1 . If you’re tired of freestyle walking programs, you may be interested in learning how to racewalk. Or you want to pick up speed. Or maybe you have a desire for competition.     1    , racewalking is a good choice for you.

As you begin to racewalk, it is important to concentrate more on movement than on speed. Speed will come later, as you master the movement skills of racewalking. And you can begin to increase your speed once you feel comfortable with the actions of racewalking. Be sure, however, to increase your speed gradually.     2    .

Racewalking can increase your walking exercise. You can experience this in person. Try walking as fast as you can, and youll feel your body eager to jog.     3    , you have to keep one foot on the ground at all times. While you are jogging, both feet are off the ground at some point, which allows you to cover more distance with one step. So in order to cover the same distance, you have to take more steps than you would if you were jogging.

    4    . Before you begin exercising, you need to warm up your body and relax your muscles (肌肉).     5    . It is necessary to cool down in the end. If you ignore these steps, you may suffer muscle pain and even injury.

A．No matter what the reason is

B．In order to walk at high speeds

C．The same is true after each exercise

D．Always keep safety in mind when racewalking

E．In order to continue walking and not to break into a jog

F．Don’t push too hard or walk to the point of being tired out

G．It is more efficient to warm up your body before exercise

2 . Older women who walk a little over three kilometers each day might live longer than less active women of the same age, a new study suggests.

Many Americans hoping to stay healthy set a daily goal of 10, 000 steps, or about eight kilometers. They often have this goal because they are wearing electronic devices which set that target, note researchers in the United States. Their findings appeared recently in the publication JAMA Internal Medicine.

But it is not clear how much intensity(强度)or speed matter when counting the health benefits of every step, the researchers write. They add that 10,000 steps per day might not be the right goal for everyone.

For the study, researchers observed 17,000 women, all in their early 70s. They asked the women to wear accelerometers for at least four days. Accelerometers are small devices that measure the number of steps and the intensity of movement. The researchers followed up with the women much later, around 4. 3 years later, on average. Since the beginning of the study, 504 women had died. Compared to women who took no more than 2, 718 steps daily, the women who took at least 4,363 steps per day were 41 percent less likely to die.

“Even a modest amount of steps is associated with lower death rates, "said I-Min Lee, the lead writer of a report on the study. "The rate of stepping did not matter in these older women: it was the number of steps that mattered.

The study had a few limitations. For example, the researchers only measured women’s movements once, at the start of the study period. It is possible that the women’s behaviors changed over time. Still, the results are "good news for older adults who may have difficulty walking at faster paces, "said Keith Diaz, a researcher at Columbia University. He was not involved in the study.

“Any walking is better than nothing, " Diaz said by email. "With even small amounts of walking, your risk of death will be sharply reduced "For those who have difficulty walking, other research shows that any form of aerobic activity provides health benefits," he added. "Swimming, bicycling or any form of activity that is continuous in nature will provide health benefits.

3. What can be leaned from what Diaz said?

A．People who walk fast will get more health benefits.

B．If people have a habit of walking, the risk of death will be reduced.

C．People with walking difficulty can not benefit from activities

D．Activities such as swimming and bicycling are not as beneficial as walking.

4. Where is the text most likely from?

A．A medical journal.	B．A news report.

3 . There are lots of skiing lovers around the world. To get the most out of your time on the mountain you should think through each part of your adventure- equipment, clothing, food, and travel.     1    , the more time you can spend on the slopes.

Equipment

Your skiing equipment — composed of your skis, poles, bindings, helmet, and goggles — should be checked over, and possibly tuned up, before you pack your bags for the mountain.     2    . Inspect your boots to make sure they fit properly. Check your goggles and put them on with your helmet to see that they fit comfortably and offer a wide field of view.

Clothing

Your jacket and snow pants should be properly fitting and recently cleaned. Make sure your gloves are in good shape and offer a sense of comfort.     3    . Don’t forget extra items like warm socks, neck warmers and ski masks as well.

Food

Anyone who has ever purchased lunch at the ski lodge knows just how expensive it can be. Packing your own lunch saves you money and gets you back on the slopes faster.     4    , bring plenty of fluids to drink on breaks between runs.

    5    .

Know your way to the mountain before you hit the road and consider writing down directions if you know you’re heading into areas with spotty service. At the mountain, choose a designated meeting place in case the group becomes separated- a spot near the main lift often works well. Check the forecast and current conditions of the mountain. Many ski resorts will have live updates on the number of open trails and lifts.

A．Routes and planning

B．Spots and conditions

C．If you are fully prepared

D．The more prepared you are

E．While bringing a bottle of water with you on the mountain isn’t recommended

F．Besides, long underwear goes a long way in keeping your legs warm and comfortable

G．If you are taking your skis onto the slope for the very first time, they may also need a fresh wax
