I won't, either. 如果你不去那里，我也不去n 二、neither.nor. neither.nor.表示"既不也不"。其含义是否定的，可连接任意两个并列的成份。 例如：She likes neither butter nor cheese. 她既不喜欢黄油也不喜欢乳酪。此句中neither.nor.连接两个宾语n 当neither.nor.连接两个主语时，也应遵循"就近原则"。例如：Neither dad nor mum is at home today. 今天父母都不在家n 若将neither.nor.句型变为肯定句，只需把neither.nor.改为both.and.即可，同时谓语动词必须用复数形式。n 例如： Both dad and mum are at home today. 今天父母都在家。 n 还可以单独使用neither作主语，表示"两者中没有一个"。n 例如： Neither of them likes football. 他们俩都不喜欢足球。 15.finally adv. 终于，最后final adj. 最后的He finally got to the top of the moutain.近：in the end; at last专心-专注-专业
