1.There is nothing more possible than a new hip or knee that can put the spring back in your step.Patients receiving joint implants (移植) often are able to resume many of the physical activitiesthey love, even those as vigorous as tennis and hiking. No wonder, then, that joint replacement is growing in popularity.In the United States in 2007, surgeons performed about 806,000 hip and knee implants (the joints most commonly replaced), double the number of performed a decade earlier. Though theseprocedures have become routine, they are not failure free."Implants must sometimes be replaced," said Dr. Henrik Malchau, an orthopedic surgeon (矫正外科医生) at Massachusetts General Hospital in Boston. A study published in 2007 found that 7 percent of hips implanted in Medicare patients had to be replaced within seven and a half years."The percentage may sound low, but the finding suggests that thousands of hip patients eventually require a second operation," said Dr. Malchau. Those patients must endure additional recoveries,often painful, and increased medical expenses.The failure rate should be lower, many experts agree. Sweden, for instance, has a failure rateestimated to be a third of that in the United States. Sweden also has a national joint replacement registry, a database of information from which surgeons can learn how and why certain procedures go wrong. A registry also helps surgeons learn quickly whether a specific type of implant is particularly problematic. "Even country that has developed a registry has been able to reduce failure rates significantly," said Dr. Daniel Berry, chief of orthopedic surgery at the Mayo Clinic in Rochester, Minn.A newly formed American Joint Replacement Registry will begin gathering data from hospitals in the next 12 to 18 months. It's good news for those who are considering replacing a knee or hip.Why does Sweden have a lower rate of hip implant failure?

Passage Four

Sporting activities are essentially modified forms of hunting behavior. 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 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、（84）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 attack.

Then about ten thousand years ago, after this immensely long period of hunting the 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 ( 驯养 ) 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.

(85)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 sequences( 后果 ), but the aim of the operation was no longer to avoid starvation. Instead the sportsmen set off to test their skill against prey that was no longer essential to their survival. To be sure, the kill may have been eaten, but there were other purposes, much simpler of obtaining a meaty meal.What is the main idea of the passage?
