　　A Letter of Invitation to Give a Lecture

　　Dear Prof. Smith, it is my honor on behalf of the Student Union to invite you to give us a lecture on English learning.

　　As is known, you are a prestigious scholar in the second language acquisition and English literature.

　　Your instruction will be invaluable to our English learning.

　　As non-English majors, we have difficulty in reading comprehension, for we always are frustrated by the unfamiliar vocabulary.

　　And it is never easy to memorize so many words while we have to pay more attention to our own majors.

　　Besides problems in reading, we can not express our ideas in fluent English.

　　Although we can pass English examinations,we can not communicate effectively with foreigners. It will be greatly appreciated that you could give us some suggestions concerning problems mentioned above.

　　We are all expecting your lecture.

　　Thanks again. Yours sincerely, Jack
