      The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap(间隙)with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

        Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied(暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

        Other cultures may use silence in other ways, particularly when dealing with conflicts among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions are given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing(治愈) value of silence can use this understanding to assist in the care of patients from their own and from other cultures.

    What is success? I am not going to try to explain success. I think a precise meaning is impossible! Is it winning a Gold Medal at the Olympic Games or winning Wimbledon, or being awarded a Nobel Prize? What else? I believe personal success could be anything at all- it does not have to involve public recognition. Who is more successful? A millionaire who is unhappy, or an unnoticed person, who has led a simple, quiet, sincere and happy life? The simplest definition of success, I think, is “to set out to do something and to succeed in doing it.

    The first step on the road to success starts with belief. Believe you can succeed and you will. Achieving success in whatever endeavor(努力)you choose may be the goal of life; because it gives you freedom from worry. Could that be?

    Success means different things to every one of us. Some people believe it is measured in financial term; others believe it is helping others rather than helping themselves. However, most people are motivated to a great extend by public recognition. How many people are really happy? How many people are really doing what they want to with their lives? Incidentally, to imagine makes us different from animals.

    Most important of all, I believe success is a matter of personal growth. If every day you are developing or growing just a millimeter, I believe one is successful. Just being a slightly better person each day for me is success. I've got a very long way to go them!

    Finally, always remember success is a process and is not simply a matter of arriving at a destination. It's the journey that really matters. Success is what you become in the often very difficult and dangerous journey down the river of life.

    Football, to me, is more than just a game. I have probably learned more than valuable lessons from it than from school.

    When I joined the team freshman year, I didn't realize what I was getting into. Even though I had been playing since fourth grade and knew it was hard work, nothing would prepare me for the effort I would put into football that year. We worked all summer in the weight room and ran on the track to get in physical and mental shape before the season.

    See, football is more of a mental sport than anything else, so running on the track wasn't only about getting in shape. We would push our minds by running as hard as we could even if we felt like we were going to pass out. At the beginning, I was immature（幼稚的）and only thought of myself, sometimes even giving up when I was tired or hurting. Then after the third game I had a season-ending injury. Imagine working all summer and then only being able to play three games! I needed an operation on my arm and at least five months to recover.

    After freshman year I decided that I would always give my best effort. Playing football in the college has taught me so much more than just what my tasks are on a particular play or how to block. I have learned to think about others first, and realized how important working hard is. Being with all my friends, even sweating and bleeding with them, really made us unite as a group of hard-working young men, who will succeed in life.

    Stained glass (彩色玻璃) artists create different designs by making cuts on the glass to “score” it and then breaking off the pattern that they want to use in the finished product. The most difficult cut in stained glass is called an inside cut. Basically, it's a curved (弯曲的) line where you throw away the part inside of the curve. The problem with inside cuts is that the edges of the curve tend to break off when the pieces of scored glass are broken apart.

    As the artist talked about inside cuts, he said, “The glass will break into pieces if you try to cut too much off at once. The best way to do an inside cut is to slice off smaller curves piece-by-piece. In fact, it's not just the best way to do it, but it's the only way to do it.”

    How many times do you try to make a big change and cut the entire piece at once? We convince ourselves that we can do this all the time. We'll commit to transforming our diet overnight or we get inspired to launch a business in a weekend or we finally get motivated to work out and push ourselves to the edge of burning out.

    Why not approach your goals and dreams like a stained glass artist? Starting by slicing a shallow curve and breaking a small piece off, you cut a slightly deeper curve and break that off until you have your full inside cut. By slowly cutting deeper and deeper curves, you prevent the glass from breaking as it changes shape.

    Of course, change isn't easy — no matter how you do it. Slow gains are boring, but if we keep making small improvements, then pretty soon we will end up with a beautiful masterpiece on our hands instead of a bunch of broken pieces.

Located at Europe's biggest water park, the Galaxy Erding in South Germany, the world's first VR water slide takes the exciting experience to a whole new level by offering thrill-seekers the choice of three attractive worlds — Space, Sky, or Snow. By simply wearing a headset, riders can slide through a magical alien world, follow beautiful butterflies around floating islands or put themselves in a white winter wonderland. To make the experience even more heart-stopping, the 160-meter-long ride that lasts about 35 seconds has two uphill tracks that provide a roller-coaster-like experience.

    While the tire slide, which has been successfully tested by almost 10,000 park goers since it opened in February 2018, is impressive, the technology behind it, developed by California startup Ballast is even more so. The specially-created waterproof headsets can be worn in water up to a few meters deep, without harming the delicate Samsung Galaxy S8 mobile devices that run the custom software for the VR experiences. The headsets also charge wirelessly (无线地), allowing park operators to swap out sets throughout the day.

    The biggest challenge the company faced, however, was providing a suitable VR experience for everyone. That's because unlike roller coasters, where the speed is fixed for all riders, water slide speeds vary depending on the weight of the person. To overcome the issue, Ballast fixed  smart sensors (传感器) in important areas along the slide to keep track of the rider's progress at  all times. The information, conveyed through the headset, allows the custom software to adjust his or her location within the virtual world accordingly, making for a smooth, seasickness free ride for all.

    Though Ballast is thrilled at Space Glider's success, the company has bigger ambitions. They want to create an experience where guests will be able to swim underwater surrounded by virtual dolphins, whales, and even sharks, without wearing the heavy headsets!

    Some people will do just about anything to save money. And I am one of them .Take my family's last vacation .It was my six-year-old son's winter break from school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline ,offered us $400 per person in credits to give up our seats and leave the next day .I had meeting in New York, So I had to get back . But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.

    The next day my husband and son were offered more credits to take an even later flight. Yes, I encouraged一okay, ordered-them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?

    Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is some-time thing few of us can afford to pass up.

    I've made living looking for the best deals and exposing (揭露) the worst tricks .I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in. I tell you this because there is no shame in getting your money's worth. I'm also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.
