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.

    There is an English saying: “{#blank#}1{#/blank#} Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body{#blank#}2{#/blank#}

    Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise{#blank#}3{#/blank#}If laughter exercises the body, it must be beneficial.

    Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated the pain for the longest time was the group which listened to a funny program.{#blank#}4{#/blank#}

    {#blank#}5{#/blank#}They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

A. Laughter can change one's life.

B. As a result of these discoveries, some doctors in the United States now hold laughter clinics in which they help to improve their patients' condition by encouraging them to laugh.

C. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain.

D. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach and even the feet.

E. Although laughter helps cure the disease, doctors still can not put this theory into clinic practice.

F. Laughter is the best medicine.

G. They have found that laughter really can improve people's health.

The Lost Rules of Etiquette

    Etiquette, or good manners, used to be the glue that held society together{#blank#}1{#/blank#}Sadly, these days it has mostly gone by the wayside. This list is several best rules of etiquette that have now disappeared.

Opening the Door

    In days gone by, a gentleman would always open doors for ladies{#blank#}2{#/blank#}This has now almost entirely disappeared-- and it is pot entirely the fault of the men. I have seen women laugh at men for opening a door for them. They seem to be confusing manners with chauvinism(大男子主义)．

Writing Thank-You Notes

    In days gone by, whenever a person received a gift, they would write a thank-you note as soon as possible{#blank#}3{#/blank#}Parents would sit children down after a birthday or Christmas and coach them in their first thank-you note. It is a shame that gift giving has now become a virtual obligation and the idea of a thank-you note would be laughed at.
{#blank#}4{#/blank#}
         We seem to have completely lost the concept of correct timing when it comes to parties these days{#blank#}5{#/blank#} After all, a party normally has a guest of honor-this is usually the oldest woman present. It was considered extremely rude in the past to leave a party before the guest of honor-and once the guest of honor left, it was a signal to all that they should begin their own preparations to leave.

A. Arriving on Time.

B. Leaving at the Right Time.

C. People leave with various excuses.

D. It enabled people to get on well with each other.

E. This rule was true even if the giver was a relative.

F. It could be the lady they were driving, or a stranger.

G. We've thrown away the concept of a guest of honor at will.

    The most successful people all have certain habits in their daily routines. These habits help contribute to their success. Forming a new good habit can be a struggle, but it is well worth the effort. {#blank#}1{#/blank#}

    If you travel, you will leave a carbon footprint in your wake. You can't help it. But eco-friendly travel practices can lighten the harm on Mother Earth. Green travel is not a passing trend but a lifestyle choice. {#blank#}1{#/blank#}.

    Choosing a green destination

    No destination is a Green Giant. {#blank#}2{#/blank#}. However, some countries and cities show a deep commitment to Earth-friendly policies and practices. When researching a vacation spot, look for places that naturally embrace the green lifestyle.

    Choosing green transportation

    What makes Mother Earth proud? Seeing you use your own power to get around. Many adventure tour operators arrange cycling, hiking and walking holidays. {#blank#}3{#/blank#}. The greenest rides typically run on electric power. Switzerland is taking the lead with its hybrid buses and trains powered by hydroelectricity; Japan is running close behind.

    Choosing a green hotel

    Once you are at your destination, if you can get the hotel right, you can make the greatest impact. {#blank#}4{#/blank#}. Look for a fact sheet online, or call the front desk. You can also search for hotels approved by respected certification programs, such as Green Key and the Global Sustainable Tourism Council.

    {#blank#}5{#/blank#}.

    The Earth-friendly choices are numerous: You can sail, bike, kayak, bike, swim, bird-watch and play I-spy-a-monkey in a tree. Visit a local food market, and don't forget to bring a reusable bag for purchases. You can also lend a hand during your holiday. The green movement has changed from how to preserve and protect to how to use less and do good when you're there.

A. Choosing green travel

B. Choosing green activities

C. Next in line are trains and buses

D. They all make environmental missteps

E. Most major chains operate in-house green program

F. If you plan to drive, consider a fuel-efficient vehicle

G. Follow the tips and watch your footprints turn greener

Today, technological advances are rapidly making it possible to automate much of the work currently carried out by humans. This applies to both blue-collar jobs through robotics and the Internet of things, and white-collar work through artificial intelligence, the wide applicability of these technologies has led to broad concern about the destruction of jobs. Indeed, according to a 2014 Oxford study, 47% of jobs in the US could be replaced. By automated processes in the next two decades.  

Of course. As many have noted, while technology has always removed the need for some types of jobs, it also creates new ones. Technology is a set of tools that we use in different ways to increase efficiency. The Industrial Revolution destroyed some jobs but created many more. It also increased the total wealth of society and began to create a middle class who could enjoy health, education and other benefits that previously had been available only to the wealthiest. It can be challenging to predict the kinds of jobs that this new revolution will create and in what quantities, which makes the situation seem worse than it actually is. But nine of the top ten most in-demand jobs of 2012 didn't exist in 2003, suggesting that this latest revolution is creating new employment opportunities.

For many, this picture is overly optimistic. The new jobs require a completely different skills set —you can't turn an assembly plant worker into a data scientist overnight. Others are concerned that we are facing a permanent reduction in the need for human labor. Science fiction has long imagined a future where we no longer have to work and can spend our time on more noble pursuits. Could it be that we are reaching that inflection point in human history, if we are? Neither our social norms nor our economic systems are ready for it. Today, self-worth is inherently tied up with jobs，professions，careers and trades.
