¡¡¡¡3. How many men would have considered the possibility of an apple falling up into the tree? Newton did because he was not trying to predict anything. He was just wondering. His mind was ready for the unpredictable. Unpredictability is part of the essential nature of research. If you don¡¯t have unpredictable things, you don¡¯t have research. Scientists tend to forget this when writing their cut and dried reports for the technical journals, but history is filled with examples of it. (99Äêpassage 5)

¡¡¡¡The author asserts that scientists __

¡¡¡¡ shouldn't replace "scientific method" with imaginative thought

¡¡¡¡ shouldn't neglect to speculate on unpredictable things

¡¡¡¡ should write more concise reports for technical journals

¡¡¡¡should be confident about their research findings

¡¡¡¡4.The vast consolidation within the rail industry means that most shippers are served by only one rail company. Railroads typically charge such ¡°captive¡± shippers 20 to 30 percent more than they do when another railroad is competing for the business. Shippers who feel they are being overcharged have the right to appeal to the federal government's Surface Transportation Board for rate relief, but the process is expensive, time consuming, and will work only in truly extreme cases.(2003Äêpassage 3µÚ3¶Î)

¡¡¡¡It can be inferred from paragraph 3 that

¡¡¡¡. shippers will be charged less without a rival railroad.

¡¡¡¡. there will soon be only one railroad company nationwide.

¡¡¡¡. overcharged shippers are unlikely to appeal for rate relief.

¡¡¡¡. a government board ensures fair play in railway business.

¡¡¡¡5. I believe that the most important forces behind the massive M&A wave are the same that underlie the globalization process: falling transportation and communication costs, lower trade and investment barriers and enlarged markets that require enlarged operations capable of meeting customer's demands. All these are beneficial, not detrimental, to consumers. As productivity grows, the world's wealth increases. (01Äêpassage 4)

¡¡¡¡According to the author, one of the driving forces behind M&A wave is _________.

¡¡¡¡£ÛA£Ýthe greater customer demands

¡¡¡¡£ÛB£Ýa surplus supply for the market

¡¡¡¡£ÛC£Ýa growing productivity

¡¡¡¡6. Many captive shippers also worry they will soon be his with a round of huge rate increases. The railroad industry as a whole, despite its brightening fortuning fortunes still does not earn enough to cover the cost of the capital it must invest to keep up with its surging traffic. Yet railroads continue to borrow billions to acquire one another, with Wall Street cheering them on. Consider the .2 billion bids by Norfolk Southern and CSX to acquire Conrail this year. Conrail's net railway operating income in 1996 was just million, less than half of the carrying costs of the transaction. Who's going to pay for the rest of the bill? Many captive shippers fear that they will, as Norfolk Southern and CSX increase their grip on the market. (03Äêpassage 3)

¡¡¡¡According to the text, the cost increase in the rail industry is mainly caused by

¡¡¡¡. the continuing acquisition.

¡¡¡¡. the growing traffic.

¡¡¡¡. the cheering Wall Street.
