When the supply for a certain service is less than the demand on the market, the requirement by the importer to get a bond is much ______.A．easierB．more difficultC．more happierD．the same

第1题：

You may get consumers who want very high quality services satisfied, but at a higher price. And the people who want no-frills service and cheap product will also get it at the other end of the market. So competition allows a range of variety to occur in a market. The benefit to society of competition is that it makes a major contribution to the fundamental economic issue, which is the scarcity of productive resources. It means that on the production side, there is maximum pressure to conserve the use of those scarce productive resources. On the demand side it also rations consumer demand appropriately, and it also tends to mean that the variety of consumer needs can be met.

1. From the first paragraph of the passage we can know that usually there are ()kinds of consumers who may get satisfied in a market.

A. two

B. three

C. four

2. What does “it” in the first sentence of paragraph 2 refer to()

A. fundamental economic issue

B. the scarcity of productive resources

C. The benefit of competition

3. The sentence in paragraph 1“So competition allows a range of variety to occur in a market” means ().

A. competition makes the market supply various products and services

B. competition makes a lot of things occur in a market

C. competition makes different things occur in a market

4. On the demand side competition also ()appropriately.

A. meets consumer needs

B. makes consumer rational

C. makes consumer satisfied

5. The best title of this passage is ().

A. Fundamental Economic Issue

B. The Benefit of Competition

第4题：

Everyone knows airline pricing is based on supply and demand. Fares are mores 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 you 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 process become so obviously illogical it may be time to 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?
Why may prices for direct flights be higher according to the passage?

A. Because all people prefer the shortest route to their destination
B. Because airlines take advantage of people’s preference for direct flights
C. Because connecting flights may cause inconvenience
D. Because airlines charge customers different prices for the same product

答案：

解析：

细节题。根据文段定位“……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……”。B项符合，航空公司可以利用很对策略去增加自己的利润，当然可以抓住消费者心理那就是较短的时间到达目的地。答案A项太过于绝对化，故排除。答案C项的原因是说因为飞机联系比较不方便，文段说人们就是项今早到达目的地，所以航空公司是抓住了这个心理，故C项排除。D项仅仅是一方面，但并不是该题目的答案，排除。因此答案选B。

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：

细节题。根据文段定位“booked on April 30 Compare that to $903 for a round-teip economy ticket to Milan(stopping in Rome)leaving JFK……”。故答案D项符合文意。A项在文段的最后一句提到，航空公司一般不会这么做，排除。B项是没有经停罗马的价格。C项没有提到827这个机票的价格，故排除。因此答案选D。
