People of different jobs do lots of things. Actually, doing a job means repeating some actions every day. Let's decide what the job may be when people do these actions: drill, fill, clean, extract.

1. Maths teachers drill pupils in counting. A builder drills holes in the wall.

2. A dentist fills your teeth with some material. A cook fills the cakes with cream.

3. Doctors must clean wounds to avoid infection. A cleaning lady is responsible for cleaning private houses, public buildings or offices.

4. A policeman can extract the information from some people. Sometimes doctors can extract small things from people's noses and ears. Dentists have to extract very bad teeth.
