Crossing your legs is an extremely common habit; most people don’t even notice that they’redoing it when they sit down. 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 canincrease your blood pressure. The reason for this is that the blood in your legs has to work againstgravity to be pumped back to your heart and that crossing one leg over the other increases resistance, making it even harder for the blood to circulate (循环). This causes your body toincrease your blood pressure to push the blood back to the heart. You won’t feel any immediateeffects, but repeated, drawn-out increases in blood pressure can cause long-term health issues. So,do you plan to sit for a long period of time? Don’t keep your legs crossed.

“Crossing your legs at the knee can also cause pressure on the major nerve in your leg thatpasses just below your knee and along the outside of your leg,” explains Richard Graves, amedical expert. This pressure can cause numbness and temporary paralysis (麻痹) of some of the muscles in your foot and leg, preventing you from being able to raise your ankle—what we know as that “pins and needles” sensation. 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 onthe floor. Not only will it help your posture and stability, but it will also save your health in thelong run.

1、According to the first paragraph, what can we learn about crossing one’s legs?

A. This is a rare habit in life.

B. People do this unconsciously when they sit down.

C. It’s very uncomfortable to sit like this.

D. Most people are aware of the health problems it can bring.

【参考答案】B

【解析】事实细节题。根据第一段可知，跷二郎腿是人们一个非常普遍的习惯，大多数人坐下来的时候甚至都没有注意到自己在做什么。虽然你可能会觉得这样坐着很舒服，但这可能会导致你没有意识到的健康问题。由此可知，人们总是无意识地跷二郎腿，这并非是生活中少见的习惯，而且这样坐很舒服，也很难有人意识到跷二郎腿导致的健康问题。故选B。

A. Crossing your legs won’t have any effect.

B. Crossing your legs can cause poor circulation.

C. Crossing your legs can lower your blood pressure.

D. Crossing your legs for long periods of time doesn’t cause health problems.

【参考答案】B

【解析】事实细节题。根据第二段可知，发表在《血压监测》上的一项研究表明，双腿交叉坐着会增加血压。原因是腿部的血液必须克服重力才能被输送到心脏，而将一条腿交叉在另一条腿上会增加阻力，使血液更难循环。这会导致你的身体升高血压，将血液推回心脏。虽然你不会立即感受到任何影响，但血压反复持续升高会导致长期健康问题。由此可知，跷二郎腿会导致血液循环不良。故选B。

A. Being a strong nervous.

B. Being highly flexible.

C. Serious muscle injuries.

D. Slight sharp pains.

【参考答案】D

【解析】推理判断题。根据第三段第二句可知，这种压力会导致你的脚和腿上的一些肌肉麻木和暂时瘫痪，让你很难抬起脚踝——就像我们知道的“针扎”的感觉。由此可以推断出，“pins and needles”是对前面症状的总结词，应该与“肌肉麻木和暂时瘫痪，难以抬起脚踝”的意思相近，是轻微的、时效短的、并不严重的刺痛感和麻痹感。故选D。

A. In a newspaper.

B. In a science fiction.

C. In a health magazine.

D. In a travel guide.

【参考答案】C

【解析】主旨大意题。文章以生活中非常普遍的习惯——跷二郎腿为话题展开，并指出跷二郎腿虽然很舒服，但却会给人的身体带来健康问题。同时，又引用发表在《血压监测》上的一项研究表明，以及医学专家Richard Graves的话来论证这个观点，即跷二郎腿会对人体的血压和腿部神经带来长期的压力。通读全文可知，本文是一篇具有科普性质的健康文章，目的是为了让读者意识到跷二郎腿的危害，养成一个良好的坐姿习惯。故选C。

【翻译】

跷二郎腿是个极其普遍的习惯；大多数人坐下时甚至都没察觉到自己正在这么做。虽然把一条腿的膝盖搭在另一条腿上坐着会让你觉得舒服，但这可能会引发一些你并未察觉的健康问题。

发表在《血压监测》上的一项研究表明，跷二郎腿坐着会使血压升高。究其原因，腿部血液需要克服重力才能回流至心脏，而双腿交叠会增大阻力，让血液循环变得更加困难。于是身体就会升高血压，推动血液回流心脏。你不会立刻感受到任何不适，但血压反复、长期升高会诱发各类长期健康问题。所以，如果你需要久坐，就不要跷二郎腿。

医学专家理查德・格雷夫斯解释道：“膝盖处跷二郎腿还会压迫腿部的主要神经，这条神经就从膝盖下方、腿的外侧延伸而过。” 这种压迫会造成足部和腿部部分肌肉麻木、短暂麻痹，致使脚踝无法上抬，也就是我们常说的 “手脚发麻、针扎般刺痛” 的感觉。这种不适感或许只会持续一两分钟，但反复跷二郎腿直到腿部发麻，可能会造成永久性神经损伤。

因此下次坐下时，试着养成双脚平放地面的坐姿习惯。这不仅能改善体态、提升身体稳定性，从长远来看，还能守护你的身体健康。
