【正确答案】Dear David, Congratulations on getting a Ph. D in law. I know you''ve worked so hard in the past three years to get the degree, but where there is a will there is a way, you finally got what you want. I really feel happy for you. I believe your parents must be very proud of you, me too. Do you still remember our talk before you started working on your Ph. D? You said you would be a great lawyer one day, and now you''re approaching the success. Keep working and your dream will come true in the future. I believe it won''t take too long. By the way, I am going to Washington for a meeting next month. Can you show me around the city then? Congratulations again and please give my regards to your parents! Yours sincerely, Wang Lin
