module 1 our body and healthy habits课时作业.阅读a(2020河南省八市重点高中联盟高三上期“领军考试”试题)millions of people are familiar with itsnoring (打鼾), the number one annoyance in the bedroom at night. about one in two men and one in four women of middle age or older snores in their sleep. previously dismissed as just an annoying disturbance of the peace, snoring is now recognized as a serious sleep and health disorder. these nightly problems in sleep can even be lifethreatening!when snoring, loud breathing noises occur in the upper airways during sleep, as loud as a passing truck. thats the sound many people fall asleep to. men over 50 years old, especially snore. as many as 60 to 80 percent in this age group are affected.now theres a revolutionary helper that immediately improves nasal (鼻的) breathing and can thereby prevent snoring. it is called the silentsnore, and its the first small and easytouse device for combating bothersome snoring noises. tens of thousands of people have already used this little wonder to sleep better and more peacefully at night. and indeed snoring can easily be combated with this method!the silentsnore gently widens the nostril (鼻孔) to reduce respiratory (呼吸系统) resistance in the nose. in other words, air can flow better into the lungs through the nose. as soon as the body registers that nasal breathing is working without restriction again, it unconsciously switches to (much healthier) nasal breathing. in contrast to things like chinstraps, silentsnore does not disturb you while you sleep.this ingenious little device controls snoring when sleeping without interfering the normal sleep cycle. a normal and healthy sleep cycle should include at least 25% at deep sleep, by relieving snoring effectively, stop disturbing your sleeping partner immediately, and guarantee your body rest and regenerate well. you can place your order online through the official website in china. your silentsnore will be delivered to your doorstep.篇章导读：本文是一篇应用文。人们认为打鼾只是一种吵人的噪音，但事实上它会危害健康，甚至危害生命！幸运的是，现在有办法可以治疗这种病了！1why should we try to prevent snoring?abecause loud breathing noises occur in the upper airways during sleep.bbecause its the number one annoyance in the bedroom at night and it can be life threatening.cbecause as many as 60 to 80 percent in this age group are affected by snoring.dbecause snoring was recognized as a serious sleep and health disorder.答案：b细节理解题。根据文章第一段最后两句话可知，打鼾不只会产生让人烦恼的噪音，甚至会让人有生命危险。2if there are 24 girls in your class, how many of them will probably snore when sleeping?a12. b6. c8. dwe dont know.答案：d细节理解题。文章第一段提到了中年以上的男人和女人打鼾的比例，第二段提到了50岁以上的男人打鼾的比例，没有提及高中阶段的女孩子。3silentsnore has the following advantages except .apromoting better breathing breducing and stopping snoringcinterfering the normal sleep cycle dbeing small and easy to use答案：c细节理解题。根据文章最后一段第一句可知，silentsnore这种装置在睡觉时可以控制打鼾但是不会干扰正常睡眠周期。【词汇积累】be familiar with 对熟悉thereby adv. 因此；由此；从而bothersome adj. 引起麻烦的；困扰人的unconsciously adv. 不知不觉；无意识地【难句分析】原文：when snoring, loud breathing noises occur in the upper airways during sleep, as loud as a passing truck.睡觉打鼾时，上呼吸道会发出很大的呼吸声，就像路过的卡车发出的声音一样大。(第二段第一句)分析：本句为主从复合句。when引导时间状语从句，从句使用了省略句式，因为主句和从句的逻辑主语一致，相当于when (you are) snoring, loud breathing noises (of you) occur .。此种用法主要用来描述或说明某种情况或现象，是“对事不对人”。b(2020陕西省百校联盟top20联考)scientists from around the world examined whether supplements marketed are good for brain health, particularly in those aged over 50. despite the claims of some supplements that they could improve cognitive (认知的) skills, no clear evidence was found to back this up.the report said, “for the handful that have been researched, several welldesigned studies of supplements for brain health found no benefit in people with normal nutrient levels. its unclear whether people who lack nutrition can benefit their brains by taking a supplement. the pills failed to protect against dementia (痴呆) and did not slow the process or improve the symptoms of the disease and the report said that a healthy diet rich in fruit and vegetables, being physically active and getting sufficient sleep were linked to better brain function.”the value of the food supplement market in britain is expected to reach more than 1 billion by 2012 and supplements sold on the high street for brain performance cost up to 26 for 60 pills. and caroline abrahams, the charity director at age uk said that people were better off spending money to improve diets.the report did find evidence suggesting that supplements could benefit people diagnosed with lacking vitamin. it added that these should only be taken if advised by a doctor because some supplements could interact with medicines or contain high levels of nutrients, which could be deadly. supplements were not strictly controlled in the way that medicines were and may not contain highquality ingredients or what was on the label, the report said.the health food manufacturers association, which represents the british supplement industry, said that the report was based on the american market. in britain products could only make claims approved by the european food safety authority, such as the zinc (锌) contributed to normal cognitive functions, a spokesman said.篇章导读：本文是一篇说明文。文章讲述了科学家们发现补充剂并不能增强大脑健康和对抗痴呆症，同时给出了相应的建议。4what is the finding of the scientists about the supplements?athey bring about no positive effect.bthey break the balance of normal life.cthey get people to get addicted to them. dthey are hardly suitable for the younger.答案：a细节理解题。根据第一段中的“no clear evidence was found to back this up”和第二段中的“found no benefit in people with normal nutrient levels . the pills failed to protect against dementia (痴呆) and did not slow .”可知补充剂没有什么积极的效果，故选a项。5the author uses the third paragraph to show people should .abe aware of their needs clearlybchange their daily diets regularlyctake control of the market strictlydmake use of their money properly答案：d推理判断题。根据这一段中列出的英国食品补充剂市场的高价值、补充剂高价格以及最后引用caroline abrahams的话“better off spending money to improve diets”可知，作者借此说明要合理使用金钱，故选d项。6what should people do if they do need to take supplements?afollow professional suggestions.bbe sure of the vitamins they lack.crefer to the instructions

good for us, but can you get the benefits without actually doing the exercise？” asks michael mosley.having a hot bath or a sauna is a good way to soothe your arms and legs after exercise, but what happens if you do it instead of exercise? dr steve faulkner of loughborough university asked me to take part in an experiment comparing the relative benefits of having a long, hot bath versus an hour of hard cycling.for this study i join a group of volunteers who have all been fitted with monitors which continuously record blood sugar levels. keeping your blood sugar level within the normal range is an important measure of your “metabolic” fitness.the first part of the experiment is very relaxing, consisting of having a long, hot bath. while i sit in the bath, which they keep at 40 ， steve closely monitors my core temperature. once it has risen and stayed there, i am allowed out.a couple of hours after my bath i have a light meal. since we want to see how having a hot bath compares with exercise we repeat the experiment.so whats the result?“one of the first things that we were looking at，” steve says, “is the energy expenditure (消耗) while youre in the hot bath and what we found was an 80% increase in energy expenditure just as a result of sitting in the bath for the course of an hour.”this is nothing like as many calories as cycling for an hour (which comes out at an average of 630 calories), but we do burn 140 calories, the equivalent of a brisk 30minute walk.篇章导读：本文是一篇说明文。实验发现，一个小时的热水浴虽然没有骑一个小时自行车所消耗的热量多，但其所消耗的热量相当于半个小时的快步走所消耗的热量。8what is the meaning of the underlined word

bath and cycling.bto tell people how to lose weight.cto show the benefit of hot bath.dto encourage people to have a hot bath instead of cycling.答案：a推理判断题。根据第二段第二句“dr steve faulkner of loughborough
