     During the weekend I traveled by the air for the first time in my life. I usual travel by train or bus. It's
both cheaper and safe. But to fly in the sky was something new to me. At the end I felt a little nervous.
But very soon I became exciting when I found me high up in the sky among the clouds. I also found that
mountains, fields, river and so on were interestingly small. I enjoy the frightening and comfortable journey
very much. After all, it is more interesting take a plane than to take a car.
