In order to collect funds for charitable donation，my sister’s school was going to organise a concert.One of the performances was a short drama called “Christmas Eve”．When the notice was announced，my sister went to register for the drama immediately because she was really passionate(热情的) about role playing.
On the day when students were given their respective roles，my little sister came home without any expression，and her lips tightly closed.
“Are you chosen？” We asked her carefully，trying to not hurt her feelings.
“Yes，” She said a word only.“Then why are you unhappy？” I asked.
“It’s because of my role！” She shouted angrily.
We all knew that “Christmas Eve” only had four characters: the father，the mother，the son and the daughter.“What is your role？”
“They asked me to play the role of the dog ！” After saying that，my sister rushed upstairs，leaving us watching each other in silence.We did not know whether to congratulate her or to comfort her for her role as a dog.Dad talked to my sister after dinner，but we did not know what they had talked about.
Anyway，my sister did not quit the performance .She was active in each practice and rehearsal(排练)．We were puzzled about what was there to practice in order to play the role of a dog.But my sister was really into the practice，and even bought protection cap for her knees，so that she would not feel the pain when she crawled(爬) on the stage.She also told us that the dog’s name was Danger.
I noticed that every time when my sister was back from the rehearsal，her eyes shone excitedly.I did not know about the real meaning of her excitement until the day of the performance.
On the grand day itself，I opened the pamphlet and found my sister’s name “Jane—Danger (Dog)”．I looked around，the hall was fully seated with many of my friends.I sat back quickly—it’s not such an honour to have a sister who acted as a dog.
Luckily，the light faded out and the performance began.
I heard somelight laughs from the audience around me.
【答案】Luckily，the light faded out and the performance began.“The father” came out first，followed by other family members.They sat together to discuss the meaning of Christmas.While the family members were talking，my sister Jane，wearing a yellow furry dog costume，came to the stage.She crawled slowly with her hands and legs together，and then yawned，before she settled in front of the fireplace.Then the dog Danger began to sleep.The series of movement were really like that of a dog.
I heard some light laughs from the audience around me.They probably noticed my sister’s movement.Her performance was so excellent that she must have paid great effort during practice.My sister did not said one single word that night，but she won the applause and attention of everyone.After the performance ，my sister told us that what changed her attitude was Dad’s words：If you act as a dog with the attitude of the main role，the dog will become the centre of the spotlight.
