再过几天英文

or in a few days

several days latter

Have patience, we'll be home within a few days.

再过几天就是假期了 In a few days is a holiday

要学地道英语，就想要学地道中文一样，光是学个单词，词组是没有用的，要联系上下文。过几天他又来了。 He came again after a few days.过几天他还会来的。 He will come again in a few days.这样的日子你还能过几天？ How many days can you live like this?所以以后提问请把上下文一起写上，免得那着一个‘牛头不对马嘴’的答案，去别处被人取笑。

Christmas Day is several days away.(课本里教的)或形象一点的有Christmas is on the corner.(地道的用法)
