1、大学英语四级考试试卷I. Reading Comprehension (30%)Passage OneE-business requires instantaneous decision-making and KM (knowledge management) has a tremendous role to play in achieving this as well as quality feedback. Real-time business without proper knowledge and feedback information quickly turns into real
2、-time unsupervised and valueless chaos. Lack of adequate knowledge flow and coherent real-time views of a situation inevitably lead to disastrous consequences. The infamous Barings Bank operated a real-time futures business without real-time checks and balances, and did not ensure adequate quality o
3、f knowledge flows from the trading floor to controllers and managers. It was too-much-too-fast coupled with too-little-quality-feedback and insufficient understanding. There was too little real-time knowledge at hand and it turned out a spectacular disaster.The missing link was KM. No serious e-busi
4、ness effort should be undertaken without considering, planning and implementing a strong KM infrastructure. Real-time knowledge must flow from those who have it to those who must be able to make the right move at the right time. And there is no time to spare. E-businesses must be equipped with inter
5、active workflow tools and real-time business intelligence feedback in a clear and understandable format. People involved must have access to all underlying documents at all times at a snap of their fingers. Otherwise, they will guess rather than make informed decisions.Or worse, in fear of making a
6、huge mistake, people will make no decisions at all. Take a home loan application process for example. You would most likely apply to a number of banks at the same time. They would obviously compete on pricing, but the bank that can make your credit assessment first and most effectively, process the
7、documentation and inform you on the progress every step of the way will get your business. The rest may be stuck with less demanding, more risk-prone customers. This may affect their overall profitability, and ability to compete on price and service in the future. It could put them out of business a
8、ltogether. So is there a link between e-business and KM? I surely think so.1. According to the passage, in doing E-business, you must _.A. make quick decisionsB. learn many disciplinesC. work hardD. know how to promote yourself2.

Stillman, a marine biologist at Stanford University, tested the heat tolerance of four species of crab
12、s found in the shallow waters of the Pacific Ocean.Two of the crab species were from the Oregon coast and lived in waters that range from 47 degrees to 59 degrees in temperature. The other two came from the Gulf of California in Mexico and thrived in waters of 54 degrees to 86 degrees. Live specimen
13、s of the animals were placed in aquariums (鱼缸) which were held at a constant temperature just at the upper thermal range of their natural habitat. The crabs were then outfitted with sensors that measured heartbeat.The temperatures were raised in the individual aquariums by about a fifth of a degree
14、a minute until the animals heartbeat stopped. This established the upper thermal tolerance limit for each of the species.The Mexican crabs that lived in the hottest climate were the least able to adapt to an increase in temperatures above that which they normally encounter in their natural home. Tem
15、peratures in the habitat of one of the crabs often reaches 105.8 degrees F, but the animals died at 106.2, less than a degree above normal. One of the Oregon species was acclimated to a temperature of 65, but survived until the aquarium temperature reached 87.The crabs that came from the Oregon coas
16、t adapted best to a rise in temperature and had the greatest capacity to increase their heat tolerance.6. The crabs from the _ can survive in waters with higher temperature.A. Oregon CoastB. Atlantic OceanC. Gulf of California in MexicoD. State of California7. The researchers studied the crabs to fi
17、nd out _.A. their heat toleranceB. their heart beatsC. their living stylesD. the differences between two species of crabs8.

The Oregon crabs _.A. lived in a hotter climateB. died at 106.2, less than a degree above normalC. only died at 87D. had greater capac
19、ity to increase their heat tolerancePassage ThreeScience and technology are productive forces. The scientific and technological revolution has played a very important role in the high-speed development of the economies of western countries including the United States since the war.Right before the e
20、nd of the war, the U.S. achieved prominent breakthroughs in the three fields of atomic energy, electronic computers and space navigation.

21、 great scientific and technological revolution in mans history.

22、nto the sky in 1957, the U.S. launched her earth satellite into the orbit. Then the U.S. started an unprecedented Apollo program, with the aim of sending man to the moon within a decade. The project was successfully carried out and in 1969, for the first time in mans history, two human beings landed
23、 on the moon. It was the most remarkable triumph in the twentieth century.Science has been greatly responsible for the rise on big business, as it has given industry certain technological advances, such as assembly-line production, automation. Since World War, the computer has produced major changes
24、 in our way of doing things. Computers have also helped social scientists to take a more experimental view of humans and their universe.11.
