每小题2.5分,满分25分) 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项,并在答题纸上将该项涂黑. A Crossing your legs is an extremely common habit. While you may find it comfortable to sit with one knee crossed over the other, it might be causing health problems that you are not aware of. A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure. The reason this happens is because the blood in your legs has to work against gravity to be pumped back to your heart, crossing one leg over the other increases resistance, making it even harder for the blood to circulate. You won'

t feel any immediate effects, but sitting for long periods of time will hurt you forever. Crossing your legs can also lead to neck and back pain. Ideally, it'

s best for our bodies to sit with our feet planted flat, hip width apart, on the floor, but it'

s not easy to maintain perfect posture all day at the office. When you sit with your legs crossed your hips are in a twisted position, which can cause one of your pelvic bones(骨盆) to rotate. Since your pelvic bone supports your neck and spine(脊椎), this can cause pressure on your lower and middle back and neck. You also might notice that when you sit with your legs crossed for long periods of time your feet and legs get painful or have the feeling of being asleep. This is because when one leg sits on top of the other it causes pressure on the veins(静脉) and nerves in your legs and feet. It can cause numbness and/or temporary paralysis in the legs, ankles, or feet. While the feeling of discomfort may only last a minute or two, repeatedly crossing your legs until they feel numb can cause permanent nerve damage. So next time you sit down, try to get yourself in the habit of sitting with both of your feet on the floor. Not only will it help your posture and stability, but it will also save your health in the long run. 1. Which of the following is not the consequence of crossing legs? A. Neck and back get hurt. B.
