You’d better spend your time just on the things you find ______.

     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 all pollution 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.”

Then I realized I would have to 　25　 up summer baseball to handle the work schedule, and that meant I would have to tell John I wouldn’t be playing.
　　When I told John, he was 　26　 as I expected him to be. “You have your whole life to work,” He shouted. “Your 　27　 days are limited. You can’t afford to waste them.” I stood before him with my head 　28　, trying to think of the right　29　　that would explain to him why my dream of buying my mom a house and having money in my pocket was worth facing his 　30　 in me.
　　“How much are you going to make at this job, son?” He asked. “3.5 dollars an hour,” I replied.
　　“Well,” he asked, “is $ 3.5 an hour the price of a dream?”
