1. Recycling is a technology that helps protect the environment and cut down on usage of raw materials. The steel, paper and glass industries recycle a lot. The largest recycler is the steel industry. It recovers more than 70 per cent of its original materials. For example, since 1988 they have produced the majority of new metal cans from old ones. Metal parts for cars and planes are other examples of recycling steel. Fragments of waste glass are widely used in construction. For producing writing paper and pens, used packing boxes are an ideal material. They are cheap and easy to recycle. Nowadays more and more recycling centres are appearing in our towns and cities.

Nowadays solar energy is widely used as an alternative form of power. Solar panels transform the energy from the sun into electricity. The first plane that does not need fuel was constructed in France in 2015. It uses only the sun's energy. The panels are placed on the huge wings of the plane. It doesn’t fly very fast. Solar energy can make the plane move at only 140 miles an hour. However, the plane is able to travel round the world. It is safe and can successfully cross areas of bad weather. In the future, engineers hope to construct a model that people can fly in. Our dream of environmentally friendly transport may come true very soon. Would you like to take a flight on the solar plane?
We are always told that we should clean our teeth regularly to keep them healthy and to have fresh breath. It is believed that people started using a kind of paste to clean their teeth around 5000 years ago. However, the ingredients of these tooth powders were very different from ours. For example, the people of ancient Egypt used salt, mint, dried flowers and pepper to create tooth powder. Later, in the 18th century, in some countries in Europe, people brushed their teeth with burnt bread. The first toothpaste appeared in 1890, in Great Britain. At first it was sold in jars. Then special tubes were designed to make the toothpaste more comfortable to use.
