How nice to hear from you again.
Let me tell you something about the activity.
I’m glad to have received your letter of Apr. 9th.[/color]
I’m pleased to hear that you’re coming to China for a visit.
I’m writing to thank you for your help during my stay in America.
With best wishes.
I’m looking forward to hearing from you.
I’d appreciate it if you could reply earlier.
I sincerely hope this letter can draw your attention to the matter and I hope the problem mentioned above can solved as soon as possible。
I'm awfully sorry to hear that a horrible and severe earthquake unexpectedly hit your hometown. Faced with such a rarely-seen disaster, you remain so calm and strong-willed that we are all moved to tears. A friend in need is a friend indeed. Thinking about your present situation, we cannot wait a minute to make every bit of our effort to help you. I, as the chairman of student union, on behalf of all my schoolmates, express our most sincere pity and care for you. Besides, we make a donation of 120 thousand yuan to you, expecting that it can help you go through the difficulty. A better hometown can be rebuilt. Therefore, never give up whatever happens. Remember we won’t be far away when you need any help!
