The most exciting storms are the ones with flashes of lightning.Unfortunately,those are scarce,unless you are near the Catatumbo River in Northwestern Venezuela.Here,nature's grandest sound and light show is often seen, because it happens about 160 nights a year.And it lasts for as long as 10 hours at a time.And unlike other lightning storms that cause just one or two flashes,this one is with as many as 280 per hour.It is the highest in the world. Besides,each one of them is so powerful that each can power every light bulb in South America.Not surprisingly,they can be seen for almost 250 miles.Fishermen and sailors often use them to guide them across the waters during dark nights.

    What's even more surprising is that the lightning has been happening above the same spot where the Catatumbo River meets Lake Maracaibo for thousands of years.The best part is that the show is different every night.That's because the color of the lightning changes,depending on the amount of water in the atmosphere.On dry nights,the lightning appears white.When the air is not dry,it helps split up the bright light into red,orange and even purple.

    Strangely enough,though this has been going on for centuries,scientists have still not been able to figure out the cause of this phenomenon.Some say that the storms are the result of the interaction of the area's unusual topography（地貌）,wind and heat.Others,however,believe that the storms are caused by a kind of gas in the area.The locals simply think that it is the "spirit of Catatumbo" that lights up the night sky.

    A layover (临时滞留) or flight delay can be extremely fun in these international airports.

Munich Airport, Germany

    As we know, everyone can make mistakes, but don't worry about it. The following is what we should do when we make mistakes.

    Just admit (承认)it. Don't think that our mistakes are caused by others.{#blank#}1{#/blank#} Don't blame other people, and don't cheat ourselves, either.

    {#blank#}2{#/blank#}. In order to stop the problem from getting worse, we should act quickly to solve it. If we don't act and deal with the problem quickly, it'll only make us feel more stressed. Also it is necessary to make a plan of action and correct the mistake according to it.{#blank#}3{#/blank#}.

    {#blank#}4{#/blank#} . Those who have made the most mistakes can get an A, for they are the ones who have learned the most. The more we learn from our mistakes, the cleverer we are.

    {#blank#}5{#/blank#}. What caused us to make the mistake? How can we avoid making the same mistake in the future? When we act with a method to get a good result, do it that way next time. If we don't, we should stop, think about it, change it and try again.

A. Think about what we can learn from our mistakes.

B. Be brave and face the fact that we have made the mistakes.

C. So decide quickly and act.

D. Realize that making mistakes is the best way to learn.

E. Solve it at once.

F. Don't be afraid of failure.

G. So be away from stress.

    Teachers in some secondary schools in Britain are worried that their job may become impossible shortly unless something can be done to restore discipline in the classrooms. In the problem schools, mostly in large cities, a small minority of teenage pupils disturb lesson to such an extent that the teacher can no longer teach their classes effectively.

    Some people consider that the permissive (随意) nature of modern society is responsible for such kind of behavior. Small children who are continuously encouraged to express themselves without reservation are naturally unwilling to accept school discipline when they grow older. Furthermore, modern teaching techniques) which appear to stress personal enjoyment at the expense of serious study work, might be teaching the child to put his own interests before his duties to the community in which he lives.

    Perhaps the problem can be solved by improving facilities for the moral guidance of these difficult children or by better cooperation between the schools and the parents—for the parents may be mainly responsible for the bad behavior of their youngsters. Violence at home, violence and crime on TV make some children turn violence themselves.

    But some of the teachers believe that there ought to be a return to more “old fashioned” methods. At present, in some school teachers are even not allowed to punish a child who does something bad and wrong. Physical punishment is not permitted now. People are too soft on children these days. It seems that children can do whatever they like at school while the teachers can't do anything to punish them. I don't know why the schools authority abandoned some of the effective punishments that worked well. Things like that didn't happen when we were at school because the teachers kept those problem students under control by using a stick.

    While it is impossible to live completely free of stress, it is possible to prevent stress as well as reduce its effect when it can't be avoided. {#blank#}1{#/blank#}

    Try physical activity.

    {#blank#}2{#/blank#}Running, walking, playing tennis, and working in your garden are just some of the activities you might try.

    Make time for yourself

    Schedule time for both work and entertainment. Don't forget, play can be just as important to your overall well-being as work. {#blank#}3{#/blank#} Go window-shopping or work on a hobby. Allow yourself at least a half hour each day to do something you enjoy.

    Take care of yourself

    {#blank#}4{#/blank#}If you easily get angry and can't sleep well enough, or if you're not eating properly, it will be more likely that you will fall into stressful situations. If stress repeatedly keeps you from sleeping, you should consult a doctor.

Stress can result from disorganization and a feeling that "there's so much to do, and not enough time". Trying to take care of everything at once can be too much for you and as a result, you may not achieve anything. Instead, make a list of everything you have to do, then do one thing at a time, checking off each task as it is completed. Set out to do the most important task first.

A. Do whatever you like and want to do.

B. You should make every effort to eat well and get enough rest.

C. Make a list of things to do.

D. When you are nervous, angry or upset, try releasing the pressure through exercise or physical activity.

E. You need a break from your daily routine to just relax and have fun.

F. You could smile to yourself in front of a mirror every day.

G. The following are suggestions for ways to deal with stress.

What Is a Superiority Complex?

A superiority complex is a behavior that suggests a person believes they are somehow superior to others. People with this complex often have overstated opinions of themselves. They may believe their abilities and achievements are better than those of others. However, the complex is believed to be a defense system for feelings of inadequacy that we all struggle with.

It is unclear why a person develops a superiority complex. Multiple incidents may be the root cause. For example, it may be the result of many failures. A person tries to complete a specific goal or achieve a desired outcome, but they don't succeed. They learn to handle the anxiety and stress of the failure by pretending to be above it. If they feel protected from their failures in this way, they may repeat this behavior in the future.

These behaviors can begin at an early age. When a child is learning to cope with challenges, they may learn to control feelings of inadequacy or fear. A superiority complex may develop. Likewise, it may also happen later in life. As teens and adults, a person has many opportunities to try new things among new people. If these situations are not successfully coped with, a person may develop a superiority complex to overcome feeling isolated.

People with a superiority complex are unlikely to be a threat to anyone's physical health. However, the continuous lies and overstatements can become annoying to others and may negatively affect relationships. It can push away other people in your life and shrink your social circle. If you are in a relationship with a person who you think has the issue, encourage the person to seek help. For example, never hesitate to reach out to mental health professionals. They can find healthier ways to deal with hidden feelings.
