Have you ever wondered what our future is like? Practically all people【C1】______a desire to predict their future【C2】______. People seem inclined to【C3】______this task using causal reasoning. First, we generally【C4】______that future circumstances are【C5】______caused or conditioned by present【C6】______We learn that getting an education will【C7】______how much money we earn later and that swimming be yond the reef may bring an unhappy【C8】______with a shark. Second, people also learn that such【C9】______of cause and effect are probabilistic(概率)in nature. That is, the effects occur more often when the causes occur than when the causes are【C10】______, but not always.【C11】______, students learn that studying hard【C12】______good grades in most instances, but not every time. Science makes these concepts of causality and probability more explicit and【C13】______techniques for dealing【C14】______them more rigorously than does causal human inquiry. In looking at ordinary human inquiry, we need to【C15】______between prediction and understanding. Often, even if we don't understand why, we are willing to act【C16】______the basis of a demonstrated predictive ability. Whatever the primitive drives that【C17】______human beings, satisfying them depends heavily on the ability to predict future circumstances. The attempt to predict is often played in a【C18】______of knowledge and understanding. If you can understand why certain regular patterns【C19】______, you can predict better than if you simply observe those patterns. Thus, human inquiry aims【C20】______answering both' what' and 'why' questions, and we pursue these goals by observing and figuring out. 【C1】
