Are children becoming addicted to the Internet?

    Children are becoming addicted to the Internet and for many it is one drug that can't be beaten. Not all children, but an alarming number of them are being swept up in this age of digital information.

    Websites like Myspace, Youtube, and Facebook, are becoming so popular that many kids can't help but to be addicted to them just in order to fit. Why not become part of a society where you judged by how many friends on a friend list ? What has become of the world , when instead of calling your best friend on the phone you send them a message electronically and wait around for hours to see if they get on and read it ?Often on the web there just aren't enough adults setting kids straight and too many teenagers causing trouble .

    However, it is biased to claim all kids are addicted, or even that all kids who are addicted to the web are negatively affected by it. While the web can be a large waste pool of negative influence, it is also a wealth of positive knowledge, friendly social networking, and even gateways to future employment. Perhaps it isn't so important whether or not a child is addicted to the web and more important that parents know exactly what the kids are doing there.

    Many computers have optional parent controls that allow parents to block the children from entering certain types of sites, or even individual ones. Such programs are unfortunately not used enough by today's parents, who in many cases are caught up on computers themselves. All one needs to do is google search parental controls and you will be provided with any number of companies that can help with programs for tracing child activity and, if necessary, limit time spent on the Internet .

    Many people may not find the idea of visiting Beijing's Forbidden City just to see its cultural relics(遗迹)very exciting. But what if you got to see deer there too? That certainly sounds like a better day out.

    Nine deer were introduced into the Forbidden City, also known as the Palace Museum, on Sept. 26 and would make it their home until February. The beautiful animals are part of an exhibition on deer-related relics, including furniture, clothes and artworks. In ancient China, deer patterns(图案)could be seen on lots of items since lu—deer—were considered to be a lucky animal because the Chinese word shares the pronunciation(发音)of the character that means “official salary(俸禄)”.

    The deer in the Palace Museum are not only to be part of the exhibition, but also to act as ambassadors(大使)to attract visitors. “It's a better way to bring cultural relics closer to the people,”explained Wang Yamin, a deputy director at the Museum, according to ChinaDaily.

    Turning itself into a zoo is the latest effort that the museum has made at introducing academic(学术的)art to ordinary people.

    In 2014, for example, the museum's online store started to offer products such as T-shirts featuring the pattern of an emperor's coat, and earphones looking like the necklaces worn by ancient officials. These products soon gained popularity on social media because they allowed people to wear a piece of history.

    Two years later, the TV series MastersintheForbiddenCity(《我在故宫修文物》)lifted the mysterious veil(面纱)on the experts who work in the museum—people whose job is to repair the relics within it. And while many of us may have imagined these workers to be old and boring, they're actually quite young and interesting. Some are even in their 20s. They lead a peaceful career, although it can sometimes be dull. Workers aren't allowed to wear any make-up or do their nails(指甲)because the chemicals(化学物质)may damage the relics they're working on, for example.

    Little by little, the Palace Museum is shaking off the stereotypes(刻板印象)of being an old-fashioned academic institution. As Shan Jixiang, the museum's director, once said, “Academic research is not alien from the public's interest. We'd like to make visiting the museum a part of people's daily lives. ”

    It looks like the Forbidden City isn't so forbidden after all.

    Explorers had been landing in America for some time before English settlers arrived in what is now Jamestown, Virginia, in 1607. But it was in that spot on the James River that English colonization(殖民化) began, and with it, the history of America.

    James I was the king of England at that time, and he had granted approval for a group of businessmen who were part of the Virginia Company to settle in this new land. In all, 214 people set sail for America. They reached it on May 14, 1607. Very soon after they landed, the English found themselves under attack from Algonquins, a native American tribe(部落) who had been living in that area for some time. The English managed to drive off the attackers and stay there.

Under the leadership of Captain John Smith, the English built a fort(城堡)and other buildings designed to protect their new colony. They also found friendly native Americans, like Powhatan, who was willing to trade with them.

    There was a terrible winter in 1609 and only 60 of the 214 settlers survived, which was also hard on Powhatan's tribe and other neighboring native Americans.

    One of the main crops grown by the English settlers was tobacco, which they sold to native Americans and to people back in England, beginning in 1612. Tobacco became a very popular crop because it was easy to grow and because it brought in so much money.

    Once the money started flowing in regularly, the Jamestown colony grew, as did other settlements in Virginia and in other states along the eastern coastline.

    America's first elected assembly (议会), the House of Burgesses, met in Jamestown for the first time on July 30, 1619. The year 1619 also saw another significant development: the first arrival of black workers on boats from Africa. These men and women were originally servants, who worked a small piece of land for a few years and then got to keep the land as owners. Jamestown was also the capital of Virginia and remained so until 1698.

    The first newspapers were written by hand and put up on walls in public place. The earliest daily newspaper was started in Rome in 59 BC. In the 700's the world's first printed newspaper was published. Europe didn't have a regularly published newspaper until 1609, when one was started in Germany.

    The first regularly published newspaper in the English language was printed in Amsterdam in 1620.In 1621, an English newspaper was started in London and was published once a week. The first daily English newspaper was the Daily Courant (每日新闻).It came out in March 1702.

    In 1690, Benjamin Harris printed the first American newspaper in Boston. But not long after it was first published, the government stopped the paper. In 1704, John Campbell started The Boston Newsletter (波士顿新闻通讯), the first newspaper published in the American colonies. By 1760, the colonies had more than thirty daily newspapers. There are now about 1,800 daily papers in the United States.

    Today, as a group, English language newspapers have the largest circulation (发行量) in the world. But the largest circulation for a newspaper is that of the Japanese newspaper Asahi Dhimbun (朝日新闻).It sells more than 11 million copies every day.

    An exciting landing process of Chang'e-4 lunar probe (月球探测器 ) was seen through the monitor at Beijing Aerospace Control Center in Beijing, Jan. 3, 2019. It touched down on the far side of the moon at 10:26 a.m. Beijing Time, becoming the first spacecraft soft-landing on the moon's unknown side never visible from Earth.

    China's Chang'e-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control. The relay satellite, named Queqiao, meaning Magpie Bridge, after a Chinese legend (传说) , was launched on May 21, 2018, and became the first communication satellite operating in the halo orbit, nearly 500,000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used for scientific and technological experiments. The maximum distance between the satellite and the Chang'e-4 probe on the far side of the moon is 79,000 km. The satellite processes data from the probe and sends it to Earth.

    The satellite can stay in its orbit for a long time due to its relatively low fuel consumption, as the earth's and moon's gravity balances its orbital moving. While in orbit, it can "see" both the earth and the far side of the moon.

    The concept of using a relay satellite in the halo orbit was first put forward by U.S. space experts in the 1960s, but was realized by Chinese space engineers.

    Researchers hope to use the cameras on the satellite to record asteroids (小行星 ) hitting the far side of the moon. To control the cost of the Chang'e-4 probe, the relay satellite was designed to be relatively small, weighing about 400 kg.

    Researchers had just 30 months to develop the satellite, putting them under high pressure. To promote public interest in space exploration, the China National Space Administration invited people to write down their wishes for lunar and space exploration, and the relay satellite carries the names of tens of thousands of participants and their messages.

    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.
