Healthy knees aren’t the main consideration in choosing high heels,but new research says chunky heels are just as bad for the knees as spindly stilettos（细高跟鞋）.“It takes a long time to feel the effects of knee osteoarthritis（骨关节炎）—and once you do it,it is too late,”said Dr.Casey Kerrigan,leading researcher of the study and associate professor at Harvard Medical School’s department of physical medicine.“I compare it to smoking—one cigarette is not painful,but over a lifetime it is.Wide-heeled shoes feel comfortable,so women wear them all day long,”Kerrigan said.“They are better for your feet than stiletto heels,but just as bad for your knees.”
In the study,researchers had twenty women wear two pairs of shoes with three-inch heels,one with a narrow heel and the other with a thick one.The scientists compared how much pressure was put on the women’s knees by both types of shoes.The women also walked bare-foot to test normal pressure.The scientists found that both types of shoes applied equal amounts of pressure to the knees.Compared with walking barefoot,the heels increased pressure on the inside of the knee by 26 percent.Increased pressure on the knee eventually leads to arthritis,experts say.
The idea that high heels are bad for your health isn’t new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes,tendonitis,knee pain,sprained(扭伤)ankles and back problems.But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis,a painful joint disease that destroys cartilage(软骨)surrounding the knee.The first study looked only at stiletto heels,and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.“This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health,”said Dr.Glem Pfeffer,a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.
【小题1】We learn from the passage that women choose chunky heels because .A．they want to walk comfortablyB．chunky heeled shoes are cheaper than stiletto heeled pairsC．chunky heels do less harm to kneesD．chunky heels are not painful at all【小题2】The study mentioned in the second paragraph found that .A．pressure on the foot is caused by high heelsB．the pressure is abnormal while walking barefootC．arthritis is always caused by pressure on the kneesD．both types of shoes have the same harm to the knees【小题3】It can be inferred from the passage that .A．people got to know the high heels are bad for health recentlyB．people have known the high heels are bad for health for yearsC．people haven’t known the high heels are bad for health yetD．people will be warned that the high heels are bad for health soon【小题4】Kerrigan’s late study looked at the chunky high-heeled shoes because .A．they feel more comfortableB．they are related to knee osteoarthritisC．they are worn by many womenD．they are different from stiletto heels【小题5】The best title for the passage may be .A．Talking Healthy Knees into ConsiderationB．High-heels Do Harm to KneesC．Chunky Heels and Stiletto HeelsD．When Wearing High-heelsA

(答案→)A 解析：【小题1】：细节理解题。根据第一段中的“Wideheeled shoes feel comfortable,so women wear them all day long”可知妇女选择粗高跟鞋是因为粗高跟鞋穿着舒服，A项与此意思相符。【小题2】推理判断题。从第二段中的“The scientists found that both types of shoes applied equal amounts of pressure to the knees.”可知，两种高跟鞋给膝关节带来的压力是等量的，所以它们对膝关节的伤害是一样的。【小题3】细节理解题。根据第三段开头“The idea that high heels are bad for your health isn’t new—scientists have warned women for years that...”可知B项与此一致。【小题4】细节理解题。根据第三段中的“The first study looked only at stiletto heels,and Kerrigan said she wanted to study the chunky highheeled shoes she noticed many women wearing.”可见，起初的研究对象只是细高跟鞋，Kerrigan后来对粗高跟鞋进行调查研究是因为她注意到许多妇女穿着粗高跟鞋。【小题5】主旨大意题。本文主要论述了鞋跟粗厚的高跟鞋和鞋跟细高的高跟鞋一样，都对膝关节有损害。所以B选项“高跟鞋伤害膝关节”是最佳选项。
