Subject: Question Regarding Research Topic for "Modern European History"
Dear Professor Smith,
I hope this message finds you well. My name is Chen Wei, a second-year History student from your module on Modern European History.
I'm currently preparing for the final research essay (due 15 June), and I'd like to explore the topic of "The Impact of the 1968 Prague Spring on Eastern Bloc Diplomacy". While reviewing your lecture notes on page 24, I noticed a reference to Soviet-Czechoslovak negotiations that sparked my curiosity.
Could you kindly recommend 2–3 key academic sources (books or journal articles) that would provide deeper insight into this specific diplomatic dimension? I aim to avoid a broad overview and focus on negotiation tactics and their geopolitical implications.
Thank you very much for your time and guidance. I truly value your expertise.
Best regards,
Chen Wei

Subject: Invitation to the Annual International Culture Day
Dear Ms. Johnson,
I hope you’re doing well! I’m writing on behalf of the Student Union to warmly invite you to join our International Culture Day on 25 May, 3:00–6:00 PM in the Main Auditorium.
This year’s theme, "Bridges of Culture", encourages cross-cultural sharing through food, music, and short presentations. Your participation would be incredibly meaningful—students especially admire your insights into American campus life and would love to hear your perspective.
Would you be willing to give a 10-minute talk or demo a cultural activity? We’ll cover transportation and provide a small gift as a token of appreciation.
Please let me know by 15 May. Looking forward to your reply!
Warm regards,
Li Na
