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 been 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".
Two 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 stimulus as the basis of their behavior.
Neither of these theories can 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 of the following statements would supporters of the" nature" theory agree with？
A．A person's instincts have little effect on his actions.
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.
Most physiologists deal with reduction. Phenomena are explained in terms of simpler phenomena. For example, the movement of a muscle is explained in terms of changes in the membrane of muscle cells, entry of particular chemicals, and interactions between protein molecules within these cells. A molecular biologist would "explain" these events in terms of forces that bind various molecules together and cause various parts of these molecules to be attracted to one another.
Like other scientists, physiological psychologists believe that all natural phenomena--including human behavior---are subject to the laws of physics. Thus, the laws of behavior. can be reduced to descriptions of physiological processes.
How does one study the physiology of behavior？ Physiological psychologists cannot simply be reductionists. It is not enough to observe behaviors and correlate them with physiological events that occur at the same time. Identical behaviors, under different conditions, may occur for different reasons, and thus be initiated by different physiological mechanisms. This means that we must understand "psychologically" why a particular behavior. occurs before we can understand what physiological events made it occur.
What does the passage mainly discuss？
A．The difference between "scientific" and "unscientific" explanations.
B．The difference between human and animal behavior.
C．How fear would be explained by the psychologist, physiologist, and molecular biologist.
D．How scientists differ in their approaches to explaining natural phenomena.
(1)假定其中一种产品实施配给。解释为什么消费者的境况可能变差。
(2)假定其中种产品被固定在当前市场价格以下的水平，因此消费者不能想买多少就买多少。你觉得消费者的境况是变好了还是变差了？
Draw a budget line and then draw an indifference curve to illustrate the satisfaction - maximizing choice associated with two products. Use your graph to answer the following questions.
a Suppose that one of the products is rationed. Explain why the consumer is likely lo be worse off.'
b. Suppose that the price of one of the products is fixed at a level below the current price. As a result, the consumer is not able to purchase as much as she would like. Can you tell if the consumer is better off or worse off？
Population tends to grow at an exponential(指数的)rate. This means that they progressively double. As an example of this type of growth rate, take one penny and double every day for one month. After the first week, you would have only 64 cents, but after the fourth week you would have over a million dollars.
This helps explain why the population has come on "all of a sudden". It took from the beginning of human life to the year 1830 for the population of the earth to reach one billion. That repents(缓慢进行)a time span of at least two million years. Then it took from 1830 to 1930 for world population to reach 2 billion. The next billion was added by 1960, only thirty years, and in 1975 world population reached 4 billion, which is another billion people in only fifteen years.
World population is increasing at a rate of 9000 per hour, 220000 per day, and 80 million per year. This is not only due to higher birth rate, but to lower death rate as well. The number of births has not declined at the same rate as the number of deaths.
Some countries, such as Columbia, Thailand, Morocco, Costa Rica, and the Philippines, are doubling their population about every twenty-one years, with a growth rate of 3.3% a year or more. The United States is doubling its population about very eighty-seven years, with a rate of 0.8% per year. Every time a population doubles, the country involved needs twice as much of everything, including hospitals, schools, resources, food and medicines to care for its people. It is easy to see that this is very difficult to achieve for the more rapidly growing countries.
This passage chiefly discusses______.
A．the growth of world population
B．one type of the exponential rate
C．the population problem of more rapidly growing countries
D．the possible ways of dealing with the rapid population growth
