Jack is 15 years old. He practices playing the guitar every day, and he is really good at playing the guitar. Emma is Jack's sister. She loves to listen to Jack when he plays the guitar. Jack likes to play country music and classical（古典的）music with the guitar. Emma likes the country music best. She really likes watching Jack play the country music that he creates. Emma also wants to learn to play the guitar so that she can play as well as Jack does.
"Mum, can I take guitar lessons?" Emma asks.
Her mum replies, "It takes a lot of hard work to play the guitar for Jack. Are you sure you have enough time to put it into practice?"
Thinking about all of her favorite activities, Emma isn't sure. She loves her ballet classes, her art classes and her chess classes. Emma realizes that if she plays the guitar, she will probably have to give up another activity to make time for practicing. She doesn't know which activity she would give up because they all mean so much to her.
Finally, Emma decides to enjoy Jack's performance.
