Ответ:

1)Iron and steel.

We don't often use materials in their raw state. We change the raw materials to make the things we use every day.And the metal we use comes from a rock called an ore. We put the iron ore in a very big oven called a blast furnace. When the furnace is very hot, the metal in the ore changes into a liquid and comes out of the rock. The melted iron then goes into a diferent oven called a steel furnace. In this oven we make a metal called steel. It is stronger than iron. Next we put the liquid steel into a mould. A mould gives the steel a shape.
