Xiangiang Middle School encourages the students to have different talents.Mike plays the guitar at school,and Max plays the drums.They both play very well.All the students like to enjoy their music.There are more than 50 clubs in the school,but they want to do something different.One day Mike and Max decided for the school's first marching band(行进乐队).But they needed more musical instruments (器) and members.
Mike and Max put up a sign asking anyone who plays a musical instrument to join.Many students were really interested in this.Soon they got a lot of answers.
Sam really wanted to join the band,but he had one huge problem.He could not play any musical instrument.Sophia also wanted to join the band,but she played the harp (竖琴).The harp is too big.She can't carry it while playing.
"How can you be in our band?" Mike asked Sophia."You play the harp sitting down,how can you march?"
All the band members wanted Sophia to play in the band.But they also wanted to march.Where is the way?
Then Max had an idea.He invited Sam and Sophia to join the band.Max asked his father for help.His father is good at creating.He made a big board with four wheels.Then Max asked Sam to ride a bicycle to pull the board with Sophia and her harp on it.Sam could use the bicycle's bell as a kind of musical instrument.
