1 . When it comes to making healthy lifestyle changes, which should come first—changing your diet or becoming more physically active?
Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends (趋向)to be discouraging. That has led to the popularity of advising people to make changes gradually, and set smaller goals.
So the scientists divided 200 inactive participants who were 45 or older into four groups. One group was instructed in making diet and fitness changes at the same time; the second group was taught about diet changes first, and then fitness changes four months later; the third group changed their exercise habits first and made changes in their eating habits four months later; and the final, control group was not instructed in either diet or fitness changes but in how to manage their stress.
The researchers followed the groups for a full year. Compared to the control group, the three intervention (干预) groups made healthy changes in their diet. Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months. However, at the end of the year, the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels, while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year. The researchers suspect that changes to diet are easier to make than changes to physical activity.
The findings show, however, that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives. If folks change diet and exercise orderly, the scientists say, they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

2 . A gym membership can be nice.
Spend 5 to 10 minutes warming up before every workout. Not sure what to do? Try jumping jacks, leg or arm circles, or even dancing. Just get your blood pumping. Do a progressive aerobic (有氧的) activity that uses the same muscles you want to work out.
Do strength training twice a week to build muscles. Strength training, also called resistance training, makes you stronger and builds endurance (忍耐力).
Set achievable goals that you can break into smaller tasks. It’s one thing to say you want to get fit, but that means something different for everyone.
| A．After all, we work out to build our muscles. |
| B．Equipment is the key to carrying out a workout plan. |
| C．But you don’t have to have one to get into great shape. |
| D．For instance, slowly jog if you are going for a longer run. |
| E．Spend five to ten minutes cooling down after each workout. |
| F．Figure out what you plan to achieve and make that your goal. |
| G．Try to do exercises that work many parts of your body and make you feel stronger. |
3 . Common Mistakes New Runners Make
Running is a great way to get in shape and just about everyone can do it. However, many make a number of common mistakes, which can interfere (妨碍) with training or lead to injury.
·Doing too much too soon
One of the biggest mistakes new runners make is doing too much too soon. Slowly easing into a training program will help reduce the risk of injury, so you can continue on with your new running routine
·
Beginners might think they need to run every day (or nearly every day) to meet their fitness or weight-loss goals, but this couldn’t be further from the truth. Running is a high-impact activity which can be really hard on your body. So it’s important to give your body a rest between workouts.
·Not wearing the right equipment
•Running through pain
| A．Not taking rest days |
| B．If you’re just starting out |
| C．Comparing yourself to others |
| D．Running can be uncomfortable at times |
| E．It’s important not to use the same muscles |
| F．While it may be true that you don’t need expensive equipment to take up running |
| G．Experts suggest increasing your running distance by no more than 10% each week |
4 . How exercising changed their life
Name: Katelyn Block, 19 The problem: At the end of her junior year of high school, she fell into a serious eating disorder. The change: She was an athlete, but while she was sick, she stopped running. Later, she decided to get back into running. She made the decision to build her body back from the ground up. With a few months of hard work and determination, she graduated from high school with a healthy body. | Name: Amalia Biro, 24 The problem: Amalia was a horseback rider with her sight set on the Olympics, until one day she was thrown off a horse, leaving her left knee badly injured.

5 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometre race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University.
Like running, race walking is physically demanding, she says. According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories (卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

6 . For people suffering from depression, there’s an all-natural treatment they should use — getting more exercise. It could help fight depression, even if people have a genetic risk, new research shows.
For the study, researchers collected information from nearly 8,000 people and found those with related genes were more likely to have depression over the next two years after examining them. But that was less likely for people who were more active at the study’s start, even if they had a family history of depression. Higher levels of physical activity helped protect even those with the highest genetic risk of depression.
Both high-intensity (高强度) exercise and low-intensity activities were associated with a reduced risk of depression. Adding four hours of exercise a week could lower the risk of a new episode (一段经历) of depression by 17%, according to the study. “Our findings strongly suggest that, when it comes to depression, being physically active has the potential to remove the added risk of future episodes in individuals who are genetically risky,” said lead author Karmel Choi. “On average, about 35 additional minutes of physical activity each day may help people to reduce their risk and protect against future depression episodes.”
Depression is a common mental illness globally, with more than 264 million people affected. “Depression is so ubiquitous, and that underlines the need for effective approaches that can impact as many people as possible,” Choi said. And mental health and primary care providers can use the findings to advise patients that there’s something meaningful they can do to lower their risk of depression.

7 . A running chub is a community group made up of members that are interested in running. Some running clubs may focus on different types of running activities and require a certain level of expertise(专长) on the runner’s part.
Often,running clubs include training with a coach in the cost. However, if they don’t offer to coach members and provide only a group environment, the clubs may provide a discount on personal trainers. Keep in mind that the size of the club affects the discounts and services the club can provide.
Many running clubs are open to members of all ability levels.
Most running clubs have a website that often includes a mission statement(任务说明) for the club.
| A．A running club comes with a ton of benefits. |
| B．However, smaller running clubs often charge monthly. |

8 . Walking in the city is very different from walking in the park. A small psychology study suggests urban(城市的) environments can slow your step and possibly increase your mental load. A walk through nature, on the other hand, appears to ease your mind and quicken your pace. The findings show that natural settings may potentially reduce cognitive (认知的)tiredness and improve reaction times straight away. The study, which includes two experiments with two different approaches, was conducted among 65 university students in the lab.
The first of the two experiments in the new study focused on people’s way of walking and cognitive load. During this trial, participants were fitted with sensors and a dozen motion control cameras were set up to watch them repeatedly walk down a 15-metre room at their natural speed. The wall opposite them showed an image of either a nature scene or a city scene. After each walk, participants were asked to rate their feelings of discomfort in the visual environment. On the whole, when walking in city settings, people reported more discomfort and they walked at a slower pace, indicating a higher cognitive load.
The second experiment dug into some of the higher-level cognitive processes that might be at play. In the trial, participants were asked to distinguish between basic visual shapes on the computer while also in the presence of a natural or urban image(the same ones from the first experiment). Measuring reaction times in both natural and urban settings, the team found results to support their idea. In urban environments, participants were slower in distinguishing between simple shapes. The authors think this is because urban environments are more distracting(令人分心的) for our brains and take longer to process, but more research is needed to prove that idea.
1. How were the experiments conducted mainly?| A．By comparing. | B．By giving data. |
| C．By giving examples. | D．By explaining facts. |
| A．It can make us feel relaxed and react quickly. | B．It can activate our thinking and speed up our step. |

| C．They couldn’t concentrate properly. | D．They felt uncomfortable after walking. |
| A．Urban environment makes us more concentrated. | B．People’s feelings are decided by their pace of walking. |
| C．The result of the experiments is widely appreciated. | D．People tend to get tired more easily walking in the city. |
9 . Home workout
As long as there is a space at home, we can move. It will take time if we go outside as time is precious, especially in this fast- paced age. So many people like to exercise at home. However, without trainers, getting good exercises at home can be difficult.
Avoid over-training. Nowadays, a lot of people prefer to do some popular programs they see on social media. But a lot of these programs are high-in-tensity (高强度的) and designed to make you feel tired.
Do yoga in a suitable way.
| A．It can be tricky to do yoga at home. |
| B．Yoga is the most effective in the presence of an instructor. |
| C．Here is something you should pay attention to when you choose to exercise at home. |
| D．Instead, you should try a program that is working toward a goal, with exercises you’re able to do. |
| E．Watch your form. |
| F．But having bad form can lead to injury. |
| G．People find it easy to do these programs. |
10 . Running is often tiring and a lot of hard work, but nothing beats the feeling you get after finishing a long workout around the track.
But while it’s long been believed that endorphins (内啡肽) —chemicals in the body that cause happiness—are behind the so-called “runner’s high”, a study suggested that there may be more to this phenomenon than we previously knew.
According to a recent study published by a group of scientists from several German universities, a group of chemicals called endocannabinoids (内源性大麻素) may actually be responsible for this familiar great feeling.
To test this theory, the scientists turned to mice. Both mice and humans release high levels of endorphins and endocannabinoids after exercise. After exercising on running wheels, the mice seemed happy and relaxed and displayed no signs of anxiety. But after being given a drug to block their endorphins, the mice’s behavior didn’t seem to change. However, when their endocannabinoids were blocked with a different drug, their runners’ high symptoms seemed to fade.
“The long-held notion of endorphins being responsible for the runner’s high is false. Endorphins are effective pain relievers, but only when it comes to the pain in your body and muscles you feel after working out,” Patrick Lucas Austin wrote on science blog Lifchacker.
Similar studies are yet to be carried out on humans, but it’s already known that exercise is a highly effective way to get rid of stress or anxiety. The UK’s National Health Service even prescribes (开药 方) exercise to patients who are suffering from depression. “Being depressed can leave you feeling low in energy, which might put you off being more active. Regular exercise can improve your mood if you have depression, and its especially useful for people with mild to moderate (中等的) depression,” it wrote on its website.
It seems like nothing can beat that feeling we get after a good workout, even if we don’t fully understand where it comes from. At least if we’re feeling down, we know that all we have to do is to put on our running shoes.
