Runners need to move 15 per cent faster on a treadmill(跑步机) to burn the same number of calories as jogging outdoors, research reveals.

Researchers from Milan University analyzed the difference between running outdoors and on a treadmill in 15 physically fit males with an average age of 21. The participants completed a sprint(短距离快速跑) for 30 seconds followed by 30 seconds of recovery for a total of 15 minutes both outdoors and on a treadmill. Oxygen use and exercise intensity were measured after both types of running.

The findings were published in the journal of Applied Physiology, Nutrition and Metabolism. Results revealed that when on a treadmill, runners use significantly lower amounts of oxygen, suggesting less effort is required. Therefore runners must move 15 percent faster on a treadmill to burn the same amount of calories as exercising outdoors, the study stated. The study authors wrote, "A 15 per cent increase in running speed during a period of stopping and starting often in high intensity treadmill training session is the best possible solution to reaching the same physiological responses as an outdoor training session.

Although the study did not speculate why treadmill running appears to be needing less effort and energy, previous research suggests the moving belt of a treadmill moves joggers forward, causing them to move faster. Exercising indoors also means gym-goers do not have to fight with steep hills or wind resistance.

Michael Silverman, director of rehabilitation and wellness(康复科) at Northern Westchester Hospital in New York, said, “Outdoors, you are changing surfaces constantly, fighting the wind, and making quick and sudden starts and stops, which will lead to increased caloric burn.” Shake magazine reported. "And while we don't recommend running in extreme temperatures, it is worth noting that your body burns extra calories to regulate your body temperature," he says.

A.In Paragraph 2 B.In Paragraph 3 C.In Paragraph 4 D.In Paragraph 5

2.What can we know about the study?

A.Its participants were all 21 years old .

Who could have imagined that a treadmill(跑步机)on wheels would one day become a thing? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

Lopifit founder Bruin Bergmeester says it all started when he asked himself the question. "How can I use a treadmill outdoors?" He eventually came up with a design, to which he added an electric engine, and Lopifit was born. The treadmill bicycle is similar to a typical electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses it when you walk on the treadmill and uses the motor to turn a drive chain at the back part of the treadmill, helping you reach a top speed of 17 miles per hour.

To use the Lopifit, simply turn on the battery and use your feet to slide the treadmill backwards and activate (激活) the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast, all you have to do is stay still and admire the view. To stop, you have two hand brakes available.

The Lopifit first hit the streets in 2014 and, unsurprisingly, became an instant hit. That was actually quite challenging for the company, because it started get inquiries and calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle became available this year, and Lopifit is struggling to keep up with demand, despite the high price tag of $ 2,115.

But despite having a very loyal fan-base of so-called Lopifitters, the creative means of transportation also has naysayers who simply consider the invention stupid and unnecessary. They basically believe that if you’re going to walk, you might as well do it the old-fashioned way. But the Lopifit does have the unique advantage of helping you walk really fast without breaking a sweat, or walking at cycling speed, if you will.

1.With the help of Lopifit, you can ________.

A. cycle to work by walking

B. offer power to any bicycle

C. create a treadmill on wheels

D. answer some hard questions

2.From the second paragraph, we can learn ________.

A. how Lopifit was created

B. where Lopifit can be used

C. who Lopifit is intended for

D. which design is suitable for Lopifit

3.What can be learned from the fourth paragraph?

A. Lopifit was cheap and available in 2014.

B. Lopifit always broke down on the streets.

C. It was hard for the company to design Lopifit.

D. The supply of Lopifit failed to meet the demand.

4.How do the public react to Lopifit?

A. Positively.

B. Variously.

C. Angrily.

D. Cautiously.

One in four Britons would not trust their neighbors to take delivery of a parcel and 10 per cent suspect them of having stolen a parcel in the past, a survey has found.

A study of 2,000 shows that barely half of people know who their neighbors are. A majority would never ask their neighbors to look after such things as keys (68 percent), pets (89 percent) while they were out and even taking in parcels is taking trust too far for more than a third of us (35 percent), according to research for InPost UK.

One in ten (11 percent) have had parcels taken by a neighbor or from right outside their house. When it comes to deliveries, almost a quarter (26 percent) have gone into work late or have left early to wait in for a parcel. This gives rise to people queuing in the Post Office more than 20 minutes to pick up or send a parcel.

As a result, shoppers are looking for more convenience this Christmas. While 83 percent will still get gifts sent to their home, one in five (19 percent) will have parcels delivered to their office and 33 percent will click and collect in store or from a nearby shop.

In addition, almost two thirds of online shoppers (64 percent) are considering using parcel lockers because they provide a local 24/7 service.

Jonathan Smith, chairman at InPost UK, said: “It’s surprising that people don’t trust those closest to them to help them out and to see that missed deliveries are still such an issue, especially as we head into the peak shopping period.”

1.What’s the problem of British delivery parcels?

A. They are always stolen by strangers.

B. Some missing parcels are suspected to be taken by neighbors.

C. Most of the parcels have to be picked up in the post office.

D. Deliveries almost cause 50% going into work late or leaving early.

2.According to the passage, we can learn that 　　　　 .

A. merely half of people know their neighbors

B. only one in four Britons trust their neighbors to take delivery of a parcel

C. a majority would ask their neighbors to look after their pets

D. two thirds of online shoppers still get their parcels sent to their home

3.What’s the attitude of Jonathan Smith towards the issue?

A. Unexpected.　　　　 B. Critical.

C. Overstate.　　　 　 D. Optimistic.

4.What’s the best title for the passage?

A. The delivery problem in Britain

B. How can we trust each other

C. The trust crisis（危机） in neighborhoods in Britain

Like distance runners on a measured course，all of us will move through time in a roughly predictable pattern．

In the first stage of our lives，we develop and grow, reaching toward the top of physical vitality(活力)．

After we grow up，however, the body begins a process of gradually wearing out．

A new awareness of physical fitness may help lengthen our years of health and vitality，yet nothing we do will work to stop the unavoidable force of aging．

Most of the changes of aging take place deep inside the body．The lungs become less able to take in oxygen．Powerful muscles gradually lose their strength．The heart loses power and pumps less blood．Bones grow easier to break．

Finally, we meet a stress，a stress that is greater than our physical resistance．Often，it is only a minor accident or chance infection(a disease caused by virus)，but this time，it brings life to an end．

In 1932，a classic experiment nearly doubled the lifetime of rats，simply by cutting back the calories in their diet The reason for the effect was then unknown．

Today, at the University of California at Berkley, Dr．Paul Seagle has also greatly lengthened the normal lifetime of rats．The result was achieved through a special protein limited diet，which had a great effect on the chemistry of the brain．Seagle showed that within the brain，specific chemicals control many of the signals that influence aging．By changing that chemical balance，the clock of aging can be reset．

For the first time, the mystery of why we age is being seriously challenged．Scientists in many fields are now making striking and far-reaching discoveries．

An average lifetime lasts 75 years，yet in each of us lies a potential for a longer life．If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years．
