Note that in UK English if you start with Dear Sir or Dear Madam, you should end with Yours faithfully. But if you use the person’s name, you should end with Yours sincerely. This rule may seem arbitrary, but it is one of the rules of formal letter writing that is widely known in the UK; therefore I recommend you stick to it. However, there is no such strict rule in the US.
要注意在英式英語(yǔ)中，如果你的郵件以“尊敬的先生”或”尊敬的女士”開(kāi)頭，那應(yīng)該以”你忠誠(chéng)的……“結(jié)束。但如果你知道對(duì)方的名字，應(yīng)該以”你真誠(chéng)的……“的結(jié)束。這個(gè)規(guī)定似乎太武斷了，但就是英國(guó)眾所周知的正式郵件寫(xiě)法之一，所以我推薦你最好按照這個(gè)原則寫(xiě)。然而，美國(guó)沒(méi)有這門(mén)嚴(yán)格的規(guī)定。

Here are some example closing sentences for emails:
