There are all kinds of trains in the world.There
There are all kinds of trains in the world.There are trains to carry people,and trains to carry animals or other things.There are fast trains and slow ones.Some trains go through hills.  In big cities,the main streets are usually very busy.So you can find trains on the rails under the ground or above the unimportant streets.They carry people quickly in and out of the cities.  Can a train run over the water?Yes,it can.There are many bridges over the rivers.The trains can easily run over the water.But it is not easy to build the bridges over the rivers.There are dining -rooms for people on the train.You may eat something in them on the way if you are hungry.Trains are useful to man.Many children have model trains.With the modern trains they can build their own rails and enjoy the wonderful world of trains.——六年级英语阅读题,
