The teacher said that they "were" hard working students.那空为什么填were?

问题描述:

The teacher said that they "were" hard working students.那空为什么填were?

students 是复数 主句是过去时 从句要用过去时 were

从句主语为they,谓语动词用复数
又因为主句谓语为said,从句随主句时态变化,用一般过去时

因为主语的谓语动词said是过去时,所以从句的谓语动词也就相应过去化(were)了.

可能的解释是:他们曾经是,现在不是了

said 因此 老师说这句话发生在过去 因此从句里的BE动词也应该用过去式
因为是they 所以是are 过去式是were
