While it may seem like everyone surfs the web these days, there is fine line between casually checking your social media pages and having a full blown Internet addiction. If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction. {#blank#}1{#/blank#}

Admit you are at risk of an addiction.

    More and more people in the world are becoming addicted to the Internet. You are not the only one with this problem; it is becoming more and more common and more and more well known. {#blank#}2{#/blank#}.

Set aside limited time for computer use.

    Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it; {#blank#}3{#/blank#} If you have a desktop PC, try not to go near it or put something over it like a sheet.

Call people instead of sending instant messages or texts.

    If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer. {#blank#}4{#/blank#}

Use an alarm clock or timer.

    Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your desktop. {#blank#}5{#/blank#}.

A. Make a small list of what you want to do within that time.

B. When the computer is not looking at you, you are less likely to use it.

C. This can be programmed to shutdown your computer after the set time

D. Luckily, there are ways to avoid living your life in front of the computer.

E. This will stop you from using the Internet so often or going on to another page.

F. If you have a problem on weekdays, phone your friends or ask for help in person.

G. Do not be embarrassed; find others with the same problem and help each other beat it.

    Now many young people are traveling around the world on their own，not because they have no one to travel with，but because they prefer to go alone.

    Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. ＂It opens up your mind to new things and pushes you out of your comfort zone.＂ Wegscheider has visited 46 countries covering all seven continents.

    In foreign countries，with no one to help you read a map，look after you if you get ill，or lend you money if your wallet is stolen，it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.

    Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website，The Aussie Nomad，to document his adventures. He says he wished he had traveled alone earlier. ＂The people you meet，the places you visit，or the things you do，everything is up to you and it forces you to grow as a person，＂ said the 30-year-old man.

    Richardson describes traveling alone like ＂a shot in the arm＂，which ＂makes you a more confident person that is ready to deal with anything＂. He said，＂The feeling of having overcome something on my own is a major part of what drives me each day when I'm dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.＂

    The great 19th century explorer John Muir once said，＂Only by going alone in silence can one truly get into the heart of the wilderness.＂

    Why are certain people so memorable, while some fade from our memories over time? This question crosses my mind often; there are many possible answers. When you are raising children, you realize that some people become very important to them, draw them in, accept and respect them. These people change them.

    Several examples come to mind with my youngest son. He was always more comfortable around his dad's friends than his own. He loved to spend time with them, fish with them, listen to their stories and just be with them.

    He has experienced the loss of several really meaningful friendships over the past few years, and it has been very painful for him. One, Dr. George, was a neighbor and fishing buddy who would call to see if Ken could go fishing with him. Dr. George always said Ken was the son he never had and that it meant everything to him. He died very suddenly while fishing with all of his best buddies a few years ago. The huge hole that left in so many lives simply cannot be filled — for Ken it was immensely painful.

    There was another fishing buddy of his dad's, Frank, who was always fun to be around. Ken was very young then, but he really enjoyed getting along with ＂the guy＂ when they were fishing. Frank and his family went to the Keys in the same week as we did one year ago and the memory remains to this day. Cheerful and happy, he was able to laugh at himself and accept everyone's abilities or lack of them, all qualities that impressed Ken so much.

    When he became deadly ill, Ken drove from his home in North Carolina to Florida for an overnight visit with him. He died a short time later. The day after his funeral (葬礼), Frank came to Ken in a dream and asked if he would take care of his wife, Carol. To Ken this was very meaningful, and today they share a special bond that Frank somehow knew would be important for them both.

    Scientists are studying different foods, and they will see which foods protect us from cancer(癌症), and which cause it. It is known that a healthy diet(饮食) will help keep a healthy body weight, which can also decrease the risk(风险) of many types of cancer.

    Fruit and vegetables

    Fruit and vegetables are an important part of a healthy diet. They can decrease the risk of some cancer types like mouth and throat cancer. They are a good source of many important nutrients such as vitamin A, vitamin C, vitamin E, and are an excellent source of fiber.

    Our advice

    Try to get plenty of fruit and vegetables in your diet. Eating fruit and vegetables with a variety of colors will help you get many kinds of vitamins and minerals, as the chemicals that give these foods their colors are good for you.

    Meat

    Eating lots of red and processed meat can increase(增加) your risk of stomach cancer. Red meat includes all fresh and frozen beef, pork and lamb. Processed meat includes ham, bacon and sausage. White meat, such as chicken, is unlikely to increase your risk of cancer.

    Our advice

    Eat smaller and fewer parts of red and processed meat. Try using beans or peas instead of meat in your diet. When you cook meat, use low-temperature methods.

    Fat

    Fat is a necessary part of our diet but high-fat diet can increase our risk of cancer, heart disease and other diseases. Meat is higher in saturated fat(饱和脂肪) and eating too much saturated fat may increase your risk of breast cancer.

    Our advice

    Try not to eat too much fatty foods. In particular, try to cut down on saturated fat contained in fatty meat, biscuits, and butter. Try to avoid frying foods in lots of oil.

    In the mid-1990s, Tom Bissell taught English as a volunteer in Uzbekistan. He left after seven months, physically broken and having lost his mind. A few years later, still attracted to the country, he returned to Uzbekistan to write an article about the disappearance of the Aral Sea.

    His visit, however, ended up involving a lot more than that. Hence this book, Chasing the Sea: Lost Among the Ghosts of Empire in Central Asia, which talks about a road trip from Tashkent to Karakalpakstan, where millions of lives have been destroyed by the slow drying up of the sea. It is the story of an American travelling to a strange land, and of the people he meets on his way: Rustam, his translator, a lovely 24-year-old who picked up his colorful English in California, Oleg and Natasha, his hosts in Tashkent, and a string of foreign aid workers.

    This is a quick look at life in Uzbekistan, made of friendliness and warmth, but also its darker side of society. In Samarkand, Mr Bissell admires the architectural wonders, while on his way to Bukhara he gets a taste of police methods when suspected of drug dealing. In Ferghana, he attends a mountain funeral(葬礼)followed by a strange drinking party. And in Karakalpakstan, he is saddened by the dust storms, diseases and fishing boats stuck miles from the sea.

    Mr Bissell skillfully organizes historical insights and cultural references, making his tale a well-rounded picture of Uzbekistan, seen from Western eyes. His judgment and references are decidedly American, as well as his delicate stomach. As the author explains, this is neither a travel nor a history book, or even a piece of reportage. Whatever it is, the result is a fine and vivid description of the purest of Central Asian traditions.

On account of the government shutdown, many of the city's best attractions, such as the national museums, are closed. It may affect your social plans. That's especially true if you have out-of-town visitors coming to the District. Don't worry! For every closed museum, we've offered up a suitable substitute that is privately run, thus not subject to the shutdown. Here's where you can go instead.

Anacostia Community Museum and the National Museum of African American History and Culture

Alternatives: Banneker-Douglass Museum or Alexandria Black History Museum

The National Museum of African American History and Culture is one of the hottest draws on the National Mall, with free tickets taken weeks in advance. Its sister museum, the Anacostia Community (社区) Museum, takes a community-focused look at African American history. So does the Banneker- Douglass Museum in Annapolis, which traces (追溯) the African American experience in Maryland, and the Alexandria Black History Museum, where exhibitions honor local activists and explore the influence of slavery in the area. And unlike the African American Museum, neither requires you to plan ahead.

Hirschhorn Museum and Sculpture Garden

Alternative: Glenstone

Wandering through the galleries at Glenstone, you'll come across some of the biggest names in 20th century art — Jackson Pollock, Jean-Michel Basquiat and Robert Rauschenberg. Glenstone sits on a 230-acre estate (土地) that doubles as an outdoor sculpture garden. Free tickets for Glenstone are often reserved weeks in advance, but 72 free tickets are available every day for anyone who takes a Montgomery County Ride-On Bus from Rockville Metro Station to the museum.

National Museum of African Art

Alternative: The African Art Museum of Maryland

Masks, musical instruments and jewelry can be found in Fulton, where the African Art Museum of Maryland houses a collection of traditional and contemporary African artworks and objects. And the best part, for visitors on a budget? Admission is free.
