Dear Mr. / Ms，
We are much concerned that your sales in recent months have fallen considerably. At first we thought this might be due to a slack market， but on looking into the matter more closely， we find that the general trend of trade during this period has been upwards.
It is possible that you are facing difficulties of which we are not aware. If so， we would like to know what we can do to help. We， therefore， look forward to receiving from you a detailed report on the situation and suggestions as to how we may help in restoring our sales to their former level.
Yours faithfully
尊敬的先生/小姐，
我們非常關(guān)心你方銷售近幾個月大幅度下降。開始我們以為是市場疲軟，但仔細(xì)研究問題，我們發(fā)現(xiàn)過去這段時間貿(mào)易的總趨勢是上升的。有可能你方面臨我方還不知道的困難，如是這樣，我方想知道是否能幫助什么。我們期望收到關(guān)于問題的詳細(xì)報告，及建議我們怎樣幫助才能把銷售恢復(fù)到原來的水平。
