健康問題一直是生活中的熱點(diǎn)話題。尤其對(duì)于女性來說，你知道穿矮高跟鞋和純粹的高跟鞋對(duì)你身體健康的影響嗎？

Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos（細(xì)高跟鞋）.

"It takes a long time to feel the effects of knee osteoarthritis（骨關(guān)節(jié)炎）— and once you do, 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 had for your knees.”

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（扭傷）ankles and back problems.

But in 1998, Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage（軟骨）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（直覺地）know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopedic Surgeons who was not connected to the study.

1. What’s the main idea of the passage?

                                                                           

2. Which sentence in the passage is the closest in meaning to the following one?

In my opinion, it is similar to smoking, for smoking one cigarette does little harm but if you smoke all your life, it’ll be very painful.

                                                                          

3. Please fill in the blank in the passage with proper words or phrases to complete the sentence.（within ten words）

                                                                          

4. What do you think of wearing the chunky heels according to the passage? （within 30 words）

                                                                           

5. Translate the underlined sentence into Chinese.

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（細(xì)高跟鞋）.“It takes a long time to feel the effects of knee osteoarthritis（骨關(guān)節(jié)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.
