Present the main points of the text in Russian. Don’t forget to show – when, how and where Morse code was invented and whether it is used now.

Write a paragraph in English describing the life of Samuel Morse and his first telegraph message.

If you think the invention of Morse code affects our lives today, say how. If it doesn’t, say why.

A pen is a writing instrument which applies ink to some surface. Pens may be categorized by the kind of tip on them. The main modern types are:

• ballpoint pens

• fountain pens

His ball-point pen, commonly called the “biro,” became popular in Great Britain during the late 1930s, and by the mid-1940s pens of this type were widely used throughout much of the world. The writing tip of a ballpoint pen consists of a metal ball, housed in a socket, that rotates freely and rolls quick-drying ink onto the writing surface. The ball is constantly bathed in ink from a reservoir, one end of which is open and attached to the writing tip.

The word used for ballpoint pens in Argentina is birome because Laslo Biro lived there for many years; also, biro can be used to refer to a ballpoint pen in British English. It was originally invented for the British RAF (Royal Air Force), as problems occurred with fountain pens due to the low air pressure aboard planes in flight. Ballpoint pens are still widely referred to as a
