If you are interested in the news£¬it means you care about what is happening in your community and the world.But sometimes news can be upsetting.If you find out about sad news and it makes you feel worried or upset£¬what should you do? Dr.Harold Koplewicz£¬President of the Child Mind Institute£¬has some suggestions.
Sometimes£¬the news you watch on TV is not completely accurate.The news on TV is fast£paced.When bad news affects our nation£¬all of us need time to understand and process it.Your parents and your teachers can be your first sources to get information.
Even someone who is as strong and powerful as President Barack Obama weeps when he's very sad.It's part of being a human that sad events make us feel sad.That doesn't mean that we need to fall_apart£®It means that we just have to admit that we're sad and move forward.
People respond in different ways when facing sad news.There are certain kids who are very private and don't want anyone to see how they feel.But if you feel worried£¬talk to your parents and teachers£¬which can help you feel more comfortable.
If you still feel very nervous£¬another way to feel better is to take part in activities that are helpful to others.Go with your parents to the children's welfare institutions£¬or think of ways that you or your class can help others.
On the other hand£¬remember to go to sleep at the right time£¬play with your friends or go to the movies.It is okay to feel sad£¬but it's not good to stop doing the things you usually do.

Even before there were people£¬there were cases of air pollution.There were dust storms.Volcanoes erupted£¬sending ash and poisonous gases into the atmosphere.When people appeared on the scene and began their conquest of nature£¬they also began to pollute the air.They cleared land£¬which made possible even larger dust storms.They built cities£¬and the soot(úÑÌ) from their hearths filled the air.The Roman author Seneca wrote in AD 61 of the ¡°stink£¬soot and heavy air¡± of the imperial city.In 1257£¬the Queen of England was forced to move away from the city of Nottingham because the heavy smoke was unbearable.The industrial revolution brought even worse air pollution.Coal was burned to power factories and to heat homes.Soot£¬smoke£¬and sulfur dioxide(¶þÑõ»¯Áò) fill the air.
The good old days? Not in the factory towns.But there were large rural areas unaffected by air pollution.
With increasing population£¬the entire world is becoming more urban.It is the huge cities that are most affected by air pollution.But rural areas are not unaffected.In the neighborhoods around smoky factories£¬there is evidence of increased rates of spontaneous abortion(×ÔÈ»Á÷²ú) and of poor wool quality in sheep£¬decreased egg production and a high death rate in chickens.

One of the two major types of smog£consisting of smoke£¬fog£¬sulfur dioxide£¬sulfuring acid (H2SO4)£¬ash and soot£is called London smog.Indeed£¬the word smog is thought to have originated in England in 1905 as a contraction of the words ¡°smoke¡± and ¡°fog¡±£®
Probably the worst case of smog in history started in London on Thursday£¬4 December£¬1952.A large cold air mass moved into the valley of the Thames River.A temperature inversion placed a blanket of warm air over the cold air.With nightfall£¬a dense fog and below£freezing temperatures caused the people of London to put coal into their small stoves.Millions of these fires burned throughout the night£¬pouring sulfur dioxide and smoke into the air.The next day£¬Friday£¬the people continued to burn coal when the temperature remained below freezing.The factories added their smoke and chemical fumes to the atmosphere.
Saturday was a day of darkness.For twenty miles around London£¬no light came through the smog.The air was cold and still.And the coal fires continued to burn throughout the weekend.On Monday£¬8 December£¬more than one hundred people died of heart attacks while trying desperately to breathe.By the time a breeze cleared the air on Tuesday£¬9 December£¬more than 4£¬000 deaths had been caused by the smog.
Soot and ash can be removed by electrostatic precipitators(¾²µçÎü³¾Æ÷)£®Unfortunately£¬they use large amounts of electricity£¬and the electrical energy£¬which is hardly affordable for most of us£¬has to come from somewhere.Fly ash removed from the air has to be put on the land or water£¬although it could be used in some way.
The elimination(È¥³ý) of sulfur dioxide is more difficult.Low£sulfur coal is rare and expensive.Although sulfur can be washed from finely pulverized(·ÛÄ©»¯) coal£¬the process is expensive.There are also processes for changing dirty coal into clean liquid and gaseous fuels.These processes may hold promise for the future£¬but they are too expensive to compete economically with other fuels at present.They also waste a part of the coal's energy.
