内容需包括以下方面：
1. 哪一种是你最喜欢的交通方式； 2. 阐述你的理由。
With the advent of modern technology, the means of transportation has become various. Bike, car, train, and plane are becoming the basic needs of people today. Among these various kinds of transportation, I would prefer bikes.
When time is not the first thing to be considered, I always choose bike to go to school. It is not only environmentally friendly but also avoids the more and more heavy traffic in the city now. Besides, riding bike is a kind of efficient practice which is very good to our health. So, here I’d like to appeal for all those possible to ride bike to school or office for our health, for the environment and for the city transportation.
