Many of us invest valuable time，energy and money planning our vacations. We do this because we know for sure that going on vacations must be good for us. Research proves this feeling without a doubt. Vacations help us perform better at work, improve our sleep quality and cushion us against depression.

    Yet, despite these benefits, many of us return home with a feeling that our last vacation was OK - but not great. In order to change this, some mistakes should be avoided. A classic one for vacation planners is attempting to maximize value for money by planning trips that have too many components (组成部分)• Perhaps you're planning a trip to Europe, seven cities in 10 days，and you realize it will cost only a little more to add two more destinations to the list Sounds fine in theory, but hopping from one place to the next hardly gives an opportunity to experience what psychologists call mindfulness - time to take in our new surroundings, time to be present and absorb our travel experiences. Another mistake is that we worry too much about strategic issues such as how to find a good flight deal，how to get from A to B，or which destinations to add or subtract from our journey. These issues may seem important, but our psychological state of mind is far more important.

    Actually, vacation happiness is based on the following top rules. First, choose your travel companions wisely, because nothing contributes more significantly to a trip than the right companions. Second，don't spend your vacation time in a place where everything is too expensive so as to maintain a positive mood. Third, shop wisely, for meaningful experiences provide more long-term happiness than physical possessions.

Easy Ways to Keep Your Brain Sharp

    Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing.{#blank#}1{#/blank#}Read on for some techniques worth trying.

    ⒈{#blank#}2{#/blank#}

    People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study.{#blank#}3{#/blank#}Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

    ⒉ Go for a walk

    Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain.{#blank#}4{#/blank#}

    ⒊ Learn something new

    Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time.{#blank#}5{#/blank#}or go dancing with your friends.

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

D. So take a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

    There is a woman named Tao Porchon-Lynch. She was born in India in 1918. So, if you do the math, she's 99. And at the age of 99, she has been recognized as the oldest yoga teacher in the world. She has been teaching yoga in a gym in her hometown, full-time, since 1967.

    But that's not all she's done. She has also been a model, actress and dancer. She became a model after she graduated from high school. She acted in more than ten fields. She won a lot of medals as a dancer in many competitions. She once said, “If you try your best and never give up, nothing is impossible.” And she is a firm believer in positive thinking. She dreams the impossible dreams, and she is also well known as a thinker.

    Tao Porchon-Lynch is not the person who talks the talk; she is the person who walks the walk. When she makes up her mind to do something, she takes action to do it without delay. At the age of 85, she learned how to dance and even won several dance competitions. She offers this piece of advice to others, “Don't put off till tomorrow what you can do today. Don't delay. Tomorrow never comes.”

    So, what about retirement? At 98, she is well past the age when many people make retirement plans. Retiring, it turns out, is not Tao's style. “A little girl, who is only 6 years old and is now learning yoga with me, once asked me, ‘Dear granny, what are you going to do when you retire?'” Tao Porchon-Lynch told the little girl that she had no plans to retire but instead would continue to teach yoga and dance her way to next planet.

    Some years ago industries had more freedom than they now, and they did not need to be as careful as they must today. They did not need to worry a lot about the safety of the new products that they developed. They took little notice of the health and safety of the people who worked for them. Often new products were dangerous for the people who used them and conditions in the work place had very bad effects on the health of the workers.

    Of course, sometimes there were real disasters which attracted the attention of governments and which showed the need for changes. Also scientists who were doing research into the health of workers sometimes produced information which governments could not ignore. At such times, there were inquiries into the causes of the disasters or the problems. New safety rules were often introduced as a result of these inquiries; however, the new rules came too late to protect the people who died or who became seriously ill.

    Today many governments have special departments which protect customers and workers. In the U. S, for example, there is a department which tests new airplanes and gives warnings about possible problems. It also makes the rules that aircraft producers must follow. Another department controls the foods and drugs that companies sell. A third department looks at the places where people work, and then reports any companies that are breaking the laws which protect the health and safety of workers. Of course, new government departments and new laws cannot prevent every accident or illness, but they are having some good results. Our work places are safer and cleaner than before. The planes and cars which we use for travel are better. Producers are thinking more about the safety and health of the people who buy and use their products.

    Patrick and Rachel Hugens have biked around the world. The Hugenses, who live in Boise when not on their bikes, are 25 months into their latest round-the-world adventure, scheduled to end in March. They've visited 36 countries on this tour, touching Europe, Africa, Asia and South America. “Traveling by bike is the greatest freedom," Rachel said via email. “You can see people's daily lives and can communicate with them.”

    Rachel warns, “Cycle touring can become addictive.” Bike tourism is on the rise in the United States and around the world, according to the Adventure Cycling Association. The U. S. Bicycle Route System has grown 66 percent in the past two years and now has a presence in 24 states, including Idaho, and the District of Columbia.

    Dennis Swift，secretary of the Southwest Idaho Mountain Biking Association, rode across the U.S. last year- from Seattle to Salem, Mass. Six people started the tour and three finished, riding 52 out of 56 days. They averaged about 60 miles per riding day. Swift also rode through the Basque Country with a group of Boise cyclists last year. He's planning to participate in a Virginia bike tour this year. “When you get older, your health is most important,” he said. “My mom had Alzheimer's disease. They say what's good for health is good for the brain, so riding is one thing to be first in my life.”

    This is the third time that the couple have quit their jobs to tour. Rachel is a nurse; Patrick is an architect. Both regained their former jobs when they returned home in 2000 and 2007. They're uncertain what will happen this time. They've given themselves a chance to save extra money by going to work by bike and avoiding some bills that are basic for most (cell phones, cable TV).“Traveling changes your view of money and what it can do for you,” Rachel said. “We've met some cyclists traveling long term. They have many reasons to spend wisely.”

    “The fellow cyclists we meet mostly come from Britain, Germany, Spain, Holland, Australia or New Zealand," Rachel said, “It is so nice to see that people all over the world are friendly and welcoming.”

    Earth is home to around 7, 000 languages, around half of which are expected to disappear by 2100.

    Languages disappear for many reasons. Sometimes younger generations stop learning a language because parents want children to fit in.{#blank#}1{#/blank#} Native American children of the late﹣19th century were required to attend boarding schools where educators forbade them from speaking their native languages.

    The United Nations ranks endangered languages according to their risk level. For example, a "critically endangered" language is one that even grandparents don't speak often. New York's Onondaga language is an example with only 50 speakers left. An "extinct" language has no speakers. It is gone forever. Alaska's Eyak language is one example.{#blank#}2{#/blank#}

    {#blank#}3{#/blank#} In the same way, different languages contribute to cultural diversity. Saving these languages benefits our understanding of other cultures. Languages can show how a society looks at the world and what it values. A language may describe something in a way that is funny, too. In Welsh, it rains not cats and dogs, but old wives and walking sticks.

    The Endangered Language Alliance wants to save languages from disappearing.{#blank#}4{#/blank#} However, its efforts are limited. If an endangered language is going to make a real comeback, it'll probably get its start in schools. For nearly 100 years, public schools in Hawaii did not teach the Hawaiian language. Now students can keep learning in Hawaiian from elementary schools to college and beyond.

    {#blank#}5{#/blank#} At least one did. In 1881, a Jewish linguist named Eliezer Ben﹣Yehuda brought the 3,000-year-old language Hebrew back to life. Today it is one of the official languages of the country of Israel, with more than 4million speakers.

A. The last person who spoke it died in 2008.

B. Why should we save endangered languages.

C. Various animals and plants benefit our environment.

D. With just 5 speakers left, it is absolutely endangered.

E. Can a language with zero native speakers come back to life.

F. Sometimes societies force minorities to give up their language.

G. The non-profit group finds native speakers and records their stories.
