1. We are not good economists yet. I am at the University today. My son is a student. I am not a mathematician. You are in the street now. John is in the garden now. Kate and Pete are not English. Does your friend an economist? My mother is not an expert. Do they from London?
2. At our factory there are psychologists. At my place there is no balcony. In New York there are a lot of high-rise buildings. There is a work which research of the nature and the reasons of welfare is called"people". In this work there is a certain sense. On a table there are books and there are no notebooks. On this street there are a lot of beautiful houses.
