Scientists think that many – perhaps most – animals cannot see colours. The world is black and white to them.
To find out if dogs could see colours, scientists gave dogs food every time they played a certain piece of music. The dogs got ready to eat only when they heard this piece of music. They did not get ready to eat when they heard other pieces of music.
Then the scientists gave the dogs food every time they showed them a certain colour. The dogs got ready to eat when they saw this colour. The scientists then showed the dogs another colour. Again the dogs got ready to eat. The colours were all the same to them.

Insects live everywhere on land but not in the ocean. There may be over 30 million different kinds of insects in the world although scientists have not studied all of them yet, and many have no names.
Insects are very important in the world. They pollinate plants and help to break up the ground. Although some insects can hurt people or plants, other insects kill these dangerous ones. Insects are the food of many other animals.

Some insects are not good for people. In Egypt, thousands of years ago, millions of locusts ate all the plants that were growing. There was no food for people to eat and many people died. In Africa today, locusts still do the same thing.
For most people the worst kind of insect is the cockroach. It is bigger than many insects and not easy to kill. People can get sick when cockroaches walk on their food. In hot countries there are cockroaches everywhere. Some people think if something happened and most animals died, cockroaches would be the only animals still living.

There were two McDonalds – Mac and Dick - and they were brothers. In 1948, they owned a restaurant in California. They liked working in the restaurant, but they got tired of the customers ordering so many different things to eat.
‘If we gave customers a smaller menu, we could make some of the food before they come, and they wouldn’t have to wait so long for their meals,’ said one of the brothers. The other brother agreed and added, ‘And if we made the customers come to the counter, we wouldn’t need any waiters or waitresses. We could also use plastic plates so there wouldn’t be any washing-up.’

The first McDonald’s restaurant had no seats for customers to sit on. This meant that people had to take their food away, and that no one had to clean up any tables after them.
The most successful McDonald’s business is in Hong Cong. The Hong Cong McDonald’s sells more hamburgers every day than any other McDonald’s anywhere in the world. McDonald’s restaurants are so successful because children love going to them. They like the food, and they like the toys and games they can get at McDonald’s.
