首先以one of结构作主语开头，一般情况下，谓语动词都是用单数。

比如: one of the students comes from America.注意: 如果one of +可数名词复数 这个结构用作定语从句的先行词，从句谓语动词用复数。但如果前有表示唯一的词修饰时如the only、the very等修饰时，谓语动词用单数。比如:She is one of the students who were praised at the meeting.她是在会上被表扬的学生之一。He is the only one of the students who was praised at the meeting.他是在会上唯一被表扬的学生
