For many people, history classes are seen as no more than requirements for getting degrees in chemistry, biology, business, marketing, etc. {#blank#}1{#/blank#}． Below are a few reasons why it's vital that today's people continue to learn about the past.

    Understanding where people come from plays a key role in understanding who they are.{#blank#}2{#/blank#} For this reason, it's extremely important to learn history in order to understand why people are the way that they are.   

    Through history classes, you can experience a shift (改革) in the way you think. {#blank#}3{#/blank#}It's important to develop minds to be able to consider problems from different angles. Finally, this shift can improve your ability to analyze and understand situations, to make educated decisions and to learn how to weigh the consequences related to each choice before you.

    {#blank#}4{#/blank#}The idea that history repeats itself is rooted in truth. From wars to fashion to political trends, historians are often able to make predictions about the future based upon the past. By having a deep understanding of what happened in the past, today's people can better prepare for brighter futures by making the right decisions—instead of repeating old mistakes.

    Many people may not believe that a degree in history can lead to a well-paid job. In fact, students who graduate with degrees in history can become lawyers, business owners, think tank members, educators, leaders in historical organizations writers and so on. {#blank#}5{#/blank#}.

    We all believe we listen well and yet many times we feel others are not listening to us. However, listening goes in both directions—you may believe you are listening well, but how often have you completely forgotten what was said to you? {#blank#}1{#/blank#}

Make eye contact.

    {#blank#}2{#/blank#} when People talk, they put out visual clues that add to the conversation and meaning of their words.

Stop talking.

    You can't listen, talk and at the same time completely receive the meaning of the other person's words. {#blank#}3{#/blank#}

React without words.

    Let the other person know you are listening through physical reactions, such as head nods, smiles, frowns and eye movement.{#blank#}4{#/blank#}

Concentrate.

    Concentrate on what the other person is saying. Clear your mind of other thoughts and emotions and focus on the conversation at hand. Be in the moment of that conversation, and don't think about what you want to say back.

    Behave as an effective listener. The more you continue to behave as a listener, the more you will be an effective listener.

    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.

Taping and bracing ankles

    Ankle sprains(踝关节扭伤) are the most common sports-related injuries in the United States. If there was an easy way of decreasing the number and severity of these injuries, that would be great. For this very reason, the practice of taping and bracing ankles was introduced decades ago.

    How, then, do taped or braced ankles decrease the incidence and severity of sprains in athletes? One explanation for how it works comes from a study which found that taped athletes had improved proprioception(本体感受), which is the body's ability to know how fast the ankle and foot are moving and if they are starting to roll over or not. When they were compared, the athletes with taped ankles had better proprioception both before and after exercise compared with athletes using no tape. The tape's traction(拉力)or pressure on the skin of the foot and ankle helped improve sensitivity and proprioception, resulting in fewer ankle sprains.

    Another common concern often expressed by the public is that lengthened practice of taping or bracing ankles results in weak ankles that then tend to get injured more easily; this would be a strong case against taping or bracing ankles. However, a scientific study looked at the effects of consistent ankle brace use on the peroneus longus muscle. It is an important stabilizer(稳定装置)of the ankle, particularly against inversion, the most common type of ankle injury. This study showed that the peroneus longus muscle's ability to do its job was not changed by the long-term wearing of an ankle brace.

    Many studies have been completed to compare taping ankles and bracing ankles to try to determine which one is better. Most have shown that braces are slightly more effective than tape, but that both are better than no support at all. One study found that simply wearing high-top sneakers instead of low-tops prevented some ankle injuries and that high-tops plus tape had more than 50% fewer injuries than low-tops plus tape.

    So whether it's on the field or on the court, the tape or brace is an important piece of athletic equipment just like your helmet or mouth guard.
