Помогите перевисти . И составить 5 вопросов. Robin Hood was a legendary hero who was well known and loved by the poor people of England. He lived in a forest far from the towns, and when the poor were oppressed by the rich, he helped them by giving them food and shelter. The sheriffs tried to arrest him but they did not succeed in doing so.
Once the sheriff of N. decided to organize a shooting contest in order to catch him because he knew Robin Hood to be a very good shot and was sure that he would take part in the contest by all means. The prize was a golden arrow.
On learning about the forthcoming contest Robin Hood gathered his men and discussed whether they should take part in it. Finally it was decided that although the risk of participating in the contest was great, they should all go, Robin Hood among them.
The day of the contest was fine and clear. The town was decorated with flags, and field for the contest was full of people. The sheriff looked for Robin Hood and his men everywhere. He knew that they were always dressed in green. To his disappointment, however, he could not find anybody who looked like them. The contest was won by a fellow dressed in red, who had come from a village with a whole company of young men.
After receiving the prize the fellow left the town, and nobody ever thought that it was Robin Hood. While leaving the town Robin Hood shot an arrow through the sheriff's open window. There was a paper attached to it with the following words: "Robin Hood thanks the sheriff for the Golden Arrow."
