5、Language is always changing. In a society where life continues year after year with few changes，the languages do not change either. The earliest known languages had difficult grammar but a small，limited vocabulary. Over the century，the grammar changed，and the vocabulary grew. For example，the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way，hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast，and language is changing fast too. There are several major (主要的) language families in the world. Some scientists say there are nine main families，but other scientists divided them differently. The languages in each family are connected，and scientists think that they came from the same parent language. About 3% of the people in the world speak languages that are not in these major families.统考英语阅读理解

题型描述: 阅读理解The old-fashioned general store is fast disappearing. This is, perhaps, a pity, because shopping today seems to lack that personal element which existed when the shopkeeper knew all his regular customers personally. He could, for instance, remember which brand of tea Mrs.Smith usually bought or what sort of washing-powder Mrs. Jones preferred. Not only was the shop a center of buying and selling, but also a social meeting place. A prosperous general store might have employed four or five assistants, and so there were very few problems in management as far as the staff were concerned. But now that the supermarket has replaced the general store, the job of the manager has changed completely. The modern supermarket manager has to cope with a staff of as many as a hundred apart from all the other everyday problems of running a large business. Every morning the manager must, like the commander of an army division, carry out an inspection of his store to make sure that everything is ready for the business of the day. He must see that everything is running smoothly. He will have to give advice. And make decisions as problems arise, and he must know how to get his huge staff to work efficiently with their respective responsibilities. No matter what he has to do throughout the day, however, the supermarket manager must be ready for any emergency that may arise. They say in the trade that you are not really an experienced supermarket manager until you have dealt with a flood, a fire, a birth and a death in your store.1、 6.
