Formal economic forecasting is usually based on a (1)_____ theory as to how the economy works. Some theories are complicated, and their application requires an elaborate (2)_____ of cause and effect. Others are relatively simple, (3)_____ most developments in the economy to one or two basic factors. Many economists, for example, believe that changes in the supply of money (4)_____ the rate of growth of general business activity. Others (5)_____ a central role to investment in new facilities—housing, industrial plants, highways, and so forth. In the United States, where consumers (6)_____ such a large share of economic activity, some economy believe that consumer decisions to (7)_____ or save provide the principal (8)_____ to the future course of the entire economy. Obviously the theory that a forecaster applies is of (9)_____ importance to the forecasting process; it (10)_____ his line of investigation, the statistics he will regard as most important, and many of the techniques he will apply.
Although economic theory may determine the general (11)_____ of a forecast, judgment also often plays an important role. A forecaster may decide that the circumstances of the moment are (12)_____ and that a forecast produced by the (13)_____ statistical methods should be modified to take account of special current circumstances. This is particularly necessary when some event outside the Usual run of economic activity has an a (14)_____ economic effect. For example, forecasts of 1987 economic activity in the United States were more accurate when the analyst correctly foresaw that the exchange value of the dollar would (15)_____ sharply during the year that consumer spending would slacken, and that (16)_____ rates would rise only moderately. None of these conclusions followed (17)_____ purely economic analysis; they all required judgment as to future decisions (18)_____, an economist may decide to adjust an economic forecast that was made by traditional methods to take account of other unique (19)_____; he may, for example, decide that consumers will (20)_____ their spending patterns because of special circumstances such as rising price of imports or fear of threatened shortages.
A．specific
B．peculiar
C．unique

Social scientists are, of course, extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behaviors. There are no clear answers yet, but two distinct schools of thought on the matter have developed. As one might expect, the two approaches are very different from one another, and there is a great deal of debate between proponents of each theory. The controversy is often referred to as "nature/nurture".
Those who support the "nature" side of the conflict believe that our personalities and behavior. patterns are largely determined by biological and genetic factors. That our environment has little, if anything, to do with our abilities, characteristics, and behavior. is central to this theory. Taken to an extreme, this theory maintains that our behavior. is predetermined to such a degree that we are almost completely governed by our instincts.
Proponents of the "nurture "theory, or, as they are often called, behaviorists, claimed that our environment is more important than our biologically based instincts in determining how we will act. A behaviorist, B.F. Skinner sees humans as beings whose behavior. is almost completely shaped by their surroundings. The behaviorists' view of the human being is quite mechanistic; they maintain that, like machines, humans respond to environmental stimuli as the basis of their behavior.
Either of these theories cannot yet fully explain human behavior. In fact, it is quite likely that the key to our behavior. lies somewhere between these two extremes. That the controversy will continue for a long time is certain.
Which one of the following statements would supporters of the "nature" theory agree with？
A．A person's instincts have little effect on his action
B．Environment is important in determining a person's behavior. and personality
C．Biological reasons have a strong influence on how we act
D．The behaviorists' view correctly explains how we act
Thanks to its simplicity .and measurability, electromagnetic induction is still the technology of choice among many of the remaining companies in the wireless-charging arena. But, as Splashpower found, turning the theory into profitable practice is not straightforward. But lately there have been some promising developments.
The first is the formation in December 2008 of the Wireless Power Consortium, a body dedicated to establishing a common standard for inductive wireless charging, and thus promoting its adoption. The new consortium’s members include big consumer-electronics firms, such as Philips and Sanyo, as well as Texas Instruments, a chipmaker.
Fierce competition between manufacturers of mobile devices is also accelerating the introduction of wireless charging. The star of this year’s Consumer Electronics Show held in Las Vegas was the Pre, a smart-phone from Palm. The Pre has an optional charging pad, called the Touchstone, which uses electromagnetic induction to charge the device wirelessly.
As wireless-charging equipment based on electromagnetic induction heads towards the market, a number of alternative technologies are also being developed. PowerBeam, a start-up based in Silicon Valley, uses lasers to beam power from one place to another.
It now seems to be a matter of when, rather than if, wireless charging enters the mainstream. And if those in the field do find themselves languishing in the disillusionment, they could take some encouragement from Faraday himself. He observed that “nothing is too wonderful to be true if it be consistent with the laws of nature.” Not even a wirelessly rechargeable iPhone.
Why is wireless recharging a depressing promise for experienced observers of the electronics industry？
A．It is not easy to put the theory into profitable production.
B．Wireless recharging needs new theories besides Faraday’s.
C．Wireless recharging can’t make profit for businesses.
D．It is hard to challenge the monopoly of Splashpower.
In Copernicus'time people still believed that all things—the sun, the stars, and the planets moved around the earth. It was an old belief that few men had ever questioned. Aristotle had based his theory of astronomy on this belief. Because the Church had long been the center of learning, the theory was also linked to religious beliefs.
In 1506 Copernicus returned to his homeland. A few years later he began to work for the Church. All those years Copernicus carried on his work in astronomy. He had just the most basic equipment and, like other scientists of his day, made observations with only his eyes. Still, using mathematics and logic, Copernicus worked out a different theory, which held that the planets went around the sun.
Copernicus did not announce his ideas. He did not want to make trouble. But he could not hide the scientific truth. So he talked about his theory with his friends, who strongly advised him to have his work published. His great book, on the Revolutions of the Heavenly Bodies, appeared at the very end of his life. Copernicus saw the first copy on the day he died, May 24, 1543.
Which of the following is true about Copernicus？
A．He had two brothers and a sister.
B．He used to be called Niklas Koppernigk.
C．He lost his father soon after he was born.
D．He spent 10 years at the University of Cracow.

In order to predict the relationship between independent and dependent variables, many scientific theories make use of what are called intervening variables. Intervening variables are purely theoretical concepts that cannot be observed directly. To predict the flight of a ping-pong ball, Newtonian physics relies on a number of intervening variables, including force, mass, air resistance, and gravity. You can probably anticipate that the intervening variables of biorhythm theory are the three bodily cycles with their specified time periods. It should be emphasized that not all psychological theories include intervening variables, and some psychologists object to their use precisely because they are not directly observable.
The final major component of a scientific theory is its syntax, or the rules and definitions that state how the independent and dependent variables are to be measured, and that specify the relationships among independent variables, intervening variables, and dependent variables. It is the syntax of biorhythm theory that describes how to use a person's birthday to calculate the current status of the three cycles. The syntax also relates the cycles to the dependent variable, performance, by stating that positive cycles should cause high levels of performance whereas low or critical cycles should cause low performance levels. To summarize, the components of a scientific theory can be divided into four major categories: independent variables, dependent variables, intervening variables, and syntax.
Based on the passage, causality may have the meaning that ______.
A．cause and effect can be independent of each other
B．there is hardly anything that happens without a cause
C．dependent and independent variables affect each other
D．cause and effect may vary respectively in most events
