ID systems are used as a means for people to prove their identity, as a means of access control, or for many other situations. ID cards also contain a lot more information than simply the name of the holder. All ID cards contain information that is relevant to the institution that released them, so there is no single model that applies to all ID cards.

    Different institutions have different rules when it comes to ID cards, and ID cards used by students, in universities, will not have the same security features as those used in the military, for example. The more important the institution is, the more important the security is, and the more security features will be used to prevent duplication(复制) of an ID card.

    Anyone with a printer that can print ID cards can duplicate in ID card, if it does not have any security measures. There have been lots of cases, especially in low security institutions, where ID cards have been duplicated and this was not noticed, since the person holding the card usually flashed it when it was requested, and that was not enough to notice that it is a fake.

    That may not be extremely important when it is simply a case of a student trying to enter the campus of another university, but it can be of vital importance if it happens in a military institution. Checks in military institutions are much stricter and the personnel checking the card are always trained to spot fakes in a short amount of time.

    Some may think that creating an ID card is extremely difficult, but it is not. All it takes is a special printer that can print ID cards, a model and a photo ID. The fact that such printers can be freely ordered online has raised security issues with lots of companies and institutions, and most have decided to either create their own ID cards, or simply use more advanced security features that regular home-users do not have access to. This includes magnetic stripes(磁条), chips, barcodes(条形码),and other methods. This does increase the cost of the card per person, so the total cost of the cards increases based on the number of employees the company has, but it also reduces security risks to a minimum.

    So ID systems, as basic as they seem, are an excellent security measure for any institution. To ensure that the IDs look good and function properly, the company that handles the card printing services should be top-class. Trying to save some money by choosing a cheaper provider is not really wise. While some companies offer bonuses for large orders, if the quality provided is not of the highest standard, it is not worth it.

    I still remember that summer before college.There were plans and ideas about what my college experience was going to be like, but none of them worked out as planned.{#blank#}1{#/blank#}.

    Use the mental health services available to you.

    That first night at college was memorable. There was scare and homesickness. Missing things from home wasn't the only reason why I felt down. The academic pressure to succeed and the social pressure to fit in are too much for some people, which don't just happen in the freshman year.{#blank#}2{#/blank#} Close friends always guided me, which was important because talking helps—even if it's just with a friend. Don't be afraid to take that extra help.

    You're there to get a degree, but a little fun won't hurt.

    As time goes by, I'm not going to remember the grades I got on papers or the late nights spent studying. Instead, lifelong memories will include playing video games with my roommate at 3:00 am, or late-night runs with my friends after a night out. Apart from doing well inside the classroom, there are also internships(实习期) and other pressures. Employers might weigh internships more heavily than your GPA.{#blank#}5{#/blank#}.

    In business, there is a speed difference: It's the difference between how important firm leaders say speed is to their competitive strategy and how fast the company actually moves. The difference is important regardless of industry and company size. {#blank#}1{#/blank#}

    In our study of 343 businesses, the companies that choose to go, go, go to try to gain an edge ended up with lower sales and operating incomes than those that paused at key moments to make sure they were on the right track. What's more, the firms that “slowed down to speed up “improved their top and bottom lines, averaging 40% higher sales and 52% higher operating incomes over a three-year period.

    {#blank#}2{#/blank#} They thought differently about what "slower" and "faster" mean. Firms sometimes fail to understand the difference between operation speed (moving quickly )and strategic speed (reducing the time it takes to deliver value ).Simply increasing the speed of production, for example ,may be one way to try to reduce the speed difference .But that often leads to reduced value over time, in the form of lower-quality products and services.

    In our study, higher-performing companies with strategic speed always made changes when necessary. They became more open to ideas and discussion. {#blank#}3{#/blank#} And they allowed time to look back and learn. By contrast, performance suffered at firms that moved fast all the time, paid too much attention to improving efficiency, stuck to tested methods, didn't develop team spirit among their employees, and had little time thinking about changes.

    Strategic speed serves as a kind of leadership. {#blank#}4{#/blank#} That kind of strategy must come from the top.

A. How did they disobey the laws of business physics, taking more time than competitors yet performing better?

B. Teams that regularly take time to get things right, rather than plough ahead full bore, are more successful in meeting their business goals.

C. More haste, less speed, which in the study proves wrong.

D. Companies fearful of losing their competitive advantage spend much time and money looking for ways to pick up the speed.

E. They valued efficiency rather than consideration.

F. They encouraged new ways of thinking.

    {#blank#}1{#/blank#} According to a new survey by the National Sleep Foundation, 51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights, even though they have to get up early. Last year the Foundation reported that nearly 60% of 7- to 12-year-olds said they felt tired during the day, and 15% said they had fallen asleep at school.

    {#blank#}2{#/blank#} Babies need a lot of rest: most of them sleep about 18 hours a day! Adults need about eight hours. For most school-age children, ten hours is ideal. But the new National Sleep Foundation survey found that 35% of 10- to 12-year-olds get only seven or eight hours. And guess what almost half of the surveyed kids said they do before bedtime? Watch TV.

    "More children are going to bed with TVs on, and there are more opportunities to stay awake, with more homework, the Internet and the phone," says Dr. Mary Carskadon, a sleep researcher at Brown University Medical School. She says these activities at bedtime can get kids all excited and make it hard for them to calm down and sleep. {#blank#}3{#/blank#} Changing levels of body chemicals called hormones not only make teenagers' bodies develop adult characteristics, but also make it hard for teenagers to fall asleep before 11 pm.

    Because sleepiness is such a problem for teenagers, some school districts have decided to start high school classes later than they used to. {#blank#}4{#/blank#} Students parents and teachers are pleased with the results.

A. How much sleep you need depends a lot on your age.

B. Other experts say part of the problem is chemical.

C. Getting less sleep has become a bad habit for most American kids.

D. what homework waiting for kids might always affects them sleep well every night.

E. Raising the minimum sleep is identified as a key way to help solve the problem.

F. Three years ago, schools in Edina, Minnesota, changed the start time from 7:25 am to 8:30 am.

    There was a man named Ken Nwadike who wanted desperately to run this year's Boston Marathon. But the Boston Marathon is different from most marathons: you have to qualify in order to enter it. Namely, you have to have completed your previous marathon in a certain amount of time, depending on your age category.

    Well, the man in question was 23 seconds short of the qualifying time he needed in order to enter the marathon. He had a number of options. He could get angry. He could blame someone. He could get depressed. Any of them could easily have led to his turning tail(逃走) and going home, angry or depressed.

    Instead, Ken Nwadike attended the Boston Marathon in his own way. He made a " Free Hugs" sign, and with that had a camera on a tripod (三脚架), he gave out hugs and smiles to the runners that passed him by, his way of encouraging and supporting them. From that humble beginning, Ken began his widely acclaimed Free Hugs Campaign, which states its purpose as follows: "continuing the movement of Dr. Martin Luther King, Jr., the mission of the Free Hugs Project is to spread love, inspire change and raise awareness of social issues." His campaign, which quickly became a huge success, got the widespread compliments.

When things go wrong in our lives, as they do from time to time — sometimes seemingly all the time — we have a choice. We need to take a deep breath, judge the situation, and find a positive direction in which we should go. Whether it's something relatively small, like missing a marathon, or large, like losing a loved one, let Ken's story inspire you to take that breath, re-orient(重新调整)yourself, and move on to doing something worthwhile with the experience.
