I won\'t, either. 假如你不去那里,我也不去 n 二、neither...nor... neither...nor...表达"既不……也不……"。其含义与否认旳,可连接任意两个并列旳成分。 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,也应遵照"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,同步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,表达"两者中没有一种"。 n 例如:  Neither of them likes football. 他们俩都不喜欢足球。   15.finally  adv. 终于,最终 final  adj. 最终旳 He finally got to the top of the moutain. 近:in the end; at last
