| It is a pleasure for me to write this letter to tell how much I enjoyed my stay in your whole family last week. This was my first visit to a English family. At first, I was worried about my poor English. And when I saw your wife and children waiting for me with warm smile of welcome on their faces. I immediately knew that everything would be all right. There are many more happy memories of a week that I will keep with me forever. I particularly enjoyed driving through the countryside with you and saw the changing colors of the leaves on the trees. I also like the fishing trip. It was such much fun. | 1. _____ 2. _____ 3. _____ 4. _____ 5. _____ 6. _____ 7. _____ 8. _____ 9. _____ 10. _____ |
