Subject: Request for Honorable Judging at the Upcoming English Speech Contest

Dear esteemed [Foreign Teacher's Name],

I hope this letter finds you in high spirits and good health. As a representative of the organizing committee, I am writing to humbly request your participation as a distinguished judge for our upcoming English speech contest.

This year's contest promises to be a thrilling showcase of our students' linguistic prowess and unique perspectives. We believe your expertise and profound understanding of the English language would be invaluable in evaluating their performances and providing insightful feedback. As Mark Twain once said, 'The right word may be effective, but no word was ever as effective as a rightly timed pause.' Your guidance, with its nuanced understanding of language, will not only help our students refine their speaking abilities but also inspire them to discover the power and beauty of effective communication.

Furthermore, your experience as an accomplished language professional will ensure a fair and unbiased judging process. Your discerning eye and insightful feedback, much like Ralph Waldo Emerson's belief that 'Speech is power: speech is to persuade, to convert, to compel,' will undoubtedly encourage and motivate the contestants to deliver their most compelling speeches.

Finally, your presence as a judge will bring a rich layer of cultural diversity to the contest. By evaluating speeches from diverse linguistic backgrounds, you will help cultivate an inclusive environment that celebrates the beauty and strength found in our differences, echoing Maya Angelou's powerful words: 'In diversity there is beauty and strength.'

The English speech contest will be held on [日期] at [时间] in [地点]. We understand your time is valuable and would be honored if you would consider joining us. Your presence would not only elevate the prestige of the event but, more importantly, inspire our students and foster their passion for English language acquisition.

Thank you for considering our request. We eagerly await your response and the honor of welcoming you as a distinguished judge to our English speech contest.

Sincerely,

[Your Name]
