    Probably no other musical instrument is as popular as the guitar around the world. Musicians use the guitar for almost all kinds of music. Country and western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. And rock and roll music would almost be impossible without this instrument.

    Music experts do not agree about where the guitar was first played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than 1,000 years ago. Most experts say that the ancestor of the modern guitar was brought to Spain from Persia sometime in the 12^th century. The guitar continued to develop in Spain. In the 1700s it became similar to the instrument we know today.

    Many famous musicians played the instrument. The famous Italian violins Niccole Paganism played and wrote music for the guitar in the early 1800s. Franz Schubert used the guitar to write some of his famous works. In modern times Spanish guitarist Andres Segovia helped make the instrument extremely popular.

    In the 1930s, Les Paul began experimenting to make an electric guitar. He invented the solid-bodied electric guitar in 1946. The Gibson Guitar Company began producing its famous Les Paul Guitar in 1952. It became a powerful influence on popular music. The instrument has the same shape and the same six strings (弦) as the traditional guitar, but it sounds very different. Les Paul produced a series of extremely popular recordings that introduced the public to this music. Listen to this Les Paul recording. It was the fifth most popular song in the United States in 1952. It is called “Meet Mister Callaghan.”

    Are you looking for something to do? You might like to try one of these four experiences.

    Crocodile watching

    Do you fancy getting up close to some of the most terrifying animals on earth? Crocosaurus Cove, in Darwin (Australia) has the “Cage of Death”. It's an enclosure that's lowered into a pool. This gives you a 360 degree view of a crocodile as it's being fed. The cable broke once and the cage sank to the bottom, but they've fixed it since then.

    Edge walk

    How about walking along the edge of a building several hundred meters up in the air? If that sounds like fun, head off to the CN Tower in Toronto (Ontario, Canada). Built in 1976, the tower is 553.33 meters tall.

    The Edge walk consists of a 20-30 minute stroll along a 1.5 meter wide platform that runs around the tower's restaurant roof. During the walk, you're encouraged to lean forwards as you look over Toronto's skyline (轮廓线).

    Plastic ball rolling

    Do you fancy rolling down a hill in a plastic ball?

    Plastic ball rolling is popular all over the world, but the place to give it a go is in Rotorua (New Zealand). Brother David and Andrew Akers came up with the idea in 1994. A typical orb(球) is about 3 meters in diameter, with an inner orb size of about 2 meters. There's no brake or steering mechanism, but the inner layer of the plastic ball helps absorb the shock.

    Volcano bungee jumping

    If you're looking for the adventure of a lifetime, how about going bungee jumping off a helicopter into the crater of a live volcano? As part of the jumping, a helicopter ride takes you to the Villarreal volcano, one of the most active in Chile. Once you're at the drop zone, you leap off the helicopter and fall into the volcano. Finally, you enjoy the ride back to the airport flying at 130kph.

    With its snow-covered mountains and a variety of wildlife, Yellow Stone National Park is one of the scenic treasures of the United States. Located primarily in Wyoming, the park hosts millions of visitors every year. If you plan to travel within the park, keep in mind advice from the National Park Service.

    Seasonal Travel

    Travel varies vastly from season to season. Roads are generally open in the summer except for cases of rock or mud slides, wild fires, accidents or road construction. Early snows in the fall can cause some roads to close temporarily. In the winter almost all roads are closed to motor vehicles, but snowmobiles and other snow vehicles with tracks are allowed. Roads begin to open for the spring by the latter part of April but can close if snowfall continues.

    Driving Time

    Grand Loop is the main road through Yellowstone National Park; it passes by most of the major attractions. These include Old Faithful, Yellowstone Lake and the Grand Canyon of Yellowstone. The maximum speed limit on the Grand Loop is 45 miles per hour, but the speed limit drops during some of the winding and twisting sections of this narrow road. Allow yourself at least two days to fully travel the loop due to the size of the park and being sometimes stuck in heavy traffic.

    Safety Awareness

    Buffalo(水牛)often block the roads in the park as they move through the fields. If a group is traveling across the road you are on  you can either wait for them to pass or find an alternative route. If you get out of your vehicle, the National Park Service says to stay at least 25 yards from any buffalo (and 100 yards or more away from bears and wolves). Buffalo are particularly unpredictable and charge people at speeds up to 30 mph.

    You can take your bicycle on any public roads and routes designed for bikes, but bicycles are not allowed on the park roads which are narrow with few shoulders. Altitudes range from 5, 300 to 8, 860 feet. The National Park Service recommends cyclists wear helmets and noticeable clothing.

Vitamin D was recognized a century ago as the cure for rickets, a childhood disease that causes weak bones. Then, in the early 2000s, a pile of studies suggested that low vitamin D levels could be a factor in cancer, cardiovascular（心血管） disease, Parkinson's disease and so on. This simple vitamin seemed to be a cure for whatever troubled us. However, all these observational studies have a fundamental weakness: they can identify a co-occurrence between vitamin D and a disease, but they can't prove there is a cause-and-effect relation.

To look at whether taking vitamin D had curative effects, Manson and her team started the world's largest and most far-reaching randomized vitamin D trial. The study followed nearly 26,000 healthy adults, randomized to receive either 2,000 international units （IU） of vitamin D or a placebo（安慰剂）, for an average of 5.3 years. The volunteers were almost evenly split between men and women, and 20 percent of the participants were black.

The results came as a shock. Not only did vitamin D not reduce rates of cancer or heart disease, but the trial also found that vitamin D did not prevent or improve cognitive function, or reduce the risk of bone fractures（骨折）. The finding about fractures "was a real surprise to many people," Manson says.

In 2011, the Institute of Medicine established an expert committee to conduct a thorough analysis of all existing studies on vitamin D and health. The committee concluded that the bone-strengthening benefits of vitamin D remain steady when blood levels reach 12 to 16 nanograms per millililter. They also found that there were no benefits to having levels above 20ng/ml. According to measurements of vitamin D levels in the general U. S. population, most had levels of 20 ng/ml or more in 2011. Levels have actually risen since then, meaning that most people don't need to take extra vitamin D.

The ups and downs of vitamin D offer a lesson in humility. The relation between the vitamin and disease is far more complicated than it first seemed and a reminder that scientific understanding is always developing over time.
