第9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。

Human and the Earth

In terms of the evolution of life on Earth,human beings have just arrived.Despite their shori time on Earth,however,people have brought about enormous changes to the surface of the planet一changes far out of proportion to the interval of time they have occupied it.
People have more control over their surroundings than any other species on Earth.With the combination of intelligence and manual skill(allowing us to make and use tools),people have found ways to use plant and animal resources,mineral ores,fuels,and many other materials and resources from the Earth.
As the number of people on Earth increases,it becomes increasingly difficult for the population to survive on the resources of the land.The amount of land is limited.Although agricultural production can be increased by use of machinery such as tractors and the addition of fertilizer,the land ultimately can produce only so much food and no more.
As the human population grows,people consume more.Clearly,some locations on Earth already have too many people;in many of these areas,future increases will surely bring about more poverty and suffering. Yet people in rich nations use proportionally far more of the available resources than people in poorer nations.As they consume these resources without restraint,they also waste large amounts of them.
People are only a very small fraction of all the living things on the planet.Yet their numbers create a drain on resources that can't be renewed.For example,the amount of water on Earth is limited,this water is cleaned through natural processes.However,the natural processes for filtering water can clean only a certain amount of water by removing the pollution.Likewise,a limited amount of petroleum can be found under the Earth's surface.Petroleum is a valuable resource.Should people use it up to manufacture petrol for automobiles?As people work to control the planet and make life comfortable,are they using up resources that are needed for their survival?

Why have people more control over their surroundings than any other species on Earth?
A:Because of their intelligence and manual skill.
B:Because they can use plant and animal resources,mineral ores and fuels.
C:Because they are cleverer than any other animals on Earth.
D:Both A and B.

答案：D

解析：

文章第一段第一句话提到“就地球上生命的进化而言，人类是姗姗来迟者”，因此比较而言，人类的历史并不长。选项A是正确的。
从文章第二段第二句话“With the combination of intelligence and manual skill...”我们知道选项A和B都是正确的，因此选择D项。
文章第三段提到，土地的总量是有限的。虽然使用拖拉机等机械和施用化肥可以提高农业产量，但是土地最终所能产出的粮食只有那么多，不会再增加。因此只有选项C是正确的。
文章第四段第三句说富裕国家的人们所使用的能源在比例上远远大于贫穷国家的人们。选项C中提到的“发达国家的人们”最符合题意。
根据文章最后一段关于资源的描述我们可以发现选项A、B、C都是正确的，只有选项D的表述错误，因此选择D项。
