An Australian researcher is urging parents to load up their teenager’s backpack and make them walk to school.
Professor Leon Straker says students who walk or cycle to school are less likely to have back and neck pain. But the study of 1,202 Western Australian 14yearold found that 72% of students travelled to school by car or bus. Straker says the study suggests walking or cycling while carrying a schoolbag helps improve trunk (躯干) and spinal (脊柱的) muscle strength.
This helps reduce back pain because greater muscle strength improves support for the back during load carrying .Despite advocating that parents get their children moving，Straker warns bag load should not exceed (超过) 15% of body weight.
Straker says the study also stresses that neck pain is as common as back pain among young teenagers. This is an area that has been largely ignored，he says，but can be an important indicator of neck pain into adulthood.
For the study，students were asked a series of questions such as how long they carried their bags for，how they carried their schoolbags，the method of travel，and their perceptions(感觉) about the bag’s weight.
Straker says about half of all participants experienced back and neck pain，with slightly more females reporting neck pain. However，the gender (性别) difference may also be due to the fact that females have lower pain tolerance.
Studies from the 1980s found carrying a bag over one shoulder was most common among teenagers. However in this study 85% of participants carried their bag over both shoulders.
Straker believes the change has been driven partly through education campaigns，but also by increasing fashion status of backpacks and improved design.

A．reduce the load of their children’s schoolbags

B．put more books in their children’s schoolbags

C．get their children’s schoolbags ready for school

As hand-held devices such as smartphones are becoming more common, users are reporting some new physical problems. Florida chiropractor Dean Fishman began noticing an increased number of patients talking about neck and shoulder pain. He discovered these symptoms were due to the overuse of hand-held devices, particularly the action of bending the neck, and then coined the term “Text Neck.” As if the painful symptoms weren’t bad enough, Fishman warns that an untreated case of Text Neck could lead to permanent spinal(脊椎) damage.
Other doctors have warned about “iPad Hand,” a condition that occurs when people use tablets like the iPad for hours at a time. Most people use their left hand to support the tablet and their right hand to tap or scroll. Doing this for long periods without changing positions can result in severe joint pain.
In order to avoid or reduce the possibility of getting Text Neck or iPad Hand, use the following basic ergonomic(人体工学的) principles:
Avoid awkward positioning. Don’t strain your neck, and stay aware of how you are positioned in relation to the device. Make sure that both your neck and shoulders are relaxed and that you aren’t leaning over for a long period of time.
Take frequent breaks when using any kind of mobile device. Many doctors recommend that users change their position every 15 minutes.
When using a tablet, use a case that can support the device on a table or your lap at a comfortable viewing angle.
Along with a case, use a separate keyboard with your tablet. This will be more comfortable since you’ll be resting both hands on the keyboard. And since you won’t be holding the tablet, you’ll be less likely to experience hand or arm pain.
小题1:What kind of product for hand-held devices does the writer discuss?

The World Health Organization recently reported that the number of cases of tuberculosis(TB) has been abating since 2006 . Also, fewer people are dying from TB. But a study by researchers at the University of California, San Francisco, says smoking could threaten this progress.
Nearly twenty percent of all people use tobacco, and millions of non-smokers get sick from breathing the smoke. The new study predicts that smoking will produce an additional thirty-four million TB deaths by 2024.
Efforts to control the spread of TB have mainly focused on finding and treating infections. Fewer efforts have been made to understand the causes. Dr Anthony Fauci is the director of the United States National Institute of Allergy and Infectious diseases. He said, “Despite our control efforts, we still have more than a million people each year dying from TB and millions of people getting infected; we realize it’s still a very important problem. So we have to do the practical thing and we have to do the fundamental research things at the same time. ”
Smoking does not cause TB; bacteria cause the infection. But the study says smoking affects the nervous system in a way that makes an inactive case of TB more likely to develop into an active one. Stanton Glantz is the director of the University of California’s Centre for Tobacco Control Research and Education and an author of the new study. He says it shows that TB cannot be controlled unless tobacco use is controlled. He said, “It increases the number of people who will get TB by about seven percent.”
The study is described as the first to identify a direct link between tobacco use and rates of TB infection and death. Professor Glantz says the results should guide those creating health policies and TB control efforts. He said, “If you want to control the infectious disease of TB, you have to control the tobacco industry and the tobacco industry’s efforts to increase tobacco use, particularly in developing countries where TB is a big problem.”
小题1:What would be the beat title for this passage?

A．Scientists try to find the causes of TB deaths.

B．Study shows smoking is harmful to our health.

C．Study links smoking to millions of TB deaths.

D．Scientists pay more attention to TB deaths than before.

小题2:What does the underlined word “abating” in Paragraph 1 mean?

A．Responding

B．Surviving.

C．Rising.

D．Falling.

小题3: What would Dr Anthony Fauci probably agree with?

A．More efforts are needed to find the causes of TB infections.

B．TB infections are no longer a serious problem.

C．Few efforts have been put into the work of treating TB infections.

D．The practical and the fundamental research cannot be done together at present.

小题4:It is implied in the passage that ____________.

A．it is not very hard to control TB

B．smoking indirectly leads to TB

C．an inactive case of TB is deadly

D．people cannot blame smoking for TB

UGG boots have been a winter-weather fashion for several years now, combining function, comfort, warmth and even some style. What many UGG-enthusiasts don’t know is that their boots are a breeding ground for bacteria and cause foot problems.
Doctors believe the boots, which are particularly popular among young teenage girls, are leading to a rise in the number of people suffering pains in their feet and knees.
Dr. Ian Drysdale，head of the British College of Osteopathic Medicine，believes because the foot does not get the proper support on the inside，it will lead to more ankle，knee，hip and back problems. “These boots are not designed for outside wear. Just because something becomes a trend or fashionable doesn’t mean it’s good or right，” he said, “The particular problem with this type of footwear is that it is unsupported. It’s a slipper. You wouldn’t normally expect to be doing outdoor activities from something that’s indoor. If you decide to wear your pajamas outside all. the time, someone will come up and say it’s not a good idea. ” Dr. Drysdale explained that the feet issues become a particular problem among young teenage girls，whose bones are “ plastic ” and developing when they are growing. “ If that structure is developing in an inappropriate way,” he said, “then the ultimate structure will be deformed ”
Mike 0，NeiU, a consultant surgeon, said, “As the foot slides around, you get wear and tear (磨损）on the joints on the inside of the foot The ankle is m the wrong position, the thigh bone also changes position, and you get an abnormal movement in the pelvis, which leads to back problems. ”
UGG AustraUa₉ who makes the designer version of the boots, told The Daily Mirror that their boots are “comfort” rather than “performance” footwear and consumers should be aware of “knockoffs”（仿制品)which lack reinforced heels in their boots.
小题1:Teenage girls prefer to wear UGG boots because of the following except______

A．design

B．comfort

C．quality

D．warmth

小题2:Accordi^ to Dr. Ian Drysdale，_____

A．there is a possibility that bacteria will multiply in UGG boots

B．wearing UGG boots will lead to more ankle and toe problems

C．it’s not a good idea to wear boots like UGG outside all the time

D．teenage girl’s bones are plastic enough to wear UGG boots

Vans, Keds, Dollies—they sound like the names of rock bands, but if you have teenagers, you'll know they're actually the latest in teenage footwear.
But experts are now warning that the latest shoes in different styles will be causing teenagers discomfort(不舒适） in the short term and storing up years of foot, knee and back pain in the future.
Here, the experts discover the problems caused by teenagers' shoe choice.
KEDS/VANS

Slip-on shoes with elastic (弹性的) sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.
The main problem is that they are just too flat—so flat that the heel, which hits the ground first, also becomes damaged and painful.
BALLET PUMPS

The worst shoes of all are such light and thin dolly shoes. The problem is partly their flatness, as with Keds and Vans. However ballet pumps, which have no string or heel, have other specific problems.
“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing a difficult gait（步法）, this leads to short- and long-term problems such as calluses（茧子）, heel and knee pain.”
WEDGES AND STILETTOS

These shoes can also cause problems with gait. They may look good, but the heels on these are so high they can force the wearer's body weight forward, making them very shaky.
Teens who wear these shoes regularly are also in danger of joining those millions of women with continuous back pain.
SCHOOL SHOES
So what do podiatrists（足科医生）have on their wish list, especially for everyday wear?
Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark's, Marks & Spencer or Rhino.
If your teen insists on wearing 'bad' shoes, get them some simple foot orthotics(矫形器) in the shoes. These support and correct the movement of the foot and, properly fitted by a podiatrist, can often change their walk and halt the damage.
小题1:Of all the shoes mentioned(提到) in the passage, which can cause the worst problems?

A．Marks & Spencer.	B．Wedges & Stilettos.
C．Keds and Vans.	D．Ballet Pumps.

小题2:Which pair of shoes may not be found on the podiatrists’ wish list?

A．

B．

C．

D．

小题3:The underlined word “halt” in the last paragraph probably means _______.

A．increase

B．worsen

C．stop

D．cause

小题4:In which column of Mail Online can you find this passage?

A．Sports.
