Ⅳ. Reading Comprehension (75 points)Directions: There are five reading passages in this part. Each passage is followed by five questions. For each question there are four suggested answers marked A, B, C and D. Choose the best answer and blacken the corresponding letter on the answer sheet.Passage OneEarly in November 1965, New York was blacked out by an electricity failure (停电). The Mayor promised that it would not happen again. Pessimists (悲观主义者) were certain that it would happen again within five years. In July 1977, there was a repeat performance which produced a serious disorder throughout the city. At that time the city was in one of its worst heat waves.In 1965, there was little crime during the darkness, and fewer than a hundred people were arrested. In 1977, hundreds of stores were broken into and looted (劫掠). Nearly 4,000 people were arrested but far more disappeared into the darkness of the night. The number of policeman available was far from enough and some looters even carry guns.Hospitals had to treat hundreds of people cut by glass from shop windows. Banks and most business remained closed the next day. The blackout started at 9:30 P.M., when lightning hit and knocked out supply cables. Many stores were thus caught by surprise. For twenty-four hours, New York realized how helpless it was without electricity.31. According to the first paragraph, who were right: the authorities or the pessimists?A. The authorities.B. The pessimists.C. Both.D. Neither.

资料：Everyone knows airline pricing is based on supply and demand. Fares are more expensive during peak travel seasons like summer and to prime destinations like European capitals. So if a flight to Rome costs more than a flight to Milan, you'd think that demand for Rome must be higher or supply lower.What's puzzling is that you can pay a high price to a given destination but a dramatically lower price for the exact same flight if you agree to go on to another destination.Take Alitalia to Rome, for instance, for travel in August. A round-trip, economy flight directly to Rome leaving JFK at 10:05 p.m. on Alitalia 611 on August 5 costs $1,655 when booked on April 30. Compare that to $903 for a round-trip, economy ticket to Milan （stopping in Rome） leaving JFK on the exact same Alitalia 611 flight at 10:05 p.m. on August 5. So why is Alitalia willing to fly to Rome for $752 less than it would otherwise, plus give you an extra one-and-a-half-hour flight to Milan?Airlines have increased their profitability in recent years by segmenting the market for air travel and charging customers different prices for the same product. In this case, the market is segmented based on demand for direct flights. Airlines know most people prefer the shortest route to their destination, so they make customers pay up for the privilege of flying direct. （They also make it a little more inconvenient if you don't pay up for a direct flight, in order to encourage you to fly direct.）When prices become so obviously illogical, it may be time to revisit why air tickets can't be transferred or resold just like any other normal product. If the airlines are entitled to exploit the free market, shouldn't customers be allowed to do the same thing?According to the example, how much should you pay if you fly to Milan from JFK and stop in Rome midway?A.$752 for a one-way, economy ticket.B.$1,655 for a round-trip, economy ticket.C.$827 for a one-way, economy ticket.D.$903 for a round-trip, economy ticket.
