Trademarks (商标) identify and distinguish the products of one business firm from those of another. It may include a word,a sentence,a name,a symbol,a picture,or any combination of these. Trademarks must be attached directly to the product. Many trademarks contain the name of the owner of the business. But manufacturers often use some word to describe the qualities of the product,or make up a word. The spoken part of a trademark is called the brand name.
Trademarks provide a simple way for people to determine who is responsible for a particular item. They also help people identify the brands they liked in the past so they may purchase them again. Manufacturers use trademarks to promote the sale of their goods.
Service marks also identify goods and services. They do not have to be attached to a product. Companies that provide services to the public,such as transportation companies,use these marks to advertise their services. For example,a blue sign with a bell,the symbol of the American Telephone and Telegraph Company,tells every passer-by that a public telephone is available for use.
Laws to protect the rights of the trademark owner were developed in the early 1800’s.Most countries now provide for regulation and registration of trademarks. An important protection for trademark rights is federal(联邦的)registration. In 1905,the U.S. Congress passed the first federal law on trademark registration to be held constitutional.

单项选择题
False teeth have been found in Italy in human heads that are over 2,500 years old. They were made of bone and set in gold. However,for hundreds of years afterwards,the apparent dental skill of those early people was lost. Without false teeth people looked old before their time,since so many lost their teeth at an early age.
Toward the end of the 17th century,rich people could buy false teeth made from ivory. The teeth were tied together with silk thread,but it was difficult to keep them in the mouth. That was why rich people would rather buy teeth from the poor who would often sell their teeth to buy food and clothing.
Early in the 18th century a French doctor used steel springs to hold teeth in place. However,it was difficult to close one‘s mouth! Late in the same century porcelain (瓷)teeth set in gold were often used to make false teeth.
Although the use of artificial teeth increased,human teeth continued to be used also. In the 19th century,teeth from soldiers killed in battle were made into artificial teeth. For example,teeth from the dead in the American Civil War were sent to England.
By the middle of the 19th century,an American doctor,Claudius Ash,invented a better kind of porcelain tooth made of a special kind of hard rubber.
