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.

Florida's E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler Heeb, who take turns working on the computer while helping out. with their family's clam-farming business on Pine Island, off Florida's southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body. The great majority of Florida Virtual Schoolers—80 percent—are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they barely passed the first time. The school's biggest challenge is making sure that students aren't left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years,Executive Director Julie Young made a priority out of what she calls "relationship-building," asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped. The completion rate is now 80 percent. Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-face contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say they'd prefer to have more interaction with their peers. Students and parents are quick to acknowledge that virtual schooling isn't for everyone. "If your child's not focused and motivated, I can only imagine it would be a nightmare," says Patricia Haygood of Orlando, whose two daughters are thriving at the Florida school. For those who have what it takes, however, virtual learning fills an important niche. "I can work at my own pace, on my own time," says Hackney. "It's the ultimate in student responsibility."

I have to believe that a great teacher is a great artist and that three are as few as there are any other great artists. It might even be the greatest of the arts since the medium is the human mind and spirit. My three teachers had these things in common: They all loved what they were doing; they did not tell, but stimulated a burning desire to know. Under their influence, the horizons sprang wide and fear went away and the unknown became knowable. I shall speak only of my first teacher because in addition to the other things, she brought discovery. She aroused us to shouting, book-waving discussions. She had the noisiest class in school and she did not even seem to know it. We could never stick to the subject. Our speculation (思绪) ranged the world. She breathed curiosity into us so that we brought in facts or truths shielded in our hands like captured fireflies (萤火虫). She was fired, and perhaps rightly so, for failing to teach fundamentals. Such things must be learned. But she left a passion in us for the pure knowable world and she inflamed me with a curiosity which has never left. I have had many teachers who told me soon-forgotten facts but only three who created in me a new attitude a new hunger. What deathless power lies in the hands of such a person？ 21. In the writer’s opinion, school life is usually . A. exciting B. interesting C. tiresome D. challenging 22. We can infer from Paragraph 2 that . A. it is easy to find great artists as well as great teachers. B. there are few great teachers but many great artists. C. the greatest artists are not easy to find; nor are the greatest teachers. D. being a great teacher is a great art to learn because teachers spread knowledge. 23. In the writer’s opinion, a good teacher should . A. teach students the fundamental things B. stick to one subject and be strict with students C. teach students the knowledge ranging the world D. arouse students’ curiosity and desire for the world 24. The writer’s first teacher was dismissed mainly because . A. her class was the noisiest in school B. she did not teach basic knowledge in class C. she let students shout and wave books in class D. she did not know how to teach basic knowledge effectively 25.
