1.Passage FourClimate, more than any other single factor, determines the distribution of life on earth. Climatic boundaries establish the limits which organisms can survive. Plants, even more than animals, must be well adapted to climate in order to survive. They cannot move about or take shelter but must be equipped to endure whatever weather conditions are likely to occur. In the harsh conditions of the tundra, for example, low growing mosses, lichens, and a few flowering plants all hug the ground for shelter from icy winds.Animals, despite their ability to move about and find shelter, are just as much influenced by climate as plants are. Creatures such as the camel and the penguin are so highly specialized that they have an extremely limited distribution Others, such as bears are flexible enough to adapt to a broad range of climates. Oceandwelling organisms are just as sensitive to climatic changes--in this case temperature and salinity--as land animals. Reef corals can survive only in clear warm seawater. Certain foraminifers are so sensitive to changes in their environment that their presence can be taken as an index of sea temperature. Human beings are among theleast specialized of all animals and can live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.According to the passage, plants on the tundra grow in the ground__________.

There is nothing more possible than a new hip or knee that can put the spring back inyour step.Patients receiving joint implants(移植）often are able to resume many of thephysical activities they 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 performed a decade earlier.Though these procedures have become routine,they are not failure free.

implants must sometimes be replaced,said Dr.Henrik Malchau,an orthopedic surgeon(矫形外科医生）at Massachusetts General Hospital in Boston.A study published in2007 found that 7 percent of hips implanted in Medicare patients had to be replaced withinseven 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 rate estimated to be a third of that in the United States.Sweden also has a national jointreplacement registry,a database of information from which surgeons can learnhow and why certain procedures go wrongA registry also helps surgeons learn quickly whethera specifictype of implant is particularly problematic,"Every country that has developed aregistry has been able to reduce failure rates."

“Significantly,"said Dr.Daniel Berry,chief of orthopedic surgery at the Mayo Clinicin Rochester,Minn.

A newly formed American Joint Replacement Registry will begin gathering data fromhospitals in the next 12 to 18 months.It's good news for those who are considering replacing a knee or hip.1.What is the problem with hip or knee replacements in the U.S.?（）

12.Whatever you do, don’t challenge a chimpanzee named Ayumu to a number memory game. In 2007, Ayumu became famous for his lightning speed at a game that goes like this: A player views a computer screen where the numbers 1 through 9 appear briefly at once and then turn to white squares.The player then taps the squares where the numbers had been, in order from 1 to 9.People can do it.But no human competitor has ever completed the game faster or more accurately than Ayumu the chimp.For almost five years Ayumu remains undefeated.Psychologist Nicholas Humphrey of Darwin College at Cambridge University in England now thinks he knows the secret behind the chimp’s ability.Humphrey suspects Ayumu’s brain may have a condition that allows the chimp to see numbers as colors.This would mean that Ayumu may see a color glow after the numbers disappears.Then, instead of remembering the numbers, he remembers a sequence of colors, each associated with a number.The condition that Humphrey believes Ayumu may have is called synesthesia.Humans withsynesthesia may associate numbers and letters with colors.For example, a person may see thenumber “5” as the color blue.Until now, scientists had assumed only humans could havesynesthesia.Humphrey found the inspiration for his idea at a 2011 scientific conference.There, he heard apresentation about Ayumu’s memory abilities and another talk about synesthesia.He then put the two ideas together.Not everyone is convinced that Humphrey is correct.Primatologist Tetsuro Matsuzawa of thePrimate Research Institute at Kyoto University in Japan has spent decades studying the amazingmemories of chimpanzees, including Ayumu.He maintains that chimps simply have faster memory recall than people.How does Tetsuro Matsuzawa explain Ayumu’s performance in the game?
