NOTE ON USAGE 用法
*Yours faithfully, Yours sincerely, (esp US) Yours truly are the commonest ways of ending formal and semi-formal letters. *Yours faithfully、Yours sincerely、（尤用于美式英语的）Yours truly 是信末最常见的敬语, 用于正规的及半正规的书信均可. The correct style is to use Yours faithfullyto end a letter which begins Dear Sir/Madam (ie when the name of the person being addressed is not known to the writer) and Yours sincerely/truly after Dear Mr/Mrs/Miss/Ms Smith (ie when the name is known but the person is not well known to the writer). 正确的格式是在信的开头用 Dear Sir/Madam（即不认识收信人）, 则信末用 Yours faithfully, 而在信的开头用 Dear Mr/Mrs/Miss/Ms Smith（即知其名而不熟悉者）则信末用 Yours sincerely/truly. *In US English Sincerely, Sincerely yours and Yours truly are often used. 在美式英语中常用 Sincerely、Sincerely yours、Yours truly. *If the writer knows the addressee personally, the first name is used and With best wishes may be added. 若写信人与收信人相识, 则信的开头用收信人的名字（不用姓）, 信末可加 With best wishes. *More familiar still is the use of the first name and Yours (ever). 关系更密切者, 信的开头用收信人的名字（不用姓）, 信末用 Yours (ever).
