单选题The ocean bottom—a region nearly 2.5 times greater than the total land area of the Earth —is a vast frontier that even today is largely unexplored and uncharted. Until about a century ago, the deep-ocean floor was completely inaccessible, hidden beneath waters averaging over 3,600 meters deep. Totally without light and subjected to intense pressures hundreds of times greater than at the Earth's surface, the deep-ocean bottom is a hostile environment to humans, in some ways as forbidding and remote as the void of outer space. Although researchers have taken samples of deep-ocean rocks and sediments for over a century, the first detailed global investigation of the ocean bottom did not actually start until 1968, with the beginning of the National Science Foundation's Deep Sea Drilling Project (DSDP). Using techniques first developed for the offshore oil and gas industry, the DSDP's drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean's surface and drill in very deep waters, extracting samples of sediments and rock from the ocean floor. The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983. During this time, the vessel logged 600,000 kilometers and took almost 20,000 core samples of seabed sediments and rocks at 624 drilling sites around the world. The Glomar Challenger's core samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to calculate what it will probably look like millions of years in the future. Today, largely on the strength of evidence gathered during the Glomar Challenger's voyages, nearly all earth scientists agree on the theories of plate tectonics and continental drift that explain many of the geological processes that shape the Earth. The cores of sediment drilled by the Glomar Challenger have also yielded information critical to understanding the world's past climates. Deep-ocean sediments provide a climatic record stretching back hundreds of millions of years, because they are largely isolated from the mechanical erosion and the intense chemical and biological activity that rapidly destroy much land-based evidence of past climates. This record has already provided insights into the patterns and causes of past climatic change—information that may be used to predict future climates.

单选题 Questions 61-64 are based on the following passage. "It's like being bitten to death by ducks." That's how one mother described her constant squabbles with her eleven-year-old daughter. And she's hardly alone in the experience. The arguments almost always involve mundane matters—taking out the garbage, coming home on time, cleaning up the bedroom. But despite its banality, this relentless bickering takes its adolescents—particularly mothers—report lower levels of life satisfaction, less marital happiness, and more general distress than parents of younger children. Is this continual arguing necessary? For the past two years, my students and I have been examining the day-to-day relation-ships of parents and young teenagers to learn how and why family ties change during the transition from childhood into adolescence. Repeatedly, I am struck by the fact that, despite considerable love between most teens and their parents, they can't help sparring. Even in the closest of families, parents and teenagers squabble and bicker surprisingly often—so often, in fact, that we hear impassioned recountings of these arguments in virtually every discussion we have with parents or teenagers. One of the most frequently heard phrases on our interview tapes is, "We usually get along but..." As psychologist Anne Petersen notes, the subject of parent-adolescent conflict has generated considerable controversy among researchers and clinicians. Until about twenty years ago, our views of such conflict were shaped by psychoanalytic clinicians and theorists, who argued that spite and revenge, passive aggressiveness and rebelliousness toward parents are all normal, even healthy, aspects of adolescence. But studies conducted during the 1970s on samples of average teenagers and their parents (rather than those who spent Wednesday afternoons on analysts' couches) challenged the view that family storm and stress was inevitable or pervasive. These surveys consistently showed that three-fourths of all teenagers and parents, here and abroad, feel quite close to each other and report getting along very well. Family relations appeared far more pacific than professionals and the public had believed.
