Dry January is a custom of abstaining from alcohol for the month of January, particularly practised in the United Kingdom. 

“一月戒酒”指的是在一月戒掉酒精的一种习惯，这种习俗一般指在英国。

In Britain, it's bottoms up from the week before Christmas till the last firework explodes in the sky announcing the new year. The last Friday before Christmas - popularly known as 'Mad Friday' - is one of the busiest periods for the country's pubs and clubs. 

在英国，从圣诞节前一周，一直到烟火点燃夜空宣告新年来临，这段时间人们都很爱喝酒。圣诞节前的最后一个周五（也就是“疯狂的周五”）是英国酒吧和俱乐部最忙的一天。
