英文自己介绍信

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,
