Today we live in a world where GPS systems, digital maps, and other navigation apps are available on our smart phones. 1 of us just walk straight into the woods without a phone. But phones 2 on batteries, and batteries can die faster than we realize. 3 you get lost without a phone or a compass, and you 4 can’t find north, a few tricks to help you navigate 5 to civilization, one of which is to follow the land... When you find yourself well 6 a trail, but not in a completely 7 area, you have to answer two questions: Which 8 is downhill, in this particular area？ And where is the nearest water source？ Humans overwhelmingly live in valleys, and on supplies of fresh water. 9 , if you head downhill, and follow any H2O you find, you should 10 see signs of people. If you’ve explored the area before, keep an eye out for familiar sights—you may be 11 how quickly identifying a distinctive rock or tree can restore your bearings. Another 12 : Climb high and look for signs of human habitation. 13 , even in dense forest, you should be able to 14 gaps in the tree line due to roads, train tracks, and other paths people carve 15 the woods. Head toward these 16 to find a way out. At night, scan the horizon for 17 light sources, such as fires and streetlights, then walk toward the glow of light pollution. 18 , assuming you’re lost in an area humans tend to frequent, look for the 19 we leave on the landscape. Trail blazes, tire tracks, and other features can 20 you to civilization. 1.

icated technology and the rise of giant corporations.In addition, market forces have lost some of their significance as planning has become more important.The government has assumed a greatly changed role in the economy.Property relationships and decision-making power have shifted.The demand for highly educated specialists has increased enormously.

We may think of the American economy, as consisting of two completely different sectors.The world of the giant corporations, which can be called the "industrial system", consists of 500 or 600 firms that provide "nearly all communications, nearly all production and distribution of electric power, much transportation, most manufacturing and mining, a substantial share of retail trade, and a considerable amount of entertainment." Outside of this industrial system fall most agricultural enterprises, some mining and trucking, professional and artistic pursuits, some retail trade, and most personal and domestic services.

The classical economic laws of supply and demand still apply to some degree.But today the industrial sector is characterized far more by planning and certainty than by the free play of market forces.It appears that it could scarcely be otherwise.In large corporations with advanced technological systems and complex organizations of highly trained specialists, plans for producing any one item are made well in advance.Such plans, once made, are hard to change.Because long-term planning demands certainty, market forces are avoided by various means.For example, the corporation may achieve "vertical integration" by buying companies that supply raw materials at one end of the process and distribution outlets at the other.Corporations may agree on "just prices" for things they buy and sell.They may enter mutually advantageous long-term contracts with suppliers and customers.Moreover, in their quest for certainty they generally have the support of the state.

27.By the second paragraph, we know that .

A retail trade accounts for a big part in non-industrial system

B there are more giant corporations than agricultural enterprises

C giant corporations control every part of American economy

D giant corporations provide most of productions and services

28.From the whole passage, we can infer that American economy .

A is experiencing the rise of giant corporations

B is determined by hundreds of giant corporations

C has failed to balance supply and demand

D becomes highly-planned one

29.In the third sentence of last paragraph, the second "it" may refer to.

A classic economic law of supply and demand

B industrial sector

C American economy

D market force

30.Which of the following is not mentioned in the passage？

A American economy is characterized by high technology and giant corporations.

D Highly trained specialists are needed.

For thousands of years, people have known that the best way to understand a concept is to explain it to someone else. "While we teach, we learn," said Roman philosopher Seneca. Now scientists are bringing this ancient wisdom up-to-date. They're documenting why teaching is such a fruitful way to learn, and designing innovative ways for young people to engage in instruction. Researchers have found that students who sign up to tutor others work harder to understand the material, recall it more accurately and apply it more effectively. Student teachers score higher on tests than pupils who're learning only for their own sake. But how can children, still learning themselves, teach others？ One answer: They can tutor younger kids. Some studies have found that first-born children are more intelligent than their later-born siblings (兄弟姐妹). This suggests their higher IQs result from the time they spend teaching their siblings. Now educators are experimenting with ways to apply this model to academic subjects. They engage college undergraduates to teach computer science to high school students, who in turn instruct middle school students on the topic. But the most cutting-edge tool under development is the "teachable agent"—a computerized character who learns, tries, makes mistakes and asks questions just like a real-world pupil. Computer scientists have created an animated (动画的) figure called Betty's Brain, who has been "taught" about environmental science by hundreds of middle school students. Student teachers are motivated to help Betty master certain materials. While preparing to teach, they organize their knowledge and improve their own understanding. And as they explain the information to it, they identify problems in their own thinking. Feedback from the teachable agents further enhances the tutors' learning. The agents' questions compel student tutors to think and explain the materials in different ways, and watching the agent solve problems allows them to see their knowledge put into action. Above all, it's the emotions one experiences in teaching that facilitate learning. Student tutors feel upset when their teachable agents fail, but happy when these virtual pupils succeed as they derive pride and satisfaction from someone else's accomplishment. 1. What are researchers rediscovering through their studies？ A.Seneca's thinking is still applicable today. B.Better learners will become better teachers. C.Human intelligence tends to grow with age. D.Philosophical thinking improves instruction.
