1.We have all experienced days when everything goes wrong.
我们大家都有过事事不顺心的日子。
语言点:句子结构分析:when引导的是定语从句，请特别注意不是时间状语从句，被修饰的先行词是days。All的作用是突出强调we。
2.A day may begin well enough, but suddenly everything seems to get out of control.
一天开始时，可能还不错，但突然间似乎一切都失去了控制。
语言点1:句子结构分析:but并列连接两个转折关系的句子。
语言点2:well enough的意思是“足够好”，注意不可说enough well!
3.What invariably happens is that a great number of things choose to go wrong atprecisely the same moment.
情况经常是这样的，许许多多的事情都偏偏赶在同一时刻出问题。
语言点1:句子结构分析:what invariably happens是主语从句。
语言点2:choose to do sth.的意思是“碰巧做某事”，相当于coincide/conspire to do sth。choose togo wrong在此是拟人修辞格。
