This book is of particular importance to my IELTS test,but I fail to obtain it from my school library as well as local d you please tell me whether the National Library has the mentioned book?If so,could you please do me a favor of photocopying and sending it to me by EMS as soon as possible?l would like to pay for the relevant expense.
Thank you for your kind assistance.

尊敬的先生或女士：
我是天津中學的一名高三學生，不知道是否可以佔用您的一點時間幫我找本叫《雅思聽力理解》的參考書?它的封面是綠色的，由外語出版社於20xx年出版的。
這本書對於我的.雅思考試有着特別的重要意義，但是我在我們學校的圖書館和當地書店都沒有找到它。 不知道國家圖書館是否有這本書?如果有的話，不知您是否可以儘快幫我複印一下並用特快專遞寄給我呢?相關費用我會進行支付的。
希望能得到您的善意幫助。
真誠的，
李毅
