单选题{{B}}练习八{{/B}} The competition among producers of personal computers is essentially a race to get the best, most innovative products to the marketplace. Marketers in this environment frequently have to make a judgement as to their competitors' role when making marketing strategy decisions. If major competitors are changing their products, then a marketer may want to follow suit to remain competitive. Apple Computer, Inc. has introduced two new, faster personal computers, the Mackintosh II and Mackintosh SE, in anticipation of the introduction of a new PC by IBM, one of Apple's major competitors. Apple's new computers are much faster and more powerful than its earlier models. The improved Mackintosh is able to run programs that previously were impossible to run on an Apple PC, including IBM-compatible (兼容的) programs. This compatibility feature illustrates computer manufacturers' new attitude of giving customers the features they want. Making Apple computers capable of running IBM computers and thus more popular in the office, where Apple hopes to increase sales. Users of the new Apple can. also add accessories (附件) to make their machines specialize in specific uses, such as engineering and writing. The new computers represent a big improvement over past models, but they also cost much more. Company officials do not think the higher price will slow down buyers who want to step up to a more powerful computer. Apple wants to stay in the high-price end of the personal computer market to finance research for even faster, more sophisticated computers. Even though Apple and IBM are major competitors, both companies realize that their competitor's computers have certain features that their own models do not. The Apple line has always been popular for its sophisticated color graphics (图形) , whereas the IBM machines have always been favored in offices. In the future, there will probably be more compatibility between the two companies' products, which no doubt will require that both Apple and IBM change marketing strategies.

单选题The UK is made up of four countries -- England, Scotland, Wales and Northern Ireland -- which have widely differing cultures and languages. Wales was the first country to fall under English control, in the late 16th-century. The Welsh were never actually defeated by the English. Instead, they realized that unity with their bigger neighbor was the only way to end the almost continuous state of war that existed between the two countries. Since unity, England and Wales have had the same systems of law, education and government. The situation between Scotland and England was very different. They fought fierce wars for centuries, each invading each other, whenever the situation seemed in their favour. This came to an end in the 17th-century when King James Vi of Scotland inherited the throne(王位) of England, after Queen Elizabeth I died without children. In 1707, Scotland and England were brought together in an Act of Union. This took away much of the Scots' control of their own affairs, but they kept their own systems of law and education. For the three countries, union resulted in peace. But England's occupation of Ireland has always been characterized by violence. Ireland was slowly brought under English control in the 16th- and 17th-centuries. But it retained its own government until 1801, when it was brought together with the Parliament at Westminster. However, Britain was under pressure to leave Ireland by 1920. In 1921, an agreement was signed whereby a separate Irish Free State (today called the Irish Republic) was created. This did not, however, include the six counties of Northern Ireland, which remain part of the "United Kingdom of Great Britain and Northern Ireland".

单选题{{B}}16-20{{/B}} Nonverbal (非语言的) communication has to do with gestures, movements and closeness of two people when they are talking. The scientists say that those gestures. movements and so on have meaning which words do not carry. For example, the body distance between two speakers can be important. North Americans often complain that South Americans are unfriendly because they tend to stand close to the North American when speaking, while the South American often considers the North American to be "cold" or "distant" because he keeps a greater distance between himself and the person he is speaking to. The "eye contact" provides another example of what we are calling nonverbal communication. Scientists have observed that there is more eye contact between people who like each other than there is between people who don't like each other. The length of time that the person whom you are speaking to looks at your eyes indicates the amount of interest he has in the things you are talking about. On the other hand, too long a gaze can make people uncomfortable. The eyes apparently play a great part in nonverbal communication. Genuine warmth or interest, shyness or confidence can often be seen in the eyes. We do not always consider a smile to be a sign of friendliness. Someone who is always smiling, and with little apparent reasons, often makes us uneasy.

单选题{{B}}26-30{{/B}} The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remains unconfirmed, but increasingly, experts are pointing the blame at portable electronic devices such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation (航空) industry, has recommended that all airlines ban (禁止) such devices from being used during "critical" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to individual airlines. And although some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights. The difficulty is predicting how electromagnetic fields might affect an aircraft's computers. Experts know that portable devices emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not. The fact that aircraft may be vulnerable (易受损的) to interference raises the risk that terrorists may use radio system in order to damage navigation equipment. As worrying, though, is the passenger who can't hear the instructions to turn off his radio because the music's too loud.

They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of travel in the foreseeable, future. The motorcar will undoubtedly change significantly over the next 30 years, It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types. Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One, proposed solution to this problem is the automated highway system. When the auto enters the. highway system, a retractable .(可伸缩的)arm. will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements. The driver will. use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer (蜂鸣器)that will warn of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present day highway.

单选题When Columbus reached the New World, com was the most widely grown plant in the Americas. This plant's range extended from what is now southern Canada to lower South America. At that time some tribes cultivated it at sea level, others at elevation(海拔高度) of more than 11 000 feet. "Columbus had no way of knowing that corn was far more valuable than the spices(香料) and gold he had hoped to find." said Frances B. King, a professor at a university of Pittsburgh. Through human intervention, this plant has developed into several hundred races, or varieties. Their heights vary from 2 to 12 feet, and their maturity ranges from little more than 2 months to almost a year. Their ears vary not only in color, but also in size. Unlike other cereals(谷类), corn bears little resemblance to its wild ancestors. In fact, it differs from the appearance of its immediate ancestors more than any other cultivated plant known. From humble origins as a lowland grass, corn developed into the western world's important grain. As its high yields allowed communities to grow far beyond what early agriculture could feed, most scientists viewed corn as having largely fueled pre-Columbian growth and civilization. Now, new findings are greatly altering researchers' notions about the time when com revolution occurred. New dates for its emergence from Mesoamenrica do not support the widely held view. The evidence now suggests that the signs of corn in Americas can date back 5 500 years at least.
