导学全程练创优训练系列答案Earlier this year, the Environmental Protection Agency proposed a stricter nationwide health standard for smog-causing pollutants that would bring substantial benefits to millions of Americans. With a final rule expected by the end of this month, some opponents, mainly from industrial and oil-producing states, are pushing back. They say investments required to produce cleaner air are too expensive and not scientifically justified.
Lisa Jackson, the E.P.A. administrator, needs to stick to her guns. This is only the first of several political tests to come this fall, as she also seeks to tighten rules governing individual pollutants like mercury and global warming gases like carbon dioxide.
The health standard she is proposing covers ground-level ozone, commonly known as smog, which is formed when sunlight mixes with pollutants from factories, refineries, power plants and automobiles. Ozone is a major health threat, contributing to heart disease and various respiratory (呼吸道的) problems.
Ms. Jackson’s proposal—to reduce the permitted level of smog in the air from the current 75 parts per billion to between 60 parts per billion and 70 parts per billion—is sensible, no matter what industry’s defenders may claim. It had been recommended by the agency’s independent scientific panel but rejected by the Bush administration, which proposed a weaker standard.
Industry will have to make investments in cleaner power plants, and new technologies may be required. As it is, about half the counties that monitor ozone levels are not yet in compliance with current standards, let alone the proposed standard.
Fears about burdening industry raised by critics like George Voinovich, a Republican of Ohio, and Mary Landrieu, a Democrat of Louisiana, cannot be dismissed out of hand, especially in the middle of a recession (萧条). But the health benefits, E.P.A. says, far outweigh the costs, and the time frame for compliance (服从) is generous.

One evening I went out and left my 17-year-old son and his girlfriend in charge of his 8-year-old brother and 4-year-old sister. I left with complete confidence that the older children would do a wonderful job of babysitting the younger children. Later, I discovered that I was completely wrong.
I had decided to return home earlier than planned so that my son and his girlfriend could go out. I called home with this happy news．But instead of hearing his cheerful, grateful voice on the other end of the line, all I heard was the sound of a telephone ringing.
It was, I should point out, after 10 p.m., when the two younger children should have been in bed, and when the two older children should have been answering the phone. “I’ll give him a lesson, ” I said．I decided they must be outside．Why they might be outside at 10:30 on a winter night I had no idea, but it was the only explanation I could come up with.
Finally, in desperation（绝望）, I called his girlfriend’s house. His girlfriend answered．“Yes,” she said brightly, “He’s right here.”
He came on the phone．I was not my usual calm, patient．After all, one of the rules of survival for modern parents is that you can’t trust modern teenagers. “Where are the children?” I said. He said they were with him．They had done nothing wrong．My son had taken the younger children over to his girlfriend’s house just for ice cream and cake． Well, it turns out that I shouldn’t have believed it．It was only part of the truth.
The following Saturday evening we were at my parents’ home, celebrating my birthday．My oldest son gave me the children’s gifts --- a series of lovely color photographs of my children, dressed in their best clothes, and wearing their most wonderful expressions. They are pictures to treasure a lifetime, all taken by the father of my son’s girlfriend.
