求一篇英语作文。100词左右。

Dear Mike,
Recently a crash course for oral English has been set up in our city’s training centre, which guarantees every learner will be able tospeak perfectly fluent American English in merely one month. Appealing as it sounds, the news has successfully motivated me to join in, but what put me into a dilemma is that I am not very certain about the training result. That’s why I’m writing to consult you.
Firstly, what I’m in need of is the English at the highest standard, that is, the teaching quality must be ensured. Furthermore, my schedule won’t be very flexible owing to busy schoolwork, requesting a relative balance between the two sides. Honestly speaking, I’ve been particularly puzzled these days. How much of advertising can be worth believing on earth?
I’m really grateful for any kind of your precious advice.
Yours,
Li Hua
