找出下面这封辞职信在写作技巧上的不足之处，并将其加以改进。　

　　此信的不足之处如下：

　　1.第二段陈述辞职理由时用词过于直白，语气不够委婉，对目前的工作和公司有些许贬低(take a“much bigger job”;“a substantially greateasalary”;the opportunity…“cannot be matched in this company”)。

　　2.信的结尾虽表达了在离职前继续做好工作并帮助接替的人，但语气不够热情，似乎只是公事公办。

　　3，作者没有对上司和同事表示任何感谢。

　　改进后的辞职信：

Dear Mr Wang：

　　As we discussed in your office yesterday，I have decided to submit my resignation as budget director，effective two weeks from now Oetober 10

　　I have enjoyed my working at the Houston Food very much.The fellow staff are so kind and cooperative.You created a perfect environment for me for learning and growing.And，of course，I would not feel competent to accept the new job if I had not had the rieh experience here I will always be grateful for your confidence in me.

　　Reluctant though I am to leave the Houston.I am sure you understand my position.I felt that I simply could not turn down a position that appears to offer such promise The additional income is a faetor，of course，but a relatively minor one.What I am most excited about is the chance to assume broad accounting responsibilities that could lead to exciting new opportunities in financial management

　　I am，of course，determined tO perform my duties in the best possible manner in the tWO weeks I have left If you can think of anything I can do to help my replacement take over the work of budget dimetor，I’II be glad to have your suggestions.

　　Sincerely，
