1.Dear Mr/Ms,

　　Yours faithfully

尊敬的先生/小姐，

　　對三月十日來信所要目錄和價(jià)格單，很抱歉不能馬上寄去。印刷商兩周后供貨，一旦收到，我們將給您寄去一份。

　　您誠摯的

2.Dear Mr/Ms,

　　I was very concerned when I received your letter of yesterday complaining that the central heating system in your new house had not been completed by the date promised.

　　On referring to our earlier correspondence,I find that I had mistaken the date for completion. The fault is entirely mine and I deeply regret that it should have occurred.

　　I realize the inconvenience our oversight must be causing you and will do everything possible to avoid any further delay. I have already given instructions for the work to have priority and the engineers working on the job to be placed on overtime. These arrangements should see the installation completed by next weekend.

　　Yours faithfully

尊敬的先生/小姐，

　　昨天收到你的來信，抱怨你新家的中央加熱系統(tǒng)未按規(guī)定時(shí)間裝好，對此我非常關(guān)心。參考較早的通信，我發(fā)現(xiàn)我搞錯(cuò)了完成日期。錯(cuò)誤完全是我的，對此我非常抱歉。

　　認(rèn)識到我們的疏忽給你造成的不便，我們將竭盡全力避免再耽擱。我已指示這項(xiàng)工作優(yōu)先做并讓工程人員加班。這樣安排會(huì)于下周完成安裝。

　　你誠摯的
