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.3.The U.S.is trying to reduce joint replacement failure rate by（）

In china, it is relatively usual to ask people their age, but in the west, this question is generally regarded as impolite. This is particularly true 61 women, and even more 62 if the inquirer is a man. However, it is 63 to ask children their age, and some adults may not mind 64 either. In fact, some elderly people are quite happy to 65 their age, especially if they feel they look young 66 their age. Nevertheless, it is not very wise to ask a(n) 67 question like ―How old are you?‖if elderly people want to talk about their age, and perhaps receive a compliment on how young they look, they may easily 68 the topic themselves, and ask the other person to 69

how old they are. 70 such a situation, it is quite acceptable to discuss age 71.They normally expect to be complimented on their youthfulness, though rather than 72 that they look very old! 73 westerners do not usually ask people directly how old they are, this does not 74 that they are not interested to know how old other people

are. They may ask 75 for the information, 76 they may try to 77 the topic indirectly. Sometimes discussions about educational 78 and the number of years of working experience may provide some 79 , but this is not always the 80 .79.

8.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.[单选题] What is true to the fact in America?

13.Passage Three　　When you stretch out in the sun you can do one of the three things: you can use no sun tan oil, an ordinary sun tan oil; or Bergasol.　　If you don't use any sun tan oil when you're in the sun, you will burn surprisingly quickly. If you use an ordinary sun tan oil, you will protect your skin to a lesser or greater degree.How much protection depends on the "protection-factor number" on the bottle. Some oils block out so many of the sun's rays and you can stay in the sun all day without burning but you won't go very brown,either.　　Bergasol will protect your skin like an ordinary sun tan oil. It also has a tan accelerator that speeds up the rate at which the sun activates the skin cells that produce melanin(黑色素). It is melanin that gives the skin its brown colour. Bergasol enables you to go brown faster,am as the days pass the difference will become more obvious. Unfortunately, this special formulation isn't Cheap to prepare.So Bergasol is rather more expensive than ordinary sun tan oil. However, the price looks more attractive as you do.　　Bergasol It makes you go brown faster　　Protection Many people imagine that "cover-up" means you don't get a tan. Nothing to show for your holiday. Not so. With "cover-up", you can get brown if you want to. The point of "cover-up" is to protect your skin from the harmful rays of the sun which, according to the experts ,make your skin look older.　　That's what Solex Cover-up is all about--protection for your skin. It has a Sun Protection Factor 8, which makes it suitable for anyone. Find out how it works for you by consulting the Solex Sun Chart. On sale wherever Solex is.
