Professor Peter和他的四个学生,后面用are没错啊,为什么用is呢? Professor Peter, with four of his students, are attending a symposium in Nanjing on energy. A B C D B, are----is
改成这样你就明白了: Professor Peter is attending a symposium in Nanjing on energy, with four of his students. 这是主谓一致经常考的题目. 主语是Professor Peter with four of his students可以看成定语 谓语就是单数了. 类似: The boss with four boys is coming tonight.
