Coin confusion

Rachel looked through troubled eyes at her sister and said, "I wouldn't have thought Eric would be a thief." Her sister Sarah replied, "Whoa, that's a accusation to make against your best friend!"

Rachel remembered two days ago when she had brought out her coin collection for Eric to . At the end of that day, Rachel's mother asked her to do her a favor, so she asked her friend," Is it okay if I leave you for a few minutes?" Eric said, "Go ahead. I’ll clean up here," at the piles of coins on the floor.

When Rachel returned, it never occurred to her to her coins until two days later that she realized some quarters were .

Sarah said, "Why don't you just ask him?"

"Ask him what? Hey, best friend, did you my coin collection?" Rachel thought for a moment, if that would be a good idea. The theft of her collection left her with a feeling of "How could I have misjudged my friend's ?"

The next day Rachel went to Eric's house. Eric was acting funny sort of nervous, like he couldn't be . In fact, Rachel thought Eric acted like someone with a secret. Anger blossomed as Rachel watched Eric pretend to be kind, Eric had obviously stolen from her. Rachel finally could not stand it anymore and stood up. Suddenly, Eric ,"I can't stand it anymore!"

"Go to open it! I was going to wait until your birthday, but I can't wait." Slowly, Rachel lifted the top of the . Laid out in front of her were all of the quarters from her coin collection. Each quarter was in its own in a new collection case. Each quarter shone like it was new.

London has always been known for its "black fogs". In the winter of 1952, a milky white fog rolled into the city. As the smoke poured into the air, it was so hard to see that people had to walk in front of the buses to guide them. In this way, the most serious air pollution disaster in history began. When it was over, more than 4,000 people had been killed by the thick black smog.

New York City has had several London-type smogs since 1950. Each time, 100 to 400 deaths were caused by the smog. Although these smogs were not as deadly as London's, New York City has the worst air pollution problem in the United States.

In all the killer smogs, factories and homes poured smoke and fumes into the air from the furnaces. The chemical fumes combined with the water droplets in the fog to form harmful substances. These substances caused the illness of those who breathed the polluted air.

Usually, such harmful fumes rise into the upper air and are blown away by the wind. But sometimes there is an unusual weather condition called a temperature inversion. A layer of cold air remains near the ground as smoke and fumes pour into it. This is covered by an upper layer of warm air that acts like a lid. It prevents the polluted cooler air from rising. The harmful fumes pile up and make people ill. The smog may be so thick that airports are closed and chains of collisions occur on the highways.

Another type of smog occurs in Los Angeles. Here the weather may be clear and sunny. But stinging eyes and dry coughs show that harmful chemicals fill the air. The smog is due to invisible gases, mostly from automobile exhaust. Because these chemicals are changed by the sun high up in the air, it is called photochemical smog. It contains automobile exhaust fumes and nitrogen oxides changed by the sun's rays. Added to these are sulfur dioxide and other fumes from factories and oil refineries. Photochemical smog is found in many large cities all over the world.

Killer smogs don't happen very often, fortunately. But in Beijing, a combination of automobile exhaust fumes, home furnace smoke, and factory waste gases pours into the air. This may also happen in the suburbs, or out in the country, where large factories have been built. A number of harmful substances have been found in the air there. When these substances are breathed in day after day, the health of the population is affected.
