notonly...butalso...谓语动词有就近原则。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。
例句：
1.Not only the students but also the teacher was against the plan.
不仅是学生，连老师也反对这项计划。（谓语动词最近的主语是teacher，要保持人称和数的一致，所以用was）
2.Not only the teacher but also the students were against the plan.
不仅是老师，连学生也反对这项计划。（离谓语动词最近的主语是students，要保持人称和数的一致，所以用were）
扩展资料：
1.not only … but also 连接两个分句,并且 not only 位于句首时,第一个分句中的主语和谓语要部分倒装。
2.not only … but also不能用在否定句中
3.not only … but also 连接两个并列成分时,可以省略 but 或 also ,也可以把 but also 都省略掉。
4.not only A but also B = B as well as A,但前者的强调重点在 B ；后者的强调重点也在B。
