Dear Professor Smith, 

Our school is planning to have a lecture on how to learn English effectively for middle school students next week and I'm writing to ask you to come and give a talk on English learning strategies. It will help us understand how to learn English in effective ways and also increase our interest in learning it, thus making us learn it actively. Do you think one and a half hours will be enough for such a lecture? Please let me know as soon as possible so that I can make arrangements. 

Looking forward to seeing you and enjoying the lecture.   

Best wishes.  

                                                                                    Yours,

                                               Li Hua
