I am a student who attended the training course entitled 'The Challenges and Opportunities after China' s Entry into WTO'  in the auditorium of your research institute last Thursday and Friday. I am writing to you to express my dissatisfaction with your organisation and the poor facilities of the training course.   We were present at the auditorium at 8 o' clock on Thursday morning according to the schedule. But the lecturer did not arrive until 8: 40am, which was a nuisance for the whole audience to wait. This is not the end of the story. When the lecturer started the speech, something was wrong with the microphone. You see, there are nearly 300 audiences in the hall. The people at the back of the auditorium could not hear a single word.What is worse is that the staff here did not take any remedial measures to fix the sound system in time.   I sincerely hope that this kind of situation will not reoccur, for it not only wastes us a lot of time, but also influences your reputation.   Thank you for your attention to this letter.   　　Yours faithfully,. 　　Mary Bush .   　　这篇作文无论从字数、结构和流利性，还是从连接词、复合句的使用以及背景知识的运用来看，都达到了要求，入情入理，堪称佳作。
