I took a trip to China a few months before. It was a wonderful experience where is beyond description. We spent three weeks visit Beijing, Shanghai and several other tourist attraction. The closer we approached the center of China, the much I liked it. Then we went to Hong Kong last week, which I think is different with Beijing. It is noisiest place I have ever seen. And another thing that give me a deep impression was the people in China—they were so much friendly. Anyway, the trip itself was interested. I can't wait to flying to China again.

Dear Mr. Black,
I’m very thank to you for inviting me to stay with you in the come summer vacation. I have been dreamed of seeing you again so that I can get help from you in my English learning. And I’m afraid I cannot go to your place in this summer. I’ve promised my grandmother, she lives in the country, to spend this summer with her. She misses me too much that I find difficult to refuse her request. I’m busy preparing for my examinations in present. I planned to visit you in winter if it’s convenient to you.
