1 . If you're out for a run, what difference does it make if you're able to tough it out for another 50 seconds? If you're less than a minute from the top of the hill, that extra time can make the difference between having reached your goal and snatching defeat from the jaws of victory.

How do you get those extra seconds of energy? A research team at the Texes Tech University developed a study to measure what effect listening to music would have on exercise tolerance. The researchers based the study on a stress testing. As part of the testing, they noted any changes in heart rate and blood pressure as participants underwent physically stressful exercise.

The tests were done on treadmills (跑步机), which increased in both speed and incline (坡度) through three stages. In the final stage, the treadmills moved at 10 miles per hour at a 14-percent grade. Most of these tests were designed to last up to 40 minutes. The average gym-goers lasted 30 minutes. For this study, they divided 127 participants into two groups. One listened to upbeat(快节奏) music, while the other group had earbuds in but did not listen to music.

The group that listened to music was able to outlast the non-music group by an average of 50.6 seconds. Again, being able to go an extra minute may seem like a no-brainer ,but “after 30 minutes, you feel like you are running up a mountain, so even being able to go 50 seconds longer means a lot," said the study's lead author, Waseem Shami, MD.

The study has confirmed something runners and gym-goers have suspected for years: Listening to music during workout can be beneficial to your endurance. "Our findings reinforce the idea that upbeat music can help you exercise longer and stick with a daily exercise routine," said Shami. When doctors are recommending exercise, they might suggest listening to music, too."

2 . To get in shape soon, some people use “quick” methods without realizing that these methods can put their overall health in danger. For example, they lose weight by eating fat-free food. It’s true that consuming（消耗）fewer fats can help you get in shape sooner, but low fat foods like dried fruits, nuts, beans, etc, actually contain high amounts of calories. For example, fruit juice contains no fat, but has high calories, so drinking more than one glass of fruit juice won’t help in losing weight.

To rely only on fruit and vegetable juice to lose weight is also a wrong method. By replacing your meal with only juice, you decrease the calorie intake（卡路里摄取量）greatly. It’ll help lose weight, but it can make you lack energy, leading to headaches, stomach disorders, etc.

It’s true that exercise helps to keep healthy weight, but it’ll probably not help you much if you don’t take care of your diet by reducing your calorie intake. If you believe you can exercise every day and eat as much as you want, you’re incorrect. For healthy weight loss, you need to burn more calories than you consume. So, you need to limit the intake of food.

Wrong weight loss methods are dangerous. So if in doubt, you’d better ask a doctor before starting weight loss. Luckily, it’s possible to lose weight with healthy methods. For example, follow healthy food habits, exercise regularly for 20-30 minutes every day, and go on with a healthy lifestyle even after you lose weight. Anyway, as you don’t gain weight overnight, it can’t be lost in a short time either. Give yourself some time. Although healthy methods may take a bit longer to work, they’re surely good for your body.

3. How can we get more calories burnt than we consume according to Paragraph 3?

A．By reducing mental pressure.	B．By only drinking fruit juice.
C．By having more rest.	D．By exercising with food control.

4. What can be inferred from the last paragraph?

A．We should be patient with losing weight.

B．We can actually lose weight very easily.

C．Regular exercise is enough for us to lose weight.

D．We don’t have to consider our doctor’s advice.

3 . As is known, exercise helps to keep us in good health. Doctors at the American Heart Association suggest getting at least 150 minutes of moderate physical activity every week. Many people have an exercise routine.     1    . So, getting those 150 minutes is easier. But what about those times when you are sick? If you do not feel well, should you keep following your exercise routine? Will physical activity help you to feel better more quickly or will it delay the healing process?

Health experts answer these and other questions on the Mayo Clinic website. Mild to moderate physical activity is usually OK if you have a common cold. According to the experts, it is usually fine to exercise if your symptoms are all “above the neck”.     2    . In fact, exercise may make you feel better by “opening your blocked nose”. This may temporarily reduce congestion and help you to breathe more easily.

    3    , though. So be on guard for symptoms such as chest congestion, extreme cough or pain in the stomach. Besides, there are other symptoms that can tell you to avoid exercise. They include: a higher than normal body temperature, a sense of feeling extremely tired, also known as fatigue, and widespread muscle pain.     4    .

Finally, experts suggest learning to listen to your body. If you feel really bad, take a break and let your body rest. If you don’t feel too bad, these experts both suggest cutting back on the intensity (强度) of your exercise routine.    5    . Experts all indicate that a few days off from exercise when you are sick shouldn’t affect your performance. You can return to your usual intensity when you feel better.

A．These signs may include a runny nose, nasal congestion (鼻塞), sneezing or a minor sore throat

B．Experts especially point that if you feel tightness in the chest, it is not advisable to work out

C．They exercise for a few minutes every day or every other day

D．Exercising will result in more severe illness

E．For example, if you usually run, take a quick walk instead

F．Experts suggest taking a break from exercising if signs of your illness appear “below the neck”

G．Exercising regularly keeps us feeling exhausted

4 . Spring and summer are the best seasons of the year for lots of activities, especially jogging(慢跑). This kind of running is the choice of many people who live in the city, work in the office and want to keep healthy.     1    

1. Make good preparations before jogging.

    2    There, you’ll have an opportunity to find and buy all the necessary sportsware. Pay attention to the selection of jogging shoes, if you don’t want to suffer from the feeling of heaviness, pain and leg swelling after the run. With all these pieces of wisdom. your body will be truly grateful to you.

2. Do fitting warming-up activities

Every runner, especially the beginners should know that all physical activities without proper warming up can cause a terrible pain and result in harm to muscles. It will probably lead to a final discomfort in your body or even disease.     3    Actually, it usually just takes you 15 minutes to increase the range of motion of our joints and warm up every muscle of the body.

3.    4    When running, you usually feel physical and mental pleasure. Sometimes this pleasure can be replaced by negative feelings or even some kind of pain. No matter how healthy you’re, you should always pay attention to how your body reacts. If something is wrong during your jog or run, the body will certainly let you know by giving you some hints(暗示). Watchfulness can help you avoid all possible aftereffects of over exercise.

Every type of sport is special and useful in its own way. While jogging can sometimes bring pain and discomfort, it really offers you greater joy and satisfaction. So don’t step back.    5    I hope these tips will help you prepare yourself for jogging and avoid any serious issues.

5 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses （球场） in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

There are many environment-friendly sports. Power walking is one of them that you could take up today. You don’t need any special equipment except a good pair of shoes; and you don’t have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be “green gyms”. They are better replacements for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it’s free.
