Dear Mary,

I am writing to express my sincere gratitude for the CET-4 (College English Test Band 4) preparation books you so kindly sent me. They have proven incredibly useful, especially in strengthening my reading comprehension and writing skills. To be honest, I had been looking forward to obtaining these materials for some time, so your thoughtful gesture arrived at exactly the right moment. Your considerate care has truly warmed my heart.
These days, I am fully dedicated to preparing for the upcoming Band Four examination. I’ve developed a systematic study plan aimed at completing the entire book before the test date. As the well-known saying goes, where there is a will, there is a way. So please rest assured—I am confident that I will succeed. Once the results are out, I will make sure to share the wonderful news with you!
I must take this opportunity to thank you once again for your great kindness.
Sincerely yours,
Tom
