How do you go to school or work? As everyone knows, there(be) different means of transportation (交通工具) in the world, bikes, buses, ships, trains and others.
If you are in big (city), like Shanghai or Beijing, maybe you get to school by subway, or you have to walk to school if you live in Mountain village. Here I am just (try) to say something about bikes.
Twenty years ago, bikes were kind expensive (昂贵的) in most villages. Every family just had one two bikes. Children got to school by bike; women rode bikes to go shopping. Then motorcycles began to become popular. People no longer (不再) rode bikes because motorcycles ran much faster. now, bikes are highly suggested (高度推荐) in some countries. They think buses, cars and motorcycles are bad for the air but bikes are (friendly) to the environment (环境). So to live a green life, (ride) a bike is a good way.
