People have wondered for a long time how their personalities and behavior are formed. It is not easy to explain why one person is intelligent and another is not, or why one is cooperative and another is competitive.

Social scientists are of course extremely interested in these types of questions. They want to explain why we possess certain characteristics and exhibit certain behavior. 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 each other, and there is a great deal of debate between proponents of each theory. The controversy is often conveniently referred to as “nature and nurture”．

Those who support the “nature” side of the conflict believe that our personalities and behavior patterns are largely determined by biological 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 states that our behavior is predetermined to such a great degree that we are almost completely governed by our instincts(本能)．

Proponents of the “nurture” theory, or, as they are often called, behaviorists, claim 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 state that, like machines, humans respond to environmental stimuli (刺激) as the basis of their behavior.

Socially and politically, the consequences of these two theories are far-reaching. In the US，for example, blacks often score below whites on standardized intelligence tests. This leads some “nature” proponents to conclude that blacks are genetically lower in status than whites. Behaviorists, on the contrary, say that the differences in scores are due to the fact that blacks are often robbed of many of the educational and other environmental advantages that whites enjoy, and that, as a result, they do not develop the same responses that whites do.

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 and that the controversy will continue for a long time is certain.

Sydney—A shark savaged a schoolboy's leg while he was surfing with his father at a beach in Sydney on February 23．It was the third shark attack along the coast of Australia's largest city in a month．

The 15-year-old boy and his father were in the water off Avalon, on Sydney's northern beaches, around dawn when he was attacked．The city's beaches are packed with locals and tourists during the summer months．

"The father heard a scream and turned to see his son trashing （扭動(dòng)） about in the water," police said．"Fortunately, the shark swam away and the boy was helped to shore by his father．

Lifesaving Club spokesman Nick Miller: "It got him around the top of his left leg and the father came and dragged him out of water．" He said the boy was bleeding heavily when he was brought to shore．"There was a lot of pain, as you can imagine"．The teenager was airlifted to hospital for treatment for leg injuries．

Police said the bites" cut through to the bone" , but the boy did not appear to have sustained any fractures （骨折）．He was in a stable condition now．

Several beaches were closed after the attack．Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks．But they said it was too early to say what type of shark attacked the boy．"I don't even know if he saw it," Miller said．

Many shark species live in the waters off Sydney's beaches, but attacks on humans are still relatively rare．However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city's world-famous Bondi beach．

Fishermen say shark numbers are on the rise．There is a ban on commercial fishing in the harbor, which has increased fish stocks．Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to shore as they chase fish．Many shark species, including the Great White—the man-eater made famous in Steven Spielberg's Jaws—are protected in Australian waters．
