你需要锻炼身体的三个原因

 　　1. It helps with addiction 1 control

　　1.锻炼有助于控制癖嗜
　　The brain releases dopamine, which responds to any form of pleasure, be it sex, drugs, alcohol or food. Some people become addicted 2 to dopamine and substances that produce it—especially drugs or alcohol.
　　大脑会分泌多巴胺，多巴胺会对任何形式的压力做出反应，无论是性，毒品，酒精，还是食物。一些人逐渐对多巴胺以及产生多巴胺的物质上瘾——尤其是毒品或者酒精。
　　Regular exercise can help in this addiction recovery as it effectively distracts you, making you de-prioritize your cravings. When faced with mental or emotional challenges in life, exercise can help you cope in a healthy way instead of resorting to alcohol, drugs or other negative behaviors that ultimately only make your symptoms worse. Regular exercise can also help to boost your immune system.
　　定期运动有助于你戒掉这些成瘾行为，因为锻炼可以分散你的注意力，降低你对成瘾行为的渴望等级。当面对生活中的心理或者感情挑战的时候，运动可以帮会你用健康的方式应对，而不是诉求于酒精，毒品以及其他最终只会导致你症状更严重的一些其他消极的行为。定期锻炼也能帮助你增强免疫系统。
　　2. Your risk of diabetes 3 goes down
　　2.降低患糖尿病的风险
　　Within one week of your regular exercise, your sensitivity to insulin becomes greater and that, in turn, lowers your blood sugar levels, reducing your risk of Type 2 diabetes.
　　一周之内的定期锻炼之后，你对胰岛素的敏感度会变得更好，这反过来会降低你的血糖水平，降低患2型糖尿病的风险。
　　Also, exercise can decrease your stroke risk; given that two of the greatest risk factors for strokes are high blood pressure and heart disease, exercise with its benefits of a stronger heart and better circulation is crucial.
　　而且，锻炼会降低你的中风风险；鉴于导致中风的两个最大的因素就是高血压和心脏病，运动在增强心脏功能和促进循环方面的益处非常重要。
　　The U.S. Centers for Disease Control and Prevention recommends at least 30 minutes of moderate exercise at least five days a week for optimum health, though you should always check with your doctor if you have any health concerns before beginning any exercise program.
　　美国疾病防控中心建议，为了身体最佳的健康状态，每周至少5天都要适度运动至少30分钟，但是如果你有任何健康问题的话，在你开始任何运动项目之前，你应该要常常咨询你的医生。
　　3. You’re shedding belly 4 fat
　　3.减少腹部脂肪
　　When you do one month of regular exercise, your body ditches those excess fats and gains muscle. An Australian study shows that overweight people who took part in a four-week program of moderate exercise reduced abdominal 5 fat by 12 percent.
　　当你做一个月的定期运动之后，你的身体会清除那些多余的脂肪，让你身体的肌肉增多。一项澳大利亚的研究表明，超重的人参加四周的适度运动项目之后，腹部脂肪减少了12%。
　　1.respond to响应
　　So how do the different skill levels respond to a model like this?
　　那么不同的技能水平又如何回应到这样的模型上呢？
　　2.immune system[免疫] 免疫系统
　　The immune system then kicks in, and the body and the virus wage all-out war.
　　此后，免疫系统开始发挥作用，身体与病毒之间的战争由此全面爆发。
　　3.given that只要是，考虑到；假定，已知
　　Obviously, given that impossibility, we have to do the next best thing.
　　明显地，考虑到那是不可能的，我们必须做好下一个事情。
　　4.check with与…协商；与…相符合
　　If you have any history of fractures or a family history of osteoporosis, check with a physician before jumping.
　　如果你有骨折史，或者你的家人有骨质疏松史，那么在跳之前让内科医生检查下。
