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.

As a legally blind student,the first day of school holds special meaning for me.Along with excitement and nerves over new teachers and new classes,that day in each August also affirms my sense of belonging—a sense that lam claiming a right just as other students do when they.board the school bus or walk to campus.
Since it was passed over thirty-five years ago,the Individuals with Disabilities Education Act (IDEA) has required state and local schools receiving federal funding to provide students with disabilities with a free appropriate public education (FAPE).Currently,over 6 million students across the country with various types of disabilities benefit from the IDEA's protections.But parents and school districts have contested exactly what that actually requires.
The case arose,after the parents of Endrew F.,a student with autism,decided his school was not doing enough to educate their son.Each year from preschool to fourth grade,the school district renewed Endrew's individual education goals without making substantial（大量的）changes.This suggested the plan was failing to help make meaningful progress.
Eventually,Endrew's parents enrolled him in a private school,where he improved significantly through a new plan designed to address specific behaviors and goals.When his parents attempted to re-enroll Endrew in public school again,the district offered a version of its previous plan.The school district argued that was sufficient because it provided Endrew "some" educational benefit.
IDEA empowers（使有能力）students with disabilities to aim high with support from school administrators and input from parents.For me,the Act did just that.From preschool through twelfth grade,I received my right to accommodations such as enlarged papers,a seat in the front of the classroom,and support from vision and mobility specialists outside the classroom.At the same time,my parents,like Endrew's,demanded that my disability should not stop me from becoming independent.Each year,they met with school officials to insist on adjustments to my learning plan as necessary.

Haad Farang (Haad Sai Yao),KohMuk
This small but striking bay in Thailand has waters free from riptides（激流）,making it safe for families to play water in the sun.As its nickname implies—Farang is Thai for foreigners—you'll find a large concentration of backpackers here.Still,with only a couple of simple food shops,it's a far cry from the noises of Chaweng beach on Koh Samui or Kamala on Phuket,which makes it to be one of the top tourist destinations.
Rent a sea kayak（皮划艇）(100 baht,which is around￡2 an hour) and go around the comer to Tham Morakot (the Emerald Cave),a winding cave that opens up to a.bay walled by thick leaves and often visited by groups of monkeys.It is very inspiring,but to fully appreciate it,be sure to prepare a light to avoid knocking into cave walls and other kayaks.To avoid being crowded,make the trip in the late afternoon.
Where to eat
The Ko Yao Viewpoint Hotel is the best place for tourists.Drink the sweet cocktails in favour of an icy Chang beer and sit in the last rays of the day.
Where to stay
Cheaper hotels of comparable quality are set slightly back in the forest,but if you want beachfront access it's worth choosing one of the basic hotels at Koh Mook Charlie Beach Resort (bungalows from￡32).
Getting there
Fly from Bangkok to Trang with Air Asia (from￡30),then take a one-hour Tigerline ship from Hat Yao Pier (￡19).Besides,a five-hour ship from Phuket at Rassada Pier(￡41) goes directly to the island and will drop passengers at Haad Farang.
