While you may find it fortable 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 for this is that the blood in your legs has to work against gravity 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. This causes your body to increase your blood pressure to push the blood back to the heart. You wont feel any immediate effects, but repeated, drawnout increases in blood pressure can cause longterm health issues. So, planning to sit for a long period of time? Dont keep your legs crossed. “Crossing your legs at the knee can also cause pressure on the major nerve in your leg that passes just below your knee and along the outside of your leg，” explains Richard Graves, a medical 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 disfort 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.【文章大意】本文是一篇说明文。文章介绍了人们将一条腿放在另一条腿上(跷二郎腿)的习惯，这种行为会导致一些健康问题。【难句分析】The reason for this is that the blood in your legs has to work against gravity 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.(第二段第二句)分析：本句是一个主从复合句。两个that引导的都是表语从句，“making it.to circulate”为现在分词短语作结果状语。译文：这是因为腿部的血液要回流到心脏，就要与重力对抗，并且把一条腿放在另一条腿上会加剧这种对抗，这使得血液循环更难了。1What can we learn about crossing ones legs?AIt is a very bad social habit，BIt can do harm to peoples health.CIt is usually practiced deliberately.DIt can make others feel unfortable.答案与解析：B考查细节理解。根据文章前三段内容可知，人们将一条腿放在另一条腿上(跷二郎腿)会使血压上升，给腿部和脚部的某些神经带来压力，引起健康问题。故选B项“它可能对人们的健康有害处”。2According to the study, sitting with your legs crossed can _.Aaffect your blood pressureBresist gravity effectivelyClead to heart attacks easilyDimprove the function of legs答案与解析：A考查细节理解。根据第二段第一句“A study published in Blood Pressure Monitoring stated that sitting with your legs crossed can increase your blood pressure.”可知，一项研究表明跷二郎腿会影响血压。故选A。3In the third paragraph “pins and needles” probably means _.Abeing highly flexibleBbeing a little tiredCserious muscle injuries Dslight sharp pains答案与解析：D考查词义猜测。根据上文可知，将一条腿放到另一条腿上所产生的这种压力会使得脚部、腿部某些肌肉无知觉、麻痹。故选D项“轻微的刺痛”。4What is the main purpose of the text?ATo pare mon habits.BTo evaluate the effects of an experiment.CTo give readers some advice.DTo introduce research methods.答案与解析：C考查写作意图。通读文章内容可知，文章介绍将一条腿放在另一条腿上所导致的健康问题，旨在建议读者不要跷二郎腿。故选C。B(xx合肥市高三调研性检测)The effects of coffee consumption on health have long been a subject of conflict and uncertainty. Since the 1980s, some have spoken out against coffee as its harmful to health, while others have weled coffee for its supposed benefits to health. According to a scientific report, mild coffee consumption, three to five cups per day, can be taken as a healthy dietary pattern, along with other healthful behavior. The report also says that coffee consumption helps reduce the risk of heart disease and it protects against Parkinsons disease.According to Dr. Donald Hensrud of Mayo Clinic, high consumption of coffee has health risks. Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body. Some studies said that drinking two or more cups of coffee daily can actually increase the risk of heart disease in these people. According to conclusions from a recent study led by Dr. Gregory Marcus, a doctor from the University of California, San Francisco, daily moderate consumption of caffeine, less than 4 cups, is not associated with these issues. Until the scientific munity reaches a general agreement on the effects of coffee consumption on human health, it will be up to the individual to decide whether the benefits of drinking coffee are greater than the risks.When informed of these possible health benefits and harm of drinking coffee, Harwood, a high school student stated, “Even though there might be some negative effects of drinking coffee, for the most part, coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”【文章大意】本文是一篇说明文，主要介绍了人们对咖啡是否有益于身体健康的几种不同观点。【难句分析】Dr. Hensrud mentions the dangers of high coffee consumption for people with a certain illness that slows the breakdown of caffeine in the body.分析：该句为主从复合句。句中that slows the breakdown of caffeine in the body为that引导的定语从句，修饰先行词a certain illness。译文：Hensrud博士提到了对于患有某种疾病的人，大量饮用咖啡会有危害，(因为)这种病会减缓体内咖啡因的分解。5What is the peoples attitude towards the effects of coffee on health according to Paragraph 1?ADisapproving. BTolerant.CDoubtful. DMixed.答案与解析：D考查细节理解。根据第一段第一句“The effects of coffee consumption on health have long been a subject of conflict and uncertainty.”可知，长期以来，饮用咖啡是否对健康有影响一直是有争议的、不确定的。D项意为“混合的，混杂的”，符合题意，故D项正确。6What does the underlined word “moderate” in Paragraph 4 probably mean?APersonal. BSlight.CReasonable. DHeavy.答案与解析：C考查词义猜测。根据该句中的“less than 4 cups”可知，饮用的咖啡不超过4杯；据此可以判断，该句是说，每天摄入适量的咖啡因对身体无害。据此可知，画线词意为“适度的”，故C项正确。7What can we infer about Harwood?AHell keep on drinking coffee.BHe loves his high school life.CHe often falls asleep in class.DHe has some health problems.答案与解析：A考查推理判断。根据文章最后两句“Even though there might be some negative effects of drinking coffee, for the most part，coffee drinking sounds good for health. Not to mention I need coffee to stay awake.”可知，Harwood认为，尽管喝咖啡可能会带来一些负面影响，但大多数情况下，喝咖啡对健康有好处；更不用说，他需要咖啡来保持清醒。据此可以推断，他将继续喝咖啡，故A项正确。8What would be the best title for the text?AWhy People Love Coffee?BHow Coffee Affects Health?CThe Culture of Coffee DrinkingDThe New Findings of Heart Disease答案与解析：B考查标题判断。通读全文内容可知，文章主要介绍了人们对咖啡是否有益于身体健康说法不一。有人认为适量饮用咖啡有益身体健康，有人却认为过量饮用咖啡会增加心脏病的发病率。据此可知，B项最适合作为本文的标题。.七选五(xx云南省昆明市高三复习教学质量检测)How to Make a Chinese Hot Pot Eating a Chinese hot pot is a very mon experience.
