[单项选择]Under pressure from animal welfare groups, two
national science teachers associations have adopted guidelines that ban
classroom experiments harming animals. The National Association of Biology
Teachers and the National Science Teachers Association hope to end animal abuse
in elementary and secondary schools and, in turn, discourage students from
mishandling animals in home experiments and science fair projects.
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.It is suggested toward the end of the text that
A. the seriousness of animal abuse in the classroom is unknown.
B. training teachers in animal care may contribute to reducing animal
abuse.
C. fewer animals have been used in experiments in recent years.
D. many biology teachers are not trained in proper care of animal.
