We can’t imagine our life without humour. Humour is our great friend and plays a very important role in our life. Humour makes us laugh and cry. Humour can help us to forget our troubles and to solve our problems. Humour makes our life easier, brighter and happier. The roots of humour lie in life itself. There are a lot of humorous writers in the world. The most famous are M.Twain, Jerome K. Jerome, St. Leacock, N. Gogol, M. Zoshchenko, I. Ilf and Ye. Petrov, Ya. Gashek and many others. They criticize and ridi- cule our faults. But good humour is humour without harm and without malice. Teacher : Johnny, why should we eat carrots? Johnny: Because carrots are good for our eyes.
