Regularly spending time in a sauna (桑拿房) may help keep the heart healthy and extend life,say Finnish scientists in the journal JAMAInternalMedicine.
Researchers from the University of Eastern Finland (UEF) studied 2,300 middle-aged men
for an average of 20 years.They divided the men into three groups according to how often they used a sauna each week.Over the course of the study,49% of men who went to a sauna once a week died,compared with 38% of those who went two to three times a week and just 31% of those who went four to seven times a week.Frequent visits to a sauna were also linked with lower death rates from heart disease.
The results don’t surprise Dr.Thomas H.Lee,founding editor of the HarvardHeartLetter.“The beneficial effects of a sauna have been well documented in the past.It lowers blood pressure,and there is every reason to believe that its effects are good for your heart,”says Dr.Lee.
Sauna use is deeply rooted in Finnish culture.A nation of 5.5 million people,Finland has as many saunas as television sets—around 3.3 million.Most of the saunas are in people’s homes,although they’re also in offices and factories.
The very nature of the Finnish sauna is designed to reduce stress,the researchers say.The sauna has been a gathering place for family and friends for centuries.And a basic sauna rule,which discourages people from discussing controversial topics while bathing,is taught to the Finns during childhood.
The Finnish researchers suggest that saunas may provide similar benefits to exercise because the high temperatures can drive heart rates to levels often achieved by moderate-intensity (中等强度的) physical activities.
So can sitting in a sauna take the place of exercising?“I don’t know if I would take a sauna for exercise,” Dr.Lee says.“But exercising and then taking a sauna seems like a very healthy lifestyle.”
【语篇解读】本文是说明文。

A.It can be harmful to use a sauna too often.
B.Regular sauna users are likely to live longer.
C.Different people have different sauna habits.
D.Saunas may lower death rates from heart disease.

5.What does Dr.Lee think of UEF researchers’findings?
A.They are amazing.
B.They are interesting.
C.They match his expectations.
D.They go against past documents.

主题语境:人与自我语篇类型:说明文难度:★★★☆
Today different online exercise programs are challenging the concept of traditional fitness models.Gyms and health clubs are no longer limited to “the four walls”.Digital extensions of traditional fitness are appearing,and to reach as many people as possible,the fitness industry is expanding its boundaries through virtual (虚拟的) fitness and accepting the latest scientific findings and technological advancements in health technology.
Exergames(运动游戏) are a combination of physical exercise and digital games.Now fun and fitness are combined in various digital gaming products,products like Wii Fit Plus,Fitness Evolved,and Kinect Sports.What’s more,health technology is often built using principles of neuroscience,a science focused on studying the brain.Fitness Evolved,for example,focuses on stress and how you react to different stressors.This program helps you feel less threatened (受到威胁的) by targeting your specific stressors and then adjusts based on your interaction with the app.
Now there are a lot of smart exergames,one of which is BurnAlong.This online video platform combines the advantages of having a human instructor with the perks of practicing in the comfort of your own homer.The platform lets users connect with whoever makes them feel most motivated—be it their favorite gym instructors,or friends who might be living on the opposite side of the country.A wide variety of programs are offered through the platform,as well as different effort levels,so everyone can find something that suits their level of fitness.
Another example is Zwift,an online multiplayer video game based on indoor cycling.It allows you to join an online cycling group that includes members from over 150 countries.BitGym is also a smart virtual fitness app.As you train,you’re given beautiful virtual scenery to look at,complete with natural sounds and location-specific facts.For this app,all you need to do is place your smartphone or tablet on your sports machine.
【语篇解读】为了吸引尽可能多的人,健身行业正在通过虚拟健身扩展其边界,接受最新的科学发现和健康技术方面的技术进步。

A.To show how health technology is built.
B.To explain what exergames actually are.
C.To prove the popularity of digital products.

解析推理判断题。

2.What does the underlined word “perks” in Paragraph 3 probably mean?

B.Benefits.
C.Chances.

3.In which exergame are you exposed to virtual natural beauty?
A.Kinect Sports.
B.BurnAloog.
C.Zwift.
D.BitGym.
答案 D
解析细节理解题。

Ⅵ.概要写作
阅读下面短文,根据其内容写一篇60 词左右的内容概要。

Every morning,when my alarm goes off,I wake from my slumber and hit the snooze button.Then I crawl back under the quilt to grab a few more minutes of shut-eye.“Tonight I’ll go to bed early,” I tell myself.But,evening comes and I get a second wind,completely forgetting about my early night.Why am I finding it so difficult to get a good night’s sleep?And is it a problem?
The amount we sleep has declined over the years and insomnia(失眠) is on the rise.Modern technology is often blamed.The light from our smartphone affects levels of melatonin—the
sleep-inducing hormone—keeping us wide awake into the early hours.
Lack of sleep can badly affect our health and memory.We need deep sleep to move our memories from short-term storage into long-term storage.If we don’t get enough sleep,we could lose these memories.This is especially disastrous for people studying for exams.
So,how can we learn to sleep better?For Professor Till Roenneberg,it’s important for people to recognize they have an internal body clock.This determines whether you are a night owl,an early bird or somewhere in the middle.We don’t have any choice.“It’s like feet,” he said.“Some people are born with big feet and some with small feet,but most people are somewhere in the middle.” Our work schedules are out of sync with our natural sleep patterns.He says this leads to “social jetlag” where people feel like they are constantly in the wrong time zone.
Paul Kelley — a sleep expert from the University of Oxford—says that most people are getting up too early.He believes work and school should start a few hours later.Many companies are starting to realize more sleep can mean a more productive workforce and are changing work schedules.While in some countries,office workers are heading to relaxation parlors at lunchtime to take power naps in hammocks or massage chairs.This is much healthier than catching forty winks while sitting on the toilet or dropping off at their desks.
So,if like me you find yourself hitting your snooze button every morning — don’t feel bad.It’s just our body clocks!
参考范文
What problems may be caused by lack of sleep?How can we have a good sleep?(要点 1) People sleep less because of using too much electronic devices,which makes our short-term memory get worse.(要点 2)We have an internal body clock and if it doesn’t match our work schedule,we feel constantly tired,as if we were in the wrong time zone.(要点 3) Experts say we needn’t get up early,and many companies believe more sleep means a more effective workforce.(要点 4)

A shirt,tie and blazer may not be my favorite,but if I were given the choice,I wouldn’t throw away the idea of school uniform.Wearing a uniform is a badge of pride,creates an identity for a school and is an important part of being a school student.
My school is one of many that seem to be shifting to a more formal uniform—this September I will be wearing a shirt and blazer instead of my old jumper and polo shirt.A number of students have complained about the change,but some people believe that a school uniform can improve learning by reducing distraction,sharpening focus on schoolwork and making the classroom a more serious environment,allowing students to perform better academically.Perhaps most importantly,a uniform means students don’t have to worry about peer pressure when it comes to their clothes.When everyone is dressed the same,worrying about what you look like isn’t so important.There is no competition about being dressed in the latest trend,which would put a great deal of financial pressure on students and parents.Potential bullies have one less target for their insults;it’s hard to make fun of what someone is wearing when you’re dressed exactly the same.
In America,where a majority of schools do not have a uniform,roughly 160,000 children miss school every day due to fear of attack or intimidation by other students.This might not be directly linked to what they’re wearing,but having a uniform can be a safety net for many students who might otherwise suffer from bullying.A strict uniform gives the impression that rules are strict too,perhaps helping maintain a sense of order at school.
My uniform might not be what I would wear in my own time,but it gives me a sense of belonging,takes away the pressure of what to wear and stops the bullies.School uniform isn’t fashionable,but that’s exactly why I think it should be here to stay.
【语篇解读】本文是一篇议论文。

在学校“我”选择穿校服,因为校服是学校的标志,学生统一穿校服能使教室成为严肃的场所,让学生更加专注于学习;此外,穿校服还能减少校园欺凌事件的发生。

1.Why does the writer mention American children without uniforms in the passage?
A.To show pity for American kids.
B.To raise the government’s attention.
C.To prove the benefits of school uniform.
D.To inform readers of American kids’ uniforms.
答案 C
解析推理判断题。

根据第三段的内容可知,在美国,大多数学校没有统一的校服,每天大约有 16 万名儿童因为害怕受到其他学生的攻击或恐吓而缺课。

这可能与他们的穿着没有直接的联系, 但是对于许多可能遭受欺凌的学生来说,校服是一种保护,而且也帮助学校维持一种秩序感。

据此可推知,作者在此提及美国儿童没有穿统一的校服旨在说明校服的好处,故 C 项正确。

2.What is the writer’s attitude towards school uniforms?
A.Disapproving.
B.Confused.
C.Suspicious.
D.Favorable.
答案 D
解析观点态度题。

根据最后一段中的
“...itgivesmeasenseofbelonging,takesaw aythepressureofwhattowearandstopsthebullies.Schoolunifo rmisn’tfashionable,butthat’sexactlywhyIthinkitshouldbeheretostay.”可知,“我”的校服给了“我”。
