Personalised Exercise
At the start of every year,many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class.But finally many of us just struggle to fit exercise into our lives,or start off well and then give up.Why do we have a good plan at the beginning but fail to achieve it in the end How can we deal with the problem 1.　　
It is important to determine your motivation first.Are you mainly interested in de-stressing or in getting fitter If your goal is relaxation,then ask yourself if you want to do something energetic.2.　　　 If you have a calmer style,you can do something quite different.You could choose solitary exercise,such as walking the dog or doing some gardening.3.　　　 There are quite a lot of them,such as walking and running groups,dance classes,etc.On your own,you could go horse riding or swimming,or just download fitness exercise programmes and do them at home.
4.　　　 If you have free time at the weekend,you could book some time with a personal trainer who can come to your house,or you could meet him at the gym.If your life is not regular,you could choose the next couple of minutes you have to try an exercise DVD,or put your running shoes on and run for any length of time.
As you see,everything counts when you are doing exercise.Whatever your lifestyle is,you will be able to have something that suits you.5.　　　 Just sit down with a cup of tea,read this article again,and think about your options.Then finish the tea,get up,get going,and don’t stop.
A.Good exercise is necessary for physical health.
B.The key could be to find the right type of exercise.
C.If it is fitness you are after,group activities will be suitable.
D.You’d better create a personalised plan to get you into shape.
E.In this case,a type of exercise based on boxing may be right for you.
F.In other words,you can always find personalised exercise by yourself.
G.For people who are extremely busy,it is easier to fit exercise into daily lives.

Ⅲ.阅读理解(共4题;每题2.5分,共10分)
Everyone has their own way to “recharge” their sense of well-being—something that makes them feel good physically,emotionally,and spiritually even if they aren’t consciously aware of it.Personally,I know that few things can improve my day as quickly as a walk around the block or even just getting up from my desk and doing some push-ups.A hike through the woods is ideal when I can make it happen.But that’s me.It’s not simply that I enjoy these activities but also that they make me feel better and clear my mind.
Mental health and physical health are closely connected.No kidding—what’s good for the body is often good for the mind.Knowing that what you can do physically has this effect for you will change your day and your life.
Physical activity has many mental health benefits.These have been published in a journal and include improved brain health and cognitive function—the ability to think,if you will,a reduced risk of tension and worry,improved sleep and overall quality of life.Although not a cure for all,increasing physical activity directly contributes to improved mental health and better overall health and well-being.
Learning how to manage stress and getting screened for depression are simply good prevention practices in daily life.Awareness is especially important at this time of year,when disruptions to healthy habits and choices can be more likely and more annoying.
Shorter days and colder temperatures have a way of breaking up the normal life—as do the holidays,with both their joys and their stresses.When the rich sunshine and clear skies of temperate(温和的) months give way to terrible weather,less daylight,and festive gatherings,it may happen unconsciously or seem natural to be less physically active.However,that tendency is just why it’s so important that we are ever more mindful of our physical and emotional health and how we can maintain both at this time of year.

Fast walkers may live longer than dawdlers (缓慢的人)—regardless of their weight,a study suggests.
Researchers at Leicester University analysed data on 474,919 people with an average age of 52 in the UK Biobank between 2006 and 2016.They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old,and men who kept up the pace had a life expectancy of 85.2 to 86.8.Slow walkers didn’t have much encouraging prospects(前景):Women had a life expectancy of 72.4,and men of 64.8 years old,if they were more leisurely in their movements.According to the paper,that ratio held true even if the fast walkers were severely overweight.It does not necessarily mean fast walkers will live longer.Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.
It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.
In 2011,The Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski,who found the same:Walking speed was a reliable predictor of life expectancy.
In 2013,the US researchers found walking pace was linked to lower heart disease risk and longer life expectancy.In 2018,a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.
And Tom Yates,the physical activity professor at Leicester who’s behind the latest study,
has been publishing findings on this connection for years.
In 2017,he analysed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease—concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.

Personalised Exercise
At the start of every year,many of us promise ourselves that a certain number of times a week we will go to the gym or attend an exercise class.But finally many of us just struggle to fit exercise into our lives,or start off well and then give up.Why do we have a good plan at the beginning but fail to achieve it in the end How can we deal with the problem 1.　　
It is important to determine your motivation first.Are you mainly interested in de-stressing or in getting fitter If your goal is relaxation,then ask yourself if you want to do something energetic.2.　　　 If you have a calmer style,you can do something quite different.You could choose solitary exercise,such as walking the dog or doing some gardening.3.　　　 There are quite a lot of them,such as walking and running groups,dance classes,etc.On your own,you could go horse riding or swimming,or just download fitness exercise programmes and do them at home.
4.　　　 If you have free time at the weekend,you could book some time with a personal trainer who can come to your house,or you could meet him at the gym.If your life is not regular,you could choose the next couple of minutes you have to try an exercise DVD,or put your running shoes on and run for any length of time.
As you see,everything counts when you are doing exercise.Whatever your lifestyle is,you will be able to have something that suits you.5.　　　 Just sit down with a cup of tea,read this article again,and think about your options.Then finish the tea,get up,get going,and don’t stop.
A.Good exercise is necessary for physical health.
B.The key could be to find the right type of exercise.
C.If it is fitness you are after,group activities will be suitable.
D.You’d better create a personalised plan to get you into shape.
E.In this case,a type of exercise based on boxing may be right for you.
F.In other words,you can always find personalised exercise by yourself.
G.For people who are extremely busy,it is easier to fit exercise into daily lives.

In the rushing modern society,it can be all too easy to skip a meal or two.You might even do it on purpose.A study suggests going without one of the standard three meals a day might have a serious downside.
24,000 people participated in the study.Around 30 percent of the participants often had fewer than three meals a day.According to the data,those who were younger,male,with less of an education and a lower family income,were more likely to skip meals.Meal-skipping was also more common among those who smoked more,drank more,ate less healthy food,had more snacks,and took in less energy overall.
Compared with participants eating three meals per day,the risk for participants eating one meal per day was 30% higher for all-cause death,and 83% higher for cardiovascular(心血管的) disease(CVD) death.Those who ate two meals a day had a 7% increased risk of all-cause death and a 10% increased risk of cardiovascular disease death.
The CVD death rate of the participants who skipped breakfast was 40% higher compared with those who did not.The all-cause death risk was 12% higher for skipping lunch and 16% higher for skipping dinner compared with those who did not.Skipping breakfast was connected with a greater risk of dying from CVD,while skipping lunch or dinner was connected with a greater risk of all-cause death,including a rise in CVD risk.
There was even a problem for those who ate all three meals but had them too close together.Eating two neighbouring meals within 4.5 hours of each other was also shown to be connected with increased all-cause death risk.While the study seems to make messages difficult that suggest intermittent fasting(间歇性禁食) could be good for you,the data stresses the importance of regular refueling stops for the body.

Fast walkers may live longer than dawdlers (缓慢的人)—regardless of their weight,a study suggests.
Researchers at Leicester University analysed data on 474,919 people with an average age of 52 in the UK Biobank between 2006 and 2016.They found women who walked briskly had a life expectancy of 86.7 to 87.8 years old,and men who kept up the pace had a life expectancy of 85.2 to 86.8.Slow walkers didn’t have much encouraging prospects(前景):Women had a life expectancy of 72.4,and men of 64.8 years old,if they were more leisurely in their movements.According to the paper,that ratio held true even if the fast walkers were severely overweight.It does not necessarily mean fast walkers will live longer.Experts say it suggests walking speed could be a simple way for doctors to judge their patients’ general health alongside other tests.
It is hardly the first study holding up walking speed as a powerful evidence that appears to improve and determine our health.
In 2011,The Journal of the American Medical Association (JAMA) published a study by Stephanie Studenski,who found the same:Walking speed was a reliable predictor of life expectancy.
In 2013,the US researchers found walking pace was linked to lower heart disease risk and longer life expectancy.In 2018,a study from the University of Sydney found picking up your walking pace to even an “average speed” could cut your risk of premature death by a fifth.
And Tom Yates,the physical activity professor at Leicester who’s behind the latest study,
has been publishing findings on this connection for years.
In 2017,he analysed the same UK Biobank data and found walking speed appeared to affect the risk of dying from heart disease—concluding that the slowest walkers were twice as likely to suffer a heart-related death compared to quick walkers.
