Dear Mr. Smith,
_______________________________________________________________________________ 【答案】Dear Mr. Smith,
How is everything going recently? I am writing to invite you to be our honored guest speaker for the coming lecture on different English dialects.
As a language expert, you must have a lot to say about this topic. We know you have done a lot of research on English dialects. Therefore, we would greatly appreciate it if you could come and share your study and findings with the students. I believe your vivid speech would help them understand English much better. The speech will be from 3 pm to 4 :30 pm next Friday in the lecture hall of our school.
Will you be available then? I am looking forward to your early reply. 【解析】
