Marshall Field’s, a department store in Chicago, has long used the motto, “Give the lady what she wants.” Finding out what the customer wants is one of the problems marketing research tries to solve. Marketing research has been defined as trying to analyze marketing problems scientifically. It studies people as buyers and sellers, examining their habits, attitudes, preferences, dislikes, and purchasing power. It often studies specific groups of people, such as teenagers, high-income groups, or senior citizens. Marketing research also investigates distribution systems, pricing, promotion, product design, packaging, brand names, and almost every aspect of the seller-buyer relationship.

Marketing research is divided into a number of sub-areas. Advertising research attempts to find out the effectiveness of advertising. It also seeks to learn the best media for advertising specific products：television, newspapers, radio, magazines, billboards, and others. Market analysis tries to identify and measure markets for specific products and to estimate sales potential. Markets may be differentiated by population groups or by geography. Some types of clothing are more likely to sell in Florida and California than in the northern Midwest. Some cosmetics will appeal more to black customers than to white customers. Performance analysis helps a company learn how well it is meeting its goals of sales and profits. Product research analysis covers the whole area of new-product development. Marketing research is an expensive undertaking, and its costs are built into the prices of products.

　　　　　　　　　　　　　　　　 C

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.

　　 When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered trees.

　　 Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.

　　 Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.

　　 Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.

　　 The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.

　　 So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes.

　　 However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.

"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."

　　 But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.

　　 They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.

How the iron of tomorrow (the first Self Clean Iron) can change your lifestyle today?

General Electric introduces the iron of tomorrow．The iron can clean itself inside where irons get dirty．Because it cleans itself each and every time you empty it．How? With a push of a magic blue button．

The magic blue button

The first thing you’ll notice that’s different about this iron is the blue button on the side．It’s marked “Self Clean”．Push this blue button, and you can wash out loose mineral deposits(沉淀物) that remain and block up inside．Push this button, and you’ve made life a lot easier．

Less chance of brown spots

Sure, Self Cleaning Iron is going to cut down on brown spots (Those ugly spots that happen on nice, cleanly pressed clothes．) because a Self Cleaning Iron becomes clean each time you press that magic blue button．

Steams better longer

Common sense tells you that if you’ve got an iron that blocks less often it has to stay younger for a long period of time．In other words, it steams better longer．That’s another joy of owning General Electric’s Self Cleaning Iron．

What does it mean to you

Today you are doing so much more than just running a house and running after the kids．You’re working．You’re going to school．It’s all part of your lifestyle．The iron can change that lifestyle by giving you less trouble before you iron．If we can make it easier for you to be a better wife, a better mother, a better house-maker, we want to．The new Self Cleaning Iron is another one of Home-Makers from General Electric．
