正确精准的答案应该填 was it
即：He thought it was too late to change her mind,was it?
翻译为：他觉得太迟了而不能改变主意了,是吗?
①当主句谓语是think,believe,expect,suppose,imagine等引导的宾语从句时,疑问部分与宾语从句相对应构成反意疑问句.
②陈述部分含有表示否定意义的too...to...（太...而不能...）（too后接表感情的形容词时例外）结构时,疑问部分要用肯定形式.
如：The old lady was too moved to speak,was she?
那位老太太感动得说不出话来,是吗?
③注意：too...to...（too后接表感情的形容词,如：pleased等）不表示否定意义时,疑问部分则用否定形式.
如：They are only too pleased to help us,aren't they?
他们很高兴帮助我们,是不是?
