Most adults can remember their first stuffed bear, and over the decades these toys have become nearly a symbol of their childhood. However, children are not the only ones with whom these toys have become popular, as many adults make it a habit to collect these toys as well. The Teddy Bear first became popular during the early 20th century and was associated with then President Theodore Roosevelt. The story can date back to a hunting trip that President Roosevelt had taken where he was invited to be the one to shoot a black bear that had been tied to a tree. Being a crazy outdoors lover and hunter, Roosevelt refused to kill the animal because he believed that shooting the helpless bear was unsportsmanlike and wrong. This story quickly spread through newspapers across the country, and in the end inspired the introduction of a stuffed toy called "Teddy's bear". These toys became popular soon after first introduced, and within ten years, they were being produced by dozens of companies around the world. Within a generation, these stuffed bears were "the" toy to have, and have always been within children's toy boxes ever since. They are most often mass-produced in factories in order to keep up with the high demand. However, there are still companies that take great pride in their handmade designs; and while handmade teddy bears are often preferred, they are also generally more expensive than their mass-produced ones. Today, these bears and other similar toys generate well over a billion dollars a year in profits for the companies that make them. Walk through just about any toy store in America and you will find dozens of different teddy bears lining the shelves. Question: Compared with mass-produced teddy bears, the handmade ones _ . Options: A: don't sell well B: are of high quality C: are more expensive D: are preferred by adults

Read the article and select the best answer. Article: The traditional distinction between products that satisfy needs and those satisfy wants is no longer adequate to describe classes of products. In today's prosperous societies, the distinction has become unclear because so many wants have been turned into needs.A writer, for instance, can work with paper and pencils. These are legal needs for the task.But the work can be done more quickly and efficiently with a word processor. Thus a computer is soon viewed as a need rather than a want. In the field of marketing, consumer goods are classed according to the way in which they are purchased.The two main classes are convenience goods and shopping goods.Two lesser types are specialty goods and unsought goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France(wine,for example)should be a specialty goods in the United States. People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought without enough thinking; someone has a sudden desire for an ice cream sundae on a hot day. Or they may be purchased as emergency items. Shopping goods are items for which customers search. They compare prices. quality, and styles, and may visit a number of stores before making a decision.Buying an automobile is often done this way. Shopping goods fail into two classes:those that are recognized as basically the same and those that are regarded as different. Items that are looked upon as basically the same include such things as home appliances, television sets, and automobiles.Having decided on the model desired, the customer is primarily interested in getting the item at the most favorable price. Items regarded as essentially... Question: Staples are items that _ . Options: A: are convenient to purchase B: are purchased without enough thinking C: people "want but don't need" D: people are in constant need of

Read the article and select the best answer. Article: Beavers are a very unique species in the world of nature and wildlife----they are architects. Their dams are fine examples of engineering. A pair of beavers will build a dam, using branches, mud and stones, across a river. The water held back by the dam flows over the bank on either side of the river, flooding the nearby ground and forming a pond. At some point in the pond the beavers then build their home, which is called a lodge. This consists of a cone-shaped pipe of branches and sticks of two to six feet in length held together with mud and stones, the top of which projects above the waterline. It serves as a shelter from the bad weather, a safety from enemies and a base for food supplies to be drawn upon in winter. From an engineering point of view the lodge could hardly be improved. Not only does it contain a central room just above water level, which is accessible only through underwater tunnels, but it also has "walls", one or more escape tunnels and an air hole at the top, which controls the temperature inside and gives air-conditioning. It is altogether a clever piece of construction, with all modern conveniences. It is, in fact, better protected against the effects of flooding than many human houses. Trees are essential to beavers. They eat the bark on the upper branches. But they must first _ the trees, using their four front teeth. With these sharp tools, it takes only a few minutes to cut down a tree. The engineering skill of beavers is to a large extent a result of their ability to use their front paws as hands. A female will carry her young held under her chin with her front paws, walking on her hind legs. A similar method is used by all beavers when transporting stones or mud, although they also carry such materials on their broad flat trails. The fore-paws are also used for digging and for dragging heavier pieces of wood. Question: This text is mainly about _ . Options: A: the beaver's lodge B: the beaver's engineering skills C: the beaver's dam D: the beaver's intelligence
