Anna arrived far too early. Usually she left things to the last minute， but today was a very special occasion. It was almost as if by getting there an hour beforehand she hoped to cause the plane to arrive sooner. Thoughts raced through her mind. “Do I look all right？ Will he notice that I'm wearing a new trouser suit？ Will he even recognise me？” After all， it was a year almost to the day since she had last seen Joe. She fished a mirror out of her handbag and inspected her face. Too much make-up？ Joe had never made any comment but she knew that he did not approve of heavy make-up. It was funny how much importance she attached to making a good impression on him. After all， friends do not judge each other by appearance. All the same， it was the first meeting after a long separation， and she wanted everything to go off right.
Looking out of the window， Joe caught a first glimpse， through a break in the clouds， of the town far below. This was his third visit， and looked like becoming an annual event. Certainly it was very flattering that they had invited him to be the guest lecturer at their Autumn Congress yet again. The Chairman of the Organising Committee， as a matter of politeness， had offered to meet him at the airport， as he had done on previous occasions. This time， however， it was not necessary， partly because Joe was quite familiar with the city， but mainly because Anna had said that she could take the afternoon off in order to come and meet him.

Today， Chinese cooking is famous all over the world， but of course it did not become famous suddenly. China's civilization is very ancient， and the art of cooking developed together with it over thousands of years.
In the distant past， our ancestors ate raw meat. They did not know how to cook their food. When they killed animals， they often did not even take the skin off them before they ate them. Some specialists believe that it was forest fires that first introduced man to the art of cooking. Forest fires were sometimes started by storms， and people ran away from the burning areas and returned when the fires had gone out. When they came back， they found that the animals which were caught in the fires and could not escape were “cooked”， and that the cooked meat tasted much better than raw meat . From this， man began to realize that cooking made his food more tasty. He discovered different methods of making a fire， and began to collect pieces of wood to burn.
Gradually， the cooking of food became a universally accepted idea. The Chinese word “peng” （from “peng tiao”， meaning the art of cooking）comes from the use of fire in cooking.
So， in this way people had learned how to cook their food. However， they still did not know how to flavour （调味） it.
How did man first learn to use salt on his food？
One theory is that many years ago some people who lived in a coastal area killed an animal on the seashore. They left the dead animal there for some time. The salt from the sea-water covered the animal and when， later， the meat was cooked， it had a very good taste. In time， man learned to collect salt to flavour his food. The word “ tiao” means “ flavouring ”， which began with the use of salt.
The discovery of cooking and flavouring played a very important part in the development of man and of human society. The fact that man no longer ate raw meat made him different from other animals. Cooking and flavouring killed bacteria（细菌）in food and made it more healthy. People began to eat meals at regular times of the day. Gradually， cooked food helped people to improve the condition of their minds and bodies， and finally it helped them to develop their productive abilities， and to move towards a state of civilization.
