Not only you but also one of your students -------to attend

应该是填 is going吧
Not only you but also one of your students is going to attend the meeting that is due tomorrow.
不仅仅是你,还有你的一个学生,将会出席明天的会议.
not only … but also 连接两个主语时,谓语动词要和与其最近的主语保持人称和数的一致.
最近的主语是 one of your students,表示单数.所以谓语要用单数
再问： one of的用法。
再答： one of .... "什么的之一" 比如说 Look, there are many boys dancing. One of them is my best friend. 看， 那有很多男生在跳舞，他们中的一个是我一个最好的朋友。 谓语要用单数。
