    换个语序就可以了
    it is necessary to have at least a master's degree------a teacher in a university
    显然应该填to become
    这里的to become a teacher in a university 做主语，用becoming应该也可以，但题目中没有这个选项
    而CD中都有one，有sb的一般会有for出现，而题中没有，因此只能选A

  • 第6题：

    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.

    答案：D
    解析：
    本题考查的是细节理解。
    【关键词】if you fly to Milan from JFK and stop in Rome midway；how much
    【主题句】第3自然段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. 与之不同的是，也是8月5日下午10:05分乘坐意大利航空611次航班从纽约肯尼迪机场出发，中途经停罗马，终到米兰的经济舱往返机票为903美金。
    【解析】题目意为“根据例子，如果你要从纽约肯尼迪机场起飞，中途经停罗马，终到米兰需要花多少钱？”选项A意为“经济舱单程机票，752美金”，选项B意为“经济舱往返机票，1655美金”，选项C意为“经济舱单程机票，827美金”，选项D意为“经济舱往返机票，903美金”，根据主题句，
