Do some colours makes you feel calm while others give you energy? Scientists have studied the connection between colour and mood(心情) for a long time. Many believe that colour can influence our moods.

    Warm, bright colours such as yellow and red are positive colours. They can give people a pleasant feeling. Cool colours such as blue, purple, and green are relaxing colours. They help people experience calm feelings.

    Many public places are decorated(装饰) with certain colours in order to create certain moods. Orange makes people feel hungry, and many restaurants are painted in this colour.

    People use colour in their homes to create moods as well. Blue is a peaceful colour. It helps you rest, so it is a very good colour for a bedroom.

    Colours can also create bad moods. Some types of blue make people feel sad. Red can make people feel angry.

    What is your mood right now? Now look at the colour of the walls round you. Does it match your mood?

Some of the fast runners in the world are not very tall.  Some people are tall and some are short. The tallest man in the world is 2.41 meters tall. Today young people in many countries grow taller than their parents.This is because they eat better than their parents. Good food can help children grow.
