The entire assets of one of these huge families often amounted, in the beginning, to little more than an axe, a hunting knife, an auger, a rifle, a horse or two, some cattle and a few pigs, a sack of seed com and another of salt, perhaps a crosscut saw, and a loom. Those who moved first into a new region lived for months at a time on wild meat, Indian maize, and native fruits in season. Yet if they were poor at the beginning, they confidently expected that soon they would be rich.
In a way almost impossible to define to urban dwellers, a slice of ground suitable for farming represented not just dollars and cents, but dignity. The obsession brought shiploads of yearners (渴求者) every week to Boston, New York, Philadelphia, Baltimore, Charles Town and Savannah. It sent them streaming westward into the wilderness after their predecessors to raise still more children who wanted still more land.

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 .
Those who support the "nature" side of the conflict believe that our personalities and behavior. patter, ns 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 the 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.
According to the passage, people have wondered for a long time
A. why one is different from another
B. how one has certain personalities and behaviors
C. why one is more intelligent than another
D. why one is cooperative and another is competitive

Birth, marriage and death:these are the greatest events in human life. Many things, good and bad,can happen to us in our lives. (79) Yet there are three days which are usually marked by some kind of special ceremony : the day we are bom ; the day we get married and the day we die. These are the three main events in life. We only have a choice in the second of these: we can choose whether or not to marry. But we have no choice in birth and death. All human beings— from the most primitive to the most sophisticated—are affected by these three events. The only thing that differs in each society is the way these events are celebrated. Yet all societies share common characteristics. Birth is a time of joy. The proud parents receive congratulations and presents on behalf of the new-born. Marriage is also a time of joy. The young couple go through a special wedding ceremony and receive presents to help them set up their home. (80) Death is a time of sorrow and is marked by a special ceremony and mourning. The dates of all three events are usually remembered.
All human societies _________.
A.celebrate the three main events in life, but in different ways
B.are not affected by these three events
C.celebrate these three events in exactly the same way
D.are the same
