　　 Advertising is a highly developed twentieth-century industry. The development of radio, television, cinema, magazines and newspapers has gone hand in hand with the development of advertising. Why is advertising so popular? Is it a waste of money? It has been proved again and again that ?repeated advertising increases product sales. Since it increases production, the price can be reduced. Therefore advertising, instead of making a product more expensive, makes it cheaper.

Advertising is now a scientific business. Once managers would say jokingly, " I know that half of what I spend on advertising is wasted, but I don't know which half." Now, all parts of an advertising programme are properly measured and researched.

What makes a good advertisement? There have been major changes in advertising in the past sixty years.. People read advertisements partly for information and partly for pleasure. Today's advertisements often start with a question, or a puzzle, with the purpose of attracting the reader's attention. Of course, most advertisements contain information. But this is usually contained in a text that is interesting and often funny. Humour is very important. Sometimes advertisements tell a story, or the story may be continued over a number of advertisements. However, there is a danger in this. It is possible that the reader or viewer will remember the advertisement but not the name of the product.

　 　Killer bees started in Brazil in 1957. A scientist in Sao Paulo wanted bees to make more honey. So he put forty-six African bees with some Brazilian bees. The bees bred and made a new kind of

bee. But the new bees were a mistake. They did not want to make more honey. They wanted to attack. Then, by accident, twenty-six African bees escaped and bred with the Brazilian bees outside.

　 　Scientists could not control the problem. The bees spread. They went from Brazil to Venezuela. Then they went to Central America. Now they are in North America. They travel about 390 miles a year. Each group of bees, or colony (群体), grows four times a year. This means one million new colonies every five years.

　 　Why are people afraid of killer bees? People are afraid for two reasons. First, the bees sting (刺痛、蜇) many more times than a normal bee. Killer bees can sting sixty times a minute non-stop for two hours. Second, killer bees attack in groups. Four hundred bee stings can kill a person.

　 　Already several hundred people are dead. Now killer bees are in Texas. In a few years they will spread all over the United States. People can do nothing but wait.

The greatest recent changes have ,been in the lives of women ,During the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman marrying at the end of the 19th century would probably have been in her middle twenties ,and would be likely to have seven or eight children, of whom four or five lived till they were five years old ,By the time the youngest was fifteen ,the mother would have been id her early fifties and would expect to live a further twenty years ,during which custom ,chance and health made it unusual for her to get paid work, Today women marry younger and have fewer children Usually a woman ‘s youngest child will be fifteen when she is forty－five and is likely to take paid work until retirement at sixty Even while she has the care of children ,her work is lightened by household appliances (家用电器)and convenience foods.

This important change in women’s way of life has only recently begun to have its full effect on women’ s economic position Even a few years ago most girls left school at the first opportunity and most of them took a full－time job However ,when they married ,they usually left work at once and never returned to it ,Today the school－leaving age is sixteen ,many girls stay at school after that age ,and though women tend to marry younger ,more married women stay at work at leas until shortly before their first child is born Very many more after wads ,return to full or part-time work Such changes have led to a new relationship in marriage ,with both husband and wife accepting a greater share of the duties and satisfaction of family life, and with both husband and wife sharing more e-qually in providing the money and running the home ,according to the abilities and inter-est of each them.
