My town 100 hundred years ago
My town was a small settlement hundred years ago. There were few shops, streets, transports. The people moved in carriages. There was one hospital and post office.
Day after day the settlement became better. The railway was constructed and a communication with other towns appeared there.
The settlement became a town. The people became more. The shops became more. The buses, the cars, a lot of shops appeared. The schools were built. New houses were built in the streets.

Мой городок был маленьким поселением 100 лет назад. Там было немного магазинов, улиц, транспорта. Люди передвигались в каретах. Там была одна больница и почта.
День за днём посёлок становился лучше. Была построена железная дорога и появилась связь с другими городами. Появились автобусы, машины, много магазинов. Были построены школы. На улицах были построены новые дома.
