　　Complaining(抱怨)about faulty goods or bad service is never easy. Most people dislike making a fuss(大惊小怪). But if something you have bought is faulty or does not do what is instructed for it, you are not asking for a favor to get it put right. It is the shopkeeper's responsibility(负责) to take the complaint seriously and to replace or repair a faulty article or put right poor service, because he is the person with whom you have entered into an agreement. The manufacturer may have a part to play but that comes later.

　　Complaints should be made to a responsible person. Go back to the shop where you bought the goods, taking with you any receipt(发票)you may have. Ask to see the buyer in a large store. In a small store the assistant may also be the owner or you can complain directly. In a chain store ask to see the manager. If you telephone, ask the name of the person who handles your enquiry, otherwise you may never find out who dealt with the complaint later.

　　Even the bravest person finds it difficult to stand up in group of people to complain, so if you do not want to do it in person, write a letter. Stick to the facts and keep a copy of what you write. At this stage you should give any receipt numbers, but you should not need to give receipts or other papers to prove you bought the article. If you are not satisfied with the answer you get, or if you do not get a reply, write to the managing director of the firm, shop, or organization.

People have been painting pictures for at least 30,000 years. The earliest pictures were painted by people who hun??ted animals. They used to paint pictures of the animals they wanted to catch and kill. Pictures of this kind have been found on the walls of caves in France and Spain. No one knows why they were painted there. Perhaps the painters thought that their pictures would help them to catch these animals. Or per??haps human beings have always wanted to tell stories accord??ing to pictures.

About 5,000 years ago the Egyptians and other people in the Near East began to use pictures as a kind of writing. They drew simple pictures or signs to represent things and ideas, and also to represent the sounds of their language. The signs these people used became a kind of alphabet(字母表).

The Egyptians used to record information and to tell sto??ries by putting picture-writing and pictures together. When an important person died, scenes and stories from his life were painted and carved on the walls of the place where he was bur??ied. Some of these pictures are like modem comic-strip sto??ries. It has been said that Egypt is the home of the comic-strip. But, for the Egyptians, pictures still had magic power. So they did not try to make their way of writing simple. The ordinary people could not understand it.  

By the year 1,000 BC, people who lived in the area a-round the Mediterranean Sea had developed a simpler system of writing. The signs they used were very easy to write, and there were fewer of them than in the Egyptian system. This was because each sign, or letter, represented only one sound in their language. The Greeks developed this system and formed the letters of the Greek alphabet. The Romans copied the idea, and the Roman alphabet is now used all over the world.

These days we can write down a story, or record informa??tion, without using pictures. But we still need pictures of all kinds: drawings, photographs, signs and diagrams. We find them everywhere: in books and newspapers, in the streets, and on the walls of the places where we live and work. Pic??tures help us to understand and remember things more easily, and they can make a story much more interesting.
