今天,有一位来自哈萨克斯坦的小提琴专家来听陈老师给我们上课。我觉得特别兴奋。我已经听过两次他的演奏音乐会了,他和陈老师很熟,我们都叫他萨莎。他的琴拉的特别棒,还会好多中国曲子。可是,今天,他却来跟我们一起上课,这可还是第一次。我们上课的时候,萨莎也跟我们一样认真? Today, there is a violin expert from Kazakhstan to listen to Professor Chen to give us class. I feel particularly excited. I have heard twice his concert, he and Chen are familiar, we call him Sasha. His piano is very good, but also a lot of Chinese music. However, today, he came to class with us, this is the first time. Is Sasha as serious as we are in class?
