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.

Thefailure 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 andwhy certain procedures go wrongA registry also helps surgeons learn quickly whetheraspecifictype of implant is particularly problematic,"Every country that has developedaregistry 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.2.Why does Sweden have a lower rate of hip implant failure?（）

3.There here have been great changes in the lives of womanDuring the twentieth century thewas an unusual shortening of the time of g woman's.lifespentin caring for children.A woman marrying at the end of the 19th century would probably have been in her middle twenties, andwould be likely to have seven or eight children.of whom four or five lived till they were five years old.By the time the youngest was fifteen.the mother would have been in her early fifties and would expect to live a further twenty years.(during whichcustom,chance and health made it unusual or her to get paid work.Today women marry younger and have fewer children.Usuallya woman's youngest child will be fifteen when she is forty-five and is likely to take paid work until retirement at sixty.Even while she has the care of children,her work is lightened by household appliances(家用电器）and convenience foods.This important change in women's way of life has only recently begun to have its full effect on women's economic position.Even a few years ago most girls left school at the first opportunity and most of them took a full-time job.However,when they married,they usually left,work at once and never returned to it..Today the school-leaving age is six-teen,many girls stay at school after that age, and though women tend to marry younger,more married women stay at work at least until shortly before their first child is born.Very many more afterwards,return to full or part-time work.Such changes have led to anew relationship in marriage,with both husband and wife accepting a greater share of the dutiesand satisfaction of family life,and with both husband and wife sharing more equally in providing the money and running the home,according to the abilities and interest of each them.According to the passage,it is now quite usual for women to（）

Passage Two

In the modern technological world the sea offers many resources to help mankind survive. (82)Resources on land are beginning to grow less. The sea, however, still offers hope to supply many of man’s needs.

The riches of the sea yet to be developed by man’s technology are impressive. Oil and gas explorations have existed for nearly thirty years. Valuable amounts of minerals such as iron, nickel and copper and so on exist on the ocean floor, ready to be mined.

Fish farming promises to be a good way to produce large quantities of food.The culture of fish and shellfish is an ancient skill practiced in the past mainly by Oriental peoples.

Besides oil and gas, the sea may offer new sources of energy. Experts believe that the warm temperature of the ocean can be used in a way similar to the steam in a steamship. Ocean currents and waves offer possible use as a source of energy such as hydroelectric power.

Technology is enabling man to explore ever deeper under the sea.The new undersea technology is providing divers with diving suits and undersea chambers that are kept at sea level pressure. The development of strong,new materials has made this possible. The technology to harvest the sea continues to improve. By the year 2000, experts believe that the problems to exploit the food, minerals, and energy sources of the sea will be largely solved.The word ―exploit ‖ in the last paragraph could best be replaced by________.

14.The dog has always been considered man’s best friend. Always noted for being particularly faithful in watching over children, he also has his place by the fireside, in the cow pasture, on the sheep range(放牧区), and beside the hunter in forest. He is easy to train, works hard, and often performs astonishing feats. And in the frozen polar regions he was once the principal motive power, before being lately displaced by the plane and helicopter.　　Because he howls or whines in the presence of impending death, the dog was once thought to have supernatural powers and believed to be capable of seeing gods and ghosts invisible to men. Actually, the basis for these beliefs lies in the hound’s sensibility to people’s feelings and his superior hearing ability and sense of smell, which enable him to detect signs hidden from human observation. His record of saving lives is outstanding, for he often gives warning of fire and other dangers not noticed by his master.　　The dog’s major contribution, however, has been to medical research. Both his diet and his structure are comparable to those of the human being, and so he has been the subject of countless demonstrations and experiments. Open heart surgery has been made possible largely because of the dog. But his sacrifice has repaid his own species as well by safeguarding it from rabies(狂犬病), distemper, and other diseases.
The article does not say whether the scientists’ experiments with dogs have .

15.根据以下资料，回答66-69题。We first think of the traditional or nuclear family．This is a two-generation family, the father and the mother and their own children．Most couples wanted to have four children, two boys, two girls. 　　Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations．This kind of family with grandparents, parents, and grandchildren is called an extended family．This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter．This is more possible now that American homes have become larger．What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits． 　　Now, the fatherless or motherless family is one kind of what we call a single-parent family．In the fatherless family it's just the mother and her children．As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce．There are also a growing number of motherless families--where the father raises the children, for any of the same reasons．A motherless family may also be fatherless, but still a family with one adult．This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work. 　　One other new kind of family is becoming increasingly more common．A single parent with one or more children will marry again．Perhaps the other parent is also a single parent．Together they will start what is called a blended family, which blends together or combines the children from two other families.67 How is a blended family formed?
