1. One of Aesop's fables tells of a fox who wanted some beautiful, sweet-smelling grapes. The fox tried to get the grapes, but they were just a bit higher than he could reach. When the fox realized that he couldn't reach the grapes, he walked away. As he left, he told himself that the grapes were probably sour and that he really didn't want them.

3. Trolls have got bulging eyes, long mega-powerful arms, swollen noses and are covered all over in earth. They walk around with their mouths open. During the daytime they stay in their caves, but in the evenings they love to go out hunting people. At one time there were lots of them in Norway.

4. William Shakespeare gave his mother tongue many phrases and sayings, which English speakers still use every day. Often they do not realize these words come from Shakespeare's plays or poems. Since those times, English has continued to change. Settlers from Britain moved across the world taking their language with them.
