Apparently,we are safe neither at home nor in the business office.We use water in both places,but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap,spraying from garden pipes,or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put allpollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”

I looked at my beautiful Christmas tree and sighed. It was time. The New Year was a week old and my tree still stood in the corner of our room with its collection of memories proudly displayed in a shower of colorful lights. I’d procrastinated(拖延,耽搁)long enough.

I got up, went to the garage and dragged all the boxes into the room. The garland(花环)was the first to come down. The tree looked naked(光秃秃的)already. I took the large ornament(装饰物)off next. They made a large pile on our bed. An hour later, our bed was covered with Christmas memories. Each pile contained an ornament along with its matching brothers and sisters from sets purchased many years ago.

I prepared the boxes and carefully placed ornaments in their protective packaging, pausing every few minutes to admire a favorite. “Hey, little Santa!” I held the Santa from my childhood. “Thanks for being my friend for almost fifty years.” He was a little ragged but still gives me a flood of wonderful memories. “Until next year, my dear friend.”

There was a collection of handmade ones. My children made in the their first years of school, more than twenty years ago. Made by tiny hands, they are far from perfect in design, but every year they go on my memory tree-memories of young giggles(咯咯地笑)on Christmas morning and a smiling face when they handed them to me when I came home from work. “Look what we made, Daddy!”

“Oh! It is beautiful. Let’s find a special spot on the tree for it.” Every year since, they are displayed.

A few hours after I started, the filled boxes were back in the garage, the room was vacuumed(用吸尘器清扫)and I sat staring at a barren(空荡荡的)corner. The room seemed so empty. It took me two days of work to assemble(收集)and decorate my tree, but only a few hours to take it apart.

My tree is like a good marriage or a great friendship. Like the tree, they take a long time to assemble and decorate with memories, but can be torn down quickly.

Every year I have to put my tree away, but not my marriage or friendships. I take great care of those. They get to glow in the corner of my life for as long as I live. I get to analyze my tree and find memories for a few weeks every year. I can do the same with the loves in my life every day. Take great care of your friendships and your marriage. Once they come down, they aren’t as easy to put back together as a Christmas tree. Stand them in that special spot in the corner of your heart and admire their glow.
