Animal welfare groups are apparently most concerned with high school students experimenting with animals in extracurricular projects. Barbara Orlans, President of the Scientists' Center for Animal Welfare, said that students have been performing surgery at random, testing known poisonous substances, and running other pathology experiments on animals without even knowing normal physiology. At one science fair, a student cut off the leg and tail of a lizard to demonstrate that only the tail can regenerate, she said. In another case, a student bound sparrows, starved them and observed their behavior. "The amount of abuse has been quite horrifying", Orlans said. Administrators of major science fairs are short-tempered over the teachers' policy change and the impression it has created. "The teachers were sold a bill of goods by Barbara Orlans", said Thurman Grafton, who heads the rules committee for the International Science and Engineering Fair. "Backyard tabletop surgery is just nonsense. The new policies throw cold water on students' inquisitiveness", he said. Grafton said he wouldn't deny that there hasn't been animal abuse among projects at the international fair, but he added that judges reject contestants who have unnecessarily injured animals. The judges have a hard time monitoring local and regional fairs that may or may not choose to comply with the international fair's rules that stress proper care of animals, Grafton said. He said that several years ago, the Westinghouse Science Talent Search banned harmful experiments to animals when sponsors threatened to cancel their support after animal welfare groups lobbied for change. The teachers adopted the new policies also to fend off proposed legislation—in states including Missouri and New York—that would restrict or prohibit experiments on animals. Officials of the two teachers organizations say that they don't know how many animals have been abused in the classroom. On the one hand, many biology teachers are not trained in the proper care of animals, said Wayne Moyer, executive director of the biology teachers' association. On the other, the use of animals in experiments has dropped in recent years because of school budget cuts. The association may set up seminars to teach better animal care to its members.

The future health of Americans may depend on it. Just this week, a study reported that life expectancy (预期寿命) has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in obesity (肥胖), smoking and high blood pressure. They also blame differences in health services around the country. In 2006, a study found that only four percent of elementary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that 22 percent of all schools did not require students to take any P. E. (体育课). Charlene Burgeson is the executive director of the National Association for Sport and Physical Education. She says one problem for P. E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class. But experts say P. E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way tp build a lifetime of activity. These days, teachers often lead activities like weight training and yoga. Some parents like the idea of avoiding competitive sports in P.E class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation. Why are schools recommended to give students certain time for sports？ A．Because different schools set up different physical education programs. B．Because the physical activity of children will influence their health in adulthood. C．Because nowadays children spend too much time on their studies. D．Because only four percent of elementary schools provided daily physical education.
