问题描述：
only one of the students who are present is to speak at the meeting
我想问下.用is是因为only还是因为句子作主语,
答
用is是因为句子的主语是one student是单数，表示众多同学中的一个同学
中间定语从句的主语是students 所以用are
答
only one of the students who are present 是主语部分,其中,who are present 后置定语从句修饰 students ；而真正的主语是only one （student ）,因此谓语动词用is
意思：会议上,只有一名出席的同学会发言.
