If we are attentive, we may find out, that there are a lot of things that we can do all around. The following activities could make our neighbourhood better and people’s life easier.
Carrying bags is a good way to help elderly people. It will be even better if you ask them what they need and go shopping yourself. There are some lonely pensioners in our neighbourhood.
They will also be happy if somebody helps them about the house. Cleaning the flat, washing up or repairing something is a good way to help them, too.

Если мы будем внимательны, мы можем обнаружить, что есть много вещей, которые мы можем сделать вокруг. Следующие мероприятия могут сделать наш район лучше и жизнь людей проще. Переноска сумок - хороший пожилым людям. Будет еще лучше, если вы спросите их, что им нужно, и отправитесь за покупками самостоятельно. В нашем районе есть одинокие пенсионеры. Они также будут счастливы, если кто-нибудь им по дому. Уборка квартиры, мытье посуды или ремонт тоже могут им.
Про серебро
Silver is a chemical element with atomic number 47 in the periodic system Mendeleev. The chemical formula of silver is Ag.
Silver was known as far back as the 4th millennium BC. This precious metal, like gold, is found in nature in the form of nuggets. Therefore, mankind met him without the help of scientists. In ancient Egypt, silver was called "white gold." It was harder to mine than gold. Therefore, in those days it was worth more than gold.
It is believed that silver received its Latin name argentum from the Greek argos - white, sparkling.
In nature, silver is found both in the form of nuggets, and in the form of rare minerals that are found in polymetallic ores - sulfides of copper, lead, zinc. Silver nuggets are quite heavy. It is known that the largest nugget weighed 13.5 tons.
Silver is a metal, and has all the properties of metals. But the chemical activity of silver is small. In a series of metal stresses, also called the electrochemical series of metal activity, silver is almost at the end.
Silver superbly conducts electric current and heat. In addition, it is able to withstand a tremendous load. Various contacts are made from it in devices used on comic missiles, nuclear installations, submarines, computer technology, etc.
The excellent reflectivity of silver allows it to be used in the manufacture of mirrors, telescopes, microscopes, and various optical instruments.
Silver is widely used in jewelry. Rings, brooches, dinner sets still adorn the life of a person. Coins are minted from silver.
