Young people are particularly prone to (易于) risky listening habits. Around half of those between the ages of 12 and 35, or 1.1 billion people, are at risk due to "prolonged and excessive exposure to loud sounds, including music they listen to through personal audio devices." the UN health agency said.

Currently, about five percent of the global population, or some 375 million people, including 34 million children, suffer from disabling hearing loss, WHO considers a volume above 85 decibels (分贝) for eight hours or 100 decibels for 15 minutes as unsafe. WHO is calling for parental as well as automatic volume controls on audio devices to prevent dangerous use.

While some smartphones and other audio devices already offer some of these features, the UN would like to see a uniform standard used to help protect against disabling hearing loss. "Think of it like driving on a highway, but without a speedometer in your car or a speed limit," Shelly Chadha of the WHO told reporters in Geneva. "What we've proposed is that your smartphones come fitted with a speedometer, with a measurement system which tells you how much sound you're getting and tells you if you are going over the limit."

The workers and employees are anxious, seemingly because they might find themselves out of a job or they would say that they are unable to acquire any real satisfaction or interest in life. In fact, they live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.

Those higher up on the social ladder are no less anxious. Their lives are no less empty. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of submissiveness(顺从)and independence. From the moment on they are tested again and again by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one's fellow-competitor creates constant anxiety and stress, the very causes of unhappiness and illness.

Am I suggesting that we should return to the pre-industrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system from a bureaucratically managed industrialism in which maximal production and consumption are ends in themselves into a humanist industrialism in which man and full development of his potentialities are the aims of social arrangements. Production and consumption should serve as means to this end, and should be prevented from ruling man.

How to Concentrate on Studies

How to get your mind to concentrate on studies when there are all possible distractions (分心的事)? This is the biggest question that students face when it's exam time. Well, here are some tips that can help you with concentration.

It is always best to have a plan before studying. However, be realistic with your timetable and do not expect too much out of yourself.

If you study the same subject for 5 hours, you maybe get bored. So it is advised that you keep on changing your subjects so that you do not get bored. However, make sure you study at least 2 hours at each subject at a stretch (连续地).

Set up a study area

It is better to have a study room where you can concentrate properly without any distractions. If that is not possible, you can set up a study table in a separate corner in your home. Make sure you study at this place so that you can help your mind focus.

Your mind will be at its sharpest only if you let it rest for enough time. Sleep for at least 6～8 hours depending upon your individual requirements. And reward yourself some free time after studies.

A. Take interest

B. Get enough rest

C. Introduce variety

D. Plan your timetable

Castles played an important role after the fall of the Roman Empire. When a king gave land to nobles, the nobles promised in return to serve the king and provide him with soldiers. Nobles built castles on the lands given to them. But some nobles simply claimed land as their own and built a castle on it.That was asking for trouble. There were many power struggles between nobles and kings, and among the nobles themselves.

Many stone castles were surrounded by a wide ditch called a moat (护城河). Some moats were filled with water, but many were not. The only way into the castle was across a wooden drawbridge over the moat. If enemies attacked, the defenders raised the bridge. Then they lowered a heavy iron-and-wood barrier called a portcullis to block the entrance to the castle.

A well-built castle was a pretty safe place to be. Attackers had a hard time getting in. But they still had some options. They could go over the walls using ladders. They could break through the walls or doors. Or they could dig under the walls and try to get part of the wall to fall down. If none of those things worked, they could just camp outside until the defenders ran out of food.

Attackers sometimes brought large machines called siege engines with them to break through castle doors or walls. This was a heavy wooden beam with a metal cap. In the early 1500s, cannons (大炮) entered wide use in warfare. Cannonballs could dig into the base of stone walls and weaken them. The walls then fell under their own weight. As a result, castles were no longer needed.

On February 14th, 2000, my class went on a field trip to the beach. I had so much fun. When we returned to school, my teacher told me to go to the headmaster's office. When I got into the office, I saw a police officer. Suddenly I knew something was wrong. The police officer told me my mother was badly ill and we went to pick my sister up. After that, we went to the hospital and waited. Time went slowly. Finally, we got to see our mother.

On the next day, the headmaster came and told my two teachers what had happened. I was taking a rest that day. I knew it had something to do with my mother. I kept thinking that she either died or had gotten better. How I wished that she had gotten better. When my teacher took me outside, my sister ran up to me. She started crying, "She's gone. Teresa, mommy's gone. She's dead." I couldn't believe it. We jumped into the car and drove straight to the hospital. Most of my family were there. The silence was terrible. I knew I had to say goodbye.

Today when I look back, I still miss my mother very much, but I know that I will live. My mother was a strong mother, who had the biggest heart. My mother was an angel walking on the earth. I will always remember her as living. When someone is asked who their hero is, they usually say someone famous, like Michael Jordan or Britney Spears. When someone asks me who my hero is, I tell them, my mother. My mother lives every day. That is what makes her a true hero.
