I’m greatly honored to extend, on behalf of all the teachers and students , our warm welcome to Professor David.

I’m sure Professor David’s visit will promote the friendly relationship between our two departments.

All of us will benefit a lot from their visit.

I’m sure he’ll give us much valuable advice in our research.

Finally I hope Professor David will enjoy his stay in China.

（欢送词）

I have the honor to speak on behalf of my classmates at this farewell party for Mrs. Smith.

Mrs. Smith came to our school from America in September, 1999.

In the past four years, she’s always been kind to us, patient with us and strict in her work.

She gave such interesting and lively classes that every one of us enjoyed them very much.

Mrs. Smith. is leaving us for her hometown soon.

Now please allow me to express our hearty thanks to her successful work and wish her good health and a pleasant journey.

How time flies!

Two years have passed since Mr. Smith came to teach us English.

When you return to your country, we all hope you will keep in touch with us.

Thank you for giving us such a warm welcome.
