Vitamin D is essential for bone-building,cognitive function,joint health,immune function,blood sugar control, positive mood and more.It can help prevent many diseases.Some studies suggest that the lower your vitamin D level is,the higher your risk of death from any cause will be.However,it's not a great idea to just grab a supplement（补充物）off the drugstore shelf and start taking it.

Since many of us are deficient in vitamin D,also known as the "sunshine vitamin”,doctors will often give us a prescription（处方）for high levels of vitamin D supplements,with doses ranging from 2,000 to 10,000 IU (International Units) per day,up to 50,000 IU per week,and sometimes even more.But like all good things,it's possible to get too much of it."Very big doses of vitamin D can cause a build-up of calcium in the blood,which leads to nausea,vomiting,poor appetite,weakness,and weight loss,"says Madeline Basler of Real You Nutrition.Here's the bigger issue: any extra intake of,vitamin D can get stored in the body."A build-up of stored vitamin D can cause avoidable problems,"says Marra Francis,Medical Director at Everly Well,"leading to problems such as kidney stones."

The average daily recommended amounts vary based on your age.The National Institutes of Health set the Recommended Dietary Allowance for vitamin D at 600 IU daily for infant,children,and adults up to 70 years old. Adults aged 71 and older need 800 IU,since the ability to absorb vitamin D drops with age.People who are obese may also need more vitamin D because the fat cells take it up,making it less available for use by the body.In winter when you're getting less sun exposure,some experts say it's safe to take daily doses of around 1,000 to 2,000 IU without any risk of complications（并发症）.

Though you'll get a bit of vitamin D from foods—including fatty fish beef liver,cheese,egg yolks and mushrooms,plus fortified foods like milk,orange juice,and cereal—the amounts are so small that there's little need to worry that they’ll put you over the daily does.

1.What can we infer from Paragraph 1?

A. We can actually reduce the risk of death.

B. People don't really know vitamin D well.

C. Vitamin D supplements are necessary for everyone.

D. Vitamin D should be supplemented carefully despite its importance.

2.The underlined part "are deficient in" in Paragraph 2 probably means “　　　　 ”.

A. having an inadequate amount of　　 B. paying much attention to

C. being interested in　　 D. being concerned about

3.How much vitamin D should a healthy 60-year-old lady take daily in summer?

A. About 800 IU.　　 B. About 600 IU.

C. No less than 1,000 IU.　　 D. No less than 5,000 IU.

4.What does the last paragraph mainly talk about?

A. What other ways people can take to get vitamin D.

B. What foods we should eat every day to balance our diets.

C. Whether daily foods would overdose people with vitamin

D. D.Whether vitamin D can be supplemented by the foods we eat.

New Zealand is located where two tectonic plates of the earth's crust meet. This causes a large amount of geothermal activity, allowing warm water to bubble up through the earth's crust to form hot pools. These pools often contain minerals dissolved from the rocks they seeped through.

Here you will find a selection of commercial and wild hot pools throughout New Zealand.

Rotorua

In Rotorua, a city built on top of an active volcanic zone, nearly every accommodation establishment offers private, exchange-heated spa pools. You'll also find a selection of hot pool complexes, including Hells Gate and the Polynesian Spa.

Near Reporoa is a hot spring called Butcher's Pool. Rated highly by regular soakers, this free-of-charge pool is owned and maintained by the Rotorua District Council. It has sealed walkways, toilets and changing rooms.

Lake Taupo

Lake Taupo is home to a range of naturally-heated hot pools-perfect for a relaxing soak after a busy day of exploring.

Long time local favorite, Taupo DeBretts Hot Springs offers heated indoor and outdoor pools while Tokaanu Thermal Pools offer private and public hot pool experiences.

If you're looking for a thermal soak and massage in a quiet setting, head to Wairakei Terraces and if you'd like to explore some of the region's thermal pools without pulling out your wallet, head along to either the Lake Terrace or Spa Park.

South Island-Hanmer Springs

There are fewer hot springs in the South Island, which has very different geography to the North Island. However the huge Alpine Fault that created the Southern Alps has done the world a favour with Hanmer Springs, an all-seasons hot spring resort that regularly wins awards for its facilities. At Hanmer you'll find thermal mineral, sulphur and freshwater pools, as well as a large children's activity area with water slides. Beauty and massage treatments put the finishing touches on your relaxation.

If you'd like the unique experience of bathing in heated glacial waters, head to Tekapo Springs. Or soak in fresh mountain water and glorious alpine views at the outdoor Omarma Hot Tubs, just 90 minutes from Aoraki/Mount Cook.

1.Which hot pool near Lake Taupo is free of charge?

A.Taupo DeBretts Hot Springs B.Tokaanu Thermal Pools

Childhood obesity puts kids at risk for cardiovascular disease, bone and joint problems, sleep apnea, and potential social and psychological problems. 1.

Of course, the CDC recommends healthy lifestyle choices—healthy eating, physical exercise. 2. That is to provide a safe and supportive environment where healthy lifestyle choices can be made.

What don't kids need?3.Too much focus on overweight leads toward more weight gain.

A new data analysis of two studies found that children whose parents considered them to be “overweight" tended to gain more weight over 10 years than children whose parents considered them “normal weight". Children whose parents label them as “overweight" had a negative self-perception about their bodies. They were engaged in more attempts to lose weight. 4.

The clear message from this study is that dieting is more likely to lead to weight gain, not weight loss, in both children and adults. Psychology researchers Eric Robinson and Angelina Sutin argue that the stigma of being labeled overweight as a child might actually gain weight in the future.

5. For the study, children's height and weight were measured at age 4 or 5, and parents were asked to describe whether they thought the children were best described as underweight, normal weight, overweight or very overweight. When the children were 12 or 13, they used images to best depict what they perceived their bodies to look like and were asked whether or not they engaged in any dieting behavior. Height and weight measurements were taken again when the children were 14 or 15 years old.

A.Labels and pressure around weight and weight gain.

B.Left untreated, these problems can continue into adulthood.

C.They also point out another important way to keep kids healthy.

D.The researchers cannot be certain about what is driving.

5 Lifestyle Choices You Will Feel in Your Bones

YOU SPEND TOO LITTLE TIME ON THE MOVE

"Bone is a living tissue," says Jonathan Lee, a physician at Montefiore Health System in New York City. "The more you use it, the more it will adapt and strengthen. Likewise, if it is not subjected to loading, it will waste away. " The solution? Weight-bearing exercise-even just walking. Strength training Counts too

YOU EAT SALTY SNACKS

A study from Japan showed that women over fifty who had high sodium (钠) intakes were more than four times as likely to have a fracture (break of.bones) as those with low sodium intakes. That's because as the kidneys(肾) excrete(排出) the sodium, calcium is reducing from the bloodstream too.

YOU SHUT SUNLIGHT AWAY

" Vitamin D is required for the body to successfully absorb and use calcium," Dr. Lee says. "Most Americans do not get enough sun exposure to generate enough natural vitamin D, and thus supplementation is essential. " According to the National Osteoporosis Foundation, adults under 50 need 400 to 800 IU of vitamin D daily and adults 50 and older need 800 to 1,000 IU. Talk to your doctor about your specific needs based on where you live, what time of year it is, and which vitamin D-rich foods you eat.

YOU'RE CASUAL WITH WINE

Low levels of alcohol consumption may be good for your bones, according to a study from Oregon State University, but more than a couple of drinks a day has the opposite effect. "Too much alcohol can make it harder to absorb calcium," says Dr. Lee. Furthermore, "In women in particular, higher alcohol consumption can decrease estrogen (雌激素） levels, and this can also lead to osteoporosis(骨质疏松) , " Dr. Lee says.

YOU LIVE IN AN AREA WITH DIRTY AIR

In a study recently published in the Lancet Planetary Health , researchers dealt with hospital data for 9.2 million Medicare participants in the Northeast and mid-Atlantic between 2003 and 2010. They found that even a small increase in levels of pollutants in the air--may lead to an increase in bone fractures and osteoporosis in older adults. If you live in a smoggy area,use an air purifier filter at home, avoid exercising outdoors when the air quality is bad,and get screened for osteoporosis.

1.According to the article, to have healthy bones, a lady of 65 should　　　　　 　 .

A. form a habit of drinking a bottle of wine every day

B. protect herself from being exposed to sunlight

C. exercise indoors or do little strength training

D. lessen sodium intakes in her diet
