Passage Two:Questions 26 to 30 are based on the following passage.Sporting activities are essentially modified forms of hunting behaviour. Viewed biologically, the modern footballer is in reality a member of a hunting group. His killing weapon has turned into a harmless football and his prey (猎物) into a goalmouth. If his aim is accurate and he scores a goal, he enjoys the hunter’s triumph of killing his prey.To understand how this transformation has taken place we must briefly look back at our forefathers. They spent over a million years evolving (进化) as cooperative hunters. Their very survival depended on success in the hunting-field. Under this pressure their whole way of life, even their bodies, became greatly changed. They became chasers, runners, jumpers, aimers, throwers and prey-killers. They cooperated as skillful male-group attackers.Then about ten thousand years ago, after this immensely long period of hunting their food, they became farmers. Their improved intelligence, so vital to their old hunting life, was put to a new use—that of controlling and domesticating their prey. The hunt became suddenly out of date. The food was there on the farms, awaiting their needs. The risks and uncertainties of the hunt were no longer essential for survival.The skills and thirst for hunting remained, however, and demanded new outlets. Hunting for sport replaced hunting for necessity. This new activity involved all the original hunting sequencer but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that were no longer essential to their survival, to be sure, the kill may have been eaten, but there were other, much simpler ways of obtaining a meaty meal.第26题:The author believes that sporting activities ________.A) are forms of biological developmentB) are essentially forms of taming the preyC) have actually developed from huntingD) have changed the ways of hunting
