"Yeah,I'm attending the tryouts this weekend," Kevin announced. "With my voice,I'm pretty much guaranteed a spot.I don't even need any practice as I am so talented.Imagine they'll want me to perform lots of solos(獨唱),too." Everyone knew that Kevin had a fantastic singing voice.Normally,Alexander just ignored him,but he couldn't help imagining himself as a member of the choir.Wouldn't it be fun,he thought,to sing with other kids every day and have someone actually teach him about singing? On the tryout day,Alexander took a deep breath,walked into the building,registered at a large table,and then waited nervously in the hallway.The only one who didn't look nervous was Kevin.And why should he be?He has performed as a soloist many times.Alexander,on the other hand,had never taken a musical lesson in his life,much less had performed for an audience. After a while,the choir director,Mr.Robeson,walked in and told the kids that they were to sing a song individually,sing as a group and answer some questions.Soon the individual test began.When Alexander stood on the stage,he tried to calm down and pretended he was singing in the shower.He felt satisfied when he was done,at least until Kevin's turn came.As Kevin3 s confident voice filled the room Alexander realized that he would never sound that good. Next,Mr.Robeson put the kids into groups of four or five and asked them to sing together.Kevin's group sang right before Alexander's,and even with four other boys singing,Kevin's voice clear and distinct;it seemed to reach the farthest corners of the room. 注意: 1.寫作詞數(shù)應(yīng)為150左右; 2.請按如下格式作答。 Then came the time for Alexander to sing with his group.___________ Finally,Mr.Robeson told Alexander that he made it,not Kevin.___________
