fell behind Class 1 in the game， but they didn’t give up and seized every opportunity to attack. In the end， Class 2 defeated the opponent by one shot into the basket， which was beyond everyone’s expectations.

As far as I am concerned， the team spirit is the key to their remarkable performance and self-belief also contributes to their success.
