Last Saturday, I wanted very much to see a film together with my brother after supper. On my way to the cinema, we happen to meet an American named Peter, who had lost his way, looked worried. When he told us that he wasn't able to find the hotel, we decided take him there. When we went to the hotel, we told of Peter the great changes that had taken place in our country in the past few year, and he told us a lot of things about the youths in the U.S.A.
Although my brother and I missed a interesting film, we felt very happily, for we had not only helped Peter out of trouble and also learnt something by him. （词数123）
