Music is an international language. The songs that are sung or played by instruments are beautiful to all people everywhere.

    Popular music in America is what every student likes. Students carry small radios with earphones and listen to music before class, after class and at lunch. Students with cars buy large speakers and play the music loudly as they drive on the street.

    Adult drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, politics, and activities of the American people. But most of the radio broadcast is music.

    Pop or popular music singers make much money. They make a CD or tape which radio stations use in every state. Once the popular singer is heard throughout the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.

    Besides pop music, there are two other kinds of music that is important to Americans. One is called folk music. It tells stories about the common life of Americans. The other is called western or country music. This was started by cowboys who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.

    Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined (限于) to the aged. There may be a million or more people under the age of 65 suffering from the disease.

    At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic (器官的) disease, that destroys brain cells.

    Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, and then the patient's memory begins to fail. He may forget dates, numbers, names and plans.

    As the disease progresses, the patient may not recognize family and friends. These symptoms(症状) often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior.

In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk.

    Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus (病毒). It may be caused by a poisonous substance(物质) in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease.

    If you have come to Britain, there are some beautiful places you can't miss. Below are four that you can enjoy during your trip to Britain.

    Cotswolds

    The Cotswolds are a range of hills measuring about 2,000 square kilometers, designated as an area of outstanding beauty and shared by countries of Somerset, Wiltshire, Oxfordshire, Gloucestershire, Warwickshire and Worcestershire. Sometimes known as "The Heart of England", the hills are small but perfectly formed and dotted with pleasant towns and well-preserved old villages inhabited mainly by well-preserved old English folk.

    Bath

    Bath is a historic Roman and Georgian spa city. It is a World Heritage (遗产) site, situated in 100 miles west of London and 15miles southeast of the nearest big city, Bristol. A unique city, Bath is famous for its hot springs, Roman period baths, medieval heritage and stately Georgain architecture. The famous English writer Jane Austen spent some time there, and her novel is a satire of the social life of the city at the time. Many of the sites she mentioned are still able to be visited in the city today.

    Much Wenlock

    The Shropshire town of Much Wenlock is a characteristically English town, off the beaten track, but well worth a visit. Not only is Much Wenlock a stunning beautiful medieval town, but it also played a part in the birth of the modern Olympic Games. Much Wenlock is the birthplace of William Penny Brookes, the inspiration for the modern Olympic Movement and founder of the Wenlock Olympian society. In recognition of its sporting heritage, the 2012 London Olympic Games named one of their mascots Wenlock.

    Castle Combe

    Nestled in a wooded Cotswold valley, with the ambling Bybrook River flowing through its heart, Castle Combe is a truly delightful example of the traditional English village. Architecturally, little has changed since the 15^th century. There are no street lights or TV aerials and you enjoy the peaceful atmosphere, and you will understand why it has won the "Prettiest Village in England" award so many times. Castle Combe is also a favored location for Hollywood film and television companies.

    Who doesn't want to live life in style? Life is like a road on which you never get a chance to return, and is not a very long road either. So we should try to live life to the fullest and enjoy every bit of it.

    Every individual has unique likings and preferences, and all of us try to live the lives that suit us best. The world is like a painting cloth on which different people with different races, different languages, and different cultural backgrounds interact. But among these, the arts provide an easy and natural way for people to connect.

    People with a knack for the arts usually discover it in childhood. But art isn't only for the talented; it can help everyone grow. Those with a strong artistic background are often more energetic, and more successful in all fields of life. Art widens the range of a person's life.

    Painting is one of the most popular art forms. Those who are interested in taking it up as a career need to go through extensive training to get familiar with the various styles. Professional painters often host art exhibitions, with art lovers from all over the world coming to see and buy their creations. Sometimes the paintings are sold at high prices.

    Performing arts are equally popular and admired. Dance, instrumental music, drama and so on require unusual artistic talent as well as a long period of education and training before audiences start to applaud the performances. But anyone with some artistic sense can make art part of his/ her life, and benefit from it.

    More primary care doctors in a community (社区)appear to lead to improved life expectancy for people living there, though a lack of such physicians across U.S. could be a cause of concern for overall population health in years to come.

    For the study, researchers looked at physician counts per 100,000 people in a range covering 2005 to 2015 in the U. S., along with life expectancy and specific causes of death. They found that an increase of 10 primary care physicians per 100,000 population was associated with a 51. 5-day increase in life expectancy, while an increase of 10 specialty physicians per 100, 000 population increased life expectancy by 19. 2 days. An increase in primary care physicians also was associated with reductions of many deaths including heart diseases and cancers.

    Along with those findings, though, the study said many communities did not have primary care physicians in 2015, with the decline in supply more prominent in rural areas than their urban areas. Many believe that a well-functioning health care system requires a solid foundation of primary care, however, payment difference between primary care and technical specialties continue to dispirit the U. S. primary care physician workforce.

    "Higher pay and lifestyle preferences lead most students to choose non-primary care fields, even when their hearts say primary care," the study said. "We must turn this trend around with practical changes in physician payment policy; no amount of superb primary care training or creative practice reform will prevent further declines in primary care physician, which will lead to worsening health for the United States."

    The study's researchers conclude that future research should focus on the "quality and cover of primary care, types of primary care physician training and service offerings, and effective access rather than just supply".
