Dear Mr. Johnson,
Thank you very much for your letter of 3 May .
We wish to offer our sincere apologies for the long delay in replying to your letter. We have recently moved our headquarters to a new location in the south of city and this has resulted in some considerable delay in replying to enquiries. The move has now been completed and I can assure you that there will be no more delays in the future.
The catalogue you require are enclosed and I hope that you will continue to use us as your main supplier.
Your sincerely
非常感谢您年5月3日的来信。
我们为延误很长时间回复您的.信件表示真诚的歉意。
我们最近把公司总部搬到位于城市南部的一个新地方。
这导致了大量回复询问信函的延误。
现在搬家已经结束并且我可以向您保证今后不再会有延误。
我随信附上您要的目录。
我希望您继续把我们作为您的主要供应商。
