Why Do We Get Angry?

    Anger seems simple when we are feeling it, but the causes of anger are various. Knowing these causes can make us examine our behavior, and correct bad habits. The main reasons we get angry are triggering（触发）events, personality traits（特征）, and our assessment of situations. {#blank#}1{#/blank#}

    Triggering events for anger are so many that to describe them all would take hundreds of pages. However, here are some examples: being cut off in traffic, a deadline approaching, experiencing physical pain, and much more.{#blank#}2{#/blank#} The reason why someone is triggered by something and others are not is often due to one's personal history and psychological traits.

    Each person, no matter who they are, has psychological imbalances. People who have personality traits that connect with competitiveness and low upset tolerance are much more likely to get angry. {#blank#}3{#/blank#} Also, sometimes pre-anger does not have to do with a lasting condition, but rather a temporary state before a triggering event has occurred.

    {#blank#}4{#/blank#}Sometimes even routine occurrences become sources of pre-anger, or anger itself. Sometimes ignorance and negative (消极的) outlooks on situations can create anger.

    {#blank#}5{#/blank#}However, anger can easily turn violent, and it is best to know the reasons for anger to appear in order to prevent its presence. With these main reasons in mind, we can evaluate our level of anger throughout the day and prevent cases of outbursts by comprehending the reasons for our feelings.

A. Our attitude and viewpoint on situations can create anger within us as well.

B. But some types of situations can help us to get rid of the occurrence of anger.

C. Anger is rarely looked upon as a beneficial character trait, and is usually advised to reduce it.

D. Anger is a particularly strong feeling and maybe people think that they have reasons to feel angry.

E. Having these personality traits implies the pre-anger state, where anger is in the background of your mind.

F. Understanding these reasons will control our own anger if we are willing to evaluate ourselves with a critical eye.

G. Not everyone acts the same in response to events, and that is why what triggers one person may or may not trigger another.

    Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy, as there's no need for a lot of scientific terms or expensive lab equipment. {#blank#}1{#/blank#}.

    Give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. {#blank#}2{#/blank#}, children can give more logical, complete and creative answers.

    Watch your language. Once you have a child involved in a science discussion, don t jump in with "That's right" or "Very good". {#blank#}3{#/blank#}. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying "That's interesting or "I have never thought of it that way before", or coming up with more questions or ideas. Never force a child to think. {#blank#}4{#/blank#}, as children are always thinking, without your telling them to.

    What's more, giving them freedom to think can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target for your disagreement.

    {#blank#}5{#/blank#} Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass (放大镜) and they'll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸发), set a pot of water to boil and let them watch the water level drop.
