D. Answer the questions(根据短文内容回答下列问题。)Every girl dreams and Lisa is no exception. She has read dozens of books on how to be a ballerina(芭蕾舞女演员). "Swan Lake" is her favorite. She hopes one day her dream will come true. She has taken ballet lessons and all her teachers are sure she is a good student.
One day she saw a poster that a famous ballerina group will be performing in her hometown. Confidence filled her heart and she was so excited. Her thoughts soon ran wild. "I must meet up with the leader of the group and show him my skills," she whispered to herself. When the troupe(舞团) arrived, Lisa put on her ballet outfit(芭蕾舞装) and hid in the dressing room. To her luck, the leader entered and she timidly(胆怯地) knocked at the door. She bravely approached him and handed him a bunch of red roses. The thorns(刺) hurt her hand but she did not care about the pain. The leader watched her action as she told him her dream. "Alright, you dance and then I will give you my conclusion." But half way through the dance he stopped her and said, "I'm sorry you're not good enough!" On hearing this Lisa ran as fast as her legs could carry her and was upset. She decided to give up her dream.
Many years later, she heard that the same ballet troupe was performing in her town again. Bitter memories of the leader's unfriendly words came flooding back to her. This time she decided to find out why the leader had told her she was not good enough. This was his reply, "I tell this to every student." Then she got a further shock from the leader, "I remember your gift of roses and how the thorns had hurt your fingers but you carried on bravery. If you had treated ballet like that and did not give up so easily, therefore, you still deserve my conclusion!"
