Dear Mr. Lee，
As I am leaving for New York immediately to pursue higher education， I shall be very grateful for a letter of introduction to your brother The-Sheng who， I u nderstand， is now studying at Columbia University. I like very much to make the acquaintance of him who， I understand， has sojourned in the United States for qu ite a number of years and knows that country very well. I am sure I shall benefi t immensely by his advice and guidance when I arrive at that American city， whic h is entirely strange to me .I plan to study at Columbia University during the f irst year of my stay in the United States and hope to approach your brother for detailed information regarding the entrance requirements of that institution if I can have the pleasure of meeting him.
With kind regards，
Yours sincerely，

Dear Mr. Johnson，
I take great pleasure in introducing Mary Brown one of my classmates and best friends to you. She is going to pursue her education as a postgraduate in your university after her graduation here. She and I had lived and studied together for four years. No friend deserves so much love and respect as she does. Now that we have finished our study here we had to part with each other.
Will you please give her some guidance in regard to the entrance examination? Any information you can provide， as well as your introduction for him to meet the future tutor shall be appreciated very much.
Yours truly，
Emma
